Abstract
At Kumarganj, Ayodhya, Uttar Pradeshâs Studentâs Instructional Farm of Acharya Narendra Deva University of Agriculture and Technology, a two-year field experiment was carried out during the kharif seasons of 2021â22 and 2022â23. 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 shown that double transplanting and varying seedling ages significantly reduced nearly every yield component that was examined. viz; panicle length, panicle weight, number of grains per panicle, ear length (cm), grain yield per m2 (g), biomass per m2 (g), when 14 and 28 days old seedlings were double transplanted. 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.
