Papel del fósforo y del cobre sobre el crecimiento y composición del café Arábica cultivado en arena
Non-flowering two-year old Coffea arabica L. (cv.'S.L 34') plants were grown in sand culture and treated with varying combinations of copper and phosphorus. Increases in the number of leaves and flower buds were observed at P levels of 90 to 140 ppm in the presence of Cu levels of 1064 and...
