iron is an essential microelement for plant growth. low content of organic matter and excess application of phosphate fertilizer in soils can be affected on availability of iron. in this study the effect of iron, phosphorus and organic matter on growth and iron uptake of mays was evaluated. a greenhouse experiment was conducted with two levels of cattle manure (0 and 1 %), three levels of phosp...

Tridentate chelate ligands of 2,6-bis[hydroxy(methyl)amino]-1,3,5-triazine family rapidly release iron from human recombinant ferritin in the presence of oxygen. The reaction is inhibited by superoxide dismutase, catalase, mannitol and urea. Suggested reaction mechanism involves reduction of the ferritin iron core by superoxide anion, diffusion of iron(II) cations outside the ferritin shell, an...

in order to study the effects of foliar application of naa and plant thinning on growth, yield and fruit quality of melon genotype khatooni, the experiment was conducted in a randomized complete block design with three replications at research field of faculty of agriculture, university of zanjan. treatments consisted of foliar application of naa at three levels (25, 50 and 100 mg.l-1 at 4-6 tr...

a field experiment involving red clover varieties k-39, k-17, una and viola was established on an acidic (phh2o 4.8) soil to evaluate the effects of foliar application of cobalt (a beneficial nutrient for efficient nitrogen fixation) on seed yield, and on seed yield components. the foliar spray of the crop was carried out using cobalt nitrate [co(no3)2] with the treatments: one application at t...

Iron (Fe) and manganese (Mn) are essential nutrients for plants. Application of high levels of either Fe or Mn is often accompanied by relatively low levels of uptake for the other nutrient. The antagonistic relationship of these nutrient elements may occur either during absorption by roots or during translocation from roots to shoot. A greenhouse study was carried out to study the effect of so...

The two-location field experiment was conducted to study the possible alleviation of droughtstress effects on red bean by ultrasonication and 24-epi-brassinolid. Locations were AgriculturalResearch Center in Shahrood, Iran and the other in bean farm, 40 km off Shahrood city in 2015.Experiment factors included irrigation of main plots at three levels of normal irrigation (60 mmevaporation from e...

to investigate the effect of deficit irrigation and macro and micro fertilizers on morpho-physiological characteristics of satureja a field experiment was conducted in agricultural research station of haji-abad (hormozghan province-iran) a split plot randomized complete block design with three replications during the growing season of 2012-2014. irrigation treatments consisted of normal, modera...
