Rice is the major dominant crop in the asian continent and all over the world. A research was carried out at Dr. Rajendra Prasad Central Agricultural University, Pusa in kharif, 2018 containing four different levels of vermicompost (0 t/ ha , 1.25 t/ ha, 2.5 t/ ha, 3.7 t/ ha) and three levels (0 %, 100 %, 50 % Recommended Dose of Fertilizer) of fertilizer RDF were combined with each other and analyzed for nutrient uptake and efficiencies in pot cultured rice crop variety Rajendra Bhagawati. Study revealed that nutrient uptake in grain (446.03 mg/ pot N, 104.95 mg/ pot P , 112.06 mg/ pot K) and straw (303.81 mg/ pot N , 49.83 mg/ pot P, 578.78 mg/ pot K) and the total nutrient uptake i.e. N (227.67 mg/ pot ), P(0.083 mg/ pot ), K(690.84 mg/ pot) were superior in the combined application of 3.75 t/ ha vermicompost and 100% RDF over other and showed higher stability in case of apparent nutrient use efficiency in 3.75 t/ ha vermicompost and 50% RDF except potassium for balanced growth of rice crop and declining straight 50% cost off chemical fertilizer substituted with organic sources.

Climate change is the most severe problem that adversely affects crop productivity and negatively impacts soil microbial biodiversity, which is considered the key component of soil fertility indicators. Microbial biodiversity regulates all necessary functions to strengthen and maintain the stability of the ecosystem. Climate change primarily affects the crop microclimate, which in turn destroys the ecological balance and disrupts the ideal growth conditions for the crops and hampers the proliferation of microorganisms in the environment, thus decreasing crop production over a particular region. Climate change conditions such as higher temperature, rainfall and other abrupt conditions destroy the equilibrium between microbes, plants and the environment to a large extent, altering the plant-microbe interactions. Higher Carbon dioxide concentration favours the crop in photosynthesis and helps achieve higher productivity. Microbial respiration also enhances the carbon dioxide concentration in the atmosphere, leading to global warming and other potentially hazardous conditions. Mitigation strategies on crop, soil and land management measures are important to counteract the negative impact of climate change.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
