Effect Of Irrigation Using Water From Fish Ponds On Plant Growth In Northeastern Nigeria

ABSTRACT The irrational consumption of water is one of the greatest problem in the world today. Irrigation of agricultural crops with fish effluent is one way to solve this problem. Rather than disposing of effluents gotten from aquaculture; then providing nutrients from fertilizer and irrigation from another source of water. We could use water containing fish effluent to irrigate agricultural crop. The aim of this study was to determine the effect of irrigating with water from fish ponds on...
