Irrigation & Water Systems

Green house technology for Vegetables

2012-11-26T12:29:00.001-08:00

Vegetable forcing for domestic consumption:

During winters in north Indian plains and hills, the temperature and solar radiations are sub-optimal for growing off-season vegetables –tomato, capsicum, brinjal, cucurbits, okra, cowpea, amaranth and chilli. In tomato, low temperature and low radiation cause puffiness and blotchy ripening. Hence, during extreme conditions of winter season (October-February) these vegetables can be well cultivated under polyhouse.

The protected environment could be well adopted in home gardens at slightly high altitude where winter is prolonged. A small-sized polyhouse can be made over uncultivable landscape, even on roof/terrace receiving sunlight for growing chilli, tomato, brinjal, summer squash and okra in pots and other containers. The high-priced vegetables –asparagus, leek, tomato, cucumber and capsicum – are most important crops for production around metropolis and big cities during winter season or off-season.

Raising off-season nurseries:

The cucurbits are warm season crops. They are sown in last week of February or in first week of March when night temperature is around 18-20⁰C. But in polyhouse their seedlings can be raised during December and January in polythene bags protected from cold winds and frost. By planting these seedlings during January-end or first week of February, their yield could be taken in one and one-and a half months in advance than the normal method of direct sowing. This technology fetches the bonus price due to marketing of produce in the off-season.

Similarly, in plains as well as in temperate regions of the country, the seedlings of tomato, Chilli, capsicum and brinjal can be grown under plastic cover protecting them against frost and severe cold. The environmental condition particularly increase in temperature inside polyhouse, may have hastened the germination and early growth of warm season vegetable seedlings for raising early crops in spring-summer.

Asparagus, sweet potato, pointed-gourd and ivy gourd are sensitive to low temperature. The propagating materials of these vegetables can be well-maintained under polyhouse in winter season before planting their cuttings in early spring-summer season for higher profit.

Basic requirements:

Selection of seeds: It is imperative to have better quality seed possessing genetic characters suited to the environment in which it is grown. Good vegetable seed must be true-to name, viable, disease- and pest-free, free from weeds, dirt and other foreign materials.

Selection of cultivars: Cultivars suitable for open field condition are usually suitable for polyhouse cultivation. But relatively rapid-maturing cultivars and high-yielding hybrids are ideal. The selection of cultivars and hybrids depend on plant type and their growth behaviour. Tomato cultivars and hybrids should be indeterminate type. The plants are grown upright as a single stem rather than bush. The cucumber cultivars should be unique. They should have only female flowering habit, with dark green parthenocarpic (seedless) fruits free of bitterness.

Vegetable Seed Production:

Seed production in vegetables is the limiting factor for cultivation of vegetables in India. The vegetables require specific temperature and other climatic conditions for flowering and fruit setting. Some vegetables are grown in one part of the country but their seed production is restricted to another part. To reduce such microclimatic condition a protected environment is essential. Summer squash requires a mild climate for flowering, fruit setting and fruit development, and seed formation. Therefore, its seed production is only restricted to hilly region of north India in summer season. But nowadays seed production of summer squash ‘Australian Green’ and `Pusa Alankar’ is also feasible in north Indian plains in a low-and medium-cost greenhouse. Similarly, seed production of highly remunerative crops –tomato,capsicum and cucumber – is also performed under protected environment. The maintenance of purity of different varieties/lines can be achieved by growing them under greenhouse without giving isolation distance particularly in cross-pollinated vegetables –onion, cauliflower and cabbage. To get proper pollination and fruit set in onion, summer squash, cucumber and bittergourd, the bee-hives are kept inside during flowering.

Vegetable cultivation in low-and medium-cost greenhouse is a technical reality in India. Such production system has not only extended the growing season of vegetables and their availability but also encouraged conservation of different rare vegetables. The seed production of vegetables under protected environment is also a major step to increase vegetable production in India.

How NOT to Motivate Employees: 10 Management Habits to Break Now

2012-11-22T18:39:00.001-08:00

Feeling unmotivated? Uninspired? Disengaged? You’re not alone. “There’s a lot of valid reason we’re feeling burned out,” says Holly Green, workplace management expert and best-selling author of the book More Than a Minute: How to Be an Effective Leader and Manager in Today’s Changing World.

“It’s because we are,” she says.

I recently spoke with Green about the amount of stress managers are under today to re-engage their employees in an increasingly stressful work environment. If employees think they’re the only ones who need a break these days, Green says, they should think again. “Managers are feeling the same way. And when you’re burned out, it’s that much harder to think about engaging someone else.”

So rather than add one more thing to the already-overstretched manager’s to do list, perhaps it would be easier to simply know what NOT to do…Green was kind enough to offer the following advice on how NOT to manage your employees.

Top 10 Things Managers Should NOT Do To Engage Employees:

Don’t Practice the Halo Effect. This is when a manager assumes that, because someone has one good quality, the person is great at everything, preventing managers from seeing the opportunities for improvement; similarly, managers should also avoid the opposite of the halo effect – the devil effect.
Don’t Humiliate or Demean Employees (especially not in front of others).
Don’t Withhold Feedback because you assume your employees already know where they need to improve or will “figure it out” on their own. “If you’re going to be a good manager, it is essential that you get good at giving feedback,” Green says. That means both constructive and negative feedback.
Don’t Underestimate the Power of Ongoing One-on-One Conversations to build trusting, more productive relationships with your employees.
Don’t Assume Your Team Knows What Winning Looks Like. “A manager’s most important role is to clarify what winning or excellence looks like, and then help people achieve it for themselves and the organization – you can’t over communicate in this regard.”
Don’t Assume People Understand Your Reasoning behind decisions. By the same token, don’t blame any decisions on “upper management,” “the HR department” or anyone else. Employees see right through that.
Don’t Forget That Praise is About Them, Not You. When recognizing employees, pause and consider what the individuals would want to receive and how they would want to receive it. “For some people, presenting to the senior executive team could be a big perk and considered a reward for a job well done; for others, this could be the worst possible and most stressful of all scenarios,” Green says. Likewise, don’t give lavish public praise to someone who is very private, a Starbucks card to someone who doesn’t drink coffee or tea, or buy a cake for someone with dietary restrictions.
Don’t Speak Negatively About Other Team Members, their peers or senior management and leaders.
Don’t Give ‘Sandwich’ Feedback. While many managers were taught to give sandwich feedback (saying something good, sneaking in something negative and then quickly saying something good again), this method only “leaves the receiver wondering what the heck was the point,” Green says.
Don’t Ever Stop Recruiting. “Folks need to be re-recruited and re-energized – especially after the past few years.”

Anything you would you add to this list? What “habits” have you broken (or would like to see others break)? DO share in the comments below!

Characteristics of Different Soil Types

2012-11-12T22:50:00.001-08:00

Sand, Loamy sand, Sandy loam

These are well drained and aerated and workable for most of the year. They are very light to handle and quick to warm up in spring. Unless they have a very high organic matter content they are prone to drying out too quickly, and additional watering will be needed. This extra watering will also help to wash out the plant foods and lime from the soil, so they are likely to be acid (except for some coastal soils). They are often referred to as hungry soils and need lots of extra feeding. With careful management however, they can be amongst the most productive soil types.

Medium loam, Sandy clay loam, Silt Loam

These are the average soil types. They achieve a good balance between the ability to be very productive and the minimum of attention. The medium loam group is probably the best in this respect.

Clay, Sandy clay, Clay loam, Silty clay loam, Silty clay, Silt

Although these soils are difficult to work and manage, they usually have good supplies of plant foods and lime. The main drawbacks are the high water holding capacity (which means they are late to get going in spring) and the effort required to work them. You will need to catch just the right weather conditions to avoid hard work and damage to the soil structure. The use of heavy machinery (and especially rotavators) should be avoided at all costs, particularly when the soil is wet.

Peat moss or Fen Soils.

Provided they are not too acid and have effective sub drainage, these are probably the best natural soils available. They are rich in plant foods, are easily workable and early. It is possible to convert your existing soil into peat type soil by adding large amounts of organic matter. Some of the keenest exhibition growers do just this. It can be time consuming and costly at first, but once you get there life becomes much easier. You must avoid making your soil too acid though, and careful choice of organic matter is needed.

Chalk soils and Limestone Soils

These are the soils that contain a high proportion of chalk or lime. So much in fact, that it overrides their normal particle size classification. They are often very shallow soils, and severely limit the types of plants that can be grown successfully in them. If you have a soil of this type and are not happy with the range of plants it will allow you to grow, probably the best thing you can do is move to a new area and check the soil out first. If you can't move, the most sensible course of action is to limit yourself to the plants that will grow in chalky soils. Trying to change the soil is usually an uphill struggle and quite expensive.

Black Mold Disease of Onions

2012-10-20T13:13:00.001-07:00

Black mold occurs in both colored and white onions in the field, during transit, and at storage. The causal fungus attacks many fruits and vegetables through wounds or during ripening.

Symptoms and Damage
Among the symptoms of black mold are black discolorations on the bulb and shallow lesions on the outer scales. Streaks of black mycelia and spores develop beneath the outer dry scales. In the advanced stage of the disease, the entire surface of the bulb turns black.

Cause
Aspergillus niger Tiegh.

Management Practices
Cure the onion bulbs quickly and provide good ventilation. Store in a cool place and not in boxes or bags.
Harvest the bulbs at maturity. Cure the onions quickly.
Storage condition should be cool and dry, with good ventilation.
Do not store bulbs in boxes or bags. Store the bulbs at 1-10oC.
Avoid bruising of bulbs during harvest, storage, and transit.

Farmers turn to sewage to irrigate vegetable crops

2012-07-12T20:22:00.001-07:00

By Imran Rana

Published: July 10, 2012

A DIRTY DEAL: 40% is the cost reduction in growing vegetables if they are irrigated with sewage, as compared to standard practices.

FAISALABAD: According to reports, farmers – particularly small landholders – have taken to using sewage water to increase crop productivity. Agricultural experts say that wastewater is fast becoming a cheap alternative to expensive fertilizers.

Agriculturists contend that the use of effluent has increased crop yields by up to 25%. Given such claims, most small farmers prefer wastewater for vegetable fields in place of expensive pesticides and fertilizers.

Farmers, while talking to The Express Tribune, added that tube well irrigation is fast becoming a ‘dream’ for agriculturalists because of the high price of fuel needed to power them. “The government is not giving farmers any incentives, as they do in India,” they complained.

Farmer Arshad Mahmood revealed that market prices of agricultural land with access to a source of effluent are much higher, as compared to without it. He also informed that the use of wastewater lessens the cost of production by a whopping 40%. “After irrigating fields with wastewater, crops do not need pesticides and fertilizers,” he said.

“Vegetables need frequent watering for growth, but there is no electricity to run tube wells. The only source available is to draw water using diesel pumps, which is unaffordable for small farmers,” he claimed.

Sewage contains certain essential nutrients like nitrogen, potassium and phosphorus, which are essential to grow crops.

Meanwhile, medical experts have warned that increasing use of sewage for irrigation purposes poses significant health risks for the human beings who consume produce from such farms.

Dr Shafqat Ali – an MBBS doctor – said that ‘food poisoning’ complaints arise when humans consume food from land irrigated by polluted water, which he says contains bacteria, parasites, viruses, toxins and carcinogens; along with the nutrients that attract farmers to their use.

He added that the incidence of such diseases increases when vegetable crops are fed wastewater and pesticides; however, merely the overuse of fertilizer also carries significant health risks.

“Farmers using wastewater fail to follow minimum standards for safety requirements for foods meant for human consumption. To irrigate agricultural land with municipal or industrial sewage causes serious diseases and harms the health of human beings,” said Punjab Agriculture Department District Officer Chaudhry Hameed, while concurring with Dr Ali.

He added that such practices are usually employed by vegetable farmers. “The easy availability of wastewater allows farmers to economically grow crops. Effluent provides both moisture and nutrients to vegetables, resulting in good yields and a lower cost of production,” Hameed informed.

Drip Irrigation to Solve Famine in the Sahel?

Posted by Tasha Eichenseher of National Geographic in Water Currents on September 1, 2010

Local vegetable markets in Niger, Benin, Burkina Faso, and Senegal, could be flush with produce, despite drought conditions, thanks to a new agricultural system that combines efficient irrigation with new varieties of plants, according to scientists speaking today at the African Green Revolution Forum in Accra, Ghana. (News via press release.)

Drought has plagued Africa’s Sahel region for decades, threatening nearly half of Niger’s population, estimated at seven million, with starvation this year. The majority of food grown in the Sahel is from subsistence farms that rely on rain.

Several agricultural nonprofits announced today they will work with locals to implement the new system, called the African Market Garden, on more than 7,000 small farms in 100 locations in the Sahel.

The effort comes after more than eight years of research and the successful management of African Market Gardens on 3,000 farms, according to scientists from the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), the Consultative Group on International Agricultural Research (CGIAR), and the World Vegetable Center (AVRDC).

Dov Pasternak, with the Niger branch of ICRISAT explains that farmers and local markets aren’t able to keep pace with rapid population growth and urbanization, in part because of inefficient water use.

In traditional small-scale agriculture in the Sahel, irrigation can take up to eight hours a day as water is hauled from local sources, such as the Niger, Senegal, and Chari Rivers. The new system replaces manual irrigation with a solar-powered pump that delivers water to drip irrigation systems from the rivers.

Funding comes from various international NGOs and foundations, as well as through the development of farm cooperatives in the region.

Israeli miracle in the Colombian desert

2012-06-20T20:54:00.001-07:00

They said it couldn't be done, but a group of Israeli agricultural experts have succeeded in helping local Colombian farmers grow potatoes in a harsh desert environment.

"From this desert you might receive stones, but not potatoes," that's what local farmers in Colombia's northern La Guajira desert said when presented with an Israeli proposal to grow potatoes in the region.

A year later, Israeli know-how and technology has won the day, and produced nothing short of a miracle as local farmers have harvested 11 tons of potatoes from the desert.

La Guajira is a coal-producing region, and the company that processes most of that coal financed the potato project as a world-first experiment to get the tubers to grow in a desert climate. Typically, potatoes only grow in cooler climates where the soil has sufficient moisture. The success in La Guajira is considered a world-first for potato farming in dry, hot climates.

The project was the brain-child of Isaac Gilinski, a Colombian Jewish businessman who is currently serving as Colombia's ambassador to Israel.

The son of Israeli immigrants, Gilinski knew well of Israel's agricultural prowess and, with the help of Israeli agricultural expert Avi Nachmias, determined to bring that expertise to his country. Nachmias and others trained local Colombian farmers and helped install an Israeli irrigation system.

Officials from the Israeli Embassy in Bogota who visited the new La Guajira potato farms said, "The locals were in shock over this miracle. The farmers here are very conservative by nature, so it was not easy for them to break old habits and try something new. But from their point of view, this was a tremendous success, since a local potato harvest will create a lot of new income."

Colombian officials are reportedly eager to repeat what they call the successful Israeli project in other parts of the country.

About drip Irrigation and installing drip irrigation system

2012-06-18T18:30:00.001-07:00

What is drip irrigation

A Brief History of micro irrigation
Drip irrigation, sometimes referred to as micro irrigation or trickle irrigation, has its roots in agriculture. In many parts of the world with limited water supplies drip irrigation was one of the few options available for irrigation. Its development depended on advancements in polyethylene tubing, and its growth was most rapid in arid and drought-plagued regions. Beginning in the late 1960's farmers discovered that by using drip irrigation they could increase yields while lowering water use. The 80's saw drip irrigation making the transition into commercial landscape, with mixed success; in today's market, however, drip irrigation is well trusted and used extensively in agriculture, and is actively utilized in commercial landscape and residential garden sites, providing a possible solution to some of our water management problems.

What is Drip Irrigation?
Drip irrigation is the slow, precise application of water and nutrients directly to the plants' root zones in a predetermined pattern using a point source. A drip irrigation, micro irrigation or trickle irrigation design can be customized to meet specific needs while maintaining an optimum moisture level within the root zones, efficiently conserving water that might otherwise be lost to non-growth areas, runoff, sun or wind, and providing the proper balance of water and air needed for successful plant growth. These benefits can be useful for any residential, commercial or agricultural installation, and may be critical for cities and municipalities that face water restrictions while aspiring to maintain or expand their green areas.

At the present time and as long as water is inexpensive, irrigation inefficiency and over-watering may be overlooked. Once water supply is low due to a drought and water restrictions are applied, the inefficiencies of a poorly designed and installed irrigation system quickly become apparent. For an irrigation system to be successful, it must include proper design, correct installation, the right component selection, the proper layout, and equally important, appropriate maintenance. One of the main advantages of drip irrigation systems over conventional irrigation systems is the flexibility to adapt to any layout above or below grade, in any location. This feature allows users and installers to customize an irrigation system to meet a specific need for a wide range of irrigation requirements.

Unlike drippers or drip emitters, "micro sprinklers" throw the water over a wide area, and are designed to be used in areas where drip emitters are not practical, such as large areas of groundcover and flowerbeds. Micro sprinklers offer many of the same benefits as drip emitters. Using low volume irrigation offers key advantages and benefits to both contractors and homeowners.

Conventional irrigation systems using sprinklers or bubblers are rated in gallons per minute (GPM). Drip irrigation, micro irrigation or trickle irrigationflow rates are in gallons per hour (GPH), such as 1 GPH or 2 GPH drip emitters. For example a popup sprinkler used on a lawn may be rated at 1 to 3 GPM (gallons per minute), or 60 to 180 GPH (gallons per hour) while drip emitters are rated at 1-4 GPH (gallon per hour) and micro sprinklers may be rated from 5 to 45 GPH (gallons per hour).

With conventional watering systems, water may be lost through runoff, low system uniformity and high rate of evaporation, blown away by wind or wasted on non-growth areas. Using drip irrigation water is absorbed slowly into the soil and directly into the root zone. No water is wasted on non-growth areas. By placing the drip emitters just at the plant root zone you can water using much less water and with better efficiency. This irrigation method allows the water to move deeper into the soil, encouraging deeper root growth. In addition, the low flow of drip system enables watering of large areas using a single water source.

Another advantage of using a low flow drip irrigation system is that high pressure is not required to supply water to the drippers and micro sprinklers. Most drip systems operate at about 15 to 30 PSI (pounds per square inch), while the average home has water pressures of anywhere from 40 PSI to 80 PSI. Consequently, with a drip system, you will not notice a drop in pressure when the system is operating.

Also, operating under low pressure allows drip irrigation systems to use drip tubing, drip emitters, drip fittings and other components that do not require glue, clamps or hard-to-connect components. In fact, most components of a drip system can be moved or reused. This is explained in more depth in other sections.

Advantages and Benefits of Drip Irrigation System

Water Efficiency:
By applying water only where and when it is needed, with less runoff and less evaporation from leaves and soil, the uniform application of water from drip irrigation systems can achieve high water savings.
Ease of Installation:
The system can be installed without special tools or glue, and with limited knowledge, making the installation a very simple process.
Reduced Pest Problems and Weed Growth:
Watering only the roots of your plants with drip irrigation cuts down on water-borne pests and fungal diseases that spread by water movement, as well as the germination of weeds in the area between your plants.
Versatility:
Low volume irrigation systems are designed for placement in both new and existing landscape areas, and are ideal for installation on difficult terrain such as on slopes, in oddly shaped areas, and on windy sites.
Root Zone:
One benefit of a drip irrigation system is the creation of a totally new and more favorable root zone environment because of the maintenance of a relatively constant soil moisture level. This has important implications for plant water requirements, tolerance and control of disease.
Economy:
Investing in a low volume irrigation system can save you money and significantly lower your water use.

Disadvantages of Drip Irrigation

No serious introduction to drip irrigation would be complete without a look at the disadvantages associated with its use:

The drip tubing can be susceptible to damage from rodents, and household pets.
A filter is required to guard against potential clogging of the small water passages of the drip emitters and micro sprinklers.
You cannot see a drip system working as you can see a conventional sprinkler system.
Each drip emitter creates a wetted area around each plant, so watering is more critical in replacing the water used by the plant to avoid stress.

There are other details about drip irrigation that make it the sensible way to water your landscape area. Here we have provided only a broad overview. To see all the details scroll back up to our main help menu and check out the other sections.
