Abstract

Two farm experiments were completed at private farm in Qalyobia Governorate, Egypt through the two sequent winter seasons of 2016/2017 and 2017/2018. The research aimed to investigate the influence of soil inoculation of P-fixed bacteria at levels of (0, 1 and 2 kg/fad.) with foliar sprinkle of a nutrient compound (Aquacool) on the growth, total bulbs yield and its components as well as bulb physical quality of onion plants cv Giza 20 grown in clay loam soil conditions. The obtained results specified that, the biggest values of plant growth criterion were achieved when sprinkle by highest level of Aquacool up to (2 cm/L) with inhibition to soil inoculation with P-fixed bacteria (phosphorein) has been set at rising standard (2 kg/fed.) as disparity to the other interaction treatments. These results held well in the two empirical seasons.
