Nitorgen and Sulphur Fertilization on Yield and Nutrient under North India condition

A field experiment was conducted during the winter (rabi) seasons of 2014-15 and 2015-16 at Janta Vedic College, Baraut (Baghpat), Uttarpradesh to study the effect of nitrogen and sulphur fertilizer on yield and nutrient uptake pattern of 'RGN73' Indian mustard (Brassica juncea L.). The experiment was laid out in factorial randomized block design with two factors. A (Nitrogen 80,120,160 kg/ha) and B (Sulphur 0, 20, 40, 60 kg/ha). Each replication 12 treatment combination of different levels of nitrogen and Sulphur and three replication application of 120 kg N/ha in combination with 40 kg S/ha resulted in increased silique length, higher seed/silique, 1000-seed weight and ultimately the seed yield over the control (80 kg/ha N, and 0 kg/ha S) but was found at par with 160 kg/ha significantly increased uptake of nitrogen (65.49, 39.68 kg/ha), phosphorus (14.29, 20.56 kg/ha), potassium (19.59, 97.44 kg/ha), Sulphur (9.46, 14.07 kg/ha) and Carbon (248.2, 865 kg/ha) during both the year in the seed and stover of the crop compared the control (80 kg N/ha). Among the different Sulphur levels 60 kg S/ha resulted in achieving significantly higher nutrient uptake in Indian mustard in 2014-15 and 2015-16. The cost of cultivation was found to be 2.10% and 2.17% lower with the combination 120 kg N/ha and 40 kg S/ha compared to 160 kg N/ha and 60 kg S/ha, hence it could be achieving higher yield levels and nutrient uptake in Indian mustard under North India condition.
