New irrigation methods under different nutritional element supplies for maize production was designed and tested for evaluate quantitative and qualitative parameters by split-plot arrangement according complete randomized block design with three replications. Different Irrigation regimes was belonged to main plots (Conventional furrow irrigation: CFI or A1, Alternate furrow irrigation: AFI or A...

BACKGROUND: Wheat produces more than 50 percent of requirements protein and calorie for human nutrition in Iran. Management of nitrogen fertilizing is important to increasing wheat production. So, among chemical fertilizer a high correlation reported between nitrogen and yield. Also to improve physical, chemical and biological properties of soil, organic fertilizer such as verm...

Seed composition in soybean [Glycine max (L) Merr.] has not been well investigated under charcoal rot infestation under irrigated and non-irrigated conditions. The objective of the present experiment was to assess seed composition and nitrogen fixation under these conditions. No significant differences in protein levels in the moderately resistant germplasm line DT97-4290 were observed under th...

A simple method based on atomic absorption spectrophotometry and using protein concentration as the reference standard was used for measuring the total tissue iron concentration in needle liver biopsy specimens from 47 patients with varying levels of body iron stores. The values obtained showed a close correlation over a wide range with measurements of total chelatable body iron stores. A compa...

in this study, a mixed matrix polyethersulfone/iron-nickel oxide nanoparticle nanofiltration membrane was prepared by the solution casting technique. polyvinylpyrrolidone was also used as a membrane pore former in membrane fabrication. the effect of iron-nickel oxide nanoparticles concentration in the casting solution on the membrane structure and performance was investigated. scanning optical ...

Iron deficiency is a nutritional problem in plants and reduces crop productivity, quality and yield. With the goal of improving the iron (Fe) storage properties of plants, we have investigated the function of three Arabidopsis proteins with homology to Vacuolar Iron Transporter1 (AtVIT1). Heterologous expression of Vacuolar Iron Transporter-Like1 (AtVTL1; At1g21140), AtVTL2 (At1g76800) or AtVTL...

iron is an essential nutrients in rice. accurate assessment of this element in paddy soils is very important. improving fertility management, accurate interpolation, being aware of spatial variability and patterns of distribution of micronutrients are the most important factors in soil management and accurate consumption of fertilizers. this study was done for investigating of available iron, d...
