IMPROVEMENT IN LAND AND WATER PRODUCTIVITY UPON ADOPTING PRESSURIZED IRRIGATION SYSTEMS BY THE FARMERS IN VIDARBHA REGION (INDIA) – A CASE STUDY

摘要

Pressurized irrigation systems were found suitable to give more yield per unit of water used.rnAdoption of these systems in irrigated agriculture can boost agricultural production andrnimprove the soil ecosystem, water and fertilizer use efficiency and reduce labour requirement.rnThe present study indicated that the pressurized irrigation systems gave better results whenrncoupled with the modern cultivation practices like cultivation across the slope, contourrncultivation and cultivation on raise bed; in terms of enhanced productivity by 13 to 50 per cent,rnwater use efficiency from 0.90 to 3.86 kg/ha/mm during kharif season (monsoon cultivationrnseason) in cotton, soybean, green gram and pigeonpea. Similarly during rabi season (winterrncultivation season) yield of chickpea was enhanced by 33 to 48 per cent and water usernefficiency from 2.44 to 3.50 kg/ha/mm by providing one or two sprinkler irrigations over therntraditional practice of cultivation along the slope with flow irrigation. Drip irrigation systemsrnindicated the higher B : C ratio with net extra income in 30 to 40 per cent saving in water inrnhigh value crops viz. water melon, chilli, tomato, turmeric and ginger.rnFrom these results it is concluded that on farm adoption of the pressurized irrigation systemsrnwith modern cultivation practices and adoption of drip irrigation with specific crop geometry.
