Allelopathic effects of plant residues is an important research avenue regarding optimization of rotation systems in agronomy. The aim of this study was to investigate the allelopathic effects of four plant residues, namely, black cumin, dragonhead, dill, and soybean on the germination and growth of wheat (Triticum aestivum) in different cropping systems. Results showed that applicatio...
background; dithiocarbamates, the main group of fungicides, are used to control about 400 pathogens in more than 70 crops. these pesticides are widely applied to crops including potato, cereal, apple, pear and leafy vegetables throughout the world since 1960. from the late 1980s, using these fungicides has caused much debate among regulators about their long-term effects on consumers and occupa...
nowadays, the development of anti cancer drugs is an important subject in pharmacology. bisphosphonates (b.p) are a great choice for design and production of the types of drugs which not only could perform as anti cancer agents but also could inhibit the function of acetyl cholinesterase (ache). ache hydrolyzes the acetylcholine (which is a neurotransmitter in nervous system) using the oh in i...
in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...

Due to high production of organic residues such as sewage sludge and compost, land application is probably the best way to prevent accumulated residues in the environment. However, the risk involved in the land application of organic residues should be evaluated prior to the assessment of their economic and fertilizer values. The objective of this study was to evaluate the effect of organic res...
This research was conducted to evaluate the nutritional value of vicia faba residues processed with some chemical compounds using in vitro and nylon bag techniques. Treatments included unprocessed vicia faba residues (control) and processed with water (2.5 lit/kg DM), calcium oxide (160 g/kg DM), hydrogen peroxide (57 ml/kg DM) and sodium hydroxide (50 g/kg DM). The chemical composition o...
The sago palm grows without the need for any form of fertilization, apart from some ground clearing during its first year of growth. It thrives mainly on peat soil which is unsuitable for most other crops. These make sago palm the best option as the starch source for tropical countries. Although the initial waiting period is long (up to 10 years for the plant to be harvestable), sago is the wor...
