Abstract

A field experiment was conducted during winter (rabi) season 201415 at the N.E. Borlaug Crop Research Centre of the Govind Ballabh Pant University of Agriculture and Technology, Pantnagar to study the effect of nutri- ent levels on yield, nutrient uptake and economics of Indian mustard [Brassica juncea (L.) Czernj and Cosson] cul- tivar RGN 73 in tarai region of Uttarakhand. Treatment consisted of 3 levels of nitrogen (60, 80 and 100 kg/ha), 2 levels of phosphorus (20 and 40 kg/ha) and 2 levels of potassium (0 and 30 kg/ha), which were evaluated thrice in a randomized block design. The highest seed yield (1.93 t/ha), nutrient (N : P O : K) uptake (99 kg N, 42 P O 2 5 2 5 and 172 kg K O/ha), net returns (37.13 103 /ha), gross returns (60.45 103 /ha) and benefit: cost ratio (1.54) 2 were recorded with application of 100 kg N + 40 kg P O + 30 kg K O/ha followed by 100 kg N + 40 kg P O + 0 kg 2 5 2 2 5 K O/ha and 100 kg N + 20 kg P O + 30 kg K O/ha treatments. 2 2 5 2
