II - El control de la pudrición apical en los frutos del tomate (Lycopersicon esculentum L., variedad Rosso Mejorado INTA) y su efecto sobre la productividad de la papa (Solanum tuberosum L., variedad Claustar) Rossi Jaume, A. Tizio, R. horticultural plants potato plantas hortícolas patatas CaCl₂ 2000 ppm in a nutritive mineral solution of KH₂PO₄ 3000 ppm, K₂SO₄ 1500 ppm, H₃BO₃ 500 ppm, ZnSO₄ 500 ppm, MnSO₄·4H₂O 300 ppm, CuSO₄·5H₂O 50 ppm, Na₂MoO₄·2H₂O 14 ppm and Fe and Na EDTA 15 ml/l was sprayed on foliage of tomato plants cv Rosso Mejorado INTA on three occasions starting before blooming in the first cluster. The treatment yielded a highly significant decrease (at 0,001% level of significance) on fruits affected by blossom end rot. No significant differences were observed in the fresh weight of healthy fruits in relation to the control and the treatment with the nutrient solution deprived of Ca. This could be due to the fact that Ca diminishes the number of growing fruits in the first cluster. In potato, three foliar sprays of a nutrient solution containing urea 3000 ppm, K₂HPO₄ 3500 ppm, MgSO₄ 3000 ppm, KCl 1500 ppm, H₃BO₃ 1000 ppm, FeSO₄·7H₂O 1500 ppm, ZnSO₄ 500 ppm, Na₂MoO₄·2H₂O 100 ppm and CuSO₄·5H₂O 50 ppm, applied on young plants at intervals of 15 days produced a significant increase (at 5% level of significance) in yield only in the case of a previous edaphic fertilization based on a combination of (NH₄)₂HPO₄ and (NH₄)₂SO₄ 300 kg/ha each one. In this case, the increase in yield was due to a higher tuber weight. Aspersiones por vía foliar de CaCl₂ 2000 ppm acompañadas de una solución nutritiva compuesta de KH₂PO₄ 3000 ppm, MgSO₄ 3000 ppm, K₂SO₄ 1500 ppm, H₃BO₃ 500 ppm, ZnSO₄ 500 ppm, MnSO₄·4H₂O 300 ppm, CuSO₄·5H₂O 50 ppm, Na₂MoO₄·2H₂O 14 ppm y EDTA de Fe y Na 15 ml/l, aplicadas en tres oportunidades a partir del inicio de la apertura floral del primer racimo de tomate cv Rosso Mejorado INTA, producen una reducción altamente significativa (a nivel del 0,001%) en el número de frutos afectados por necrosis apical. No se observaron diferencias significativas en el rendimiento en peso fresco de frutos no afectados por la enfermedad en relación al testigo y a la variante solución nutritiva carente de Ca. Ello se debería a que el tratamiento con este catión produce un número significativamente menor de frutos cuajados en el primer racimo. En papa, tres aspersiones foliares de una solución nutritiva compuesta de urea 3000 ppm, K₂HPO₄ 3500 ppm, MgSO₄ 3000 ppm, KCl 1500 ppm, H₃BO₃ 1000 ppm, FeSO₄·7H₂O 1500 ppm, ZnSO₄ 500 ppm, Na₂MoO₄·2H₂O 100 ppm y CuSO₄·5H₂O 50 ppm, aplicadas sobre jóvenes plantas a intervalos de 15 días, produjeron un aumento significativo (a nivel del 5%) en los rendimientos del cv Claustar. Dichos aumentos sólo se produjeron si previamente las plantas se fertilizaron por vía edáfica con (NH₄)₂HPO₄ y (NH₄)₂SO₄ a razón de 300 kg/ha de cada fertilizante. Los aumentos en los rendimientos se debieron a un mayor tamaño de los tubérculos y no a un mayor número de los mismos.
