Background: Cropping system approach has gained importance in agriculture and relative enterprises. In agriculture, management practices are usually formulated for individual crops. However, farmers cultivating different crops seasons based on their adaptability to a particular season, domestic needs profitability, therefore production technologies should be developed keeping view of grown sequ...

Physiological responses to infection by strains of Rhizobium leguminosarum which differed in their capacity to reduce N(2) were determined in 26-day-old pea plants (Pisum sativum L. cv. Alaska) grown under uniform environmental conditions in the absence of combined N. The highest N(2) reduction rates, calculated from H(2) evolution and C(2)H(2)-dependent C(2)H(4) production measurements, were a...

Of 18 Rhizobium trifolii strains tested, 12 showed a high frequency of loss of nodulation ability after incubation in cultures at elevated temperatures. A correlation between loss of nodulation ability and loss of a large plasmid was demonstrated for R. trifolii. In some nonnodulating (Nod-) mutants, deletions occurred instead of total elimination of the plasmid molecule. The maximum curing eff...

This study investigates the synergy of Rhizobium phaseoli and Acidithiobacillus ferrooxidans in the bioleaching process of copper. The results showed that additional R. phaseoli could increase leaching rate and cell number of A. ferrooxidans. When the initial cell number ratio between A. ferrooxidans and R. phaseoli was 2 : 1, A. ferrooxidans attained the highest final cell number of approximat...

A field experiment was conducted during Rabi season 2021-22 at the experimental of Crop Research Farm, Department Agronomy, Naini Agricultural Institute, Sam Higginbottom University Agriculture, Technology And Sciences, Prayagraj, Uttar Pradesh. India which is located 250 30’ 42’’N latitude, 810 60’ 56” E longitude, and a height 98 meters above sea level. The Experiment laid out in Randomized B...

evaluation of genetic diversity is a considerable approach to screen within indigenous rhizobial population for compatible, highly effective strains, which can be further utilized as rhizobial inoculums. genetic diversity of rhizobium isolates from three clover species grown in soil samples of seven different geographical regions in iran was investigated by repetitive extra genomic palindromic ...

this research, for lowering the use of chemical fertilizer, was carried out using combinations of biological and chemical fertilizer on bean in rasht region in 2012 growing season. the experiment was conducted based on randomized complete blocks design with 12 treatments and three replications. experimental treatments included: control (no fertilizers and no inoculants), chemical fertilizers (n...

Cowpea (Vigna unguiculata) and mung bean (Vigna radiata) are important legume crops yet their rhizobia have not been well characterized. In the present study, 62 rhizobial strains isolated from the root nodules of these plants grown in the subtropical region of China were analyzed via a polyphasic approach. The results showed that 90% of the analyzed strains belonged to or were related to Brady...
