abstract
Seven plant powders viz. neem (Azadirachta indica J.), Camphor (Cinnamomum camphora L.), sweet flag (Acorus calamus L.), lemongrass (Cymbopogon citratus L.), eucalyptus (Eucalyptus sp.), wild marigold (Tegetes minuta L.) and drek (Melia azadirachta L.) were used to coat the seeds @ 5, 3, and 1g /100g seeds. There eight treatments including control. Minimum seed damage (0.33%) and weight loss (0.22%) was recorded with sweetflag plant powders. No seed damage and weight loss was recorded in pea seeds treated with sweet flag powder at 3g/100g and 5g/100g doses. Maximum seed germination was in sweet flag plant powder (93.67%). Maximum seed vigour index-I (2042.68) and seed vigour index-II (3481.67) was with sweet flag plant powder followed by neem. Thus, sweetflag (Acorus calamus L.) plant powder was best in protecting pea seeds against C. chinensis.
