Drip irrigation also makes weed control more efficient because less water is applied between onion beds to satiate weeds, minimizing herbicide usage and costs. Read on to learn more about the varying systems and which are wasting the least amount of water. Furrow (flood) irrigation directs water down crop rows to water plants. Sprinkler irrigation sprays water fairly uniformly on the tops of crops, making it less beneficial for onion production in comparison to drip irrigation. An efficient irrigation system or method must consider the soil type and properties, field topography and the type of crops being grown. They keep the roots moist and avoid wet foliage. Water is lost to areas that don't need moisture to begin with, not to mention the extra water wasted through evaporation. (2000). Surface or flood irrigation is the least efficient manner of irrigation. Figure 1 shows a flow diagram for the selection procedure. (p. 8). 0 1 2. The sprinklers placed there, distribute the water across the fields. (c) Water Use Efficiency (ηu): (d) Consumptive use Efficiency (ηcu): Furrow Method. mainly the efficiency of this method of irrigation depends on type of soil and crop, etc. If there is no tradition in irrigation, the most simple irrigation method to introduce is basin irrigation. You can learn more about surface irrigation from this article. They are: As water is an Instrument of agriculture and it is a beauty of agriculture. Basin Method. Weeping Line/Soaker Hose. They may also be concealed under mulch or soil, if aesthetics are an issue. To gain the extra benefits of such technology, most important is adequate system design, alongside proper installation, operation and maintenance, regardless of the irrigation method used ( Hanson et al., 1995 ). Both of these types of irrigation methods result in significant water loss and runoff problems. Sprinklers spray water directly on onion leaves, increasing the risk of fungal and bacterial disease development while decreasing marketability. The following are the various types of irrigation efficiencies: (a) Water Conveyance Efficiency: (ηc). However, a full watering can tends to be heavy to carry and will require more bending on your part to direct the water to the base of plants. 1. Hope it helps you . A water efficient washer costs $400 more than a regular washer and saves 100 L of water for each load. Only the immediate root zone of each plant is wetted. They provide a soft, rain-like stream of water which is gentler on the soil. The portable sprinkler is the least efficient of all these watering methods. The ratio of the amount of water available (output) to the amount of water supplied (input) is known as Irrigation Efficiency. Very simply, water is delivered to the field by ditch, pipe, or or some other means and simply flows over the ground through the crop. However, there are many ways to water a garden, some of which will not only save you time and labor, but also help conserve water. Surface irrigation is also appropriate to use when there isn't much value to the crops that are growing on a piece of land. Because drip irrigation is a system that is designed to only irrigate the root zone, most people in the agriculture industry will tell you that this makes it the most efficient type of irrigation. Also known as wild flood irrigation. Below is the efficiency of all irrigation methods. We are seeing more and more drip irrigation used on smallholder farms and there is a good reason why – it is one of the most efficient ways to irrigate your crops! Many water wands come with a pressure valve which allows you to change the water pressure at the flip of the thumb. mainly the efficiency of this method of irrigation depends on type of soil and crop, etc. The selected actions describe the details of each practice and correspond to many of the practices on the Permit to Take Water application form, in the Schedule for Water Conservation Measures. Better spray irrigation: By use of traditional spray irrigation, water basically is just shot through the air onto fields. They also spray on the soil around the onion, providing an ideal environment for weed seed germination. Both systems can also be successful as means of fertilization. Instead of supplying water directly to the roots, the water is supplied overhead, usually in the form of downpour provided by sprinklers. University of Nebraska: Lincoln Extension Service. In addition, its extended neck permits you to water directly at the base of plants without bending over. Overall, this is a very efficient method of watering. agriculture. It is essential to analyze the differences in the sustainability of irrigation systems and which would best fit your farm—certain irrigation methods, when implemented and monitored properly, can increase sustainability by optimizing profits, water usage, and onion yield. Installing drip irrigation requires a large start-up cost; however, the saved water and profitability of drip irrigated onions can make the investment worthwhile (Shock, 2001).
