Two field experiments were conducted to evaluate the effect of bio-fertilizers (nitrobein + phosphorein) when used with half or full doses of chemical fertilizer in presence of Algreen 600 foliar spray at 1g/L and organic fertilizer (compost 10 m3/fed.) on some growth parameters, photosynthetic pigments ,minerls and oil yield of basil (Ocimum basilicum, L.) cv. Genovese plants during 2012/2013 and 2013/2014 seasons. Also, interaction effects between Algreen 600 and the applied fertilizer treatments on growth, chemical composition and oil productivity were studied as well. The results showed that, the applied treatments of fertilizers and Algreen 600 as well as their combinations significantly increased most growth parameters i.e. plant height, number of branches, fresh and dry weight of plant (g). Also, photosynthetic pigments i.e. chlorophyll a and b, minerals i.e. N, P and K, especially the treatments of bio-fertilizer or Algreen 600 in the two cuts in both seasons. Additionally. The treatment of 50% NPK+bio-fertilizer+Algreen 600 induced high significant increments in this concern in the two seasons Also, oil yield in leaves gave the maximum values when plants treated with bio-fertilizers, Algreen 600 and 50% NPK+bio-fertilizer+Algreen 600 treatments as compared with those of individual application of chemical fertilizer or untreated ones. Thereby, it could be recommended that the treatments of bio-fertilizer, Algreen600 and NPK at 50% +bio-fertilizer + Algreen600 could be used to improve growth and oil productivity of basil plant. |
