Effect of different levels of zinc and farm yard manure (FYM) on the physico-chemical properties of soil and yield of green gram (Vigna radiata L). Var. laxmi-151

Abstract

The field experiment was carried out at Department of Soil Science, Sam Higginbottom University of Agriculture, Technology and Sciences, Allahabad, India during summer season (March to May) of 2016. The experiment was laid out in 3A—3 factorial randomized block design with 9 treatments in three replications. The cultivar this investigation was “LAXMI-151”. There were 9 treatment combinations under the study namely, T0 [Zinc0+FYM0] Control, T1 [Zinc@0%+ FYM@50%], T2 [Zinc@0%+ FYM@100%], T3 [Zinc@50%+ FYM@0%], T4 [Zinc@50%+ FYM@50%], T5 [Zinc@50%+ FYM@100%], T6 [Zinc@100%+ FYM@0%], T7 [Zinc@100% + FYM@50%], T8 [Zinc@100% + FYM@100%]. The recommended dose of fertilizer is i.e. 20:60:20 kg ha-1. It is concluded that the best economy of different treatment concerned, the treatment T6 (Z2 + FYM0) provides highest net profit of `16498.00 with cost benefit ratio is 1: 1.47 however, the minimum net profit of `3098.00 was recorded in the treatment T2 (Z0 + FYM2) with cost benefit ratio is 1:1.07.
