Effect of tillage, seed bed preparation and FYM on yield, physico-chemical properties and economics of sorghum (Sorghum bicolour L.)

Abstract

A field experiment was conducted during the Kharif season of the year 2017-2018 and 2018- 2019 at College Farm, College of Agriculture, Navsari Agriculture University, Bharuch, Gujarat, to study the effect of tillage, seed bed preparation and FYM on yield and physico-chemical properties of sorghum. Two levels of tillage (Deep tillage with mould board plough and planking with cultivator and shallow tillage with cultivator), three levels of seed bed preparation (raised bed with three rows, raised bed with six rows and flat bed sowing) and two levels of FYM (No FYM, FYM 10 t/ha) were evaluated in split plot design and replicated four times. Deep tillage with mould board plough and planking with cultivator recorded significantly the highest girth of ear head, weight of ear head/plant, grain yield, straw yield, water stable aggregate, infiltration rate available N, P2O5, K2O, gross returns, net returns and BCR. Raised bed with three rows were recorded significantly higher yield attributes and yield but remained at par with raised bed with six rows. Application of FYM 10 t/ha recorded significantly higher girth of ear head, weight of ear head/plant, grain yield, straw yield, water stable aggregate, infiltration rate, available N, P2O5, K2O, gross returns, net returns and BCR.
