Effect of Biofertilization on Yield and Yield Component of Three Potato Cultivars (Solanum tuberosum L.).
Abstract Field experiments were conducted at the Experimental Farm of Faculty of Agriculture, Assiut, Egypt in two consecutive winter seasons 2004-2005 and 2005-2006 to determine the effects of three potato cultivars (Diamant, Cara and Spunta) and three commercial biofertilizers (Microbein, Rhizobacterin and Phosphorein) on potato germination and growth parameters under Assiut conditions. Diamant cultivar gave the highest and Cara gave the lowest germination percentage per plot in the two seasons. Non inoculated plots gave significantly the highest percentage (87.2%)of germination percentage per plot after 45 days from planting. Potato seed tubers of cultivar Diamant gave the highest total yield per feddan (0.42 ha)when inoculated with Phosphorein biofertilizer than the other two cultivars in the both seasons. Spunta gave the highest average weight of tubers in the two seasons, while Cara gave the lowest values. Rhizobacterin biofertilizer gave the highest average weight of tubers in both seasons, while the lowest average weight of tubers was recorded with Microbein biofertilizer treatment. The highest numbers of marketable, number of final plants at harvest time and the under size tubers were obtained from cv. Diamant in the two seasons. Cultivar Diamant significantly gave the highest number of main stems per hill and average number of leaves per plant in both seasons. Inoculation of potato seed tubers had no significant effect on the number of main stem per hill and average number of leaves per plant in the two seasons.
