Influence of growing sweet pepper in compacted rice straw bales compared with natural soil, on infection with pathogenic fungi and nematodes under Greenhouse conditions [electronic resource].

Includes reference.

Rice straw bales could be used as a growing media for cultivation of vegetable crops instead of soil. The present study, which is considered the first in this respect in Egypt, aimed to evaluate the effect of using rice straw bales as a medium for cultivation of pepper on the disease infection by root pathogens. The cultivation of sweet pepper seedling cv.4408 F1 hybrid on rice straw bales was carried out in two locations: in EI-Ismailia Governorate (Abo-Swear and EI-Ferdan Districts), under plastic net greenhouse conditions during 7-10 May. 2007. In the first location, Abo-Swear, the disease Incidence of root rot, wilt and root knot nematodes in sweet pepper plants grown in rice straw bales reached 1.1, 0.85 and 0.0% respectively. However, the corresponding figures for sweet pepper plants grown in natural soil under the same conditions were 14.8, 21.9 and 33.2%, respectively.The same trend was observed in the second location EI-Ferdan district. Determination of pathogenic nematodes in rice straw bales and natural soli revealed the presence of 80 Juvenile (J2) of Meloidogyne spp. and 120 juvenile (J2) of Tylenchorhynchus sp. per 250 g natural soil.
