This work aimed to provide zonal results regarding the contributions of CC on resource use effi ciency and sunfl ower productivity. During 2017 and 2018, six CCs as sunfl ower predecessors in Coronel Suárez (Southwest of Buenos Aires) were tested. Soil water and dry matter, nitrogen and vegetable yield were evaluated. The difference in edaphic water content upon drying of the CC with respect to the conventional fallow (BC) varied between -8 and 15 mm. The water use effi ciency (EUA) ranged from 5.59 kg MS mm -1 in vetch (V 1 ) and 16.16 kg MS mm -1 in oats (A). The highest yields were obtained with V 1 (2379 kg ha -1 ) and the lowest with A (1561 kg ha -1 ) Los cultivos de cobertura (CC) se utilizan tradicionalmente para controlar problemas de erosión, mejorar la captación, distribución y almacenaje de agua, reducir la compactación, mejorar los balances de carbono y nitrógeno del suelo. Este trabajo pretendió aportar resultados zonales en cuanto a las contribuciones de CC sobre efi ciencia de uso de los recursos y productividad del girasol. Durante 2017 y 2018 se ensayaron en Coronel Suárez (Sudoeste de Buenos Aires) seis CC como antecesores de girasol. Se evaluaron: agua en el suelo, materia seca, nitrógeno y rendimiento.La diferencia en el contenido de agua edáfi ca al secado de los CC respecto al barbecho conven-cional (BC) varió entre -8 y 15 mm. Las efi ciencias de uso de agua (EUA) con respecto al testigo, oscilaron entre 5,59 kg MS mm -1 en vicia (V 1 ) y de 16,16 kg MS mm -1 en avena (A). Los mayores rendimientos de girasol se obtuvieron con V 1 (2379 kg ha -1 ) y los menores con A (1561 kg ha -1 ).
