Crop diversification in waterlogged rice field using gunny bag based soil columns produced 3–4 tonnes of kharif rice, 4.5–5.4 tonnes of rabi rice along with other vegetable crops worth Rs 0.5–3.0 lakh/ha with higher B : C ratio for cucurbits. Crop diversification in rice field using gunny bag/hessian based soil columns increased cropping intensity by 100–200 %, generated additional returns and increased employment opportunities. In this process, nearly 1500 to 5000 number of gunny bags (capacity 50 kg) can be used per hectare rice land in an economical manner. Even if 1.0% (0.4 M ha) of the total rice acreage in India and Bangladesh (40 M ha) is diversified, about 10 lakh tonnes jute fibre will be utilized. It will increase the marketing opportunities of raw jute fibre, provide nutritional and livelihood security to resource-poor farmers.
