Effect of integrated phosphorus management on growth, yield and quality of mustard (Brassica juncea L.)

A field experiment was conducted at Rajasthan College of Agriculture, Udaipur to study the effect of fertilizer P, FYM and microbial inoculum alone and in combinations on growth, yield, quality and nutrient uptake by mustard. Thirty two treatment combinations consisting of four levels of phosphorus (0, 20, 40 and 60 kg P2O5 ha-1) and two levels of FYM (0 and 5 t ha-1) and four levels of microbial inoculum (no inoculum, PSB, VAM and PSB + VAM). Application of 60 kg P2O5 ha-1, FYM @ 5 t ha-1 and PSB + VAM inoculation significantly enhanced the plant height, number of branches plant-1, dry matter accumulation, number of siliquae plant-1, seeds siliqua-1, test weight, seed yield, straw yield and oil yield of mustard over respective control. Integrated application of 60 kg P2O5 ha-1 + FYM @ 5 t ha-1 reported significantly higher dry matter accumulation plant-1, number of siliquae plant-1, seed yield, straw yield and oil yield. Application of FYM @ 5 t ha-1 along with PSB + VAM inoculation reported significantly higher number of siliquae plant-1.
