Enhancing sugar pea productivity and phosphorus solubility by using different bio-fertilizers in sandy soil.
Abstract: Two field experiments were carried out during two successive winter seasons of 2011/2012 and 2012/2013 at the Experimental Farm, El Kassasein Research Station, Ismailia Governorate, to clarify the effects of partial substitution of chemical phosphorus fertilizer by the inoculation with mixed genera of Arbuscular mycorrhizal fungi (AMF) and Bacillus megaterium bacteria on growth, yield and pod quality of sugar pea plants (Pisum sativum var. macrocarpon) cv. Giant sugar grown under sandy soil conditions using drip irrigation system.
Results show that there were significant increases in vegetative growth characters, yield and it's components as well as some chemical constituents of pods as a result of increasing mineral phosphorus fertilizer level from 25% up to 100% of the recommended dose. Inoculation of sugar pea seeds with AMF + B. megaterium recorded the maximum values of vegetative growth characters, yield and it's components as well as chemical constituents of pods compared to the individual treatment from AMF or B. megaterium.
The interaction treatment between mineral phosphorus fertilizer at 100% of recommended dose plus dual inoculation of seeds with AMF and B. megaterium gave the highest values of vegetative growth characters, yield and it's components as well as chemical constituents of pods followed by the interaction between mineral phosphorus at 75% of the recommended dose plus dual inoculation of AMF and Bacillus megaterium without significant differences between them in most cases.
The highest values of nitrogenase, dehydrogenase enzyme activities, number of nodules and total count of B. megaterium colony were recorded with AMF + B. megaterium + 50 or 75% phosphorus after 80 days from sowing in both seasons. While, the highest significant effect of AMF colonization was recorded when combined with the dual treatment plus 25% phosphorus level
