An On-Farm Trial (OFT) was conducted in the year 2016-17 and 2017-18 to assess the resistance level of different okra varieties against yellow vein mosaic virus in Kharif season of Chatra district of Jharkhand. The experiment was conducted in vegetable growing village Gidhour in Gidhour block of Chatra district in Jharkhand. The trial was designed in randomized block design consisting of 20 replications with three technological option i.e. TO-I Arka Abhay (N100P60K50), TO-II Arka Anamika (N100P60K50) and-III Pusa Makhmali (N100P60K50). For assessment related to yellow vein mosaic, percentage infestation in 5sqm and yield q/ha and economic was considered. The lowest infestation of yellow vein mosaic virus was observed in Pusa Makhmali variety i.e. (3.8%) with yield of 132.5 q/ha. It was also found superior in terms of Gross Income, Net Income and Benefit: Cost Ratio followed by Arka Anamika and Arka Abhay, respectively. Farmers’ response was also positive in all respects except the availability of varieties in local market.

Front line demonstration was conducted during the years 2014-15, 2015-16, 2016-17 in NICRA adopted village Mardanpur in Arra Panchyat of Chatra Block in Chatra district of Jharkhand. The study was conducted to assess the effects of decomposition of paddy stable on productivity and profitability with soil health in local farming system as well as extra pollution of the technology to similar micro farming situation. The experiment consisting of two technology option TO-I: (Farmers Practice) Burning of paddy stable in field and collecting paddy stable for use as fuel of cooking and after onset of monsoon field prepare and transplant rice (Variety-Abhishek) with N80P60K30 TO-II: Decomposition of paddy stable 4.5q/ha after onset of monsoon in the month of June through rotovator and transplanted rice (Variety – Abhishek) with N60P45K23 in RBD design with 20 replication. The result showed that an average grain and straw yield of rice was 25q/ha and 74.80 q/ha in farmers practice in technology option TO-I where as technology option (TO-II) i.e. 28.33 q/ha and 98.84 q/ha respectively. Return for rupee spent was also higher i.e. 2.40 in TO-II as compared to farmers practice i.e. 1.85 (TO-I). It is due to (25%) reduction of chemical fertilizer in technology option (TO-II).
