Recent studies have shown that major grapevine viruses for the Mediterranean region are prevalent in the native cultivars that have been grown for long in Albanian vineyards. Infectious Degeneration disease complex caused by Grapevine Fan Leaf Virus (GFLV), and other viruses, comprises a common phenotype in the field, but GFLV detection in random samplings has shown low frequency.

Betel vine (Piper betle L) is  a perennial climber Betel vine (Piper betle L) is  a perennial climber cultivated for its leaf. In India, 55000 ha and in Karnataka 7143 ha area covered under this crop. This paper is the outcome of series of field visits made to the betel vine growing areas. Significant diversity observed in production aspects and also problems related to crop production. Lack of alternative standard for vine climbing, irrigation methods, fertigation, wilt, snail and un organized marketing are major problems in northern part of Karnataka.

The experiment was carried out at college farm, college of Agriculture, Rajendranagar, Hyderabad, to determine genetic variability, heritability and genetic advance estimates in upland cotton.

In Chad, the food security constitutes a problem insofar where the agricultural production cannot satisfy the demand. The main causes of this decline are often imputed to the climate whose the worsening remains certain, but also the no availability of resources genetic of the major cereals crops. Thus, some local varieties of corn are in the way of extinction because the producers cultivate the local and exotic varieties side by side, or they exchange their seeds and caused the loss of their genetic identity.

The study has attempted to analyse the suggestions expressed by the tribal farmers for better utilization of indigenous agricultural practices in Pachaimalai hills.

The objectives of the present investigation were to find out the correlation between thyroid abnormalities and environmental pollution, occupation, industrial area, endosulphan and roof of residence used by human population. Two study groups were surveyed for the study of the prevalence of thyroid diseases. One study group is from Dakshina Kannada and the other Kasargod Districts of West coast of India. A total of 398 subjects were surveyed. Questionnaires were prepared and distributed to conduct the survey.

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.

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).
