Abstract:
Irrigation being a necessity for crop growth and productivity is of paramount importance. In order to sustain crop productivity and profitability over the years in this era of increasing water scarcity, it is important to adopt ways with better water use efficiency and higher productivity. Micro-irrigation is one such approach which improves economic returns and can boost production by up to 400% especially in the in arid and semi-arid regions. In general, irrigation efficiency for most well-designed surface irrigation methods reaches 60%, while in sprinkler irrigation it reaches 75%, and it may reach 95% in surface and subsurface drip irrigation. With a greater crop production and higher water use efficiency than traditional irrigation techniques, micro irrigation maintains a constant flow of water in the crop zone. Drip irrigation is the most efficient and it can be practiced successfully to irrigate wide range of crop variety especially in vegetables, orchard crops, and cereal crops. Applicability and success of drip irrigation changes with soil type, climate and management of system of irrigation and hence it has to be tested for region specific. Micro irrigation helps to improves water use efficacy and grain yield.
