This study was carried out at Sids Agricultural Research Station, Beni-Suef Governorate, during 2006 and 2007 seasons. The work was designed to study the effect of different rates of mineral NPK fertilizers (60N, 22.5 P2O5 and 24 K2O kg/fed., respectively), three biofertilizers (Rhizobacterien, phosphorien and potassyomage) and their interactions on some growth characters, yield and its components and some fiber properties of Giza 80 cotton cultivar. The obtained results could be summarized as follows:- * Use of mineral and biofertilizer had a significant effect on all growth and yield characters in both seasons except seed index in second season and fiber properties except micronair reading in both seasons. * Usa of mineral fertilizers alone recorded the highest average of plant height, boll weight (first season), No. of sympodial branches/plant and seed cotton yield/fed., in the two seasons. * Use of 75% mineral fertilizers with Rhizobacterin, phosphorien and potassyomage recorded the best averages of position of first sympodial node and seed cotton yield/fed. While, use 50% mineral fertilizer with all biofertilizer gave the highest values of No. of open bolls/plant, boll weight (second season) and seed cotton yield /plant. * Use of 75% mineral (P) plus phosphorien led to increase boll weight (second season) and seed index. * Use of biofertilizers alone significantly decreased all characters under study in both seasons.
