Rice is a widely cultivated cereal crop that is traditionally grown in a flooded system under transplanted conditions due to its semi aquatic nature. Planting methods, water and nutrient management has a significant effect on growth and yield of crop. Crop growth rate was influenced by intercepted radiation and provide base for assimilation of photosynthates. However, water scarcity and rising labor costs prompt the search for alternative rice cultivation methods. Augmentation of crop growth and yield requires appropriate management practices. This document discusses the best alternatives discovered during the study conducted during rabi 2020-21 and 2021-22 at College Farm, PJTSAU. Hyderabad. The experiment is replicated thrice with establishment and water management methods, as main plots and nutrient management practices, in a strip plot design. Direct seeded rice with alternate wetting and drying (AWD) produced a higher yield (5530 kg ha-1) and yield attributes. Crop growth rate, net assimilation rate, and photo synthetically active radiation were found to be higher in AWD-sown direct seeded rice. Among the nutrient management practices evaluated, poultry manure applied plot yielded higher yields and supported the improvement of physiological characteristics.

Drum seeder, AWD, Poultry manure, CGR, NAR and PAR

The results of the study showed that direct seeded rice with AWD has supported better crop growth, intercepted higher PAR due to maintaining optimum plant geometry, enhanced NAR, accumulated more photosynthates, improved all yield attributing characters, and reported a 9% increase in the yield over transplanted rice. Among the nutrient management practices, substitution of 25% RDN with poultry manure improved grain yield by 11.2% than 100% RDN.
