Effect of three promising biofertilization formulations on tuber yield of some potato (Solanum tuberosum L.) cultivars in Assiut region of Egypt

Abstract

An experiment was conducted at Experimental Farm of Faculty of Agriculture, Assiut University, Egypt in two consecutive winter seasons to determine the effects of three potato cultivars and three biofertilizers (Rhizobacterin, Microbein and Phosphorein) on potato quality and yield under Assiut conditions. Cultivar Diamant registered the highest number of stems per plant, total yield per ha, highest numbers of marketable tuber yield per plant in the two seasons. The lowest values of the previous characters were registered in Spunta except total yield of tubers, which was recorded in cv. Cara. Regard to biofertilization treatments, Phosphorein biofertilizer and control treatments registered the highest total yield per ha in both seasons. Rhizobacterin biofertilizer registered the highest average weight of tubers in both seasons. Control treatment and inoculation of potato seed tubers with different biofertilizer sources registered no significant effect on number of main stem per hill, number of marketable tuber yield per plot in the two fall seasons
