Yield response of aman rice to transplanting geometry and seedlings per hill in South-western Coastal soil of Bangladesh
Abstract
In a condition of limited scope of horizontal yield expansion, rice yield can be increased by efficient utilization of land through proper transplanting arrangement with maximum number of plant population unit-1 area. Thus, the present experiment was conducted in the farmer’s field at Batiaghata upazila of Khulna district, Bangladesh during T. aman season (Jul-Nov) to evaluate the effect of transplanting geometry and number of seedlings hill-1 on growth and yield of aman rice (Binadhan-7, a short duration variety of its’ early harvest can create opportunity to cultivate winter crops in this region). The experiment had four types of transplanting geometry (single row rectangular system, single row triangular system, double row rectangular system and double row triangular system) and three levels of seedling hill-1 (3, 4 and 5 seedlings) with three replications. The results showed that individually transplanting geometry or number of seedlings hill-1 had substantial influence on yield attributes and yield but their interaction effect had non-significant influence on almost all measured parameters except number of tillers and effective tillers hill-1. The maximum grain yield (5.6 t ha-1) was achieved from double row triangular system yet the highest plant height, effective tillers hill-1, grain panicle-1, 1000 grain weight and straw yield were obtained from single row triangular system. In case of seeding hill-1, 3 seedlings hill-1 produced the highest grain yield (5.33 t ha-1) plant height, effective tillers hill-1, grain panicle-1, 1000 grain weight and straw yield. It can be concluded that double row transplanting geometry with 3 seedlings hill-1 can utilize the land efficiently for grain yield and be recommended for cultivation of Binadhan-7 in the coastal region of south-western Bangladesh.
