An attempt has been made to study the market arrival and price behaviour of potato in Uttarakhand. The study is based on secondary data on wholesale monthly/weekly arrivals and prices for the period of 2003 to 2012. The seasonality in market arrival and wholesale price was analyzed using multiplicative model; the Fourier analysis was used to analyze cyclical variation in market arrivals and wholesale prices. Distribution lag model and Autoregressive model were used to study the relationship between market arrival and price of potato in major markets of Uttarakhand.

The purpose of the present study was to identify the various enterprises undertaken by the members of women Self-Help Groups in Almora district of Uttarakhand. The study also aims to determine the extent of entrepreneurial skills of women under Self Help Groups in Uttarakhand. Hawalbagh block of Almora district was selected purposively considering the entrepreneurial activities and availability of active and functional SHGs under various Government and NGOs. Two villages namely village Bakh and village Sar ka ali were selected using simple random sampling.

In the present study, methanol, ethanol and aqueous extracts of Cassia occidentalis were evaluated by employing various in vitro antioxidant assays. The aqueous extract of had shown highest total phenolic content (250mg/g), the further assays were carried on active fraction of aqueous that is fractioned ethyl acetate extract. The ethyl acetate extract of C. occidentalis had the most effective total antioxidant activity among the two separated extracts. The IC50 values of the extract and BHT were found to be 60.5 and 60.4 respectively. The ethyl acetate extract of C.

There is degradation in the forest ecosystem in the Uttrakhand hills and its sustainability is very important for the survival of humankind. There has been a loss of 268 sq. km of forest cover in Uttarakhand hills. The very dense forest cover has gone down to the tune of 86 sq. km whereas there is a tremendous loss of forest cover in moderately dense forests and it is to the level of 519 sq. km. Nainital has also lost 3 sq km of VDF and 107 sq. km of open forest(OF).

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.
