Sugar beet is one of the most important agricultural crops and its yield depends on irrigation water. Due to the impossibility of assessing the effect of all water amount strategies on sugar beet yield, it is necessary to use crop models such as WOFOST, AquaCrop and Cropsyst. In order to achieve this goal, a set of data collected from Shahrekord’s Agricultural Research Station were used. Treatm...

To investigate the effect of cover crops on soil physical properties, weed control and yield of white radish, a filed experiment was carried out using randomized complete block design with three replications in 2017 and 2018 in the research field of Mohaghegh Ardabili University, Ardabil, Iran. Experimental treatments included: cultivation of barley (Hordeum vulgare L.) and hairy vetch (Vicia v...

The ever-increasing problem of water scarcity in arid and semi-arid regions of Iran has necessitated the demand to replacement of sugar beet plantation by more water-use efficient plants. Sweet sorghum is one of the sugars plants with low water requirements that potentiates cost-effective sugar production in different regions. However, physiological aspects of sugar yield in this plant is not c...

Unsuitable planting and weed competition are the most important factors that greatly reduce the yield of bean. In order to study the effect of planting date on yield and yield components of three white bean cultivars in weed infest and weed free condition a factorial experiment with randomized complete block design and three replications was carried out at Semirom in 2009. The treatments were p...
