Fish farming effluent application in the development and growth of maize and bean plants

Abstract

The irrational use of water resources in Brazil has been causing concern to all sectors of society, including agriculture, which demands large amounts of water for its development. Thus, reuse of fish farming effluent is a viable alternative since it can be beneficial to plants. Therefore, the objective of this work was to evaluate the effect of fish farming effluent on the growth and development of maize and bean plants. Two water types (reservoir water and fish farming effluent) were evaluated using a completely randomized design with ten replications. At 50 days after sowing, the following were evaluated: plant height, root length, plant collar diameter, fresh matter of shoots, and dry matter of shoots and roots of maize and bean plants. Fish farming effluent application significantly influenced the development and growth of maize plants. For bean plants, the fish farming effluent did not influence their development and growth.
