Economic Evaluation of Transplanted Rice as Influence by different Trellis Vegetables

Abstract
The aim of this study is to find out effects of different trellis-vegetables grown at the edge of the rice field on the productivity and profitability of transplanted modern aman rice BINA Dhan-7. The study design was held as a Randomized Complete Block Design (RCBD) since it was repeated three times. The experimental treatments were T1 = rice + bottle gourd, T2 = rice + white gourd, T3 = rice + yard long bean, T4 = rice + bitter gourd and T5 = rice + cucumber. The results revealed that grain yield was the highest (3.48 t ha-1) in rice + cucumber (T5) and the lowest grain yield (2.65 t ha-1) was found in rice + bottle gourd (T1). In terms of vegetable production, the maximum vegetable yield (21.33 t ha-1) was obtained from rice + bottle gourd (T1) and the minimum value (0.25 t ha-1) was received from rice + cucumber (T5) crop combination. Moreover, the highest rice equivalent yield (23.98 t ha-1) was found from rice + bottle gourd (T1) crop combination and lowest value (3.48 t ha-1) was found from rice + cucumber (T5) crop combination. The highest value of gross return (Tk. 316290 ha-1) was obtained from the T1 treatment (rice + bottle gourd) and the lowest value of gross return (Tk. 50835 ha-1) was recorded from the treatment T5. The maximum benefit-cost ratio (3.35) was recorded from T1 treatment and the lowest benefit-cost ratio (0.71) was observed in T5 treatment. Finally, the growing of bottle gourd production at the edge of transplanted aman rice BINA Dhan-7 cultivation approach will be a significantly beneficial production technique.
