Dry matter partitioning of Rice crop as influenced by Date of planting and Nutrient Management

Abstract Dry matter accumulation reflects growth and metabolic efficiency of a plant, which ultimately influences the economic yield. A 2-year field experiment was conducted at the Agronomy research farm of Orissa University of Agriculture and Technology, Bhubaneswar, Odisha during 2018 (Y1) to 2019 (Y2) having subhumid climate. Experiment was designed to evaluate the effect of two date of planting (D1: 10 July, D2: 25 July) which were allotted to main plots and 3 combinations of Nutrient management (N1: STBFR, N2: STBFR + GM, N3: STBFR + FYM) allotted for Sub plots on Rice crop (Naveen). Early planting (15 days ahead) shows significant improvement in Leaf, stem, panicle over late planting while significantly higher drymatter accumulation in different plant parts were optimized under STBFR + GM method of nutrient management. Among all the plant parts Stem shows higher accumulation of dry weight than other plant parts, However Early planting and application of STBFR + GM was recommended for higher drymatter accumulation of Rice crop.
