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 ...

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...

I apologize for making some of you nervous, and perhaps even resentful, but I HAVE HAD ENOUGH! I do not like the new unethical face of my profession, where incessant seeking of more money has replaced service to the public, honesty, and self-respect. Numerous areas of major ethical concern in dentistry are identified in this article. The ongoing, if not accelerating, degeneration of professiona...

The study examines the changes in climatic elements and agronomic parameter (maize hectarage and output) for maize production in different ecological zones of Nigeria from 1980 2002. The study also evaluated the degree of variability in these parameters. To achieve these objectives, secondary data on climatic elements and agronomic parameters for 22years were analysed using two – way Analysis o...

extended abstract introduction rainfall prediction at regional and global scales is mostly as principle component of hydro-meteorological studies in un-gauged regions. ground-based measurements of precipitation are available with high accuracy in synoptic stations. spatial distribution of operational stations is now as one of the biggest problems in the developing countries such as iran, which ...
