Abstract
Experiments were conducted on chilli varieties Dyavanoor local and
Byadagi kaddi at the main research station, Univeisity of Agricultural Sciences,
Dharwad during kharif 1996 to investigate the effect of fungicidal sprays on field
performance, fruit yield and seed quality. In the laboratory, effect of containers,
seed dressing fungicides and methods of storage on seed storability were looked
into.
The chilli varieties exhibited significant differences in dieback and fruit rot
incidence. Dyavanoor local sprayed t^vice with Chlorothalonil 0.1 per cent at 15
days interval showed low incidence of die back and fruit rot incidence while
Byadagi kaddi produced higher fruit yields.
Seed quality parameters such as 100 seed weight, germination, shoot and
root length, seedling diy weight, vigour and field emergence were highest in the
variety Byadagi kaddi sprayed twice with Chlorothalonil coupled with the Suit
picked at 145 days after planting. With respect to storability over a period of six
months, there was a fair degree of preservation of seed quality in seeds treated with
Captan 2g per kg and stored in polythene bag. However, irrespective of fungicides,
containers and methods of storage, the seed quality of both the varieties dccreased
while fungal colonization increased with the increased period of storage. The
highest quality was realized from the seeds of variety Byadagi kaddi which were
stored as fruits in polythene bag.
