Study of integrated nutrient management and weed control measures on mustard (Brassica juncea L.) and its residual effect on fodder pearlmillet (Pennisetum glaucum L) in North Western Rajasthan

Abstract

An experiment were conducted during the winter season of 2014-15 and 2015-16 at Bikaner, to evaluate the integrated nutrient management and weed control measures on mustard (Brassica juncea L.) and its residual effect on fodder pearlmillet (Pennisetum glaucum L). The highest values of different weeds, yield parameters like number of silique and seeds per siliqua which laid to the highest seed yield under the treatment 5t FYM + 100% RDF and 5 t FYM + 75% RDF + biofertilizer. Among the weed management sources application of 1 kg ha-1 pendimethalin reduced the weeds and enhance the yield attributes and also produced the maximum seed yield. The uptake of nitrogen, phosphorous and potassium also maximum under the treatment 5 t FYM + 100% RDF and 5 t FYM + 75% RDF + biofertilizer treatments. In residual study the green and dry fodder yield were significantly highest under all INM treatments over control and 100% RDF treatment applied in preceding mustard. All INM treatments enhance the uptake of nitrogen, phosphorous and potassium over control and 100% RDF. On the basis of net returns an application of 5 t FYM + 100% RDF and 5 t FYM + 75% RDF + biofertilizer were found superior to all the treatments.
