Fertilizer requirement as per the prescription equation(Kg/ha) for rapeseed

Injudicious use of chemical fertilizer detoriates the soil health

For var. TS-38:
T1 (FP): 40:35:15:: N:P:K kg/ha +2t FYM/ha; (12,30,25 kg Urea, SSP, MOP/bigha + 267 kg FYM/bigha)
T2: Only N, P, and K fertilizer on Soil test value
T3: N, P, K fertilizer (Urea, SSP and MOP) based on soil test values + FYM @ 2t/ha. Amount of N,P, & K fertilizer will be adjusted after analysis of initial soil and FYM.
For var. JT-90-1:
