Rainwater harvesting is one of the important aspects which has been emphasizedagain and again at all levels. For agricultural growth, water is a crucial factor.However, only 44% cultivable land has been brought under irrigation and rest hasto depend on rainfall only. In uplands of hilly or plateau regions, which ishorticultural potential area, mainly suffers due to lack of irrigation water, eventhough occurrence of good amount of rainfall that is restricted to monsoon season.Rainwater harvesting in small ponds and then providing irrigation using someefficient system is one of the answers to the problem. But, higher seepage fromsuch ponds limits use of such water resources. Plastics lining (may be with LDPE,HDPE or silpauline) has become popular now-a-days. Method of lining with suchmaterial differs from one place to another as well as requirement. Proper method of
lining, life of such lining, protection from damages,etc.are some of the issues which are being researched upon at several places and recommended based on need of the location. Secondly, appropriate strategy for utilization of such costly water resources in upland or mid-land areas needs to be evolved for realizing maximum benefits. It includes water conveyance, irrigation method, water delivery and application devices, irrigation scheduling, and dynamic command area as per availability of harvested water in a particular season/period, economics,etc.The paper enumerates various achievements obtained in experimental farm aswell as in farmer's field in participatory mode at different locations under the AICRPonApplication of plastics inAgriculture as well as elsewhere.
