Abstract:
A field experiment was carried out at Research Farm, Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Faizabad (U.P.) during Rabi season 2015-16 to study the effect of different levels and sources of sulphur on growth, yield attributes and nutrient removal by mustard (Brassica juncea L.). The trial was laid out in Randomized Block Design. Seven treatments viz. RDF (NPK: 120:60:60 kg ha-1), RDF + 20 kg S ha-1 through SSP , RDF + 40 kg S ha-1 through SSP, RDF+ 20kg S ha-1 through Sulphur Bentonite , RDF+ 40kg S ha-1 through Sulphur Bentonite, RDF+ 20kg S ha-1 through Phosphogypsum , RDF+ 40kg S ha-1 through phosphogypsum with three replications on silt loam soils. The growth characters like plant height, number of branches were significantly higher under R.D.F + 40 kg S ha-1 through SSP as compared to other treatments. The yield components like number of siliqua plant-1 , length of siliqua (cm) , grain yield (q ha-1) and stover yield (q ha-1) were significantly higher under R.D.F + 40 kg S ha-1 through SSP. N, P, K & S content and uptake in crop were obtained higher with R.D.F + 40 kg S ha-1 through SSP which was significantly higher than rest of treatments. Thus, it can be concluded that a dose of R.D.F + 40 kg S ha-1 through SSP may be most suitable nutrient combination for achieving higher yield , better seed quality and economics of mustard.
