in order to determine the best index for evaluating maize genotypes, 15 maize inbred lines were evaluated in two planting dates, 6 july to coincide heat stress with pollination time and 27 july as normal planting to avoid high temperature during pollination and grain filling period, using a randomized complete block design with three replications, in shushtar city, in 2007. result showed that i...

Improving winter wheat water use efficiency in the North China Plain (NCP), China is essential in light of current irrigation water shortages. In this study, the AquaCrop model was used to calibrate, and validate winter wheat crop performance under various planting dates and irrigation application rates. All experiments were conducted at the Xiaotangshan experimental site in Beijing, China, dur...

BACKGROUND Enhanced atrazine degradation has been observed in agricultural soils from around the globe. Soils exhibiting enhanced atrazine degradation may be cross-adapted with other s-triazine herbicides, thereby reducing their control of sensitive weed species. The aims of this study were (1) to determine the field persistence of simazine in atrazine-adapted and non-adapted soils, (2) to comp...

A suitable planting pattern and irrigation strategy are essential for optimizing winter wheat yield and water use efficiency (WUE). The study aimed to evaluate the impact of planting pattern and irrigation frequency on grain yield and WUE of winter wheat. During the 2013-2014 and 2014-2015 winter wheat growing seasons in the North China Plain, the effects of planting patterns and irrigation fre...

an increasing world population and the competitive nature of the stone fruit market, particularly nectarines [(prunus persica var. nectarine)], demand the selection of fruit with high quality attributes, flavor, and a wide range of maturity. information on this subject is limited at the present time. in search of superior nectarines, a trial was conducted to study growing degree days (gdd), ful...
