Leguminous crops, possessing root nodules, fix and utilize atmospheric nitrogen. They are thus not dependent on industrially fixed nitrogen but add up to 30 kg of nitrogen / hectare to the soil and improve its fertility. Access to mineral nitrogen often limits plant growth, and so symbiotic relationships have evolved between plants and a variety of nitrogen-fixing organisms. These associations ...

In order to investigate the effect of seed inoculation with Plant Growth Promoting Rhizobactria (PGPR) on germination and some biochemical and physiological indices of Cumin (Cuminum cyminum L.) under salinity stress, an experiment was conducted. Experimental factors were included in seed priming in five levels (seed inoculation with three strains of Pf2, Pf25 and CHA0 of Pseudomonas fluorescen...

air pollution is the most important environmental problem of last century that threatens the health of living organisms, especially plants. so2 is one of the main air pollutants that can cause to imbalance in growth and physiological function of plant in high concentrations. symbiosis of rhizobium bacteria with alfalfa can cause increasing plant growth and plant resistance to abiotic stresses. ...

Wheat yields in organic production are significantly lower than those achieved conventional farming systems and Northern Europe farmers also struggle to achieve the processing quality levels demanded by millers bakers, especially winter-wheat crops. Here, we report findings of a 3-year pilot study which investigated potential increasing grain both standard (e.g., protein specific weights) selec...

Field experiment was conducted at the Instructional Farm of Krishi Vigyan Kendra, Chhatarpur during two consecutive kharif 2017-18 and 2018-19 to evaluate effect different biofertilizers along with 75 % recommended dose fertilizers on growth, yield, nutrient uptake, use efficiency B:C ratio greengram (Vigna radiata L.). Results revealed that application NPK seed treatment Rhizobium @ 10 g/kg so...

Chemical fertilizers, which contain a nitrogen (N) element, has been intensively used to increase the peanut productivity. However, unstable and high cost of N fertilizer, great demand for fertilizer sources have strongly increased strategical plan fixation (NF). Therefore, field research was carried out appraise ability Rhizobium sp. trains chicken manure (CM) on quality yield peanuts. This fo...

Nitrogen (N) fixation through legume-Rhizobium symbiosis is important for enhancing agricultural productivity and is therefore of great economic interest. Growing evidence indicates that other soil beneficial bacteria can positively affect symbiotic performance of rhizobia. Nodule endophytic plant growth promoting rhizobacteria (PGPR) were isolated from common bean nodules from Nakuru County in...

Early growth water stress reduces the extract and fresh oil of Silybum marianum L. (S. marianum) shoots. Two experiments were conducted to reduce effects early drought. Treatments in first experiment organic seed cover fillers at three levels (control, vermicompost, peat moss), hydrogel seven 2, 4, 6 g hydrogelF1 per kg OSC, hydrogelA200 cover), deficit (100, 50, 25% field capacity), second exp...
