Stability and economics of crop sequences under assured water supply .

Abstract

An experiment was conducted during 1981.-1986 to study the stability and economics of the multiple-crop sequences under assured water supply. The sequences included cereals, pulses, oilseed and forage crops. Sorghum [Sorghum bicolor 6.) Moenchl-wheat (Triticum aestivum L. emend. Fiori & Pao1.)-groundnut (Arachir hypogaea L.) was the most stable sequence, giving the maximum net returns. Inclusion of summer groundnut in the sequence increased the net returns. Short-duration pulses and ra- tooning of sorghum were highly unstable over period of time. Sorghum-gram (Cicer anerinu;n L.)-pearlmillet [Pennirehrrn glnucum (L.) R. Br. emend. Stuntz] (for fodder) was also productive and stable crop sequences. Judged from calories productivity sorghum-gram-pearlmillet (fodder) was the best sequence. Based on the protein productivity cowpea (fodder)-sorghum-groundnul was found to be the best sequence.
