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 3 establishment methods viz., transplanted rice, direct seeded rice (DSR), and system of rice intensification (SRI) with different irrigation management practices namely Alternate wetting and drying (AWD), Critical stage approach, Continuous saturation and Farmers irrigation practice. SRI method of rice establishment practice registered significantly superior performance in terms of NDVI values (0.625), photosynthetic rate (22.66), chlorophyll content (3.63), at flowering stages over the rest of the establishment methods but leaf temperature (29.18) and transpiration rate (5.28) were higher in DSR followed by SRI method whereas, transplanted recorded lower leaf temperature (27.27) and lower transpiration rate (4.82). Among irrigation methods NDVI values (0.619), photosynthetic rate (22.39), chlorophyll content (3.67), were higher in AWD followed by farmer’s irrigation practice and lower values were recorded in critical stage approach. Leaf temperature (28.11) and transpiration rate were higher in critical stage approach followed closely followed by AWD and lower leaf temperature and lower transpiration rate recorded in farmers irrigation practice.
