The aim of this research was to investigate the effect of inoculation (Azotobacter chroococcum and actinomycetes) and nitrogen mineral fertilizers (doses of 60 kg N ha-1 and 120 kg N ha-1) on the yield of wheat and on the number and activity of certain microorganisms in rhizospheric soil. The investigation was carried out in humogley soil with three wheat varieties. The variants of the experime...

The research was conducted to evaluate growth of alfalfa mutan (plant height increment, number of leaves and dry matter production) in different Nitrogen Fertilizer and defoliation intensity. The design used was randomized block design 4x2 factorial with 3 replications. The first was dosage of Nitrogen fertilizerNitrogen (0, 30, 60 and 90 kg N / ha), the second factor was defoliation intensity ...

Nutrient recovery from biomass streams generates novel recycling-derived fertilizers (RDFs). The effect of RDFs depends on their nutrient content and variability, which can aid or hinder use by end-users. Detailed characterization help in evaluating product properties, whereas blending optimize ratios reduce variability. This study assesses ammonium nitrate (AN) stripping-scrubbing, water (AW) ...

Inappropriate and excessive irrigation and fertilization have led to the predominant decline of crop yields, and water and fertilizer use efficiency in intensive vegetable production systems in China. For many vegetables, fertigation can be applied daily according to the actual water and nutrient requirement of crops. A greenhouse study was therefore conducted to investigate the effect of daily...

in order to evaluate the effects of different levels of potassium and nitrogen on nitrogen use efficiency (nue) and yield of rapeseed (hyola 401), a field experiment was conducted at rice research institute of iran (rasht) in a factorial experiment based on a complete randomized block design with 3 replications for two years (2008-2010). the first factor was pure potassium fertilizer in three l...

With increased demand for traditional agricultural practices, they are increasingly insufficient. The use of nano-fertilizers is essential when aimed to increase plant production. In 2003, nanotechnology started be used in agriculture and food industry. This led change production systems. Nanotechnology has brought fundamental changes agriculture. included new tools have been detect pests treat...

in order to study of the effect of seed inoculation with pgpr on nitrogen and phosphorus use efficiency of spring wheat in different levels of nitrogen and phosphorus fertilizers, an experimental was conducted at the research farm of mohageh ardabili university, ardabil, iran during 2012 year. the combination of nitrogen fertilizer in three levels (0, 40 and 80 kg n/ha as urea) and phosphorus f...

It aims to examine the impact of nano and non-nano fertilizers on rice quality productivity. Rice is a staple food crop for large portion global population, use essential optimizing yields maintaining security. The emergence nano-fertilizers presents new opportunities enhancing nutrient efficiency, plant growth, quality. However, limitations in existing research, such as lack comparative studie...
