Field evaluation of drip irrigation for kinnow crop

A study was carried out in Hoshiarpur district of Punjab to analyze the factors contributing to the adoption/non adoption of drip irrigation system and to evaluate the performance of drip irrigation systems by determining the uniformity coefficient at the Kinnow grower's field. Water saving/scarcity of water, yield increase, labour saving, decrease in weed growth, energy saving, quality improvement, subsidy available and uniform irrigation were the major factors associated with adoption of drip irrigation as reported by 75–100 per cent of the Kinnow growers. clogging and leakage of the drip irrigation system were the most important problems faced by majority (85–100 per cent) in the operation and maintenance of drip irrigation system. According to 80 per cent of the farmers high initial investment was the major factor for the non adoption of drip irrigation system. Lack of knowledge and delays in getting subsidies were the other important factors for the non adoption of the drip irrigation. Majority of the farmers (85 per cent) had very good and excellent field emission uniformity as the Christiansen uniformity coefficient determined from their drip irrigation systems was above 0.85.
