There is growing evidence that demonstrates the hazard of inorganic chemicals on the soil, ecosystem, and agriculture. The awareness of the public towards the health, environment, and economy prioritizes the search for alternate technology. The microbial world is the largest unexplored reservoir of biodiversity which performs variety of essential functions like nutrient recycling, environmental detoxification. Careful selection of the specific microbial species for the particular crop is integral for its biocontrol, bio fertilization, and phytostimulation. The beneficial microbes around the rhizosphere perform multiple functions like fixation of nitrogen, solubilization of phosphate, mobilization of potassium, improvement of the soil aggregation, resistance against pest and diseases, release of plant growth-promoting chemicals and hormones. The commercial administration of microbes inoculated bio effectors in the agriculture increases the productivity of the crop with no risk to the environment. Also, biotechnology applied with microbial genome widens the scope for developing resistance against a wide range of host specific pathogen. This review highlights the recent progress in the microbial world with the aim to increase the productivity of the crops maintaining a sustainable environment.

Groundnut (Arachis hypogaea) is an important food and oil crop grown during rainy season in Nepal. Ground nut has high potential in context to Nepal especially in terai and low hilly area. Ground nut is grown in upland in rain fed condition during rainy season and it is also grown in river basin as well. In context to Nepal, there are no high yielding varieties as other countries India and China. The Experiment conducted was done according to the NARC Research System. Different exotic genotypes and local Landraces were collected and Series of trail were conducted in successive year in different location under IET, CVT, CFFT and FAT. All trials were conducted in Random Complete Block Design (RCBD). In IET, the result depicted that ICGV 07240 genotypes was highest yielding genotypes (2416 kg/ha) among all the genotypes. In CVT, ICG 07240 showed high yielding genotypes in wide range of location with an average yield of 2128 kg/ha. Similarly, ICGV 07240 showed high yielding performance among 4 elite genotypes with an average yield of 2504 kg/ha. In GGE biPlot ICGV 07240 was best performing genotypes overall the tested location. In 2018, ICGV 07240 was release as Sambriddhi with 52.88 % fat and 27.32 % protein. . This variety may be a new variety for the ground nit growing farmers and in future this variety may play pivotal role to meet the national demand of the groundnut.
