PERFORMANCE O}<'CAPSULARIS JUTE (Corchorus capsularis) VARIETIES IN RELATION TO SEED YIELD AND DISEASE INCIDENCE GROWN IN LATE SEASON

Abstract

An investigation was conducted to find out the performance of deshi jute (Corchorus capsularis L) varieties in late season seed production method and incidence of diseases in late season seed crop. Five varieties of commonly cultivated in Bangladesh were used. They were CVL-I. CVE-3. BJC-2142, BJC7370 and BJC-45. Five fungal diseases viz. stem rot (Macrophomina phaseolinas, black band iBotryodiplodia theobromei, anthracnose (Cotletotrichum corchoris, die back (Gloeosporium sp.) and wilt iRhizoctnia so/ani) were identified in capsularis jute varieties in late season seed crop. Variation among varieties was observed in terms of disease incidence and seed production. The most prevalent disease was stem rot followed by anthracnose and wilt. Disease incidence was lower in varieties eVE-3 and eVL-1 and they gave higher seed yield compared to other varieties. The seed yield was 608.3 kg/ha in eVE-3 and 582.22 kg/ha in CVI.-I.
