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. تفاصيل المقالة

BACKGROUND: Application of bio-fertilizers, especially the plant growth promoting bacteria, is most important strategy for the integrated management of the plant nutrition in the sustainable agriculture system with sufficient input. OBJECTIVES: Current study was conducted to investigation the effect of different rate of combination fertilizer and biological fertilizer and type of application biofertilizer on crop production 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: According result of analysis of variance effect of different level of fertilizer combination, method of application fertilizer (instead number of spikelet per spike) and interaction effect of treatments (instead number of spike per m2 and number of spikelet per spike) on all measured traits was significant. Mean comparison result of different level of fertilizer combination showed that maximum amount of seed yield (7032.1 kg.ha-1), biologic yield (15315 kg.ha-1), Harvest index (45.89%) number of spike per m2 (384.84), number of spikelet per spike, number of seed per spikelet (18.02), number of seed per spike (2.23) and 1000-seed weight (40.26 gr) 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. CONCLUSION: Generally result of this study revealed to save energy and produce economic yield application 70% Nitrogen with biofertilizer (Fla Wheat) at 50% seed treatment with 50% by irrigation recommended. تفاصيل المقالة

BACKGROUND: Seed yield, as the most important quantitative characteristic, will be a result of genotype, environment and genotype-environment interaction effects. OBJECTIVES: Current study was done to assess effect of different rate of combination fertilizer and biological fertilizer and type of application biofertilizer on effective characteristics on seed yield. 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: According result of analysis of variance effect of different level of fertilizer combination, method of application fertilizes (instead NAR, CGR, spike length and number of spikelet per spike) and interaction effect of treatments (instead LAI, NAR, CGR, spike length, seed nitrogen content, seed protein content, number of spike per m2, number of spikelet per spike) on all measured traits was significant. The most positive and significant correlation was observed between seed yield and biologic yield (0.992**), harvest index (0.910**), 1000 seed weight (0.895**), number of seed per spikelet (0.771**), number of spike per square meter (0.707**) at 1% probability level. The traits of seed protein content (-0.680*), number of seed per spike (0.662*), spike length (0.653*), number of spikelet per spike (0.651*) and nitrogen protein content (-0.611*) had correlation with the seed yield was significant at 5% probability level. CONCLUSION: Characteristics such as of biologic yield, harvest index 1000 seed weight, number of seed per spikelet and number of spike per square meter had the most positive-direct effects on wheat seed yield can be proposal to plant breeder to more studied process such as stepwise regression and path analysis. تفاصيل المقالة
