Krishi Vigyan Kendra, Khowai (Tripura) popularly known as Divyodaya Krishi Vigyan Kendra, Chebri has been working for the farming community since 1979 located at North Chebri village of Khowai district of Tripura, 8 km from district headquarter Khowai and 65 km from state capital Agartala. It has an area of 43.46 hectare for trial and demonstration including administrative building, soil and water testing laboratory, mushroom spawn production laboratory, bio control laboratory, piggery unit, poultry unit, duckery unit, dairy unit, fishery unit, agri-clinic, exhibition hall, audio visual hall, class room, guest house, training hostel, staff quarter, home science unit, library, nursery unit, crop field, IFS model etc. with a satellite centre at state capital Agartala. The different cropping pattern and demonstration units have been developed as per the needs of the district. Over the years, KVK has served a very useful purpose in changing the mindset of farming community for faster development of agriculture in the district.

During this long journey, it has created several mile stone in the district as well as in regional and national level. This KVK has put tremendous effort in popularizing Potato production from TPS; Popularization of HYV (Gomoti,Tripura Chikon,Tripura Nirog) of Paddy through SRI; Popularization of  Soil health cards among the farmers, Dissemination of climate resilient technologies,Entrepreneurship development through Vermicomposting and Honey production,  Food Processing Technologies; Popularization of  INM; IPM; IFS; Popularization HYV of tuber crops like Cococasia, Elephant Foot Yam and Tapioca; formation and management of SHG and Farmers’ Club, Seed Production of Cereals, Oil Seeds and Pulses, Entrepreneurship development through  Mushroom Production, Popularization of High Yielding Maize variety. HQPM, Introduction of Kuroiler, Gramapriya and Swarnadhara birds, Exotic Pigs, Mono and Mixed Culture of Fishes; etc.

Besides the mandated activities; KVK, Khowai (Tripura) has been implementing different central and state government projects like NICRA, NIFTD, NFSM (Paddy, Coarse Cereals and Pulses), NMOOP, IWMP, FLDs under IIVR, TPS Tuberlet Production Programme, skill development trainings under Agriculture Skill Council of India  etc. for greater benefit of the farming community.

Details of technology


Weed control in bitter gourd through Paddy straw mulching

 Use straw mulch in bitter gourd is done mainly to conserve residual soil moisture. Through the experiment it is observed that Water use efficiency   is 85%. It is also observed that the flowering stage initiated by 20 days earlier in comparison with control. More vegetative growth is also recorded in case of straw  mulching.  B:C ratio in case of  straw mulching it is 1:2.65  So, we can recommend the farmer to go for straw mulching as for them the previous crop of bitter gourd is rice, So they can use this straw for mulching purpose @ 5 t straw mulch/ha.






Cultivation of ginger through Raising Seedling


Treat the selected rhizome with mancozeb (0.3%) and quinalphos (0.075%) for 30 min. At the commencement of season, cut the single buds with small piece of rhizomes weighing 4- 6 g. Treat the single bud sprouts (mancozeb 0.3%, 3 g/L of water for 30 min) before planting fill the pro-trays with nursery (Sand, Soil, Vermicompost @1:1:1) and Trichoderma 10g/kg Plant the ginger bud sprouts in pro-trays seedlings will be ready within 30-35 days for transplanting.
