Traits related to nitrogen fixation may be used as indirect selection criteria foraflatoxin resistance in peanut. The aim of this study was to investigate therelationship between N2 fixation traits and aflatoxin contamination in peanut underdifferent drought conditions. Eleven peanut genotypes were evaluated under threewater regimes for two seasons in the field. Data were observed on kernel inf...

Chemical fertilizer use in agricultural areas causes a variety of issues, including pollution, health risks, disruption natural ecological nutrient cycles, and the loss biological communities. In this case, chemical fertilizers, herbicides, other supplements are replaced by plant growth promoting bacteria for sustainable agriculture. The present research work focus on isolation from Kadi vegeta...

BACKGROUND Sale of organic foods is one of the fastest growing market segments within the global food industry. People often buy organic food because they believe organic farms produce more nutritious and better tasting food from healthier soils. Here we tested if there are significant differences in fruit and soil quality from 13 pairs of commercial organic and conventional strawberry agroecos...

Diazotrophs that carry out the biological fixation of atmospheric dinitrogen (N 2 ) replenish biologically available nitrogen (N) in soil and are influenced by input inorganic organic substrates. To date, little is known about effects combined substrate addition N fertilization on diazotroph community composition structure purple soils. We investigated straw mulching communities quantifying seq...

The main directions of research on perennial grasses in the field feed production Feed Institute are revealed. analysis was carried out grasses: clover, alfalfa, galega and grasses. In chronological order, indicating names positions researchers, a list all areas on: introduction culture is given; terms, methods sowing, norms sowing seeds single-species mixed phytocenoses; selection cover crops;...

In previous studies, respiring Bradyrhizobium sp. strain 32H1 cells grown under 0.2% O2, conditions that derepress N2 fixation, were found to have a low proton motive force of less than -121 mV, because of a low membrane potential (delta psi). In contrast, cells grown under 21% O2, which do not fix N2, had high proton motive force values of -175 mV or more, which are typical of respiring bacter...

The green ciliate Paramecium bursaria contains several hundred symbiotic Chlorella species. We previously reported that symbiotic algal carbon fixation is enhanced by P. bursaria extracts and that the enhancing factor is a heat-stable, low-molecular-weight, water-soluble compound. To identify the factor, further experiments were carried out. The enhancing activity remained even when organic com...

Two field trials were conducted to determine the effect of P-K solubilizing bacteria and nitrogen chemical fertilizer on growth, yield nitrate in leaf mustard greens Brassica juncea L.) cultivated acid sulfate soils. Eight bacterial strains composed 3 Acinetobacter calcoaceticus 5 Rhizobium sp., liquid directly watered into plant at stages [6, 12 21 days after planting] during vegetable cultiva...

mumps is an acute contagious viral disease that usually manifests as inflam¬mation of the parotid glands. the disease may be associated with symptoms such as parotitis, orchitis and meningoencephalitis. 85% of cases occur in children under 15 years of age. the disease is rare below two years but increases with age, reaching a maximum at 5 to 9 years. some studies in iran showed that the highest...
