Studies on disease dynamics of redgram and maize in conservation agriculture ecosystem

Conservation Agriculture (CA), defined as minimal soil disturbance (no-till) and permanent soil cover (mulch) combined with rotations, as a more sustainable cultivation system for the future. Red gram diseases such as wilt, dry root rot and Cercospora leaf spot and in maize crop, blight and Curvularia leaf spot were assessed by recording per cent incidence, severity and per cent disease index at monthly interval from Conservation Agriculture plot in different treatment such as Zero Tillage With Mulch (ZTWM), Zero Tillage Without Mulch (ZTWTM), raised bed with mulch (RBWM), Raised Bed Without Mulch (RBWTM) and farmers practice (FP). The lowest per cent disease severity of red gram wilt was recorded in the treatment ZTWTM (12.54%), whereas minimum per cent disease index of Cercospora leaf spot was observed in RBWTM treatment (10.88%), dry root rot was less in the treatment ZTWTM (22.19) while in maize minimum blight severity was recorded in the treatment ZTWTM (18.30%) and minimum incidence of Curvularia leaf spot was recorded in the treatment ZTWTM (11.94%) respectively and wilt, Cercospora leaf spot, dry root rot, blight and Curvularia leaf spot disease incidence in redgram and maize were more in farmers practice treatment (21.66,21.94,29.86,31.13 and 17.43%) respectively.
