    Abstract
    A field experiment was carried out at Mohabolipur, Basherhat under the Chahalgazi union of sadar upazila of Dinajpur District in front of Hajee Mohammmad Danesh Science and Technology University Dinajpur, during November 2016 to April 2017 to evaluate the yield and economic performance of BRRI dhan28 considering different distance of Eucalyptus tree base agroforestry system under cropland. The experiment was laid out following the Randomized Complete Block Design (RCBD) with three (3) replications. Total no of experimental plots were 18. The treatments of the experiment were T1 = Rice cultivation from one meter distance of the base of eucalyptus tree, T2 = Rice cultivation from two meter distance ofthe base of eucalyptus tree, T3 = Rice cultivation from three meter distance of the base of eucalyptus tree, T4 = Rice cultivation from four meter distance of the base of eucalyptus tree, T5 = Rice cultivation from five meter distance of the base of eucalyptus tree and T6 = open field (control). The data were recorded in the following headship plant height (cm), number of tiller hill-1 , number of effective tiller hill1 , number of non effective tiller hill-1 , Effective grain panicle-1 , Non effective grain panicle-1 , length of panicle (cm), 1000 grain weight (g), grain weight hill-1 (g), straw weight hill-1 (g), grain yield t ha-1 (g), straw yield t ha-1 (g), harvest index. In case of economic analysis the benefits and cost ratio was calculated. The data were analyzed statistically and means were adjusted by DMRT (Duncan’s Multiple Range Test). The results of the research revealed that significantly, the highest plant height (119.6 cm) was found in T1 treatment (one meter distance from tree base) and the lowest plant height (107.8 cm) was obtained from T6 treatment (open field). Again the maximum number of tiller per hill (20.41) was found in T6 treatment (open field) while the minimum number of tiller per hill (18.41) was obtained from T1 treatment (one meter distance from tree base). The highest number of effective tiller per hill (18.83) was found in T6 treatment (open field) and the lowest number of effective tiller per hill (15.85) was obtained from T1 treatment (one meter distance from tree base). Similarly both the maximum effective grain per panicle of rice (93.37) and the highest panicle length of rice (22.23cm) were found in T6 treatment (open field). Moreover, the highest grain weight per hill of rice (35.45 g) was found in T6 treatment (open field) and the lowest grain weight per hill of rice (29.78g) was obtained from T1 treatment (one meter distance from tree base). However, it was observed that rice from the five meter distance (T5) of eucalyptus tree based agroforestry production system gave the highest net return (71621Tk. /ha) followed by (68696 tk/ha) in rice from the four meter distance (T4) of eucalyptus tree based agroforestry production system. At the same time, the lowest net return (52225 Tk. /ha) was received from the sole cropping of BRRI dhan28 (T6). Higher net return was the result of higher gross return from the higher yield of rice along with the value of eucalyptus tree. The highest benefit-cost ratio of 1.91 was recorded from the five meter distance (T5) of eucalyptus tree based agroforestry production system followed by the four meter distance (T4) of eucalyptus tree based agroforestry production system and the three meter distance (T3) of eucalyptus tree based agroforestry production system. The lowest benefit-cost ratio of 1.72 was observed in T6 i.e. in sole cropping of rice BRRI dhan28. So, rice can be profitably cultivated from the five meter distance (T5) of eucalyptus tree based agroforestry production system.
