PRODUTIVIDADE E SANIDADE DO CAPIM-MOMBAÇA FERTIRRIGADO COM ÁGUA RESIDUÁRIA DE LATICÍNIO

Abstract

In order to evaluate the yield and microbiological quality of Mombasa grass fertigated with dairy wastewater (LRL), the seeds of mombaça grass were sown, and after germination and leveling at 110 days after sowing (DAS). proceeded to fertigation with different doses based on the amount of sodium in the effluent. The treatments consisted of a control (without application of wastewater) and using doses of (ARL): T1: 75; T2- 150, T3- 300 and T4- 600 kg there is 1 day-1 sodium by application using watering cans, performed at three biweekly intervals. The grasses were subjected to analysis of total coliforms and thermotolerant coliforms after effluent application, and at the end of the experimental period plants were cut to obtain the yield of mombaça grass. The results allowed to conclude that the fertigation with ARL produced grasses of excellent sanitary quality, that is, without absence of thermotolerant coliforms. Regarding productivity, the input of effluent to the soil at a dosage of 600 mg L-1 of sodium resulted in the highest yield values. From increases in dairy wastewater, there was an increase in fresh mass and mass. drought of Mombasa grass.
