Abstract: This study was carried out at Sids Agricultural Research Station,Beni-Suef Governorate, during 2006 and 2007 seasons. The work wasdesigned 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 interactionson some growth characters, yield and its components and some fiberproperties of Giza 80 cotton cultivar.The obtained results could be summarized as follows:-* Use of mineral and biofertilizer had a significant effect on all growthand yield characters in both seasons except seed index in secondseason and fiber properties except micronair reading in both seasons.* Usa of mineral fertilizers alone recorded the highest average of plantheight, boll weight (first season), No. of sympodial branches/plantand seed cotton yield/fed., in the two seasons.* Use of 75% mineral fertilizers with Rhizobacterin, phosphorien andpotassyomage recorded the best averages of position of firstsympodial node and seed cotton yield/fed. While, use 50% mineralfertilizer with all biofertilizer gave the highest values of No. of openbolls/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 understudy in both seasons.
