AL Bijarnia, RS Yadav, PS Rathore, SP Singh, Bhawana Saharan and Ramesh Choudhary 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 weed, growth, yield attributes and yield of mustard (Brassica juncea L.). The highest dry matter of different weeds, growth parameters viz. plant height, dry matter accumulation and leaf chlorophyll, yield parameters like number of silique per plant and seeds per siliqua which laid to the highest seed and straw yield under the treatment 5 t FYM + 100 % RDF and 5 t FYM + 75 % RDF + biofertilizer. Among the weed management sources application of 1.0 kg ha -1 pendimethalin reduced the dry matter of different weeds and enhance the growth, yield attributes and also produced the maximum seed and straw yield. A strongly significant and negatively correlation was observed between total dry matter of weeds and yield but strongly and positively correlation was yield attributes and yield of mustard. Keywords: INM, biofertilizer, FYM, weed control, mustard 1. Introduction Globally, India accounts for 17.27 percent and 9.07 percent of the total acreage and production of rapeseed-mustard (USDA 2016) respectively. India is the third largest rapeseed-mustard producer in the world after Canada and China. This crop accounts for nearly one-third of the oil produced in India, making it the country’s key edible oilseed crop. In India, it is grown on 5.8 million hectare, with an annual production of 6.3 million ton ne during 2014-15. Rajasthan is one of the major mustard producing states in the country, with an annual production of 2.9 million tonne and area 2.47 million hectare during 2014-15. Soils of northwestern Rajasthan developed under harsh arid tropical climate and are inherently poor in organic matter, fertility and water holding capacity. So integrated nutrient management involving efficient use of organic manures, bio-fertilizers and inorganic fertilizers can substantially enhance crop production, while minimizing environmental pollution. The use of organic manure (FYM) or other farm waste is the tool to improve the physical, chemical and biological properties of the soil. FYM being the source of all essential elements, improves soil organic matter. FYM also plays important role inhabitating beneficial bacterias thus makes nutrients available to crops. In western Rajasthan, mustard area is expanding due to the availability of irrigation water from the Indira Gandhi Canal System. Working out balance fertilizer schedule through integrated approach of organic and inorganic can be an effective measure in boosting average yield of mustard in this region. In integrated nutrient management approach biofertilizer can play an important role. In intensive crop cultivation require the higher use of chemical fertilizer which are costly input. Mustard is grown on poor soils with poor management practices. Weed infestation is one of the major causes of low productivity. Yield losses due to crop weed competition in rapeseed and mustard have been estimated to the tune of 10-58 percent or even beyond 23-70 percent depending upon the type, intensity and duration of competition. Competition by weeds at initial stages is a major limiting factor to its productivity. Manual weeding at 3-4 weeks after sowing is the most common practice to control weeds in Indian mustard. But increasing wages and scarcity of labour compel to search for other alternatives and the important alternative to manual weeding seems to be herbicidal weed control. Materials and methods An field experiment wer conducted during the winter season of 2014-15 and 2015-16 at COA, SKRAU Bikaner (28.01 0 N, 73.22 0 E, 234.7 m above mean sea level).
