ABSTRACT
On cauliflower, the effect of soil test crop response (STCR) was examined in the Mollisol region of North
India. Its primary objective was to create fertilizer guidelines by utilizing chemical and integrated nutrient management (INM) practices. The trial was split into two parts: first, a preparatory test was done on maize during the kharif season. Then, during the rabi season, cauliflower was used to test different combinations of fertilizers at varying fertility levels. The experiment aimed at determining how cauliflower
responded to combinations of farm yard manure, nitrogen, phosphorus, and potassium. To achieve this, a set of fertilizer prescription equations was formulated using both chemical and INM approaches. These equations took into consideration crop’s nutrient requirements, soil, fertilizer and the farm yard manure (FYM) efficiency. Using these equations, ready reckoners for fertilizer prescription were created and tested in real farm situations. Ultimately, the study found that the targeted yield approach was more effective than general fertilizer recommendations.
Key words : Cauliflower, fertilizer prescription equation, STCR, INM
