The Climate variability and proper production potential in agricultural sector allow increasing export earnings by focusing on agricultural exports' development. Comparative advantage measurement is one of very useful criteria for optimized resources' allocation in countries with an open economy and an important role in international trade. Comparative advantage shows a country's ability in goods' production and exportation with lower cost compared to other competitors.

The Solanum nigrum L. Leaves were selected to screen pharmacognostic and phytochemical studies. Plant material was collected from farmlands in Coimbatore district, Tamilnadu, India. Solanum nigrum L. is a well-known leafy vegetable and also a medicinal plant, which has been valued in ancient system of medicine. The leaf extracts were subjected to organoleptic, fluorescence analysis, physicochemical analysis and preliminary phytochemical screening. The study contributes to the development of standardization parameters of herbal drugs used in our system of medicine

In the present study, eight pure monoterpenes: citronellol, geraniol, linalool, eugenol, thymol, cinnamaldehyde, p-cymene and α-pinene were tested for their fumigant toxicity against four stored product pests, Callosobruchus analis, Sitophilus oryzae, Stegobium paniceum and Tribolium castaneum. Monoterpenes tested showed varying degrees of fumigant toxicity against different species of stored product pests but were highly dependent upon dosage and exposure duration.

Nutritional quality of a food is very important. The nutritional importance of seafood has increased substantially because of beneficial effects of eating seafood fats and oils. The present study deals with nutritional and microbial quality of edible marine fish Sardinella longiceps. The proximate composition of protein, carbohydrate and lipid content were analysed. The results of proximate analysis showed that landing center sample had higher protein content (22.50%) and carbohydrate content (3.02%) then the market samples. However market sample showed the higher lipid content (1.96%).

A naphthalimide derivative was successfully synthesized and characterized as an Al3+-selective fluorescent probe. An obvious red-shift of the signal was observed in the presence of Al3+ in ethanol solution. This proposed probe exhibited a dynamic response range for Al3+ from 1.3 × 10-6 to 7.0 × 10-6 M with a detection limit of 8.2 × 10-7 M.

The current study was conducted to develop Agrobacterium-mediated transformation protocol for mature seed-derived callus tissues of Citrus cultivar ‘GWZ’ (Gailiangcheng orange x Weizhang Satsuma mandarin) using gfp as reporter. Transformation experiments were performed with Agrobacterium tumefaciens strain ‘EHA-105’, harboring a binary vector ‘pBin19’.

This study aims to investigate the impact of leadership styles on organisational innovativeness in the Sri Lankan plantation sector, with organisational culture as the mediating variable. Using a self-administered questionnaire, data was collected from 235 estate managers based on the constructs identified in the literature. The findings provide partial support to the hypothesised relationships. Although studies between leadership styles, organisational culture and organisational innovativeness exist, they are mostly conducted in isolation.

Cassava (Manihot esculenta, crantz), is an important root crop in the tropics and substropics of Africa and Latin American. It is vegetatively propagated crop. Due to the following cycles of propagation, viruses are accumulated, which contributes to the decline of cassava yield and quality. Stem cuttings of four cassava accessions Six-mois, Rendre, yalipé and M61/033 were collected in experimental field and have brought to laboratory. Infected plants were thermotherapy treated by incubation of plants at 42°C/day and 38/night for 2 weeks.

The horse gram commonly known as kulith is a traditional unexploited tropical grain legume and well known for its hardiness, adaptability to poor soil and adverse climatic condition. The horse gram is a cheapest source of protein. Further it is also rich in minerals such as calcium. The present work is undertaken with a view to add value addition of horse gram by incorporating it in the extruded products using horse gram, maize and rice as an ingredient.

A survey of household energy consumption pattern was carried out in village Dandesar of tehsil Nowshera, district Rajouri (J&K, India). The major fuel types fulfilling the energy demand of local people in study area were wood, LPG, crop residue and dung cake. Fuel wood constituted the major share of consumption which was 100.74×106 kcal/month, while dung cake utilization was found to be least. The total fuel consumption in the study area was 111.49×106 kcal/month. The study concluded that income was an important factor in making fuel preferences at household level.
