Assessment Effect of Different Level of Combination Chemical and Biological Fertilizer and Several Type of Application Fertilizer on Morphological and Qualitative Traits of Bread Wheat

BACKGROUND: Management of nutrients, especially nitrogen, in order to wheat economic production and maintain sustainable agriculture and to provide food security, is considered to have an important priority. OBJECTIVES: Current study was done to assess effect of different rate of combination fertilizer and biological fertilizer and type of application biofertilizer on morphological and qualitative characteristics of Wheat. METHODS: This research was carried out via factorial experiment based on randomized complete blocks design with three replications along 2020-2021 year. The treatments included different rate of combination Nitrogen fertilizer and Biofertilizer (Fla Wheat) (a1: 100% nitrogen with nonuse of Fla Wheat as control or N100/F0, a2: 70% Nitrogen with Fla Wheat or N70/F1, a3: 40% Nitrogen with Fla Wheat or N40/F1) and several methods of applying biofertilizer (Fla Wheat) (b1: 100% Seed treatment, b2: 100% by irrigation, b3: 50% seed treatment with 50% by irrigation). RESULT: Result of analysis of variance indicated effect of different level of fertilizer combination, method of application fertilizer (instead spike length) and interaction effect of treatments (instead spike length, seed nitrogen content and seed protein content) on all measured traits was significant. Mean comparison result of different level of fertilizer combination showed that maximum amount of plant height (84.71 cm), spike length (11.68 cm), seed yield (7032.1 kg.ha-1) and seed nitrogen content (2.13%) was noted for N100/F0 and minimum of those belonged to N40/F2 treatment. As for Duncan classification made with respect to different level of Method of application fertilizer the highest and lowest amount of measured traits was for M3 and M2 treatment (instead spike length and seed protein content). Seed protein content against treatment showed reverse trend. CONCLUSION: Based on result of current research according economically situation consume 70% Nitrogen with biofertilizer (Fla Wheat) at 50% seed treatment with 50% by irrigation can advised to producers.
