BACKGROUND: Addition of fertilizers to supplement the natural soil fertility is essential for modern crop production, and precise management of nutrient elements is essential for a sustainable agriculture production. OBJECTIVES: The current research was conducted to assessment effect of different level of Methanol and Zinc fertilizer on seed yield and its components of Cowpea. METHODS: This study was carried out according Factorial experiment based on randomized complete blocks design with three replications along 2018 year. The test factors consisted of different levels of Methanol in distilled water at three levels (a1: the absence of methanol or control, a2: 10% Vol., a3: 20% Vol.) and zinc fertilizer (b1: the lack of zinc or control, b2: 2 per thousand, b3: 4 per thousand). RESULT: According result of analysis of variance effect of different level of Methanol and zinc fertilizer and interaction effect of treatments (number of pods per plant, number of seeds per pod, seed weight and harvest index) on all studied traits were significant. Among different level of Methanol the maximum amount of number of pods per m2 (117.45), number of pods per plant (14.42), number of seeds per pod (11.4), seed weight (23.04 gr), seed yield (218.08 gr.m-2), biologic yield (522.33 gr.m-2) and harvest index (41.75%) was obtained for 20% Vol. Methanol and the minimum of mentioned traits were for control treatment. Assessment mean comparison result of different level of zinc fertilizer showed the highest amount of measured traits belonged to 4 per thousand concentration (also it doesn’t have significant differences with 2 per thousand) and lowest ones was for control. CONCLUSION: Finally according result of current research application 20%vol. Methanol and 2 per thousand concentrations Zinc Chelate had the highest amount of studied traits and it can be advice to producers in studied region.
