Still majority of farmers are circled to cultivate local T. aman rice cultivars, but the overall yield is very low. Agronomic management can be a good option to boost up the yield potential of these local cultivars. This study was conducted to observe the influence of planting geometry on the yield of local aman cultivars. Study Design: Randomized complete block design. Place and Duration of Study: The experiment was conducted to find out optimum plant density of Original Research Article
