Effect of irrigation schedules on seed yield and economics of seed production of H 90/4-5 (male parent of pearl millet hybrid HHB-50) during summer.

摘要

A field experiment was conducted during the summer season of 2002 on sandy loam soil at Research Farm of Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana, India to study the effect of irrigation schedules (irrigation at all, 2 or one of the different growth stages: tillering, flowering and milking) on seed yield and economics of seed production of H 90/4-5 (male parent of hybrid HHB-50) pearl millet. The seed and stover yields with three irrigations, one each at tillering, flowering and milking, were significantly high; and each successive decrease in number of irrigations resulted in significant reduction in these parameters. Increase in number of irrigations improved the economics of pearl millet seed production in terms of gross monetary returns, net returns and benefit:cost ratio.
