Two field experiments were conducted to evaluate the effects of phosphorus level and humic acid on pea (Pisum sativum L.) yield quantity and quality, under drip irrigation system, during 2011 and 2012 seasons. Experiments were carried out in the Research and Production Station, National Research Centre, El-Nobaria Site, Beheara Governorate, Delta Egypt. Phosphorus fertilizer was applied at rate...

Two field experiments were conducted to evaluate the effects of phosphorus level and Agrosol treatment on pea (Pisum sativum L.) yield quantity and quality, under drip irrigation system, during 2012 and 2013 seasons. Experiments were carried out in the Research and Production Station, National Research Centre, El-Nobaria Site, Beheara Governorate, Delta Egypt. Phosphorus fertilizer was applied ...

This study investigated the effects of a combination of calcium and magnesium carbonate intestinal phosphate binders, associated with natural reno-protectant substances (the uraemic toxin binder chitosan, vasoactive peptides and an extract of Astragalus membranaceus) (Pronefra®, Virbac, France) on blood parameters and mineral balance in cats. Ten cats, 2 to 5 years old at day 0, were given the ...

We evaluated the effect of phosphorus application rates from various sources and in the presence or absence of filter cake on soil phosphorus, plant phosphorus, changes in acid phosphatase activity, and sugarcane productivity grown in Eutrophic Red Ultisol. Three P sources were used (triple superphosphate, Araxa rock phosphate, and Bayovar rock phosphate) and four application rates (0, 90, 180,...

background: exogenous phytase enhances the utilization of plant phytate phosphorus in poultry. objectives: in the present study the effects of exogenous phytase was investigated on tibia bone characteristics of white quail. methods: in a 2x2 factorial arrangement, eighty, 11-day old unsexed chicks were randomly divided into 4 treatments of 20 replicates. all birds received one of four experimen...

ruminal bacteria and protozoa provide excellent organic phosphorus (p) sources for the host animal. this experiment was conducted to compare the bioavailability of bacterial and protozoal p in comparison with that of dicalcium phosphate (dcp) as a reference phosphorus source. bacteria and protozoa were isolated from the rumen contents of dairy cows and the chick-model was used to determine the ...

in order to investigate the effect of various rates of phosphorus fertilizer and efficiency amount of broadcasting and banding methods on yield and yield components of corn (zea mays l.), a field experiment were arranged in a split-plot design based on a randomized complete block design with four replications at the research field, ramin agricultural and natural resources university, mollathani...

Bioaccumulation of potentially toxic metals by litter-feeding invertebrates is determined not only by the concentration of metal in the diet, but also by the flux of food through the body. Nitrogen and phosphorus are the main elements regulating food consumption and so are expected to affect the bioaccumulation of trace elements such as cadmium. To test this idea, we applied a three-factor orth...
