| Abstract | ||
| Two field experiments were carried out at Gemmeiza Agricultural Research station, EI-Gharbia Governorate during two seasons (2002 and 2005). The main objective of this investigation was to study the effect of bio-fertilizer (Rhizobacterein) as a method to decrease the levels of mineral nitrogen fertilizer of Giza 89 cotton variety using 60 kg/fed. without Rhizobacterein (as control) and using 30, and 45 N/fed. with Rhizobacterein at thinning, squaring and flowering stages On some cotton plant growth traits and attributes, earliness seed cotton yield / fed. and its components and net income. Results can be summarized as follows: Application of bio-fertilizer (Rhizobacterein)1 at treatment (8) [45 kg N/fed. + Rhizo. (2 L.Ifed. squaring) + 2 L.Ifed. flowering stage]. Significantly increased plant height, number of fruiting branches / plant, boll weight, number of open bolls / plant, seed cotton yield / fed. and lint percentage in both seasons. Also, applying bio- fertilization significantly increased the net income / fed. as compared with the check treatment. Also, using bio-fertilizers Significantly increased dry weight of plant organs during different growth stages and significantly increased leave contents of chlorophyll, carotinoids, nitrogen, oil and protein contents in seeds. | ||
