Effect of Different Establishment Methods and Varieties of Rice (Oryza sativa L.) on Growth, Yield, NPK uptake and Soil Fertility after Harvest in Mollisols

The present investigation was carried out with four establishment methods (wet-direct seeded (Wet DSR), direct seeded aerobic (DSR-aerobic), direct seeded on furrow irrigated raised bed (DSR on FIRB) and conventional transplanting (TPR)) in main plots and eight rice cultivars (Pant Dhan 23, Pant Dhan 24, Pant Shankar Dhan 1, Pant Shankar Dhan 3, Pusa Basmati 1, Pusa 1121, Govind and Pant Dhan 26) in sub-plots in split-plot design. Results showed that TPR produced 4.3 % higher dry matter than Wet DSR. TPR produced 7.63 and 10.75 % higher grain yield than Wet DSR and DSR-aerobic, respectively. Available primary nutrients (N, P and K) as well as their uptake were higher under TPR than other establishment methods. Among varieties, maximum dry matter accumulation and grain yield was observed with Pant Shankar Dhan 3. N and K uptake was the maximum with Pant Dhan 23 while total P uptake was the maximum with Pant Shankar Dhan 3. Higher available P and K were associated with Pusa Basmati 1 and Pusa 1121, and Pant Dhan 23, respectively.
