Produtividade do capim mombaça irrigado e sobressemeado com aveia

Abstract

The objective of this work was to evaluate the productivity of the Mombaça (Panicum maximum) grass managed with and without irrigation, exclusive or overestimated with forage oats. The production of fresh (natural) matter and dry matter during the analyzes were determined. The experiment was conducted in the experimental area of the Federal University of Grande Dourados located in the municipality of Dourados-MS with latitude 14 '16 "S, longitude 54 ̊ 49' 20" W and altitude of 450 meters. Dystroferric Red Latosol. The experiment was carried out from February to November 2018, aiming the implantation of the Avena sativa (Oat) crop on Panicum maximum (Mombaça grass). The experimental area was composed of four pickets with dimensions 15 by 15 m each, totaling an area of 900 m2, consisting of irrigation in two of the pickets. All the plots were demolded with costal trimmer after the 17th day of oat planting, being considered as day zero (D0). Days D1 and D2 were 40 and 80 days after D0, respectively. On days D0, D1 and D2, forage samples were collected for the determination of green matter and dry matter. The inclusion of forage oats and irrigation in the experiment was aimed at reducing seasonality, which occurs in the winter period, and impairs pasture growth.
