Production potential and economics of maize (Zea mays)- based crop sequences on farmers fields

Abstract

An experiment was conducted at farmers fields from 1993-94 to 1995-96 to evaluate the productivity and economic returns of 6 intensive crop sequences under optimum irrigation and other resource availability. Higher maize (Zea mays L.)-equivalent yield (18.56 tofinesfha) was recorded from maize-radish (Raphanus sativus L.)-onion (Allium cepa L.) followed by maize-toria (Brassica campestris L. var. toria)-potato (Solanum tuberosum L.) (17.84 tonnesfha) sequence (Allium cepa L.), whereas the traditional maize-wheat sequence had the lowest total productivity (9.80 tonnesfha). Land-utilization index, net profit (Rsfhdday) and benefit :cost ratio also followed similar pattern.
