The Effect of Mycorrhiza Fungi (VAM) on Phosphorus Absorption by Corn (Zea Mays L.) at South West of Iran

Abstract

In order to understanding of the VAM effects on functions and nutrition of the corn, a research was conducted in Agricultural Research Center of Safi Abad, Khouzestan. The experiment was carried out based randomized complete block design at four replications. The treatments contain Mycorrhiza Fungi and phosphorous includes: A: Phosphorus according to soil test. B: VAM + Phosphorus according to soil test. C: Phosphorus according to 65% of soil test. D: VAM + Phosphorus according to 65% of soil test. E: Check treatment. This research was done to determine amount of absorbed macro and micro nutritious elements in shoot at early growth stage in corn plant. Result showed amounts of absorbed elements in shoot at any of the treatment levels were not different according to the statistical analysis results. Phosphorus content in plant was variable from 0.12 in treatment 5 to 0.18 % in treatment 1. Plant dry matter was variable from 28.60 in treatment 4 to 36.48 gram in treatment 1 and also the yield of fresh plant was variable from 260 in treatment 5 to 320 gram in treatment 2. The treatment caused plant root to be colonized by Mycorrhiza and using phosphorous fertilizer, compared to soil test (check treatment), was the greatest amount of uptake in corn plant.
