Fertilizer management plays an important role in obtaining satisfactory yields from maize. In addition, fertilizer management is essential for achieving sustainable agriculture and protecting the environment. This research was conducted by split plot experiment based on randomized complete block design with four replications. Main factor was integrated with chemical and biological fertilizers i...

Chemical composition of soil organic carbon (SOC) is central to soil fertility. We hypothesize that change in SOC content resulting from various long-term fertilization strategies accompanies the shift in SOC chemical structure. This study examined the effect of fertilization strategies along with the time of fertilizer application on the SOC composition by 13C nuclear magnetic resonance (NMR) ...

The long-term application of excessive chemical fertilizers has resulted in the degeneration of soil quality parameters such as soil microbial biomass, communities, and nutrient content, which in turn affects crop health, productivity, and soil sustainable productivity. The objective of this study was to develop a rapid and efficient solution for rehabilitating degraded cropland soils by precis...

in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...

Sustainable agriculture can increase the efficiency of resource utilization, provide longer productivity and create a balance in the environment. A field experiment was conducted to study the use of organic and chemical fertilizers on biomass, essential oil content and essential oil yield as well as chemical compositions of Dracocephalum polychaetum Burnm in the first and second cutting. The tr...

In line with sustainable agriculture development, an experiment was conducted including tillage as the main factor in two conventional systems (plowing and mixing fertilizer with soil) and no tillage (leaving residuals of green manure and direct corn sowing). The fertilizer resources were T0: control, T1: barley green manure without chemical and manure fertilizers, T2: barley green manure with ...

Common purslane is a warm season plant which had a lot of medicinal properties. An experiment was conducted as a split plot design arranged  in completely randomized block design with three replications in the research field of Agricultural Sciences and Natural Resources University of Khuzestan during 2015-2016. In this experiment, the main plots consisted of four levels of irrigation intervals...
