Abstract
The current work aimed to evaluate the effect of P mineral fertilization, compost source and phosphate solubilizing bacteria (PSB) on wheat yield Triticum aestivum, L. (var. Msr1) and its components in calcareous soil. A pot experiment was conducted inside a greenhouse at the Faculty of Technology and Development, Zagazig University, Sharkia Governorate, Egypt during 2019/2020 winter season. The experiment was laid out in split split plot design with three replications. The main and sub plots were 0, 15 ، 30 kg P fed-1 and 15 m3 fed-1 compost (C1 , C2) respectively. Sub sub-plots were three rates of 0, 1 and 2 L fed-1 PSB. The results indicated that the values of grain yield (GY), straw yield (SY), biological yield (BY), harvest index (HI), crude protein (CP), N,P and K uptakes, agronomical N use efficiency (ANUE), N recovery efficiency (NRE), agronomical K use efficiency (AKUE), K recovery efficiency (KRE), and physiological K use efficiency (Ph.KUE), increased significantly with increasing P fertilizer level as well as with rising  (PSB) rate from 0.0 to 2 L fed-1. Compost1 (C1) was superior to compost2 (C2) in relation to its impact on all studied agronomic traits, (CP), N uptake, (ANUE), (NRE), agronomical P use efficiency (APUE), physiological P use efficiency (Ph.PUE), (AKUE) and (Ph.KUE). The best interaction treatment that achieved the highest values of most studied parameters was (30 kg P fed-1+ C1 + 2 L bio-fertilizer fed-1) flowed by (15 kg P fed-1 + C1 + 2 L) without any significant differences.
