Abstract
Increased cost of chemical phosphate fertilizer in the world and huge reserves of indigenous phosphate rocks reveals the importance of using of these resources. Little information is on the combined effect of mycorrhizal fungi and foliar application of P and the types of phosphate rocks in phosphate uptake. An experiment was conducted in during 2011-2012 growing season to determine the effects of foliar and pre-plant application of P on wheat yield and yield components in wheat inoculated with arbuscular mycorrhizal (AM) fungi and noninoculated plants at Research Fields of University of Tehran (Karaj), Iran. The experiment was laid out as a split plot factorial based on randomized complete block design using four replicates. The first factor was (a) foliar application of phosphorus at four levels (a1=0, a2=6, a3=8 and a4=10 kg ha-1), the second factor (b) was wheat planting in the presence or absence of mycorrhizal fungi and the third factor was (c) pre-plant application of P at three levels (c1=recommended dose, c2=25% lower than recommended dose and c3=50% lower than recommended dose). Results indicated that the highest grain yield was found in plots received foliar P at 8 kg ha -1 (7.89 ton ha-1) and plots with pre-plant P at recommended dose (7.91 ton ha -1 ). The minimum grain yield was related to plots with foliar application of P and without mycorrhizal (6.67 ton ha -1 ). The greatest and lowest biological yield were detected in plots with pre-plant P at recommended dose (17.4 ton ha-1) and 25% less than recommended dose (14.9 ton ha -1 ), respectively.
