Abstract | ||||
In two pot experiments, wheat (Triticum eestivum L .. var Sakha 8) plants were fertlized with the NPK levels of 25,50 and 100% as the main level. Under each NPK level, the biofertlizers nitro bien, phosphorine and phosphorine + nitrobien treatments were applied as the sub-main level. As the NPK level was increased, shoot length, number of tillers/plant, number of leaves/plant and the dry weight of shoots, roots and whole plant dry weights of wheat plant were significantly increased in both sampling dates. All the previously mentioned characters were significantly increased as a result of the all applied b iofertilizers treatments including n itrobien, phosphorine a nd p hosphoorine when compared to non-treated control treatment at both sampling dates. Grain yield/plant significantly increased as the NPK level was incraesed. Also, grain yield and yield components were increased due to the application of biotertinzers as compared to the non-treated control treatment. However, the highest values for grain yield/plant was obtained when treated with the biofertilizer phosphorine + nitrobien treatment. Application of NPK fertilization tended to increase mineral concentartions including total nitrigen, phosphorus. potassium and calcium as well as sugars in both shoots and roots of wheat plant at both sampling dates. Also, biofertilizer treatments tended to increase the same attributes when compared to the non-treated control treatment. Similar trend was obtained for total nitrogen. phosphorus, potassium and calcium as well as sugars concentrations in wheat grains at harvest. It might be concluded that applying NPK with biofertlizers treatments might improve wheat plant n utrtional status which leads to higher plant productivity . | ||||
