Abstract
Field experiment was conducted during the Rabi season of 2007-08 at the Crop Research Center of Govindh Ballabh Pant University Of Agriculture and Technology, Pantnagar , U.S. Nagar ( Uttarakhand ). The experiment was laid out in Factorial Randomized Block Design taking 16 treatment consisting of six genotypes/ varieties (YSH-401, RYSK-05-1, Ragani, RYSK-05-2, YST-151 and NRCYS-05-2 ) with three fertility levels (75% of RDF, RDF and 125% of RDF) and replicated three times. Amongst the six genotypes tested, genotype YSH-401 had significantly higher
primary branches, number of seed per pod 1000 seed weight and seed weight per plant. It yielded significantly higher over all other genotypes/ varieties except check variety Ragani that was 7.13 percent higher over Ragani. Genotype RYSK-05-1 attained higher plant height and dry matter accumulation per plant while genotype RYSK-05-1 had higher NPK content in different plant parts at harvest . Nitrogen
,phosphorus and potassium uptake by seed ,oil yield and oil content were also higher in genotype YSH-401 while lowest glucosinolate content was found in variety YST-151(64.68) followed by genotype NRCYS-05-2 (68.51). It was observed that oil content and glucosinolate content were decrease with increase in fertility level while seed, straw, biological yield, nutrient uptake, and oil yield were increased with increase in fertility level. 100 percent recommended fertility level alone could not be capable of exploiting the maximum potential of testing genotypes of yellow sarson. To harvest maximum potential of the crop it was observed that fertility level may be increase up to 125 percent or even more of
recommended fertility level.
