in order to investigate the effect of rhizobium bacteria, mycorrhiza fungi and foliar application of urea on qualitative and quantitative traits of soybean an experiment was conducted based on randomized complete block design with four replications. the experiment included six treatments as: control (c), rhizobium bacteria (r), rhizobium bacteria + mycorrhiza fungi (r+m), rhizobium bacteria + f...

Micronutriens deficiency is prevalent in case of drought stress conditions, so complementary boron and zinc nutrition are important for crops to overcome drought stress. This study evaluated the effect of zinc and boron foliar application on physiological traits of sesame under different irrigation levels. The experiment was conducted as a split plot in a randomized complete block design with t...

The continuous use of copper-based fungicide over the years in the control of black pod disease has led to heavy-metal accumulation in cocoa soils due to its non biodegradable nature. Considering the limited, available forest, it is therefore, necessary for the existing heavy-metal contaminated cocoa soils to undergo soil remediation in order to reduce the bioavailability of metals for plant up...

Mutualistic interactions with fungal endophytes and dinitrogen-fixing bacteria are known to exert key biological influences on the host plant. The influence of a fungal endophyte alkaloid on the toxicity of a plant has been documented in Oxytropis sericea. Oxytropis sericea is a perennial legume responsible for livestock poisoning in western North America. Livestock poisoning is attributed to t...

a split plot experiment based on randomized complete block design (rcbd) with three replications was conducted in 2012,treatments were included the time of foliar application with 3 levels (tillering stage, heading stage and no spray (control)) as main factor and cultivars in 4 levels (sardari, rijav, biseton and rashid) as the second factor. plant characteristics such as plant height, length o...
