INFLUENCE OF ORGANIC MANURES ON GROWTH AND YIELD OF MINT, CHILLI AND INDIAN SPINACH USING GEOTEX VERTICAL FARMING TECHNOLOGY

Abstract

The experiment was carried out at the “Horticulture Farm” of Sher -e-Bangla Agricultural University, Dhaka, Bangladesh during December 2019 to May 2020 to study the effect of different organic manures on growth and yield of horticultural crops like mint, chilli and indian spinach. (7x4) sq feet vertical structure was used. Each pocket contains 4 kg growing media. Long lasting and eco friendly geo textile cloth was used to make pocket for crop plantation. Those pockets were attached with vertical structure. The experiment consisted of one factor and these are T 1 iii :Control; T 2 :2 kg vermicompost and 2 kg soil per pocket; T 3 :1.5 kg vermicompost, 0.5 kg coco fibre and 2 kg soil per pocket and T 4 :2 kg kitchen compost and 2 kg soil per pocket. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Data were recorded on growth, yield components and yield of mint, chilli and indian spinach and significant variation was observed for most of the studied characters. In case of mint the highest production from individual plant was recorded from T 3 (1.5 kg Vermicompost, 0.5 kg coco fibre and 2 kg soil per pocket) which was 151.40 g per plant. The lowest production from individual plant was recorded from T 1

(control) which was 80.00 g per plant. In case of chilli results revealed that the highest fruit production (88.43 g) was obtained from T 3 (1.5 kg vermicompost, 0.5 kg coco fibre and 2 kg soil per pocket) which was significantly different from others treatments. On the other hand the lowest fruit production (24 g) was obtained from T 1 (control) which was statistically similar to T 4 (2 kg kitchen compost and 2 kg soil per pocket) and the yield was 29.67 g. In case of indian spinach the highest production from individual plant was recorded from T 3 (1.5 kg vermicompost, 0.5 kg coco fibre and 2 kg soil per pocket) which was 290.66 g. The lowest production from individual plant was recorded from T 1 (control) which was 71.33 g.
