![]() ![]() ![]() The SIP sprinkle systems are almost as efficient. They are the most efficient irrigation method in terms of both the volume of water required and the yield per unit of area irrigated as well as the yield per unit of water actually consumed by evaporation and crop transpiration. ![]() The SIP drip systems are designed to operate at pressure heads of 1 to 3 m and cost between $500 and $600 per ha. Simple to manufacture polyethylene layflat tubing of diameters between 16 mm and 75 mm and with thicknesses ranging from 125 to 900 microns is used for the pipe networks. In view of this we have developed a generic Small-plot Irrigation Product (SIP) line that includes three types of drip, two types of sprinkle, and a piped surface irrigation application system. To profit from growing high value commodity, vegetable, and horticultural crops smallholder farmers need affordable irrigation products to get the most " crop per drop " and net income from small-plot (0.1 to 1 ha) irrigation systems. In addition to significant amount of water savings, the above interventions have also yielded savings on electricity, reduced manual labour to irrigate fields and enhanced the productivity ensuring better economic returns to the farmers. The development of low cost technologies and its use for better irrigation scheduling is an important area of work which is receiving major attention. The water conservation measures adopted by companies range from direct seeding of rice, use of drip and sprinkler irrigation, rainwater harvesting and watershed management. The case studies included in the publication demonstrate the efforts of Indian companies (namely Coca Cola India, Pepsico India, Monsanto India, Jain Irrigation and ITC Limited) who have undertaken large scale measures to reduce the freshwater intake in agricultural production. The report Sustainable Agriculture Water Management highlights some of the best practices adopted by the industry in minimizing freshwater intake and enhancing food production. ![]()
