It has to play a signifcant role in making India self-reliant in oilseed sector. At present contribution of India to the world acreage and production is 19.29% and 11.12% respectively. Productivity of rapeseed mustard in J & K is 6.98 q/ha which is 37.72% of global productivity and 67.85% of national productivity. Keeping in view low productivity of rapeseed mustard crop in J & K state, a study was undertaken with randomly selected 200 rapeseed mustard growers 100 each from subtropical and temperate zone of Jammu division covering Jammu, Samba, Reasi and Doda districts to ascertain the performance of rapeseed mustard crop under farmer feld conditions. Multiple linear regression model was applied to work out the factors affecting productivity of rapeseed mustard crop. The results revealed that proper irrigation, spray of insecticide, proper sowing method, thinning, use of basal dose of urea at sowing time and proper weed management signifcantly affected the productivity of Indian mustard (Brassica juncea) with R 2 value 0.534. The drivers of productivity of gobhi sarson (Brassica napus) were proper time of sowing and irrigation with R 2 value 0.253 while use of phosphorus and irrigation at proper time were found to be signifcantly affecting the productivity of toria (Brassica rapa) with R 2 value 0.757. The factors affecting the productivity of hybrid gobhi sarson were proper weed control and knowledge about different production recommendations with R 2 value 0.080.

Cereals contribute major share in total agriculture production. After cereals, oilseeds constitutes the second largest agricultural commodity in India accounting for 13% of the gross cropped area, 3% of the Gross National Product (GNP) and 10% value of all the agricultural commodities. Despite being the largest cultivator of oilseeds in the world, India imports about 50% of the requirements because of the life style changes in dietary pattern and increased per capita income. The growth in production of domestic edible oils (9.22 million tonnes in 2012-13) has not been able to keep pace with the growth in consumption and the gap between production and consumption is being met through imports. (MoA and FW, GoI 2014). India grows nine major oilseed crops, i.e. soybean, groundnut, sunfower, saffower, castor, sesame, linseed, rapeseed mustard and niger on an area of 27.02 million ha, with productivity of 1108 kg/ha (Vision document 2050-Indian Institute of Oilseed Research). Among different oilseed crops rapeseed-mustard is the second most important edible oilseed crop in India after groundnut. Rapeseed-mustard is a group of crops comprising rapeseed (toria, brown sarson and yellow sarson) cultivar of Brassica campestris; Indian mustard (Brassica juncea); black mustard (Brassica nigra) and taramira (Eruca sativa). Out of these cultivars Indian mustard fts well in cropping system of rainfed areas and accounts for more than 75% of the total area under rapeseed-mustard cultivation in India followed by toria, yellow sarson and brown sarson. Gobhi sarson is under cultivation over a limited area in HP, J&K and Punjab under irrigated ecologies. India occupies the frst position in area and third in production in the world, accounting for about 12% of the world’s total rapeseed-mustard "seed" and about 8.5% of the world's total rapeseed-mustard "oil". Indian contribution to the world acreage and production is 19.29% and 11.12% respectively (DRMR 2015). Rapeseed mustard is a major oilseed crop of rabi season in Jammu and Kashmir. In J&K total area under rapeseed mustard crop is 55236 ha and in
