crop rotation affect on crop nitrogen uptake and nitrogen use efficiency (nue). crop rotations with high nue decrease energy use and increase level of sustainability in agro ecosystems. the objectives of this research were to determine the suitable double cropping system for enhancing nue and evaluate the effects of crop rotation, n fertilizer rate and return of crop residue on nue. this study ...
Increasing fertilizer consumption has led to low fertilizer use efficiency and environmental problems. Identifying nutrient-efficient genes will facilitate the breeding of crops with improved fertilizer use efficiency. This research performed a genome-wide sequence analysis of the A (NFYA), B (NFYB), and C (NFYC) subunits of Nuclear Factor Y (NF-Y) in wheat (Triticum aestivum) and further inves...
in order to evaluate the effect of different levels of drought stress and nitrogen fertilizer on growth of strawberry plants, present study was conducted in the mazandaran province in 2010. experiment was carried out as factorial based on randomized complete block design with three replications. drought stress treatments (30, 50 and 70% maximum allowable depletion of moistur (mad)) and nitrogen...
In order to investigate the effects of different nitrogen fertilizer levels and water stress during milky and dough stages on grain yield, yield components and water use efficiency of corn hybrid SC 704 (late maturing, non prolific and dent type), a field study was conducted. The factorial design of the study comprised of a randomized complete block with four replications. Four levels of nitro...
In order to study the effect of phosphate biofertilizer and chemical fertilizers of nitrogen, phosphorus and sulfur on some growth and yield components of Camelina sativa L., a study was conducted based on a factorial experiment; this was done in a randomized complete block design with three replications at Kazeroon during the 2016 growing season. Treatments included bio-based phosphorus (P)...
In this research, a comprehensive simulation model for water cycle and the nitrogen dynamics modeling including all the important processes involved in nitrogen transformations such as fertilizer dissolution, nitrification, denitrification, ammonium volatilization, mineralization, immobilization as well as all the important nitrogen transportation processes including nitrogen uptake by the plan...
1.1 Biological nitrogen fixation and nitrogen nutrition in soybean plants Biological nitrogen fixation is one of the most important processes for ecosystem to access available N for all living organisms. Although N2 consists 78% of atmosphere, but the triple bond between two N atoms is very stable, and only a few group of prokaryotes can fix N2 to ammonia by the enzyme nitrogenase. Annual rate ...
BACKGROUND: Fertilizer management plays an important role to achieve sustainable agriculture. OBJECTIVES: Current study was conducted to assess response of agrophysiological traits of wheat to apply different level of fertilizer and biologic fertilizer (Phosphorus and Nitrogen). METHODS: This research was carried out via factorial e...

BACKGROUND: Fertilizer management plays an important role for obtaining satisfactory yields and to increase crop productivity. Nutrient management may be achieved by the involvement of organic sources, bio fertilizers, and micro-nutrients. OBJECTIVES: Assessment effect of chemical and biological fertilizer on seed yield, its components and plant height of...
