Abstract

Two field experiments were conducted during 2012 and 2013 seasons in the Experimental Farm of
Agriculture Research Station, Agric. Res. Centre at Ismailia, Egypt to study the effect of four levels of phosphatic
fertilizer i.e. 0, 15.5, 23.25 and 31.0 kg P2O5/fad (faddan = 4200 m2) combined or separate with applying the
biofertilizers phosphorine or microbin on different growth characters and leaf chlorophyll content of two Peanut
varieties Giza-6 as erect cv and Gereogry as spread cv. Giza-6 surpassed significantly Gereogry in leaf area/plant, LAI,
dry weight of leaves and dry weight of stem and branches, while Gereogry surpassed significantly Giza-6 in plant
height, leaf chlorophyll content, number and dry weight of pods/plant and total dry weight of plant. That was held true
at different stages of growth i.e. 70, 85 and 100 days from sowing. Increasing phosphorus fertilizer up to the
highest level 31.0 kg P2O5/fad with and without biofertilizers phosphorine or microbin increased significantly all the
aforementioned growth traits at different stages of growth. It is worthy to note that biofertilizers phosphorine or
microbin increased the efficiency of peanut plants in utilizing phosphatic fertilizers, which in turn had favorable effect
on peanut growth, consequently increased the different growth characteristics at different growth stages and the two
biofertilizers almost did not differ significantly in this respect.
