in order to evaluate effects of iron, zinc and manganese, and the methods of applying them on yield and yield components of sweet corn (zea mays saccharata), an experiment was performed as factorial based on randomized complete block design with four replications at the research farm of urmia university. experimental factors were micronutrient fertilizers with four levels (control, iron, zinc a...

The results of field studies the use biological products and microfertilizers in cultivation corn for grain sunflower production conditions Krasnodar Region are presented. Indicators a comparative assessment economic new schemes application fertilizers plant protection from point view agrotechnical efficiency given.

Background: Zinc deficiency is a common problem in the world. Finding adequate solution for combating this problem is very important. The aim of this research was study of the effect of consumption of whole bread baked from cultivated wheat with microfertilizer on serum zinc. Materials & Methods: This double blind field trial was carried out on two villages: Tajaragh as experimental (n=160) an...

The purpose of the research is to obtain micronutrient fertilizers by applying salts and their complex forms phosphorus obtained in incomplete standards nitric acid or salt mixtures. Central Kyzylkum phosphorites (low-grade P 2 O 5 -12.38%, CaO-43.68%, CO -13.48%, non-enriched -16.38%, CaO-45.93%, -18, 15%, SO 3 -1.86%, thermoconcentrate -27.40%; CaO-54.68%; - 4.52%) were decomposed with at dif...

Wheat is an important source of minerals such as iron, zinc, copper and magnesium in the UK diet. The dietary intake of these nutrients has fallen in recent years because of a combination of reduced energy requirements associated with sedentary lifestyles and changes in dietary patterns associated with lower micronutrient density in the diet. Recent publications using data from food composition...

Rice (Oryza sativa L.) is the most important food crop not only in Asia but also entire world. Over past several decades, conventional fertilizer application for rice has caused loss of nutrients, which could lead to a series environmental problems such as eutrophication and greenhouse effects. The emergence slow controlled-release fertilizers provides new option more efficient fertilization ri...

Polymer-coated controlled-release fertilizers (PCFs) are the most widely used fertilizers in the production of container-grown nursery plants. The duration and magnitude of PCF nutrient release varies with product and this variation can significantly affect plant growth. Three experiments were conducted to determine the long-term nutrient release patterns of three PCFs (each with a rated longev...

Chromium is commonly present in the surroundings as a result of its natural occurrence, human activities from industries and agriculture [1]. Most industrial processes produce metals as byproduct in the ecosystem, and these may end-up in tissues of bird species existing in such natural ecosystems [2]. In most cases, the concentration may be higher than the permissible limit in avian species. Ch...
