Title : Effect of irrigation schedules and nutrient management practices on growth, yield and economics of transplanted autumn rice

Abstract :

The present investigation was carried out during autumn season of 2017 and 2018 at ICR Farm, Assam Agricultural University, Jorhat to see how varied irrigation schedules and nutrient management practices affect the performance of transplanted autumn rice. Results showed that different irrigation schedules significantly effect growth and yield of transplanted autumn rice. Application of 5 cm irrigation at 3 days after disappearance of ponded water (DADPW) resulted in higher plant height, shoot dry weight and root volume at different phenological stages. The highest plant height, shoot dry weight and root volume at different phenological stages were recorded by recommended doses of fertilizer (RDF) which was at par with integrated nutrient management (INM) treatment. With 5 cm irrigation at 3 DADPW, the mean maximum yield contributing characters and grain yield and straw yield were recorded. Application of RDF provided highest yield attributing characters and grain yield and straw yield which was statistically at par with INM. Among all the treatment combinations, 5 cm irrigation at 3 DADPW with the application of INM (I2F3) recorded the highest gross return, net return and B:C ratio followed by 5 cm irrigation at 3 DADPW with the application of RDF (I2F4).
