WEGNER KUNZ, Douglas et al. Agronomic performance of black oats conducted with haul and in-line sowing. Investig. Agrar. [online]. 2023, vol.25, n.2, pp.88-92. ISSN 2305-0683.  https://doi.org/10.18004/investig.agrar.2023.diciembre.2502782.

The black oats (Avena strigosa S.) is an excellent forage plant, besides acting in the system of rotation and succession of cultures. In recent decades, oat genetic improvement programs have worked intensively to select materials that are more responsive to pests and diseases, in addition to seeking greater mass and grain productivity. However, these new materials need to be tested for agronomic performance in different seeding systems. Given the importance of culture, the objective of this work was to evaluate the agronomic performance of black oats conducted with two sowing methods. The treatments were arranged in blocks at random in a 2x2 factorial arrangement, that is, two sowing methods (at haul and row) and two cultivars (UPFA 21 - Moreninha and EMBRAPA 139), with five replications, in a useful area of ​​7.15 m2 per plot. Sixty days after sowing, the cultivars were evaluated for height, total fresh phytomass production (TFF) and total dry phytomass (TDP). The results indicated statistically significant differences in the production of TFF and TDP between cultivars and between sowing methods, being the cultivar UPFA 21 - Moreninha more productive, in addition to presenting better results in the sowing system in line. There were no significant differences in plant height between the treatments evaluated. However, sowing in line allowed greater production of TFF and TDP for the cultivar UPFA 21 - Moreninha.
