Evaluation of Different Organic Manure on Nutrient Content, Uptake and Yield of Mustard (Brassica juncea L) Crop

A field experiment was conducted during 2020-21 at Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) during Rabi season to evaluate the “effect of different organic manure on nutrient content, uptake and yield of mustard (Brassica juncea L) crop.”. The experiment was laid out in randomized block design with Eight treatments and three replications. Eight treatments viz. Control, 100% VC (8 tonnes per hectare), 100% FYM (10 tonnes per hectare),100% PM (10 tonnes per hectare),50% FYM + 50% VC + Natural liquid manure (Jeevamrit), 50% FYM + 50% PM + Natural liquid manure (Jeevamrit), 50% FYM + 25% VC + 25% PM, 25% FYM + 50% VC + 25% PM along with different management practices were implemented. The result revealed that the highest nutrient content (%) by seed (3.15 N, 0.511 P, 0.560 K) and Stover (0.601 N, 0.180 P, 1.48 K) and the highest nutrient uptake (kg ha-1) of all the three nutrients by seed (56.54 N, 9.17 P, 10.05 K) and stover (28.80 N, 8.63 P, 70.92 K)  were recorded with combined effect of FYM, VC with application of Jeevamrit viz., and 50% NPKS through FYM+ 50% N through VC which was statistically at par toT6. Reduction in nutrient supply resulted significantly lower uptake of N, P and K in the treatment which received only 100% FYM. Similarly, the maximum seed (17.95 q ha-1) and Stover (47.92 q ha-1) yield of mustard was recorded in the T5 treatment (50% FYM + 50% VC + Natural liquid manure Jeevamrit) treatment received 50% recommended doses of NPKS through FYM and 50% N through VC which was at par to T6 in which 50% FYM + 50% PM + Natural liquid manure (Jeevamrit) was applied. However, the lowest value found in control treatment (T6).
