| Abstract | ||||
| Two field experiments were carried out at a private farm at Sakkara, EL-Badrasheen, Giza, Governorate, Egypt, during two successive Summer seasons of 2004-2005 to study the influence of cyanobacteria inoculation in different rates(0,25, 50 and 100% of the recommended dose,i.e.,10 kg dried cyanobacteria inoculum fed-1) individually or in presence and/ or absence of different nitrogen levels (25, 50 and 100% of the recommended dose, (i.e.),100 kg N fed-1) on maize yield and 100-grain weight, some maize grain technology characters (protein and oil yields fed-1, protein, carbohydrates and ash percentages) as well as the maize mineral contents. Results revealed that cyanobacteria inoculation enhanced all maize tested parameters.The highest maize yield values were due to 100% N + 100% cyanobacteria and they were significantly higher than the other tested treatments received the other different combination of cyanobacteria and nitrogen. Cyanobacteria inoculation at the rate of 100% N + 100% cyanobacteria the highest oil yield fed-1. The treatment of 50% cyanobacteria combined with100% N recorded the highest percentages of protein, oil and carbohydrate, while, the highest percentage of ash was due to 25% cyanobacteria combined with50% N. Due to both maize grains hulls and germ percentages, the highest ones were recorded by the treatment received 25% cyanobacteria combined with 50% N, while, maize grain endosperm gave its highest percentage due to the treatment of 25% cyanobacteria combined with 100 % N. As for maize grain mineral content, As for cyanobacteria inoculation had positively affected the maize grains mineral content ,i.e., Mg, Na, Zn, Fe, Ca and K. In conclusion, the use of cyanobacteria inoculation technology in cereal crop production such as maize may lead to reduce the amount of mineral nitrogen required for maize production as well as it ensures good yield quality and safe the environment contaminations resulted from the extensive use of the costly and hazard the so called mineral nitrogen fertilizer. | ||||
