zinc (zn) and copper (cu) are essential elements and increased plant growth in low concentrations. while high concentrations of these elements as a limiting factor, can cause adverse symptoms on the plants. in the present study, the uptake of micronutrient and macronutrient by pennyroyal were studied in a zn and cu deficiency and toxicity in soil. three levels of copper (0, 5 and 25 mg/kg) and ...

Pearl millet is a multipurpose grain/fodder crop of the semi-arid tropics, feeding many of the world's poorest and most undernourished people. Genetic variation among adapted pearl millet inbreds and hybrids suggests it will be possible to improve grain micronutrient concentrations by selective breeding. Using 305 loci, a linkage map was constructed to map QTLs for grain iron [Fe] and zinc [Zn]...

introduction half of the world's population suffers from micronutrients malnutrition. use of bio-fertilizers in sustainable agricultural systems is important in production and enables plants to absorb more water from soil and improves plant nutrient uptake and photosynthesis. benefits of vermicompost application in agriculture is due to its content of organic matter, plant nutrients and plant g...

background and purpose: the heavy metal pollution and its fractionations in the surface sediments of darreh-morad beyg river, hamedan city were monitored for cd, cr, cu, fe, ni, pb, and zn in 2014.   materials and methods: totally 30 surface sediment samples were taken from 10 stations with three replicates. the samples subjected to bulk digestion and chemical partitioning. the concentrations o...

An in vitro dialysis method was employed to determine the effect on the Fe and Zn absorption of the type (beef, pork and soyabean) and the amount (10 and 30 g/kg) of protein present. In addition, the effects of low- and high-molecular-weight (LMW and HMW respectively) digestion products were investigated. After in vitro digestion and dialysis a lower percentage of N, Fe and Zn was found in the ...

Responses in micro-mineral metabolism to changes in dietary ingredient composition and inclusion of a micro-mineral premix (Fe, Cu, Mn, Zn and Se) were studied in rainbow trout. In a 2 x 2 factorial design, triplicate groups of rainbow trout (initial weight: 20 g) were fed over 12 weeks at 17°C a fishmeal-based diet (M) or a plant-ingredient based diet (V), with or without inclusion of a minera...

Background: Unsafe food consumption is a severe problem because of heavy metal contamination, which is caused by director indirect activities of industries. The present study was conducted to assess the risk of human health by Heavy metals (Cu, Co, Fe, Zn and Mn) through the intake of vegetables and fishes obtained from the area adjacent to the Hazaribag tannery campus, Dhaka, Bangladesh. Resul...

Zinc, sodium, potassium, copper and iron concentrations were analysed in serum and tissues of guinea-pigs fed on a diet containing 1.25 mg Zn/kg diet over a period of 60 d. The response of the Zn-deficient (ZnD) animals to Zn supplementation (100 mg Zn/kg diet) was also studied for 15 d. Serum studies in the ZnD group revealed significant decreases in the concentrations of Zn and Na from 24 d, ...

Foliar spraying of a small amount of micronutrients (iron and zinc) may increase the yield of anise(Pimpinella anisum L.), an anethole-rich important medicinal plant. In order to evaluate the effect of iron (Fe) and zinc (Zn) spraying (0, 2, 4, and 6 g l-1) on the nutrient contents and the essential oils of anise, a factorial experiment was conducted based on a randomized complete block design ...
