A number of economic and environmental benefits are associated with the use of no-till in production agriculture in the United States. There are lower labor, energy, and machinery costs associated with no-till farming relative to conventional tillage systems and other types of conservation tillage. Reduced erosion and runoff associated with no-till also lead to a number of environmental benefit...

The Inland Pacific Northwest (IPNW) encompasses 1. 6 million cropland hectares and is a major wheat-producing area in the western United States. The climate throughout the region is semi-arid, making the availability of water a significant challenge for IPNW agriculture. Much attention has been given to uncovering the effects of water stress on the physiology of wheat and the dynamics of its so...

The aim of the study was to document wheat landraces that were and and Dandi districts, West Shewa, Ethiopia; and to investigate the extent of genetic loss and its causes. Survey was carried out in three Peasant Associations of Ambo District and four Peasant Associations of Dandi District from 2007 to 2008. Three to five farmers’ group per Peasant Association containing 5 to 12 individual farme...

The process of informal seed production and distribution was started recently only two years ago in the study area. As wheat is the most important crop grown in rain fed pothwar area of Punjab Province, so adoption of improved technology has significant affect on the livelihood of the farmers. In the present study, paired t-test methodology has been used for varietals analysis, as two years are...

Selection of genotypes based on high value of heritability and forecasted genetic conditions would be an effective method for improvement of wheat cultivars. The present investigation was carried out to estimate the genetic variability of agro-physiological characters using biometrical genetic techniques in 20 bread wheat genotypes under irrigated condition. For this purpose an experiment was c...

Agriculture is the origin of existence and survival in any society. However, this sector always associated with risk uncertainty, farmers are faced many challenges. Therefore, main aim research was to explore (production) factors irrigated wheat production systems among Kermanshah province, Iran. The exploratory nature study on one hand need for expert judgment other necessitated a Delphi desig...

Land-use and agricultural practices affect the soil microbial carbon (C) and nitrogen (N) turnover and hence the biosphere-atmosphere exchange of greenhouse gasses (GHG), namely N2O, CH4 and CO2. In view of the global importance of irrigated agriculture, it is crucial to understand how and to which extent this land-use system interferes with the terrestrial N and C cycles and contributes to the...

We hypothesize that institutions such as agricultural cooperatives influence regional levels of variety diversity through input supply, processing or marketing functions. This diversity can also affect yield, a partial measure of crop productivity. We test these hypotheses with data from southern Italy, a mega-diversity spot and centre of diversity for durum wheat. Cooperatives in the southern ...
