this study uses vector error correction model to examine the effects of oilseeds, crude oil and vegetable oil tariffs on vegetable oil consumer price. monthly data sets for the years 2004-2013 and var and vecm models were applied for this study. research findings indicates only a long term equilibrium relation between the study variables .the effect of vegetable oil tariffs on consumer and prod...

iran is located in dry belt of the earth and always involved with drought in different sections. drought has already caused many losses to natural plant cover, agriculture and human society. for drought monitoring, we can use some drought indecies. in this research, the standard index of annual precipitation)siap),sandardized precipitation index (spi) and palmer drought severity index (pdsi) we...

Tomato is an important vegetable crop and plays a major role in the food nutrition security of people Mali. Production has increased recent decades but improvement fruit yield quality remains suboptimal. Limited access to best-adapted tomato varieties local conditions, pests diseases are limiting factors for improving productivity. This study evaluated performance different entries their produc...

plants cover composition, condition, trend, production, and grazing capacity of the rangeland change annually. in this research, the role of temporal rainfall distribution on rangeland production was assessed. this research had down in the rangelands of ilam (with semiarid to semi humid climate) and qom and markazi (with arid to semiarid climate) provinces. by attention on plant cover maps in e...

INTRODUCTION We evaluated the microbiological impact of low-level chlorination (1 ppm free chlorine) on the production of ready-to-eat (RTE) vegetables by monitoring the microbiological quality of irrigation and processing water in two production plants over a 4-season period, as well as the microbiological quality of unprocessed vegetables and RTE product. Water samples were also characterized...

Background: Garden pea is a cool season vegetable crop cultivated extensively throughout the world. Besides nutritional quality it also boosts soils through fixation of atmospheric nitrogen. The most important task breeding to develop varieties with high and stable production, different maturity types resistance against biotic abiotic stresses. To fulfil these objectives, analysis genetic diver...

Japan’s oilseed sector is divided into two main components: 1) a large oilseed-crushing industry that produces vegetable oil and oilseed meal, and 2) industries using oilseeds for food, without crushing them for oil. In general, the oilseed-crushing industry is protected by tariffs on vegetable oil at the border, but receives no domestic subsidies. Oilseed production for food, in contrast, gene...

Soils used for vegetable production in Florida are sandy, have low organic matter content and fertility, and can support the growth of soil-borne pathogens. Some growers choose to apply compost as an antagonistic suppression approach to combat soil-borne disease effects on crop yields or to increase organic matter and improve soil fertility. The objective of this on-farm study was to determine ...

The flowering of grasses is a process critical to plant population dynamics and genetics, herbivore performance, and human health. To better understand the climate factors governing grass flowering, we analyzed the patterns of culm production over 25 years for three perennial tallgrass prairie species at Konza Prairie in Kansas, USA. The three species (Andropogon gerardii, Sorghastrum nutans, a...

The role of tomatoes as nutritive vegetable crop in the diet of most humans has been stressed or advanced by many scientists. This study therefore, assessed the profitability of tomato production using organic and inorganic fertilisers on a typical irrigated soil in Hong Local Government Area, Adamawa State, Nigeria, with the intent of ensuring a more acceptable measure of sustainability among ...
