Abstract:
A two-year field experiment was conducted during the kharif season of 2021-22 and 2022-23 at Student’s Instructional Farm of Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya, Uttar Pradesh to evaluate the effect of different ages of seedling and double transplanting on the growth and yield of rice crop. Three different seedling age were taken as the treatment T₁-14 days old seedling, T₂-21 days old seedling, T₃-28 days old seedling and two popular high yielding varieties of rice V₁- DRR-44, V₂- Sahbhagi Dhan were used for the study.It was observed that different seedling ages and double transplanting substantially influenced the root morphology, biochemical activity as well as nutrient status of the rice crop. However, 21 days old seedling significantly reduced the detrimental effect of double transplanting on both the varieties by improving physiological traits which ultimately helped in obtaining higher yield. Thus, it is recommended that under double transplanting 21 days old seedlings are beneficial for the farmers to minimize yield losses under sanda cultivation.
