The present study revealed that single seedling hill-1 recorded significantly higher yield and its attributes as compared to other treatments of planting. This may be due to healthy and efficient individual plant growth at lesser seedling density. With the increase in number of seedlings hill-1, grain and straw yields increases up to 3-seedlings hill-1 but further increase to 5-seedlings hill-1 showed decreased trend. This might be due to less number of effective tillers m-2 and lesser assimilation rate at 5-seedlings hill-1. The higher yield with low seedling density might be due to higher percentage of productive to total tillers and more interception of light. Also, grain filling is the process of remobilization from stored reserves, particularly from stem, leaves, and from current photosynthesis. So, it may be inferred that the effectiveness of grain filling is decided by the conditions of particular tiller. Hence, planting of fewer seedlings resulted in higher grain yield (Figure 1 and Table 1). The result corroborates the findings of Faruk et al. (2009)
