Abstract
A field experiment was conducted to know the effect of influence of different establishment methods and irrigation management on morphological and yield parameters in rice (Oryza sativa L.) at Agricultural Research Station Dhadesugur, during kharif 2017. The experiment was laid out in a split plot design and treatments were replicated thrice. Rice plants were grown under three establishment methods viz., transplanted rice, direct seeded rice (DSR), and system of rice intensification (SRI) with different irrigation management practices viz., Alternate wetting and drying (AWD), critical stage approach, continuous saturation and Farmers irrigation practice. Morphological parameters viz., plant height, number of tillers per hill, LAI (leaf area index), dry matter accumulation in different plant parts recorded significantly higher values in SRI method of rice establishment where as DSR recorded significantly lower morphological parameters. AWD irrigation practise have been reported with higher plant height (98.25 cm), number of tillers per hill (19.53), dry matter accumulation (78.93 g hill-1) and LAI (6.93). Higher values of yield parameters viz., higher number of productive tillers per hill (13.93), panicle length(22.72 cm), test weight (23.95 g), number of grains per panicle (149.92), grain yield (5096.97 kg ha-1) and straw yield of rice (5711.42 kg ha-1) was noticed in SRI method of rice establishment where as lower values were recorded in DSR at harvesting stage. Alternate wetting drying was found more significant on no. of productive tillers per hill (14.16), Panicle length (22.62 cm), test weight (23.81g), no. of grains per panicle (150.67), grain yield (4985.70 kg ha-1) and straw yield of rice (5488.56 kg ha-1), while lower values were recorded with critical stage irrigation approach at harvesting stage.
