FERTIRRIGAÇÃO COM EFLUENTE DE LATICÍNIOS EM CAPIM MOMBAÇA

Abstract

With population growth and food demand, it results in an increase in waste, especially the dairy industry generates a large amount of waste, which in turn has components in its constitution that when disposed in inadequate quantities and places become environmental liabilities. In order to minimize impacts and properly dispose of these residues, this study aimed to carry out fertigation with dairy wastewater and evaluate the productivity and health of Mombasa grass. For this, providing different doses of sodium, the treatments consisted of applications of wastewater from dairy products in the culture of mombaça grass (fertigation), with four replications, in a completely randomized design. It was verified that the increments of doses of dairy wastewater provided an increase in the production of fresh mass and dry mass of Mombaça grass, and that the contribution of effluent to the soil at the dosage of 600 mg L-1 yr-1 of sodium resulted in the highest productivity values, with increases of 118.5% and 96.5% in fresh and dry matter, respectively.
