Tannin Acyl Hydrolase (E.C 3.1.1.20) commonly referred as tannase is an industrially important enzyme which is mainly used in the food, chemical, pharmaceuticals and beverage industry; it is produced by number of microbes, animals, and plants. In this study production of tannase was investigated using agro-residue, Azadirachta indica leaves as a substrate of hydrolysable tannin by potent tannase producer isolate Streptomyces sp.SKA1.

A community based survey was undertaken with an objective for documentation about the ethno-curative knowledge and practices among the Meitei community residing in East Imphal District of Manipur villages namely Khongman and Bashikhong. A household’s survey was conducted using a standard questionnaire.  From the result of the survey it was found that 17 numbers of healers of both genders were practising their indigenous knowledge in healing of aliments in spite of modern medicine.

A pot experiment was conducted to investigate the vegetative performances, chemical composition and feeding value of soybean under impact of water deficit and spider mites as well as the possibility to their overcome through imidacloprid treatment. The development of aboveground mass, root mass and biochemical composition of soybeans were influenced by the water deficit and mites, but the sensitivity of these parameters to the action and interaction of these stress factors was different.

The general objective of the study is to conduct evaluation trial of five (5) sweet sorghum lines under Pangasinan condition. Specifically, it aims to determine their agronomic characteristics and identify and recommend varieties that are suitable for ethanol production. This paper highlighted the results of the three (3) trials conducted from October 2007 to February 2009.

The present study analyses relationship between relative growth rates (RGR), leaf nitrogen and leaf phosphorus. A range of leaf attributes was measured for 17 herbaceous species in four contrasting habitats fortnightly from   July to September (2006-2007). All herbaceous vegetation in 5 randomly located plots within each of four sites was clipped at ground level and analyzed fortnightly during the study period. RGR shows positive relationship with leaf nitrogen and leaf nitrogen.

The present study was carried out in Manakudy estuary over a period of one year  May 2014 - April  2015. The collection was made on every month in the morning 7-9 a.m at regular intervals from the selected six stations. In each station, three spots were randomly fixed. Identified zooplankton species are grouped into Copepod, Rotifer, Cladocera, and Protozoa. The total number of 25 species were reported. Among these, 12 species belonged to Copepod, 5 species belonged to Rotifer, 2 species belonged to Cladocera and 6 species belonged to Protozoa. Copepod was found to be the dominant.

The sericulture industry is very unique and popular for its high valued textile fiber, agricultural outputs including, cocoons and cottage based labor intensive and for the production of high quality textiles. An attempt has been made to formulate a strategic model to recognizethe potential strength and challenges of sericulture in Raigarh district at Chhattisgarh state. We report results of the comparative studies relating to the silk production and productivity at Raigarh district from the silkworm species Antheraea mylitta and Bombyx mori.

The Greater Rann of Kachchh (GRK) is a marshy and highly saline area characterized by flat terrain, harsh climate and ecologically fragile due to very low soil moisture and high soil salinity.  Therefore, an attempt was made on a pilot scale to reclaim the Rann and accelerate the natural recovery process of two bets (upland area), namely, the Kuar and Mori bets. Some traditional techniques of land resource practices were applied for reclaiming the area in year 2001 and 2007.

The identification of the growth hormones in the D. alata’stuber was conducted to investigate the composition (mg/l) of auxin, gibberellin and cytokinin in the three sectional parts of the D. alata’stuber in order to understand the potential aspects of the other parts of the tuber to be used as the seed. The findings show that the head, middle and tail sections of the D. alata’stuber content at least one growth hormone with the concentration of averagely more than 2.5 mg/l. Auxin was found in all sections with a significant concentration of ~ 2.8 mg/l.

The present investigation was conducted in Beed and Nanded district of Marathwada region in Maharashtra State. The main objective of the study was to assess the relationship between profile of beneficiaries with their extent of participation and impact of NWDP. The data were collected with the help of pre-designed interview schedule by contacting 200 respondents i.e. 100 beneficiaries from watershed villages and 100 non-beneficiaries from non-watershed villages.
