Three field experiments viz. fertility gradient experiment with fodder maize, test crop experiment with preseasonal sugarcane and test verification trial with preseasonal sugarcane cv. were conducted at at Central Sugarcane Research Station, Padegaon (M.S.), India during 2007 to 2011 to develop the Soil Test based yield target equations for newly released variety CoM 0265 and to test the validity of these equations on Inceptisols. The basic data of nutrient requirement, contribution of nutrients from soil, fertilizer and farmyard manure were calculated and the equations were developed. The per tonne of requirement of nitrogen, phosphorus and potassium was 1.38 kg, 0.44 kg and 1.64 kg, respectively. The yield targets of 175 t ha-1 and 200 t ha-1 were achieved with a variation of 4.7 and 5.2 % without FYM and 1.7 and 0.6 % with FYM indicating the validity of the equations. Application of fertilizers based on STCRC target 200 t ha-1 with FYM recorded significantly higher cane yield (201.21 tha-1).The same treatment application of fertilizers based on STCRC target 200 t ha-1 with FYM is found beneficial for highest net return return (Rs. 234337ha-1) and better B:C ratio (3.01).
