Effect of fungal inoculation and different levels of chemical fertilization on wheat growth and production (Triticum aestivum L.)

摘要

The field experiment was carried out in Al-Bidaa area in Al-Shatra district using RCBD design and three replications to study the effect of biofertilizer with Trichoderma harzianum and Mycorhiza and their interaction and three levels of chemical fertilization are 0, 50% and 100% of wheat fertilizer recommendation (urea 200 kg N ha-1, triple superphosphate 100 kg P2O5 ha-1 and potassium sulfate 80 kg K2O ha-1) and its effect on plant height, dry weight of vegetative total, total yield to seed and plant content of NPK at flowering stage. The results showed that fungal inoculation treatments significantly exceeded the rest of the treatments and gave the interaction treatment between Trichoderma harzianum and Mycorhiza fungi and 100% level of chemical fertilization highest values in dry weight, total wheat yield and plant content of nitrogen and phosphorus by 168.81%, 64%. 69%, 89.54% and 94.76% respectively, compared to the comparative treatment (noninoculated and non-chemically fertilized), which gave the lowest values for the above studied traits, and the overlap treatment between the mixed fungal inoculation and the level of 50% of the fertilizer recommendation chemical (A3K1) was not significantly different from the treatment of chemical fertilization by 100% of the fertilizer recommendation chemical, whether fungal or non- inoculated. This indicates that the mixed fungal inoculation has reduced the need for chemical fertilization by 50%.
