The lead (Pb)/zinc (Zn) tailings contained high concentrations of heavy metals (total Pb, Zn, Cu and Cd concentrations 4164, 4377, 35 and 32 mg kg(-1), respectively), and low contents of major nutrient elements (N, P, and K) and organic matter. A field trial was conducted to compare growth performance, metal accumulation of Vetiver (Vetiveria zizanioides) and two legume species (Sesbania rostra...

abstract- to evaluate effects of different soil moisture conditions namely, phosphorus (p) and zinc (zn) application, on extractable zn and fe, two experiments were conducted in laboratory conditions based on a completely randomized design with a factorial arrangement of treatments with two replications. the first experiment was performed with the following factors; incubation time at four leve...

Though rice is the predominant source of energy and micronutrients for more than half of the world population, it does not provide enough zinc (Zn) to match human nutritional requirements. Moreover, climate change, particularly rising atmospheric carbon dioxide concentration, reduces the grain Zn concentration. Therefore, rice biofortification has been recognized as a key target to increase the...

Th e response of diff erent fertilizer doses was studied on the ratoon crop as well as main crop. Th e diff erent fertilizer doses under the study were F1 (N=90, P2O5 = 45, K2O=50, S=13, Zn = 4: in kg ha-1), F2 (N=105, P2O5 = 55, K2O=60, S=13, Zn = 4: in kg ha-1), F3 (N=120, P2O5 = 65, K2O=70, S=13, Zn = 4: in kg ha-1), F 4(N =135, P2O5 =75, K2O=80, S=13, Zn=4: in kg ha-1) and F5 (N=150, P2O5 =...

Since the nutrient survey of the South African sugar industry in 1970 little use has been made of analytical data for determining trends in soil fertility and plant nutnent uptake in the regional extension areas of the industry. This became possible in 1980 following computerisation of fertilizer recommendations by the Fertilizer Advisory Service (FAS)of the Experiment Station. Since then a dat...

In order to study effect of phosphorus fertilizer and micronutrients foliar application on yield sorghum, a field experiment was conducted in at 2011 in Research Farm of Payame Noor University of Zahedan, Iran. This experiment was done as split plot Based on randomized complete block design with three replications. Experiment treatments included: micronutrients foliar application containing ele...

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...
