Abstract

A field experiment was conducted during 2017–18 and 2018–19 at Chiplima, Sambalpur under West Central Table Land Zone of Odisha, to evaluate fertilizer doses under different planting methods in rice (Oryza sativa L.). The values of growth contributing characters like plant height, effective tillers/plant, and leaf-area index increased significantly under mechanical transplanting followed by system rice intensification (SRI) and drum seeding methods. The maximum grain yield, straw yield and benefit: cost (B: C) ratio were recorded with mechanical transplanting (6.5, 7.5 t/ha and 2.6) followed by SRI technique (6.3, 7.2 t/ha and 2.3) and were lowest with manual method of random transplanting (4.6, 5.3 t/ha and 1.8). Application of 120-60-60 kg N-P2O5-K2O/ha increased the panicle length (24.8 cm), filled grains/panicle (155), grain (8 t/ha) and straw (9.2 t/ha) yield and nutrient uptake by grain (113.3, 32.5 and 116.6 kg N, P and K/ha), being higher than the values obtained under soil test based fertilizer application, i.e. 100-50-40 kg N-P2O5-K2O/ha.
