Knowing the trees nutritional status is necessary for achieving balanced fertilization in orchards. One approach for determining the nutritional status of orchards is the compositional nutrient diagnosis method. In the present research this method was performed to evaluate the nutritional status of three important areas of lime cultivation in Hormozgan province, south of Iran, during 2014 and 2...
Translocation of radioactive carbon from the fed part of a blade to the rest of the plant was impaired by a deficiency in phosphorus only when the level of phosphorus was low enough to decrease growth.Phosphorus deficiency decreased the percentage of inorganic phosphorus more than that of organic phosphorus, indicating little effect of phosphorus deficiency upon phosphorylation.Thus phosphorus ...
Leaf size indices of the tree species in the peatland of Agusan del Sur in Mindanao in Philippines was examined to deduce the variation of forest structure and observed forest zonation. Using raunkiaer and webb’s leaf size classification, the leaf morphometrics of seven tree species consistently found on the established sampling plots were determined. The species includes Ternstroemia phi...
the co-inoculation of mulberry with phosphate solubilizing micro-organisms, nitrogen fixing bacteria and arbuscular mycorrhiza has influenced its macronutrient uptake through leaf. the data revealed that maximum nitrogen (484.12 kg /ha) , phosphorus (59.83 kg /ha) and potassium (244.61 kg/ha) uptake through leaf has taken place due to co-inoculation treatments as compared to the un inoculated t...
Thirty-six daily duplicate diet samples were collected from 12 healthy female Japanese vegans and sodium, potassium, calcium, magnesium, phosphorus, iron, zinc, copper, manganese, iodine, selenium, chromium and molybdenum in the diets were measured to estimate mineral and trace element intake by Japanese vegans. Significantly higher intake of potassium, magnesium, phosphorus, iron, copper, mang...
Magnesium tolerance tests were conducted in five female goats to determine the effect of increasing dietary potassium level from .9% (basal diet) to 4.0% (high-K diet) on an animal's capacity for disposing of an intravenous load of magnesium. Both diets contained about .07% magnesium, .91% calcium and .56% phosphorus. Following intravenous injections of magnesium acetate (.5 mEq of Mg/kg body w...
Background and objectives: One of the basic demands in rangeland studies for its proper management is to investigate and understand how the spatial distribution of vegetation and effective factors in this regard. Knowing the behavior of plant species in relation to ecological factors, especially soil factors, is an effective guide in the improvement programs and proper use of pastures. The pres...
wheat (triticum aestivum l.) was grown in earthen pots containing soil of balkasar soil series (sandy loam) in green house at the department of soil science and swc, pir mehr ali shah arid agriculture university, rawalpindi during rabi season, 2007. the crop was treated with two levels of phosphorus (40 and 80 kg p ha-1 ) in the form of ssp, tsp, np and dap. a basal doze of 100 kg n and 60 kg k...
The present study was conducted in order to investigate the effects of silicon and salinity on growth, chemical composition and physiological properties of rice var. Hashemi, in the greenhouse of agricultural college of University of Tabriz during 2011. It was arranged as factorial based on a completely randomized design with three factors consisting of silicon at four levels (control, 100, 200...
In order to study the effect of bacterial growth on water use efficiency of alfalfa, a greenhouse experiment, as factorial based on completely randomized blocks design with three replications, was conducted at Faculty of Agriculture, University of Mohaghegh Ardabili, Ardabil, Iran, in 2012. Treatments consisted of 3 levels of water stress (75, 55 and 35% of field capacity) and seed inoculation ...
