BACKGROUND: Mineral fertilizers played a great role towards improving crop yields but main constraint in achieving proven crop potential is imbalanced use of fertilizers, particularly low use of microelements like copper as compared to N.OBJECTIVES: This research was consisted to determine effect of different concentration and stage of foliar application of Copper on qualitative traits of Cowpea.METHODS: This research was carried out via factorial experiment based on randomized complete blocks design with three replications along 2017 year. The treatments included different concentration of Copper foliar application (a1: none use of copper or control, a2: 150 gr.ha-1, a3: 300 gr.ha-1, a4: 450 gr.ha-1) and Copper foliar application at different growth stage (b1: apply at vegetative stage, b2: beginning of flowering stage, b3: beginning of pod formation).RESULT: According result of analysis of variance effect of different concentration and growth stage of foliar application of Copper (instead copper percentage) on all measured traits was significant but interaction effect of treatments was not significant (instead seed yield). Evaluation mean comparison result revealed the maximum plant height (157.14 cm), seed yield (211.61 gr.m-2), protein percentage (31.56%), protein yield (66.59 gr.m-2) and Copper percentage (21.29%) was noted for 300 gr.ha-1 Copper (Also it doesn’t have significant difference with 150 gr.ha-1 Copper) and minimum of mentioned traits belonged to control treatment. Between different growths stage of foliar application of Copper the maximum amount of studied characteristics was observed in vegetative stage and the lowest ones was found in beginning of pod formation.CONCLUSION: It is recommended to farmers due to compliance with environmental aspects and less consumption of chemical inputs to use 150 gr.ha-1 of copper foliar application in the vegetative stage.
