Application Irrigation Water For Crop Essay - 3003 Words

1.1 INTRODUCTION Application irrigation water to crop is the most important recurring aspect in water management of crop which needs careful consideration. A crop gets its water by its root. Irrigation water is required when the soil is unable to supply moisture to crop.The objective of irrigation is to keep adequate water available to crops, or if water is in short supply, to use what is available most effectively (Miller and Donahue, 1997). Determination of an irrigation schedule or time of application of water is a complicated process. The computer programs have made it simple and easy. Using the methods/tools of irrigation scheduling made it simple and possible. Water can be applied according to the water needs of the crops. In the beginning the amount of water applied depth is small as root depth is in developing stage or small. During the mid-season, the irrigation depth need to be larger as root depth is growing larger and deep. Thus, it reveals that irrigation depth and the irrigation interva l varies with the crop development stages.In an arid and semi-arid region where rainfall is scarce makes irrigation system critical. There is no substitute for water. It is indispensable for human, animal and plant life. Hence it is necessary to develop, conserve, utilise and manage this scarce resource economically and critically so as to meet the ever growing demand for agriculture and other human development activities.

Friis (2012) reported that humans can only survive approximately one week without water, with the average daily consumption about 2.5 liters and overall daily usage about 400 liters (Friis, 2012). Water is employed for a variety of reasons, ranging from domestic to agricultural, to industrial, to thermoelectric and so much more. Two sources of water were identified by Kenny et al.

Abstract: Agriculture uses 85% of available freshwater resources worldwide and this percentage will continue to be dominant in water consumption because of population growth and increased food demand. In India agriculture, primarily dependsRead MoreCalifornia Is Going On A Four Year Drought875 Words   |  4 Pagesthe lack of water. Farmers’ use 80% of water the state produces, directly influencing their production (Mieszkowski, 2014). The country heavily relies on California for much of its produce such as tomatoes, nuts, avocados, strawberries, broccoli, grapes and various others (Cooley et al. 2015). In 2014, harvested acreage was 6.9 million acres, the lowest it has been for the past 15 years. Farmers are now being forced to use significantly less land then before, but also ditch old irrigation techniquesRead MoreEssay about Agricultural Effects of the Drip Irrigation System1587 Words   |  7 Pagesevaluates the efficiency, effectiveness, social, economic and environmen tal impacts of the drip irrigation system. The drip irrigation system has the potential to increase the agricultural productivity and also to reduce water usage required for irrigation. It is a system of pipes and tubing located under the soil. Water is passed through these pipes which end at near the roots of the plants. This makes the water loss minimal. Initial stage is designing the system and its installation follows it.

Not only is water quality a major concern, but current farmers must now monitor water quality and provide adequate crop protection measures to insure a good yield. Water availability is affected by falling water tables, droughts and stressedRead MoreWater Quality Guidelines For Agriculture1331 Words   |  6 PagesWater quality for different usages depends on type and concentration of dissolved materials in it. So, while a sample is deemed appropriate for drinking usage it may not be employed for other usages in industry or agriculture. Food and Agriculture Organization of the United Nations (FAO) has published the water quality guidelines for agriculture. The agriculture sector consumes about 94 percent of total annual water in Iran as the biggest stakeholder (Alizadeh and Keshavarz, 2005).

Briefly describe the complexity of international water use, using the Rhine River or the Aral Sea as an example. International law allows individual states the right to utilize rivers, lakes, and aquifers in an equitable and reasonable manner (Haftendorn, 2000, p.51). Of course, reasonable and equitable are open to interpretation and each sovereign nation has its own ideas about what is best, especially when other nations are adversely affected by that nations actions.
