A field experiment was conducted to evaluate the effect of planting pattern and irrigation system on antioxidant activity of wheat and Persian clover. The experiment was carried out as a two-factor factorial with three replications. The first factor was irrigation system (conventional and partial root-zone irrigation) and the second was planting pattern (sole wheat, sole Persian clover, alterna...

Experiment was conducted as split plot in a randomized complete block design with three replications in Kermanshah to shed lights on economic analysis of deficit irrigation and integrated application of biological and chemical fertilizer son cultivation of medicinal plant Borage (Borago officinalis L). Irrigation tritments include: a) 30% less water than crop requires invegetative, b) inreprodu...

In this paper, the effect of irrigation water salinity levels on seed germination, dry matter weight of seedlings at eight-leave stage, and the salt tolerance of 8 rapeseed cultivars was investigated. Relative yield reduction in saline and non saline conditions, salt sensitivity index and Van Genuchten-Hoffman methods were used to determine the salt tolerance of the cultivars. Results showed th...

Winter wheat is the most important crop in Germany, which why a three-year field trial (2015–2017) investigated effects of weather on biometric parameters relation to phenological growth stage winter varieties Opal, Kerubino, Edgar. In Brandenburg, there have been frequent extreme events phases that are relevant grain yields. Two were grown per year and parts experimental areas irrigated. addit...

In order to study the effects of supplementary irrigation and nano iron oxide on  the grain yield, and  some physiological and biochemical traits of wheat (Triticum aestivum L.) under rain fed conditions, a factorial experiment was conducted based on a  randomized complete block design with three replications in Agricultural Research Station of Ardabil, Northwest of Iran, in 2016. Factors inclu...

In north China, double cropping of winter wheat and summer maize is a widely adopted agricultural practice, and irrigation is required to obtain a high yield from winter wheat, which results in rapid aquifer depletion. In this experiment conducted in 2001-2002, 2002-2003, and 2004-2005, we studied the effects of irrigation regimes during specific winter wheat growing stage with winter wheat and...

In order to study the effects of supplementary irrigation and biofertilizers on grain yield, dry matter remobilization and some physiological traits of barley (Hordeum vulgare L.) under rainfed condition, a factorial experiment was conducted based on randomized complete block design with three replications at in 2017. Factors included irrigation at three levels (no irrigation as rainfed (I1), s...

Water stress is a frequent and critical limit to wheat (Triticum aestivum L.) production in North China. It has been shown that photosynthetic active radiation (PAR) is closely related to crop production. An experiment was conducted to investigate the effects of deficit irrigation and winter wheat varieties on the PAR capture ration, PAR utilization and grain yield. Field experiments involved J...
