Subject(s): Online resources: In: Journal of the advances in agricultural researches 2002.v.7(1)Summary: This is the seventh part in a series of articles aiming at helping the cotton growers to optimize the cotton production in the desert regions. Two field experiments were conducted on a sandy loam soil at Nubaria Agric. Res. stn. during the summer season of 1999 and 2000 to study the response of Egyptian cotton cultivar Giza 70 to inoculation with Rhizobactrein or Nitrobein as commercial biofertilizers compared to non inoculation treatment on some plant growth attributes, earliness parameters, seed cotton yield/fed,its components, fiber properties and net return/fed under the three levels of N fertilizers (30,45 and 60 kg N/fed).The results indicated that application of 60kgN/fed signifiCantly increased plant height, number of sympodial plant, earliness parameters, seed cotton yield/plant, Its components, consequently seed cotton yield/ fed in the two seasons. While, N fertilizer levels had insignifiCant effects on first sympodial position, number of plants/fed at harvest, fiber length in both seasons, fiber strength and fineness in one season only. Application of Nitrobein followed by Rhizobactrein biofertilizers significantly increased plant height, earliness parameters, seed cotton yield/ fed and Its components compared with non-inoculation treatment.
