ANALYSIS OF GROWTH AND PRODUCTIVITY OF INDIAN MUSTARD (BRASSICA-JUNCEA) IN RELATION TO FYM, NITROGEN AND SOURCE OF FERTILIZER

A field experiment was conducted during the winter seasons of 1992-93 and 1993-94 at Anand to study the effect of FYM, nitrogen and source o f fertilizer on growth and yield of mustard [Brassica juncea (L.) Czer nj & Cosson]. The results showed significant variation in leaf area in dex (LAI), crop growth rate (CGR), dry matter production and seed yiel d. The direct effect of farmyard manure (FYM) was conspicuous in impro ving the growth of mustard. FYM application at 10 tonnes ha(-1) signif icantly increased the LAI, CGR and dry matter accumulation per plant a t almost all the stages during first year study (1992-93) and in poole d analysis. Similarly, nitrogen application registered maximum LAI, CG R at 75 kg level and RGR and NAR at 50 kg level at almost all the duri ng both years. Sulphur carrying source (Ammonium sulphate plus single super phosphate) increased all stages growth characters. Maximum dry m atter accumulation per plant and seed yield were recorded with highest levels of FYM (20 tonnes ha(-1)), N (75 kg ha(-1)) and source having S. Seed yield was strongly associated with LAI and dry matter accumula tion per plant at all the stages.
