Abstract:
The field experiment was conducted during 2016-18 at Hi-Tech Horticulture Unit at RPCAU, Pusa, Samastipur. The experiment was conducted in naturally ventilated polyhouse to determine the best cropping sequence to ensure round-the-year production and profitability of vegetables. The experimental design was randomized complete block design with 6 cropping sequence treatments and 4 replications. The 6 cropping sequences were; CS1: Tomato – French bean – Cucumber CS2: Capsicum– Brinjal - Cucumber, CS3: Tomato – Okra– Cucumber, CS4: Broccoli – Carrot– Cucumber CS5: Tomato – Cowpea – Green onion, CS6: Cucumber – Tomato – Bitter gourd. Significantly highest production (1009.00 kg/100m2/year) and production efficiency (2.76 kg/100m2/year) were recorded in the CS2; Capsicum– Brinjal - Cucumber, which was at par with CS3; Tomato– Okra – Cucumber with total production of 975.98 kg/100m2/year and production efficiency 2.67 kg/100m2/year, whereas, CS5: Tomato– Cowpea– Green onion gave the lowest cumulative yield (804.99 kg/100m2/year) and production efficiency (2.65 kg/q/day). Capsicum– Brinjal - Cucumber sequence gave significantly highest net return (Rs. 11508.85 /100m2/year) over all other cropping sequences. Benefit: cost ratio was highest (3.53) in Capsicum– Brinjal - Cucumber (CS2) followed by tomato – French bean – bottle gourd (CS1), whereas minimum BCR (2.36) was recorded in Broccoli– Carrot– Cucumber sequence (CS4). Hence under naturally ventilated polyhouse condition Capsicum– Brinjal - Cucumber cropping sequence was adjudged the most productive and profitable, which deserves adoption by farmers of Sub tropical sub humid eastern part of India.
