Abstract
Effect of Age of Seedlings at Staggered Planting and Spacing on Growth and Yield of Transplant Aman Rice (Cv. Brri Dhan 46)
Highlights
Farmers in Bangladesh generally grow transplant Aman rice by using seedling sown at one time in the nursery bed
Forty-five days old seedlings and 20cm × 20cm spacing produced the tallest plant at 65 DAT
All parameters studied at harvest were significantly influenced due to spacing except length of panicle, number of panicles hill1, 1000-grain weight and harvest index
Summary
Farmers in Bangladesh generally grow transplant Aman rice by using seedling sown at one time in the nursery bed. Stagnant water due to flood, delay in land preparation etc. The seedling age increases due to delay in transplanting, though they were sown at the same time. The age of seedling is an important factor because it has tremendous influence on the growth and development, tiller production, grain formation and other yield contributing characters of rice [1]. Their aerial and underground parts utilizing more solar radiation and nutrients [2]. The tillering habit and production of spikelets panicle-1 depends to a great extent on the spacing of transplanting which is responsible for the variation of yield in rice
