Abstract

                                Field experiments were conducted to optimize the fertilizer schedule for tomato under irrigated condition in red loamy sand soil. The encouraging response of tomato to N and K could be well visualized with significantly higher fruit yield. Application of 80-60-40 kg N2 P2O5 and K2O ha-1 was optimum in increasing the yield and uptake of tomato. The T.S.S was altered by P and K levels and not. by the N levels. The acidity was found to be independent of nutrient levels. The soil available IN varied markedly among the N levels while the P availability was influenced by P and K levels. The uptake of nutrients was markedly influenced by the N and K levels as compared to P fertilization.
