iran is among the biggest emitters of greenhouse gasses in the world. agricultural sector has a remarkable role in non-renewable energy consumption and then, the environmental impacts in this country. in this regard, the environmental impacts of watermelon production as the most important melons produced in guilan province of iran were investigated through the life cycle assessment (lca) approa...

A pot experiment was carried out with maize to determine the phosphorus (P) plant-availability of different secondary P-fertilizers derived from wastewater. We analyzed the respective soils by P K-edge X-ray absorption near-edge structure (XANES) spectroscopy to determine the P chemical forms that were present and determine the transformation processes. Macro- and micro-XANES spectroscopy were ...

A serious problem in cultivation of ornamental plants is a lack scientific and applied program in fertilization, so that the plant nutrition focused on growth medium. A randomized completely design with 8 different fertilization methods with the use of ammonium sulphate, potassium sulphate, di ammonium phosphate, ferrilene and kristalon was conducted in three replications in a greenhouse of Cha...

in order to study the effect of on-farm seed priming and two bio-fertilizers on emergence and yield characteristics of chickpea, a factorial experiment was conducted in a randomized complete block design in hamedan with three replications in 2013. the factors consisted of phosphate fertilizer (0, 50 and 100 percent of recommended) bio-fertilizer (mycorrhizae, barvar2, both of them and no-applic...

Organic fertilizers play a significant role in organic systems and sustainable soil management. In general, organic fertilizers increase soil fertilization so can reduce the negative effects of the excessive use of chemical fertilizers and synthetic man-made fertilizers. This study was carried out in the Medicinal Plants Farm of Shahid Bakeri Higher Education Center of Miandoab during summer 20...

Phosphate (Pi) is an essential macronutrient that plays a central role in virtually all metabolic processes in plants, including photosynthesis and respiration. Despite its importance, Pi is one of the least available nutrients in many ecosystems, and is a frequent limiting factor for plant productivity. Although plentiful in the earth’s crust, soil Pi often exists in insoluble mineral forms th...

Agrochemical is evolved by the contraction and combination of words agricultural and chemical, and is a generic term used for the various chemical products typically used in agriculture. Agrochemicals essentially help in intensifying crop production and to reduce the effects of pests and parasites on farm animals. Agrochemical basically refers to the broad range of pesticides and fertilizers. A...

Background: Essential oil content and composition in medicinal and aromatic plants is highly affected by both biotic and abiotic factors. Objective: To investigate the effects of drought stress, zeolite and bio-fertilizers on morphological characteristics and essential oil constituents in Dracocephalum moldavica L. Methods: This experiment was conducted in the form of split factorial based on...

The aim of this study was to evaluate P availability, P and C contained in the microbial biomass, and enzymatic activity (acid phosphatases and β-glucosidases) in a Nitisol with the application of mineral and organo-mineral fertilizers. The experiment was performed in a protected environment with control over air temperature and soil moisture. The experimental design was organized in a "5 x 4" ...
