Fertilizers are one of the costly inputs in agriculture and development of nutrient efficient fertilizers is need of the hour. Keeping in view of the above, slow release coated urea fertilizers are developed and the N loss from different coated urea fertilizers in a Vertisol was studied in comparison with normal urea. The coated fertilizers used were neem, 4% pine oleoresin (POR), 35% nano-rock phosphate and 2% nano-ZnO coated urea. In later two cases nanoparticles were loaded over 4% POR coated urea during preparation. Application of coated urea fertilizers such as neem coated urea and pine oleoresin coated urea in a Vertisol reduced the ammonia volatilization by 27.5% and 41.1%, respectively. Similarly, reduction of NO 3-N leaching due to application of neem, resin, nano-rock phosphate and nano-ZnO coated urea were 18.3%, 28.0%, 25.7% and 35.1%, respectively. The reduction of N volatilization and leaching losses imparted by coated urea fertilizers could be a viable N source for crops. However field level validation experiments have to be carried out to assess the efficacy of these coated fertilizers in enhancing crop yield and nutrient use efficiency.

Organic Agriculture sustain and enhance the health of soil, plant, animal, human and planet as one and indivisible. The experiment was carried out at Agriculture experimental field, Nehru PG collage Lalitpur (U.P.) during 2014-15. Lalitpur district is a part of Bundelkhand plateau. Betwa River is the boundary between Jhansi and Lalitpur in the north. Most of the area is under the average elevation of 300 m to 450 m from the sea level, whereas some portion in south has an elevation above 450m. Its latitudinal extension is from 24°10'N to 25°15'N and longitudinal extension is from 78°10'E to 790°0'E. The experimental comprising four levels of Vermicompost, Farm Yard Manure and Rhizobium was conducted in the factorial randomized block design with 12 treatment combinations and three replications in 30 pots. Application of integrated nutrient management increased the seed & straw yield (kg/ha) as compared to control. Seed and straw yield (kg/ha) of fenugreek crop was found, the maximum 300 gm/pot of vermicompost (1433 kg/ha) and (9267 kg/ha) followed by FYM and Rhizobium. The Application of vermicompost (300 gm/pot) resulted in significantly higher nitrogen phosphorus and potassium uptake than FYM, Rhizobium treatment and control.

Present study was conducted during 2021-22 in four NICRA implementing districts of Madhya Pradesh. Main aim of the study was to know the knowledge level of NICRA beneficiaries regarding climate resilient technologies being advocated by the scientist’s implementing NICRA project in selected Villages. A survey was conducted among randomly selected 300 NICRA beneficiaries with the help of an interview schedule. The findings of the study conclude that knowledge level of respondents benefiting by NICRA has a significant relationship with selected profile characteristics and it also shows that majority of the NICRA farmers (63.0 %) had a medium level knowledge on climate resilient technologies followed by low (23.7 %) and high (13.3 %).Hence there is a need to strengthen capacity building activities targeted to improve the knowledge and skills of adopt climate resilient agricultural technologies for sustainable agriculture.
