To evaluate the effects of biofertilizers on some physiological growth indices of a soybean cultivar (M9) under water stress condition, a study was carried out in a split plot randomized complete block design in three replications at research station of Bu Ali Sina University, Hamedan, Iran in 2012. The main plots consisted of three levels of irrigation after 50, 100 and 150 mm evaporation from...

In order to study the effects of foliar application of potassium (K) and boron (B) and dificit irrigation treatments on quantitative and qualitative traits of sugar beet (Beta vulgaris L.), a split plot experiment was conducted based on randomized complete block design with three replications in the Research Field of Shahrekord University, Shahrekord, Iran, in 2019. The main plots were allocate...

Increasing soil contamination by chemicals has become an issue of increasing environmental concern. Leaching of chemicals into and through the vadose zone creats serious problems due to the contamination of the soil matrix, soil solution and groundwater. Therefore, in order to study the effect of the preferential flow, macropores and organic matter on mobility and leaching of the metals such as...

Soybean (Glycine max L.) is considered as one of the major sources of oil and protein. In this study, the effects of vermicompost (VC) and sulfur (S) on soybean photosynthesis responses, yield, and grain quality were studied. To this end, a split-plot design field experiment based on randomized complete blocks with nine treatments and three replications was conducted in Aligudarz city Lorestan ...
