In India, millions of tones of livestock excreta are produced. Our study explores the potential of an epigeic earthworm Eisenia foetida to compost different livestock excreta (cow, buffalo, horse, donkey, sheep, goat and camel) into value added product (vermicompost) at the laboratory scale. Vermicomposting resulted in lowering of pH, electrical conductivity, potassium and C:N ratio and increase in nitrogen and phosphorus contents. Total K was lower in the final cast than in the initial feed. C:N ratios of the vermicomposts ranged from 16.2 ± 2.17 to 75.4 ± 6.84. Microbial activity measured as dehydrogenase activity in buffalo, donkey and camel wastes increased with time up to day 90. But in sheep and goat wastes, maximum dehydrogenase activity was recorded on day 60 and decreased thereafter. The cocoons and hatchlings production by Eisenia foetida in different excreta were also investigated. The greatest number and biomass of hatchlings was recorded in horse excreta followed by cow, goat and sheep excreta. Thus, cow, horse, sheep and goat excreta show potential as good substrates in vermicomposting using Eisenia foetida, although further research is required to explore the feasibility of use of

Research on Azotobacter chroococcum spp. in crop production has manifested its significance in plant nutrition and its contribution to soil fertility. The possibility of using Azotobacter chroococcum in research experiments as microbial inoculant through production of growth substances and their effects on the plant has markedly enhanced crop production in agriculture. Being soil bacteria, Azotobacteria genus synthesizes auxins, cytokinins, and GA–like substances, and these growth materials are the primary substances controlling the enhanced growth. These hormonal substances, which originate from the rhizosphere or root surface, affect the growth of the closely associated higher plants. In order to guarantee the high effectiveness of inoculants and microbiological fertilizers it is necessary to find the compatible partners, i.e. a particular plant genotype and a particular Azotobacter strain that will form a good association.

The study has analysed the changes in structure of rural credit delivery and inclusiveness of rural credit flow across states and social groups, along with identification of factors that influence the choice of credit source. The study is based on the unit level data of Debt and Investment Survey carried out by NSSO during 1992 (48 th round), 2003 (59 th round) and 2013 (70 th round). The structure of credit system has been assessed in terms of access of rural households to different credit outlets, share of formal credit institutions, availability of credit, and interest rate. The determinants of rural households' choice for credit sources have also been studied. The study has found that the structure of credit market has changed over time and the share of institutional credit has increased. The initiatives taken by the government have paid off and the flow of institutional credit to rural areas has increased significantly even in real terms. The indicators of financial inclusion have shown a sign of improvement. However, regional disparity and presence of informal agencies in the disbursement of rural credit is still persistent. Rural households' access to institutional credit is influenced by a number of socioeconomic , institutional and policy factors. In our analysis, the education, caste affiliation, gender and assets ownership have been found to influence the rural households' access to institutional credit significantly. A concerted effort and appropriate policy reform are required to make rural households' access to institutional credit neutral to caste, class and regions.
