Approach: The experiment included nine treatments with 10 birds in each replicate using a 3×3 factorial design for two main factors of citric acid (0, 3 and 6%) and three phytase enzyme (0, 500 and 1000 IU kg −1). The diets were formulated based upon corn-soybean meal 7 to 21 and 22 to 42 day periods. Results: Using different levels of citric acid in diets had no effect on internal organs (except relative heart weight), whereas, diets containing 6% citric acid decreased feed intake, body weight gain and carcass yield (p<0.05) and improved feed conversion ratio and organs relative weight. Also, microbial phytase caused increase in feed intake, weight gain and relative neck weight (p<0.05). Conclusion: Depression of performance was differently affected by citric acid levels. Also, there was an additive effect between microbial phytase and citric acid.

Treatments were two canola (Brassica napus L.) cultivars, Gabriela and Elvis, and two levels of monopotassium phosphate (0 and 80 mg P kg–1). The results showed that P fractions were changed in the 0–3 mm layer from the rhizoplane. The concentration of Olsen P was reduced in the soils of two cultivars, but water-soluble P (WSP) was increased in the upper box of the rhizobox, compared to the unplanted soil. The Olsen P and WSP fractions in the lower box were increased with increasing the distance from the root surface. Under P deficiency condition, di calcium phosphate (DCP) was 3.96, 4.38, and 6.25 mg kg–1 for Gabriela, Elvis, and unplanted soil, respectively. The results also showed that Gabriela prefers calcium phosphates and Elvis prefers Fe–P form. Shifting of DCP to Fe–P in the upper box and shifting of DCP to Al–P and Fe–P in the lower box can be considered as a useful index for management of soil P. In other words, observing of this shifting pattern shows the better time for P fertilization. So, studying the chemical forms of phosphorus may be used as an efficient tool for P recommendation in canola cropping systems.

The objective of this study was to assess the effect of AMF symbiosis on plant growth, physiology, and nutrients accumulation in leaves and roots of Ailanthus altissima (Mill.) Swingle under Cd and saline conditions. The pot experiment was carried out in factorial based on randomized complete block design (RCBD) with three replications. The treatments included salinity at three levels (non-saline water, 4 ds/m, and 8 ds/m), inoculation with AMF at two levels (uninoculation and Glomus mosseae inoculation) and cadmium (Cd) pollution at three levels (unpolluted soil, 15 mg Cd/kg soil, and 30 mg Cd/kg soil). The results revealed salinity and Cd pollution decreased plant height shoot and root biomass, but AMF increased them. The highest plant height, shoot and root biomass were observed at unpolluted and non-saline water. In contrast, the lowest plant growth was in uninoculated treatments with high salinity and Cd levels. Salinity increased proline content, CAT and SOD activities. Cd pollution did not change the proline concentration in the plants. The highest proline concentration and antioxidant enzyme (SOD and CAT) activities were observed in uninoculated plants with simultaneous application of high Cd and salt levels. Na+ accumulation in roots and leaves increased with salinity, but AMF decreased it. K+ content in leaves and roots decreased with Cd pollution and salinity and AMF increased it. Salinity and Cd pollution significantly accumulated high Cd in roots and leaves. Our work will widely improve the current knowledge of salinity and Cd tolerance mechanisms in tree species.

So deficiency and toxicity of them causes growth inhibition in most plant. The aim of this study was to investigate the effect of different concentrations of Cu and Zn on morphological traits, essential oil content and the determination of these elements in during the process of steam distillation. This experiment was conducted as factorial based on complete randomized design with three replications in greenhouse conditions. The treatments consisted of three levels of Copper (0, 5 and 25 mg.kg-1 CuSO4) and zinc (0, 10 and 50 mg.kg-1 ZnSO4) and their combination. Results showed that interaction of Cu and Zn on the fresh weight of root and chlorophyll (p≤ 0.05), dry weight of roots, concentration of Cu and Zn on the shoots, residual distillation water and material (p≤ 0.01). With increasing Cu and Zn in soil, concentrations of them increased in shoots. Concentration of Cu and Zn in the sum of residual distillation water and material were similar the concentration of metals in shoots plant before distillation. Negative interaction between Cu and Zn occurred at higher application, therefore should consider combining these two elements not done at high levels. Retention of cu and Zn in the sum of residual distillation material and water, asset cannot transmit the elements into essential oil and cultivation of these medicinal plants in contaminated soils with Cu and Zn.

A uniform precision type central-composite design consisting of three variables (LM pectin, calcium, aspartame), in a three-level pattern with 20 runs (with six center point), was prepared. Results showed that overall acceptability was affected mostly by changes in LM pectin level (P<0.05), while it was not affected significantly by change in calcium and aspartame levels. The factor levels for the formulation that maximized acceptability were as follows: aspartame = 0.104%, pectin = 1.091% and calcium = 0.015%.

A two factor central composite design was employed to optimize the jam in order to obtain a product with adequate sensory properties, especially, overall acceptability. The independent variables were the pectin and calcium concentrations at 5 different levels. All formulations were submitted to 10 semi-trained assessors using a 7-point structured hedonic scale. The highest score for overall acceptability (6.08) was achieved with a jam containing 1.185% pectin and 0.015% of calcium
