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

Abstract

<jats:p>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.</jats:p>

Assessing the impact of variety RKD-18 in Bundi district of Rajasthan through front line demonstration

“…This finding corroborates results of Poonia et al (2017) [3] . (2020) [6] . Fluctuations in yield observed over the years were mainly on account of variation in rainfall that will change soil moisture availability, sowing time and pest and disease attack.…”

“…

A study was carried out at different villages of Bundi district under CSS-MIDH during 2017-2018, 2018-19 and 2019-2020. Total 50 front line demonstrations were conducted on coriander in 25 ha by the active participation of the farmers with the objective of increase coriander production through improved technologies.
