摘要：Rice is the indispensable grain in the Indian food basket and contributes about 45 percent to India's foodgrain production. Nutrients are essential for the higher growth and productivity of plants. Post-green revolution, fertilizer applications played a pivotal role in increasing food grain production, especially in rice and wheat. Nutrient distribution and accumulation patterns in different plant parts are important to design sustainable fertilizer schedules. The present investigation was conducted in Kharif season 2017 at the JNKVV research field, aimed to analyze nutrient accumulation and partitioning patterns under IPNS-STCR based nutrient application. There were six treatment combinations including an absolute control, replicated four times in a Randomised Complete Block Design. Results revealed that the higher level of nutrient viz. nitrogen, phosphorus and potassium were accumulated in the shoot as compared to root at all the stages of rice, however, nutrient content and total uptake increased with the increased growth stage of the plant. Among the different nutrient management, treatment having 158:107:69 kg N:P2O5:K2O with 5 t FYM ha-1 performed better than all the others.
