In order to investigate P acquisition efficiency (PACE) and P utilization efficiency (PUTE) of the corn in the presence of phosphate-solubilizing microorganisms (PSMs), a factorial experiment was carried out in a completely randomized design in the greenhouse. The factors were including P sources (tricalcium phosphate (TCP) and rock phosphate (RP)) and microbial inoculation (control, soluble P ...

In this study, rapeseed Okapi cultivar was treated under three NaCl levels (0, 50 and 100 mM) and four Zinc oxide nanoparticles (ZnO NPs) concentrations (0, 20, 40 and 80 mgL-1) at flowering stage. The experiment was performed in a completely randomized design (CRD) in the greenhouse of Biology Department of Urmia University, in 2015. Results showed that NaCl (100 mM) significantly enhanced tot...

In this study, impacts of different element absence (nitrogen, sulfur, phosphorus and magnesium) and supplementation (nitrogen and zinc) on element uptake and triacylglycerol production was followed in wild type Chlamydomonas reinhardtii CC-124 strain. Macro- and microelement composition of C. reinhardtii greatly differed under element regimes studied. In particular, heavy metal quotas of the m...

Abstract Many agricultural researches have been performed to improve soil productivity. Nitrogen (N) and Phosphorus (P) are essential elements which are utilized by the plants in large amounts. Phosphorus can be provided by applying chemical fertilizers. Microorganisms convert insoluble phosphate to the soluble form and some bacteria such as rhizobacteria play an important role in this proces...

Twentyfour surface soil samples (0-30 cm) collected from salt affected area of Vasantdada Sugarcane Research and Development farm Manjari(Bkk.), Pune, Maharashtra (India) were studied for the Cu, Zn, Fe and Mn status in relation to important soil factors. All the soil samples had adequate amount of Cu, Zn, Fe and Mn. Iron and Maganese are significantly positively correlated with organic carbon,...

Micronutrients availability including that of Zn is critical for optimum growth of plants. Zinc availability in calcareous soils of Iran is relatively low due to the presence of a large amount of CaCO3 and high pH levels. Overapplication of phosphorus to soils may also cause P-induced Zn deficiency. The objective of this experiment was to evaluate the effect of phosphorus and zinc application o...

This research was aimed at investigating the effects of foliar application of calcium silicate and sodium silicate on growth and biochemical characteristics and leaf elements of chrysanthemum. This study was conducted as a factorial with completely randomized design and silica source at two levels (calcium silicate and sodium silicate) and concentration of silica at five levels (0 (control), 50...

Among abiotic stresses, soil and water salinity are the major factors affecting agricultural crops growth and productivity worldwide. On the other hand, the scion-rootstock combination and also foliar application of chimical compounds as salicylic acid can affect the nutrient elements content of almond leaf under salinity conditions. Therefore, in this study, the effects of foliar application o...
