摘要

In this study, already developed pot based Hybrid Hydroponics Technology (HHT) (soilless) is experimentally tested by installing the same inside a micro-climatically controlled greenhouse to determine its effect on plant growth, yield, water & nutrient savings and cost reductions. It was observed that the effect of hybridization was much higher on the growth and yield of cucumber and tomato plants as the plants attained the fruiting stage 7 to 10 days earlier, the average yield of cucumber and tomato crops was 6.7 kg and 5.5 kg per plant which was significantly higher as compared to the existing hydroponics technology for the selected crop varieties. Water and nutrient savings under the HHT are about 90 % and 60 % as compared to non recirculation type hydroponics technology. Based on the estimated yields, the developed HHT has a break-even point of 4 to 5 years only thus making it economically feasible and affordable technology for off-season greenhouse vegetable production particularly at non-arable lands and at rooftops as urban rooftop farming technology in developing countries where growth of population pressure is higher and income of agricultural community is low.
