this study attempted to investigate the process and barriers of flow of technical information in kwpa [1] . a survey method was used to collect the data. interviews with some key persons were also conducted. the target population included both experts and technical managers, and the information output of technical departments. descriptive statistics and spearman's rank correlation coefficient w...

Insect pests in stored wheat cause significant losses and play an important role in the dispersal of viable fungal spores of various species including aflatoxin producing Aspergillus parasiticus. The problem of insecticide resistance in stored insects and environmental hazards associated with fumigants and conventional grain protectants underscore the need to explore reduced risk insecticides t...

abstract in this research, the comparative advantage of cereals including: wheat, barley and corn in cities of kerman, bardsir and baft was investigated by using domestic resource cost (drc), social cost benefit (scb) and effective protection coefficient (epc) index during 2005-2006 and effect of exchange rate changes, price changes and products costs on comparative advantage, were investigated...

OBJECTIVE The present study assessed the impact of the 2009 food packages mandated by the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) on perceived sales, product selection and stocking habits of small, WIC-authorized food stores. DESIGN A cross-sectional study involving in-depth interviews with store managers/owners. SETTING Small, WIC-authorized food store...

economic growth is the most important purpose of developing countries. each country can improve social welfare and access to international markets by increasing production potential. production can increase by two ways: the first one, using more inputs that raising production cost and the second one, improving efficiency that can produce more output with certain inputs or the same output with l...

Agriculture is the single biggest user of land and water in Morocco; however its performances are still low due to high rainfall variation and rates of soil productivity depletion. Increasing concerns about soil and environment quality degradation have raised the need to review existing tillage management systems and develop new systems for seed-bed preparation. Consequently, No-tillage is foun...

Wheat is the main crop and often a strategic crop in many European countries. From a historical perspective, we describe the transfer of "reduced height genes" (Rht genes) from Japanese wheat varieties to wheat varieties in Europe and their influence on the increase of the total wheat production in the last century. Historic pathways of Rht genes were influenced directly or indirectly by wheat ...

The objectives of the present study were isolation, identification and characterization of xylanase producing fungi, optimization of medium composition and cultural conditions for xylanase enzyme production using cheaper sources. The fungal strains were isolated from garden soil by serial dilution technique and Aspergillus niger was identified and isolated in pure form. In conformation screenin...

A production approach based on the translog cost function is used to analyze import demand for wheat differentiated by class and country of origin in the Japanese wheat flour milling industry. Results indicate that US wheat faces strong competition in the Japanese wheat market, but its multiple classes and end-use characteristics enable the US to preserve the largest market share in Japan. © 20...
