in order to agroecological zoning of current agricultural lands in golestan province for canola cultivation, geographic information system (gis) and analytical hierarchy process (ahp) were used to match the environmental requirements of crop and the land characteristics. the first, agroecological requirements of canola was identify from scientific resources then classified and needed thematic m...

geographic information system (gis) and analytical hierarchy process (ahp) were applied to ecological zoning of current agricultural lands in gorgan for sunflower cultivation. for this purpose, agro-ecological requirements of sunflower firstly, identified according to scientific resources. rating and thematic requirement maps were then provided. studied environmental-components were: average, m...

in this research, geographical information system (gis) and analytical hierarchy process (ahp) were applied to agricultural land use suitability of aq-qala township for barley cropping in rainfed condition. for this purpose, 17 environmental layers of the study area collected, and thematic maps such as slope, elevation, precipitation, average, minimum and maximum temperatures and some of micro ...

A comprehensive survey of the plant parasitic nematodes associated with cowpea (Vigna unguiculata) production fields was carried out in the three primary agro-climatic zones of Burkina Faso in West Africa. Across the three zones, a total of 109 samples were collected from the farms of 32 villages to provide a representative coverage of the cowpea production areas. Samples of rhizosphere soil an...

Saffron is grown in arid and semi-arid regions in Iran in late autumn, winter and late spring with rainy season. It should be irrigated by supplemental basin irrigation. Since rainfall is usually delayed in autumn, therefore, a pre-flowering irrigation of about 100 mm is needed. In areas with a seasonal rainfall of 600 mm a post- flowering irrigation of about 50 mm is adequate for economical yi...

This study examined the spatial and temporal rainfall variability from the 1940s to 2007 in the south west coastal region of Bangladesh. Time series statistical tests were applied to examine the spatial and temporal trends in three time segments (1948–1970, 1971–1990 and 1991–2007) and four seasons (Pre-monsoon; Monsoon; Post-Monsoon and Winter), during the period 1948–2007. Eight weather stati...

Under conditions of high vapor pressure deficit (VPD) and soil drying, restricting transpiration is an important avenue to gain efficiency in water use. The question we raise in this article is whether breeding for agro-ecological environments that differ for the rainfall have selected for traits that control plant water use. These are measured in pearl millet materials bred for zones varying i...

This study evaluated the accuracy of several models for estimating daily solar radiation (Q) across Australia. Data from 39 sites were taken from MetAccess. The sites were grouped into four climatic zones. Coefficients of nine models, including two newly developed formulae, were fitted for the 39 sites. Correlation coefficients (R2) between estimated Q and measured Q and root mean squared error...

accelerated soil erosion is an undesirable process that adversely affects water and soil resources. rainfall erosivity is an important factor in water erosion models. accordingly, the present study was conducted to estimate the rainfall erosivity throughout iran based on the latest available detailed rainfall data while considering its temporal and spatial variations. to accomplish this, th...
