Impact of Technology Demonstration on Productivity of Greengram (Vigna radiata L.) in North Eastern Ghat Zone of Odisha

Abstract

The study was conducted to recognize the technological impact of proper package of practice for the production and productivity of Greengram in comparison to the traditional practices followed by the farmers of Ganjam district of Odisha. To enable impact assessment 100 farmers of which 50 farmers followed technology demonstration and 50 followed traditional method of cultivation were selected for the study. The results of technology demonstrations showed that farmers got increased productivity of Greengram notably by switching over to improved variety and adoption of improved production technology. From the experiment it was observed that the improved Greengram variety IPM 02-14 recorded the 42.5% higher yield compared to the local variety PDM-139. Technology gap and the technology index values were 230 kg/ha and 23%, respectively. Farmers are experiencing yield loss due to the high incidence of yellow mosaic vein diseases of the crop. The increment in productivity of the crop under technology demonstrations was not only due the adopting improved variety which is resistant to yellow mosaic vein diseases but also following other attributing factors like seed treatment with bio-fertilizers, proper seed rate, application of herbicide, judicious dose of fertilizers and plant protection measure.
