There is a growing need for developing high-throughput tools for crop phenotyping that would increase the rate of genetic improvement. In most cases, the indicators used for this purpose are related with canopy structure (often acquired with RGB cameras and multispectral sensors allowing the calculation of NDVI), but using approaches related with the crop physiology are rare. High-resolution hy...

agro-ecological zoning is one of the effective tools for assining land to suitable land use.the study areawith16618ha islocatedin abyek area inqazvin province. in totally 43 agro- ecoloical zones were distinguished by combining maps of isohyet, isotherm, length of growing periodand agro-edaphic zones. based on above information a land suitability was produced for the study area and prediction o...

in the vast rainfed regions, diminishing returns from the public irrigation systems, climate change induced chaotic fluctuations in the hydrologic regimes and a large demand-supply gap in non-cereal food items are all compelling reasons for the need to realise the production potential of rainfed farming areas. Little control over the rainfall and absence of suitable mechanisms for storing or co...

Blowing dust from excessively tilled fallow fields is a major soil loss and air quality concern in the low precipitation (<300 mm annual) wheat (Triticum aestivum L.) production region of the Inland Pacific Northwest (PNW) of the United States. A 2-year tillage-based winter wheat-summer fallow (WW-SF) rotation is practiced on >90% of rainfed cropland in the region. Earlier research proved the u...

Many sustainable agronomical practices can be adopted to contain environmental risks of crop production and, at the same time, sustain yield and quality. In this framework, the aim of this research was to study the effects of continuous cropping (CC) and crop rotation, tillage and fertilization strategies on durum wheat (Triticum durum Desf.) production. The responses of soil properties we...

Yields of dryland (rainfed) wheat in Australia have increased steadily over the past century despite rainfall being unchanged, indicating that the rainfall-use efficiency has increased. Analyses suggest that at least half of the increase in rainfall-use efficiency can be attributed to improved agronomic management. Various methods of analysing the factors influencing dryland yields and rainfall...

Blowing dust from excessively tilled fallow fields is a major soil loss and air quality concern in the low precipitation (<12 inches annually) wheat production region of the Inland Pacific Northwest (PNW). A 2-year, tillage-based winter wheatsummer fallow (WW-SF) rotation is practiced on more than 90% of rainfed cropland in the region. Earlier research proved that the undercutter method for non...

A total of 10 field experiments were carried out during the 1998 and 1999 growing seasons both in the north (Lleida) and the south (Granada and Jerez) of Spain. In Lleida and Granada, the experiments were conducted under both irrigated and rainfed conditions, while the Jerez trials were carried out only under rainfed conditions. Ten durum wheat genotypes were used in this study. Quality determi...
