Note:
FN, FP2O5 and K2O are fertilizer N, P2O5 and K2O in kg ha-1, respectively; T is the yield target in q ha-1; SN, SP and SK respectively are available N, P and K in kg ha-1 and ON, OP and OK are the quantities of N, P and K supplied through organic manure in kg ha-1.
Apply entire P2O5 as basal, N in four equal splits (basal, 30, 45 and 60 days after planting), 2/5th of K2O as basal and remaining K2O in 3 equal splits at 30, 45 and 60 days after planting. If the above recommendation are not able to be followed, adopt blanket recommendation as follows
Basal dose : FYM 25 t/ha, NPK 50:250:100 kg/ha
Borax 10 kg/ha, Zinc sulphate 50 kg/ha and Copper sulphate 3.75 kg/ha
Top dressing : N and K each 150 kg/ha in 3 equal splits at 30, 45 and 60 days after planting.
Foliar spray : Foliar spray of ZnSO4 @ 0.5 per cent thrice at 10 days interval from 40 days after planting.
Spray 19:19:19 + Mn @ 1 % at 60 days after planting.
Boric acid @ 0.3% at flowering and 10 days later |
