One way to increase crop yield per unit of area is to close the gap between actual and potential yield in cropping systems. This study was conducted to determine the factors that affeced wheat yield gap in Khorramshahr, Iran during 2018-2019 growing season. In this study 60 fields of different areas under cultivation, field management practices and grain yield yield levels were surveyed based o...
almost half of agricultural lands in iran are saline and it is one of the most important constraints in cultivated lands. wheat is the most important crop in saline lands in rotation of golestan province. since saline soils amelioration is so expensive, achievement of genotypes with tolerant and high yield potential is essential. 22 genotypes of selective wheat of recent experiments with three ...
In order to study the genetic control of root yield, sugar yield and white sugar yield in tropical beet, the biplot of diallel data was used. 36 hybrids derived from crosses among 9 sugar beet genotypes along with four control treatments were evaluated at Safiabad Agricultural Research Center, Dezful, Iran during 2008-2009 growing season. The experimental design was a triple lattice design with...
Yield prediction before harvesting is one of the tools in order to planning food production supply in future.Yield prediction was carried out for Wheat(Triticum aestivum) using different meteorological variables with agrometeorological indices in Hamedan district during 2003-04 and 2004-05. According to correlation coefficients, standard error of estimate as well as relative deviation of predic...
sowing date is an important determinant of yield in canola. cultivation of winter rapeseed cultivars in semi arid regions of iran however it has high potential for production, but, mentioned cultivars are late maturity and this late maturity cause to that silique formation and seed filling periods mature in the same time with hot and dry weather condition. in contrast, spring rapeseed cultivars...
