This research was carried out as pod cultivation to evaluate effect of different level of zinc and cadmium on agro physiological traits of Maize via factorial experiment based on completelly randomized design with three replications along 2012-2013. The factors included different level of Zinc (Zn1=0 or Control, Zn2=15 and Zn3=30 mg.kg-1) and Cadmium (Cd1=0 or control, Cd2=10, Cd3=20 and Cd4=30...

introduction: use of unbalanced chemical fertilizers especially p, having low absorption efficiency and low solubility compounds with soil components, has resulted in the production and use of bio-fertilizers (17, 23 and 29). bio-fertilizer is a preservative material consisting of one or several specific beneficial micro-organisms or their metabolic products used to supply plant nutrients and d...

The use of renewable resources and inputs is one of the fundamental principles of sustainable agriculture that enables maximum crop productivity and minimal environmental risk. Nutrient management may be achieved by the involvement of organic sources, bio-fertilizers, and micro-nutrients. Indiscriminate use of chemical fertilizers to achieve high yield and to compensate for lack of nutrients an...

Estimating balanced nutrient requirements for soybean (Glycine max [L.] Merr) in China is essential for identifying optimal fertilizer application regimes to increase soybean yield and nutrient use efficiency. We collected datasets from field experiments in major soybean planting regions of China between 2001 and 2015 to assess the relationship between soybean seed yield and nutrient uptake, an...

To evaluate the effect of different soil amendments on the yield and nutrient uptake of Salsola plant in the dry bed of Urmia Lake, an experiment was set up as a randomized complete block design with eight treatments and three replications in the 2013-2014 time period. These treatments included mycorrhiza usage, sand in the seed bed, plastic in the  depth of 70 cm, plastic in the  depth of 70 c...

Nano fertilizers are new products which contain readily available nutrients in the nano scale range and are preferred largely due to their efficiency. This research was conducted to assessment the effect of nano chelated of micro nutrient on agronomic traits of Cowpea via factorial experiment based on randomized complete block design with four replications during 2016 seasonal year. The treatme...

A field study was undertaken during winter (rabi) season of 2013-2014 to explore the effect of graded levels of fertilizers and bio-fertilizers on yield of chickpea, protein content in chickpea seeds and nutrient uptake by the crop. Significantly higher seed and stover yields (1854, 2722 kg ha-1, respectively) were recorded with application of fertilizer @ 100% RDF (25:50:00, kg N:P:K ha-1). Re...
