A field experiment was conducted during the winter (rabi) seasons of 2015-16 and 2016-17 at Pantnagar, district Udham Singh Nagar, Uttarakhand, to study the effect of nitrogen and sulphur fertilization on yield and nutrientuptake pattern of ‘RGN 73’ Indian mustard [Brassica juncea (L.) Czernj. & Cosson]. The experiment was laid out in factorial randomized block design with 2 factors, viz. Factor A (nitrogen 80, 120, 160 kg/ha) and Factor B (sulphur 0, 20, 40, 60 kg/ha). Each replication comprised 12 treatment combinations of different levels of nitrogen and sulphur and replicated thrice. Application of 120 kg N/ha in combination with 40 kg S/ha resulted in increased siliqua length, higher seeds/siliqua, 1,000-seed weight and ultimately the seed yield over the control (80 kg N/ha and 0 kg S/ha), but was found at par with 160 kg N/ha and 60 kg S/ha. Increasing the levels of nitrogen up to 160 kg/ha significantly increased the 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, 14.07kg/ha) and carbon (2482, 865 kg/ha) during both the years in the seed and stover of the crop compared with 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 2015–16 and 2016–17. 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 adopted for achieving higher yield levels and nutrient uptake in Indian mustard under Mollisols of Uttarakhand.
