DESEMPENHO AGRONÔMICO E SANITÁRIO DE SEMENTES DE AVEIAS FORRAGEIRAS

Abstract

Brazil is considered a leader in the production of beef and dairy cattle, pig farming and poultry farming, in addition, it expresses productive potential in goat and sheep herds. Therefore, it is important to carry out studies to enhance the quality of nutrition for these herds, in addition to encouraging adequate management of forage crops. Associated with the need for a high food supply are plants of the Avena genus, which can be considered as an alternative when it comes to forage production. In view of the above, the present work aims to evaluate the behavior of black oat (Avena strigosa) and white oat (Avena sativa) cultivation, originating from saved and certified seeds, in the production of biomass and dry matter, in addition to comparing the quality of these origins. To this end, a laboratory test was carried out in a completely randomized design (DIC), in order to evaluate qualitative parameters of the seeds, which were subsequently evaluated in the field using a randomized block design (DBC) to observe quantitative parameters through cuts simulating the grazing. Both, distributed in a 2 x 2 factorial scheme (two varieties of black and white oats, in two different qualities), these being the saved and certified Ukrainian cultivar and cultivar 139, also in both origins. The variables evaluated were: germination potential, vigor, embryonic viability, seed health, production of green and dry mass. This forage has high palatability and adaptability and high nutritional value, as well as different forms of use, and can be considered an important ally in human and animal nutrition. It is possible to observe the positive influence of the use of certified oat seeds, as, in the tests carried out, it is noted that in treatments from these sources there is greater sanitary and physiological quality, as well as greater forage production.
