the purpose of present work is to survey cultural and social factors affecting the attitudes of shirvan and chardavol county farmers toward agricultural water management. data was gathered through a field research and survey, using interviews and the questionnaire that was prepared for this purpose. the statistical population consisted of all the farmers (wheat cultivators) of shirvan & chardav...

due to the conservational agriculture as a factor of increasing food security and sustainable agriculture, understanding the determinant factors in the farmers' decision making to enhance adoption scale of conservational agriculture, is quite important. therefore, the current study attempted to investigate the effective factors and barriers to agricultural technology adaption among the whe...

Until now, little attention has been paid to the geographic distribution and evaluation of genetic diversity of durum wheat from the Central Fertile Crescent (modern-day Turkey and Syria). Turkey and Syria are considered as primary centers of wheat diversity, and thousands of locally adapted wheat landraces are still present in the farmers' small fields. We planned this study to evaluate the ge...

The effect of flooding can be a serious problem for wheat farmers, even at dry land condition. Amount of flooding damage depends on duration flooding, developmental stage, wheat type and variety. Therefore as a factorial experiment in randomized complete design based on winter bread wheat cultivars (Pishtaz, Marvdasht, Shiraz, Zarin, Shahriar, C-81-4, Sardari, Agosta seed, FGS and Azar2) at sta...

The domestication of wheat in the Fertile Crescent 10,000 years ago led to a genetic bottleneck. Modern agriculture has further narrowed the genetic base by introducing extreme levels of uniformity on a vast spatial and temporal scale. This reduction in genetic complexity renders the crop vulnerable to new and emerging pests and pathogens. The wild relatives of wheat represent an important sour...

An integrated optimization model was developed for the spatial distribution of agricultural crops in order to efficiently utilize agricultural water and land resources simultaneously. The model is based on the spatial distribution of crop suitability, spatial distribution of population density, and agricultural land use data. Multi-source remote sensing data are combined with constraints of opt...

The conditional volatility in the daily spot prices of the crops traded on the South African Futures Exchange (yellow maize, white maize, wheat, sunflower seed and soybeans) is determined. The volatility in the prices of white maize, yellow maize and sunflower seed have been found to vary over time, suggesting the use of the GARCH approach in these cases. Using the GARCH approach, the condition...

in urmia county, irrigated wheat yield varies in different regions. the highest and lowest yields are attributed to nazloo region (6.58 tons per hectare) and the lowest yield was for silvana region ( 2.77 tons per hectare) respectively. so, the purpose of this study is analysis of management factors impact on irrigated wheat yield in nazloo and silvana regions of urmia county. to this end, by q...

ABSTRACT: Based on the goal of income increasing, this research uses DEA-BCC model under input and output orientation to estimate differences changes in technical efficiency wheat production by farmers different scales based survey data 1669 farmers’ from China’s main wheat-producing regions. Results showed that there are significant farmer’s optimal scale orientation. The relationship between ...
