background and objectives:due to increase in the world population and increasing concerns about the future food security, shrinking the yield gap has became a hot area of research in field crops. estimation the amount of yield gap and determination of it’s causes requires using proper methods. boundary line analysis is a statistical method that can quantify the response of yield to an environme...

(Abstract) Recent studies have provided conflicting results in regards to equine intradermal skin testing and its use in defining causative antigens in IgE mediated diseases such as equine recurrent airway obstruction (RAO). This study was divided into two experiments. In the first experiment of this study, the hypothesis tested was normal horses would have minimal variability in the wheals for...

In order to study of the effect of seed inoculation with PGPR on nitrogen and phosphorus use efficiency of spring wheat in different levels of nitrogen and phosphorus fertilizers, an experimental was conducted at the Research Farm of Mohageh Ardabili University, Ardabil, Iran during 2012 year. The combination of nitrogen fertilizer in three levels (0, 40 and 80 kg N/ha as urea) and phosphorus f...

Agroindustrial by-products hold an enormous potential to be bioconverted into high-value-added products such as polyhydroxyalkanoates (PHA), a cost-effective alternative conventional plastics. In this study, cheese whey, highly abundant side stream of the making process, was explored feasible substrate for selection mixed culture enriched in PHA-storing bacteria using sequencing batch reactor u...

We investigated the effects of dietary supplementation of zinc (ZnO; 0, 40, 80, 120 and 160 mg/kg) and Vit E (α-tocopheryl acetate; 0 and 40 IU/kg) on egg production, egg quality and Zn content of egg fractions and tissues in Japanese quails. Using a 5 × 2 factorial design, a total of 960 Japanese quails (Coturnix coturnix japonica) at day 70 of age were housed in cages and randomly assigned in...

An experiment was conducted on “Response of inorganic fertilizers, wheat residue and rhizobium soil health yield attributes Green gram (Vigna radiata L.) var. Samrat” at research farm Soil Science Agricultural Chemistry, design laid out in randomized block (RBD) with three replications. taken for study recommended doses fertilizers (N, P2O5 K2O @ 20, 40 20 kg ha-1) applied rhizobium. The variet...
