Effect of Water Stress and Biological Fertilization on Maize Growth, Chemical Composition and Productivity in Calcareous Soil

Ehab Azab

Abstract:
Objective: The present study was to estimated maize growth, chemical composition and productivity in calcareous soil under the effect of bio-fertilizer. Methodology: Two field experiments were conducted at Department of Botany, Faculty of Science, Zagazig University to study the effect of two different bio-fertilization treatments (Azotobacter crococcum+Mycorrhiza+Pseudomonas spp.) and (Azospirilium lipoferum+Bacillus megatherium var. phosphaticum+Bacillus subtillus ) accompanied with two mineral NPK levels {full (100%) and half (50%) dosages}, on maize cv. 30B9, under four water regime treatments; which missed one irrigation (second, third and fourth) beside the normal irrigation treatment as a control. Results: The obtained results confirmed that maize plants can tolerate water scarcity at the vegetative growth period (60 days). Missing the fourth followed by the third irrigation seemed to be the best after the control one. The bio-fertilization treatments, helped the plants to overcome the negative effects of water stress at any growth period. The first bio-fertilizer appeared to be more effective under water stress conditions if compared with the second treatment. Conclusion: Moreover, the full dosage of the mineral NPK fertilizer was found be the best followed by both first and the second bio fertilizer accompanied with the half dosage of the mineral NPK. It could be mentioned that, using the half dosage of the mineral NPK, the bio-fertilizers will be more logic.
