ABSTRACT.
To reduce Fusarium Basal Rot caused by Fusarium oxysporum f.sp. cepae (Foc) through crop rotation, plant species should be selected based on Foc multiplication in their roots. Foc multiplication rates in 13 plant species were tested in a greenhouse. All plant species enabled Foc multiplication. The lowest Foc levels (cfu g−1 dry root) were found for wheat, sunflower, cowpea and millet, the highest for black bean. The highest Foc levels per plant were calculated for sudan grass. These data were used to calibrate the model Pf=Pi/(α+βPi) relating final (Pf) and initial (Pi) Foc levels in the soil. The rate of population increase at low Pi (1/α) was highest for onion and black oat and smallest for sunflower. The pathogen carrying capacity (1/β) was highest for black oat and black bean, and lowest forwheat, cowpea and foxtail millet. Foc soil population dynamics was simulated for crop sequences by concatenating Pi-Pf values, considering instantaneous or gradual pathogen release after harvest. Different soil Foc populations were attained after reaching steady states. Foc populations in the sequence onion ?foxtail millet - wheat ? cowpea were 67 % lower than in the sequence onion ? sudan grass - black oat - black beans. In this work, by combining detailed greenhouse experiments with modelling, we were able to screen crops for their ability to increase Foc population and to explore potential crop sequences that may limit pathogen build-up.

La nueva variedad tropical INIA Olimar se ha destacado a nivel experimental por su elevado potencial de rendimiento, estabilidad, precocidad y muy baja incidencia de granos yesados. En la Zafra pasada se sembró por primera vez un área significativa de esta variedad, constituida fundamentalmente por semilleros, alcanzando aproximadamente 3.000 hás. La disponibilidad de semilla producida permitiría un crecimiento importante de INIA Olimar, en caso de que el sector decida su adopción, por lo que es oportuno revisar sus características y el comportamiento en cultivos en la zafra 2003/04, la cual tuvo características climáticas particulares que permitieron que el país alcanzara un nuevo record de rendimiento. |
