ABSTRACT
Maize diseases such as blight and Curvularia leaf spot were assessed by recording per cent incidence, severity and per cent disease index at monthly interval from conservation agriculture ecosystem. In maize, minimum blight severity was recorded in the treatment ZTWTM (18.30%) and maximum in farmers practice treatment (31.13%) while the minimum incidence of Curvularia leaf spot was recorded in the treatment ZTWTM (11.94%) and maximum incidence recorded in farmers practice treatment (17.43%). Similarly different temperatures are taken to record the radial growth and dry mycelial weight of Trichoderma spp. The radial growth of Trichoderma was maximum for all the four species i.e., T. harzianum, T. viride, T. hamatum and T. virens (90, 82, 91.3 and 85mm) at 30oC, where it was minimum in four species at 40oC (30.70, 35, 22.53 and 20mm) respectively and dry mycelia of T. harzianum (1.05 mg), T. viride (1.83 mg), T. hamatum (2.42 mg) & T. virens (0.82 mg).
Key words :
Conservation agriculture, Dry mycelia and temperature, Radial growth, Trichoderma spp.
