development of new cultivars with high seed yield and desirable characteristics are major goals of lentil program for moderate and semi warm climate of iran. kimiya is a new lentil (lens cultivars medik) cultivar with high-yield, yield satability and adaptability to rainfed conditions. the iranian agricultural research, education and extension organization issued registration for kimiya on 9 au...

According to the IPI (integrated pollution index) report, almost 65 percent of all cities and dust of their roads were polluted with heavy metals. These areas threaten the health of human. Identifying, mapping and monitoring the pollution are the first step in contamination management. Hence, in recent decades many methods are presented to identify and mapping based on computer software that am...

katoul is a new soybeam cultivar originated from a genotype named d.p.x.3589 imported from the united states of american in 1990. this genotype was examined together with other soybean genotypes and check cultivars in different preliminary and advanced yield traits in gorgan and other research stations during 1999-2002. the mean seed yield of d.p.x.3589 in all these experiments was 3333 kgha-1 ...

within-field variation of wheat yield and spatial pattern of weed density and soil nitrogen were evaluated by geostatistical methods. samples were taken from a 90×120 m area located in a 3.8 ha wheat field. soil nitrogen content and weed density at tillering and wheat yield at maturity were measured in 1 m2 plots located at the center of 10×10 m grids. grain yield was varied between 1.5-4.9 t h...

Precipitation is important factor affecting vegetation and controlling key ecological processes. In order to quantify spatial patterns of precipitation in Chongqing tobacco planting region, China, under ArcGIS platform, three multivariate geostatistical methods including cokriging, small grid and regression kriging, coupled with auxiliary topographic factors extracted from a 1:100000 DEM were a...
