The feasibility of co-composting coir pith with solid poultry manure was tested with and without lime and rock phosphate amendment. The results revealed that the composting process facilitated by poultry manure amendment brought about bioconversion of coir pith to a final product in 45 days and the final product possessed physico-chemical characteristics required for quality organic manure. C : N ratio, which is considered as a maturity index of composting process, reduced during the composting process, to 21.42. The results of plant test using cowpea as bioassay plant revealed that the compost reached adequate maturity from biological point of view for use as an organic input in crop production.

The two main aspects dominating the success of inoculation are the effectiveness of the bacterial isolate and the proper application technology. Scope An assessment of practical aspects of bacterial inoculants for contemporary agriculture and environmental restoration is critically evaluated from the point of view of their current technological status, current applications, and future use. This is done because there are windows of opportunity for new developments in applied research using renewable, non-contaminated natural resources and new venues for research. Special emphasis is given to formulations and polymeric carriers. This review concentrates on practical aspect of inoculation technology dating from 1998 to 2013. Earlier publications are mentioned only for clarification of a specific point. Conclusions This review discusses characteristics of a carrier for inoculants, formulations of inoculants including liquid, organic, inorganic, polymeric, and encapsulated formulations. Technical aspects include inoculation techniques (soil and seed application), mass culture production, bulk sterilization, seed coating, shelf-life, and effect of moisture. Future research venues needed are noted.

The well-known quote "education is the manifestation of perfection already in man" has been expanded to explain the process of knowledge acquisition and discovery. The views and experiences of many well-known scientists and thinkers in this line of thought are presented in this article.

In addition to the utilization of endosperm for edible purposes and extraction of oil, the outer non-edible fibrous portion of the nuts (coconut husk) is used for extracting coconut. fibre or coir, which is commerciality utilized for making value-added products such as mats, geotextiles etc. In the husk. coconut fibres are seen tightly packed along with nonfibrous, fluffy and light weight croaky material known as coir pith or coir dust, which constitutes about 50-70 percent of the husk. The composition and properties of coir pith vary (Moorthy and Rao, 1998) depending on maturity of coconut, method of extraction and disposal, peliod between ex:ttaction and use and environmental factors. Wide variations in C:N ratio of coir pith from 58:1 to ll2: 1 has been reported (Savithri and Khan, 1994). Retted husks yield coir pith with less nutrients Lhan that obt.a ined by mechanical processing of unretted husk. Coir...

Total community DNA was isolated from two separate vermicomposting tanks in triplicate at four different stages of the process: pre-decomposition (15th day), initial vermicomposting (45th day), 50-70% vermicomposting (75th day) and mature vermicompost (105th day). Alpha diversity measurements revealed an increase in bacterial diversity till the 75th day, which then declined in the mature vermicompost. Beta diversity comparisons showed formation of distinct, stage-specific communities. In terms of relative abundance, the Acidobacteria, Actinobacteria, Chloroflexi, Gemmatimonadetes, Nitrospirae, Planctomycetes, TM7 and WS3 groups increased until the 50-70% vermicomposting stage (p = 0.05). During the same time, the abundance of Bacter...
