Investigation of growth, yield and economics as affected by FYM and some foliar treatments under late sown wheat

Abstract

An experiment laid out in split plot design replicated four times consisted of 12 treatments, having two FYM levels i.e., FYM (10 t/ha), no FYM and six foliar nutrition (0.1% calcium chloride, 0.5% zinc sulphate, 2.0% potassium chloride, 20g/ha ethylene synthesis inhibiter 1- methyl cyclo propane (1-MCP) and water spray at post anthesis stage) along with control as no foliar spray. Soil Appication of 10 t FYM /ha resulted numerically higher value of soil moisture content at different growth stages, emergence count, dry matter, LAI, yield attributes and ultimately grain yield. Physiological response of wheat in terms of chlorophyll content (SPAD value), photosystem II efficiency (Fv/Fm), canopy temperature, leaf temperature and transpiration rate were also numerically superior with FYM application over no FYM application. However values of aforesaid parameters except canopy temperature at 90 and 110 days after sowing were statistically at par. All foliar spray treatments were numerically superior over no foliar spray. However foliar spray of Zinc sulphate (0.5%) at post anthesis resulted highest yield attributes and grain yield and significantly superior to no spray. Among all treatments, FYM+ZnSO4 gave highest cost of cultivation, gross return and net return. There was not significant interaction between FYM and foliar treatments with respect to all the aforesaid parameters.
