Peanut plant growth and yield as influenced by co-inoculation with Bradyrhizobium and some rhizo-microorganisms under sandy loam soil conditions

Effect of Salicylic acid, Biofertilization and Sowing Dates on Peanut (Arachis hypogaea L.) Yield under Semi-arid Conditions

“…The maximum value of plant height (42.62 and 43.73 cm), weight of pods per plant( 10.62 and 11.57 g), number of pods per plant (9.86 and 10.25), 100-seeds weight ( 35.87 and 36.83 g), pod yields (831.47 and 857.36 kg/fad) and seed yields (425.11 and 449.47 kg/fad) protein combined yield ( 87.4 and 93.4 kg/fad) and oil yields (158.6 and 171.1 kg/fad) were obtained by biofertilized peanut plant with mixed biofertilization treatments (PDB + PS) through the first and second seasons, respectively. These results in accordance with Badawi et al (2011), they reported that Co inoculation of Peanut with Bradyrhizobium and PGPRs significantly magnified the Peanut yield (41%) during two growing seasons, synergy inoculation between Bradyrhizobium and PGPRs led to further increases in all studied parameters and strengthened the stimulating effect of bacterial inoculation.…”

Phosphate solubilization and phytohormone production by endophytic and rhizosphere Trichoderma isolates of guanandi (Calophyllum brasiliense Cambess)

“…Gravel et al (2007) observed the production of IAA by T. atroviride, using the precursors L-tryptophan, tryptamine and tryptophol. The species T. harzianum also demonstrated the ability to produce this phytohormone, according to Badawi et al (2011). Following the inoculation of cytokinin-producing microorganisms, increases in the weights of the cotyledons were observed, and for the microorganisms producing gibberellins, increases in the sizes of the hypocotyls and in the weights of the cotyledons were observed (Cattelan, 1999).…”

“…Carvajal et al (2009) reported the potential to solubilize phosphates in 20% of 101 isolates of Trichoderma spp. Badawi et al (2011) showed that T. harzianum had a greater ability to solubilize phosphate when compared with Bradyrhizobium spp. and Serratia marscescens.…”

Changes in Soil Chemical Properties in Response to Application of Phosphorus Sources in Legume Sorghum Cropping Systems

“…Root length and number of cluster roots was observed to be greater in MPR experiments compared to TSP experiments (results not shown). Legumes can release locked P from MPR (Badawi et al, 2011). Besides, MPR had a liming effect to the soil as it contains calcium carbonate (Szilas et al, 2007) and thus raised soil pH creating suitable environment for the survival of rhizobium bacteria responsible for N fixation (Dakora and Phillips, 2002).…”

“…Li et al (2007) performed a 4-yr field experiment in which maize and faba bean in alternating rows (intercropped) reported a rhizosphere effect of faba bean on maize. Legumes are known for their potential in P solubilization (Badawi et al, 2011). Legumes can enhance PR dissolution through acidification of the rhizosphere and exudation of organic acids (Pypers et al, 2007).…”
