M. O. FARUK, M. A. RAHMAN AND M. A. HASAN

A field experiment was conducted at the Agronomy Research Field, Hajee Mohammad Danesh Science and Technology University, Dinajpur during June to December, 2007 to find out the effect of age of seedling and number of seedlings hill -1 on the yield of short duration transplant aman rice named BRRI Dhan 33. The treatments consisted of four seedling ages viz. 2, 3, 4 and 5 weeks old and three levels of number of seedling hill -1 viz. one, two and three. Various seedling ages, different levels of number of seedlings hill -1 and their interactions significantly influenced the yield parameters. The highest effective tillers hill -1 , panicle length, grain, and straw yields were found in four weeks old seedling but the lowest results were found from the two weeks old seedling. Two seedlings hill -1 were the best performer in respect of yield and yield components. Effective tillers hill -1 , grains panicle-1 , grain and straw yields were higher than one or three seedlings hill -1 . The 1000-grain weight was unaffected by the seedling ages, number of seedlings hill -1 and their interactions. Finally, four weeks aged seedling demonstrated the best performance in respect of grain yield and this variety may preferably be cultivated with two seedlings hill -1 to obtain appreciably good yield in aman season.
