Response of maize plant to inculation by mycorrhiza (glomus mosseae) and phosphorus fertilization in gypsiferous soil

Abstract

Afield experiment was conducted by using (RCBD) in a sandy clay loam to study the effect of bio fertilization and deferent levels of phosphorus fertilizer on some properties of maize (Zea mays L.). Two sources of phosphate used tri super phosphate and fine rock phosphate at levels (0 , 90 , 135 , 180)kg P2O5.ha-1 and two levels of mycorrhiza (Glomus mosseae) (with out incolution and within incolution).The results showed that fungal bio fertilizer irrespective application of phosphorus fertilizer caused significantly increasing plant height, leaf area, diameter of steem, chlorophyll and percentage of (N , P , K) in leaves.The highest number when used bio fertilizer application with (135)kg P2O5.ha-1 tri super phosphate caused significantly increment (40.8 , 30.18 , 40.11 , 51.13 , 19.99 , 167.21 , 26.12)% respectively compared with treatment control and decreased 25% of tri super phosphate. The incolution with (180)kg P2O5.ha-1 fine rock phosphate gave results non-significant when used tri super phosphate without incolution.
