Evaluation Crop Production, Nitrogen Content and Oil yield of Corn in Affected Vermicompost and Iron Nano Fertilizer

BACKGROUND: Iron (Fe) is one of the essential elements for the plant and plays an important role in the many plant processes such as photosynthesis, respiration, nitrogen uptake and construction, and also in construction and development of chloroplasts in plants. Bio-fertilizers are more environmental friendly and in many cases, they have given the same or even better crop yields compared to mineral fertilizers. OBJECTIVES: This study was carried out to determine effect of different level of vermicompost and Nano iron fertilizer on quantitative and qualitative traits of corn. METHODS: This research was conducted according split plot experiment based on randomized complete blocks design with three replications along 2018 year in research farm of Islamic Azad University of Ahvaz Branch. Main plot included three level of vermicompost (V0: nonuse of vermicompost or control, V1: 5 t.ha-1 vermicompost, V2: 10 t.ha-1 vermicompost) was consumed at planting stage. Also subplots consisted four level of Nano iron fertilizer (F0: Nonuse of Nano iron fertilizer or control, F1: 0.002 L.ha-1, F2: 0.004 L.ha-1 and F3: 0.006 L.ha-1 Nano iron fertilizer) was used at 3 to 4 leaves stage. RESULT: Based on result of analysis of variance effect of different level of vermicompost, Nano iron fertilizer and interaction effect of treatments on all studied traits was significant. Evaluation mean comparison result of interaction effect of treatments indicated the maximum amount of seed yield (545.7 gr.m-2), protein content (15.75%), protein yield (120.8 gr.m-2), Oil content (9.44%) and Oil yield (51.69 gr.m-2) were for 10 t.ha-1 vermicompost with 0.006 L.ha-1 iron Nano fertilizer, also lowest amount of measured traits was for nonuse of vermicompost and iron Nano fertilizer (control) treatments. CONCLUSION: Generally according result of current research the maximum amount of seed yield, protein and oil content and protein and oil yield belonged to use 10 t.ha-1 vermicompost with 0.006 L.ha-1 iron Nano fertilizer.
