The paper uses VEC model to analyze the impact of international prices volatility on Chinese soybean spot and future markets before and since the outbreak of the global financial crisis.
This study attempts to examine the empirical relationship between trade and total factor producitvity (TFP) in the agricultural sector using both cross -sectional (across nine agricultural commodities...
Thirty-six Najdi ram lambs, weighing an average of 24 kg and circa 3 months old, were utilized in this trial to evaluate the effects of various alfalfa hay particle lengths in the diet on growth perfo...
In this research, socio-economic characteristics and information sources of the farmers performing sowing with combined sowing machine which is one of the conservative tillage methods and the farmers ...
Pakistan endowed a very poor industrial base at the time of independence in 1947. It was considered to emphasize more on import substitution policies to develop a strong economy. The new era of trade ...
The purpose of this study is to investigate the role of legislation in national parks protection and management in Turkey. As an introduction a brief summary of the development and legal basis of nati...
Reactions to artificial infection with Fusarium graminearum isolates and a new fungicide Swing Top were studied in nine winter wheat cultivars evaluated in field experiments at two sites for three yea...
Low quality water for irrigation can impose a major environmental constraint to crop productivity. Effects of water quality, irrigation system, irrigation rates, and type of amendment on the yield and...
Exchange rate is one of the major trade policy instruments used to correct current account deficit. This study used the standard computable general equilibrium (CGE) model developed by the Internation...
The aim of this study was to determine whether a difference existed between the income levels of farmers with EurepGAP certificates and farmers who produce conventionally (without a certificate). The ...
The health effects of organic vs. conventional foods have been investigated in several studies. In vitro analyses indicated better repair of bacterial DNA and decrease of cancer cells proliferation ...
