    PERFORMANCE OF TRANSPLANTED AMAN RICE UNDER DIFFERENT MULTIPURPOSE TREE SPECIES AS AGROFORESTRY SYSTEM
    (HAJEE MOHAMMAD DANESH SCIENCE AND TECHNOLOGY UNIVERSITY, DINAJPUR., 2007-06) AMIN, MD. HAFIZ ALL; Prof. Dr. Md. Sadrul Amin
    A field experiment was conducted at the Agroforestry Farm, Department of Agroforestry, Hajee Mohammad Danesh Science and _ Technology University, Dinajpur, during June 2006 to November 2006 to evaluate the performance of transplanted Aman rice grown under different multipurpose tree species at various shading condition. Five variety cv. BR10, BR11, BRRI dhan 33, BRRI dhan 39 and Sorna were cultivated under three different tree species namely, Black siris, Guava and Mango. The experiment was laid out in split plot design with four replications where tree species were in main plot and rice variety was in sub plots. The data were collected at 30, 45, 60 and 75 DAT (days after transplanting) and finally after harvesting. The significant effect of partial shade was found in number of effective tiller / hill, length of leaf blade, breadth of leaf blade and plant height at 30 DAT, plant fresh weight, straw- root fresh & dry weight, unfilled grain / panicle, 1000 grain weight and grain yield. The varietal effect was significantly observed on number of leaf / hill, length of leaf blade, breadth of leaf blade at 30 DAT, plant height & number of effective tiller / hill at 30, 45, 60 & 75 DAT, plant fresh weight, straw root fresh and dry weight, days to maturity, panicle length, number of grain / panicle, unfilled grain / panicle, 1000 grain weight and grain yield. The interaction effect was significantly found in number of leaf / hill, length of leaf blade, breadth of leaf blade at 30 DAT, plant height at 30, 45 & 75 DAT, number of effective tiller / hill at 45 DAT, plant fresh weight straw root fresh & dry weight, unfilled grain / panicle and grain yield. It was recorded that in partial shade condition the highest grain yield (3.78 t / ha) was found under Black siris which was statistically similar to that of Mango and the lowest grain yield was found (3.50 t / ha) under Guava. The highest plant height was recorded (62.90 cm) at 30 DAT under Mango which was statistically similar to that of Black siris and the lowest plant height was found under Guava at 30 DAT.
