Abstract:

Afield experiment was carried out to formulate the fertilizer recommendation for brinjal crop in inceptisol of (C.G.) during rabi season 2005-06. Mukta Kesi variety of Brinjal was taken as the test crop. Fertilizer (N and P₂O₅) adjustment equations formulated by these models for specific yield target (Y) with the use of FYM are.

FN = 1.30 Y - (0.55 SN + 4.86 t FYM)

FP₂O₅= 115-(13254.6-58.5Y)^1/2- (2.99 SP + 6.25t FYM)

FN = 312-0.55SN (For economic and maximum yield)

FP₂O₅= 89-2.99 SP (For economic and maximum yield)

The recommendation for maximum and economic yield were identical because the plateau defined a realistic maximum yield, reached well before the crop response became un-economic for added N and P.
