Abstract:

Organic soil amendments are used routinely in various aspects of crop production and reported to either increase or decrease the incidence of plant diseases. Certain plant families when used as amendments were reported to suppress certain diseases through biofumigation. Based on this premise, a trial had been conducted to determine the effect of fresh cabbage residues, Chromolaena odorata and forest leaf litter as soil amendments on disease incidence, severity and yield of tomato grown under low-cost protective structure and open field. All three amendments were applied at the rate of 15 kg/10 m2 plots, 3 weeks before transplanting. Data gathered include disease ratings and yield and yield components. Results showed that all amendments have reduced bacterial wilt due to Ralstonia solanacearum and Meloidogyne incognita galls regardless of type of cultivation. Plants amended with Chromoalena odorata and forest leaf litter had also reduced bacterial spot caused by Xanthomonas axonopodis pv. vesicatoria under protective cultivation. The amendments had no effect on the incidence of leaf mold due to Pseudocercospora fuligena. Cabbage produced the highest marketable yield and number of fruits in both protective and open field cultivation compared to other treatments. Protective cultivation on the other hand had effectively reduced bacterial diseases and increased the yield of tomato. Bacterial wilt, bacterial spot and nematode ratings were higher in the open field while leaf mold was higher under protective cultivation. Organic amendments, particularly cabbage has a potential in the control of major diseases affecting tomato especially for bacterial wilt and M. incognita infestations.
