Effect of Growing Area on Yield Traits, Fiber and Yarn Properties in Egyptian Cotton Genotypes by Using Biofertilizer Inoculation, Vermicompost and Algae Extract. تأثير منطقة الزراعة على صفات المحْصول وصفات جوُدة التيلة والغزل لبعْض التراکيب الوراثية فى القُطن المصْرى بإستخدام التلقيح الحيوى والفيرم کُمبوست ومُستخْلص الطحالب

These experiments were conducted to study the response of some Egyptian cotton, Giza 96 (extra-long stable) and stable)varieties its yield characteristic, lint percentage, fiber yarn properties when using bio-fertilizers such as vermicompost, Bacteria  bacteria inoculums (Bacillus polymxa, Bacillus megaterium circulans) algae extract under different growing area, Sakha region (clay soil) El-Nubaria (calcareous soil).Concerning effect treatments application on soil properties, thisresults showed a significantly increaseof organic matter, pHit was relatively insignificantly decreased vermicompost had positive effects levels N, P K. available. As biological count Bacteria, Fungi, Actinomycetes Carbon dioxide evolution rate it significant increase. The content cotton plant leaves chlorophyll A, B, Carotenoids Total phenols improved fertilizer compared control.The treatment with (vermicompost + bacterial inoculation 50% mineral recommended dose extract) proved superiority over rest treatments, especially in seed yield, which increased at 1.41 kentar per feddan 0.63(lint %) two control treatments. Data characteristics, recorded due cultivated regions.The difference among studied varieties may be growth habit each one environmental conditions, controlled by genetic factors efficient utilization inputs natural resources.
