Résumé
Two field experiments were carried out on a highly calcareous sandy clay loam soil at Nubaria Agricultural Research Station which is located at 47 km Alexandria- Cairo desert road (47 km south west of Alexandria city) representing the newly reclaimed land of north west of Egypt, during the two successive seasons of 2008 and 2009. The study was suggested to evaluate the effect of organic (Farmyard manure, FYM) fertilizer level and mineral- bio- fertilization and their interaction on NPK concentration in cotton leaves, growth, earliness, yield and yield components and fiber properties. The cultivar used, in the present investigation, the commercial Egyptian long staple cultivar ; Giza 86. Three farmyard manure (FYM) fertilizer levels were applied as follows : A1 : zero m3 FYM, A2 : 10 m3 FYM and A3. 20 m3 FYM per feddan. Eight mineral- and bio- fertilization treatments were applied as follows : B1. The full recommended doses of NPK. B2. ½ NPK + Microbein bio- fertilizer. B3. ½ NPK + Mycorrhizae bio- fertilizer. B4.½ NPK + Potassiomage bio- fertilizer. B5. ½ NPK + Microbein and Mycorrhizae bio- fertilizers. B6. ½ NPK + Microbein and Potassiomage bio- fertilizers. B7.½ NPK + Mycorrhizae and Potassiomage bio- fertilizers. B8- ½ NPK + Microbein ,Mycorrhizae and Potassiomage bio -fertilizers.
