Effect of Zeolite and mycorrhiza on some morphological characteristics and yield of maize at different levels of soil phosphorus

High chemical fertilizer applications caused many environmental problems particularly contamination of water and soil resources. One of the suitable solutions to prevent these problems and improve the quality of agricultural product, is applying biological fertilizers and mineral soil amendments. This study was carried out to consider the effects of mycorrhizal fungi and zeolite on some morphological and agronomic characteristics of maize (single cross 704) at different levels of phosphate fertilizer at agricultural faculty of Shahrood university. The factorial experiment was performed based on the randomized complete block design (RCBD) with three replications. The experiment factors included mycorrhizal fungi at two levels (with and without), zeolites at two levels (0 and 9 tons per hectare) and triple superphosphate fertilizer at three levels (0, 50 and 100 kg per hectare). The results showed that zeolite and phosphate fertilizer increased the height (25/67%) and stem diameter (13/80 %) of corn plant. In zeolite with mycorrhizal fungi treatment plant height and LAI increased 24/96%, 11/46% respectively. The 100-seed weight of corn increased in phosphate fertilizer, mycorrhizal fungi treatment. Phosphorus content of corn seed was significantly amplified by mycorrhizal fungi. The interaction of zeolite and mycorrhizal significantly amplified the k content of corn seed. The use of mycorrhizal fungi with zeolite improved the physiological and agronomic characteristics of maize. The results of this experiment can be used in organic and sustainable agricultural systems.
