Abstract
The field experiments were conducted at the Main Agricultural Research Station, Dharwad
during Rabi 2012 and 2013 and storage studies conducted during 2014 in the laboratory of
Department of Seed Science and Technology during 2013-2014 at College of Agricultural Sciences,
Dharwad. Results revealed that application of nitrogen @ 140 kg/ha was recorded significantly higher
green fodder yield (122.22 q/ha) and among the cutting management two cut recorded higher green
fodder yield (229.39 q/ha). Among the cutting management no cut treatment recorded higher seed
yield (7.61 q/ha) and among nitrogen management (6.99 q/ha) was recorded in nitrogen 140 kg/ha
recorded higher seed yield, due to interaction (7.81 q/ha) was recorded in treatment combination of
no cut with 140 kg N/ha. For the same factors seed quality parameters was also maximum, among
the cutting management no cut recorded higher seed germination (94.13%), vigour index (2426) and
among nitrogen management 140 kg N/ha recorded higher seed germination (93.38%) and vigour
(2304), due to interaction no cut with 140 kg N/ha recorded higher seed germination (94.75%) and
vigour index (2797) in oat cv. JHO-851. Seed quality parameters found higher when the seeds are
harvested at 45 days after anthesis higher seed germination (92.75%) and vigour (2821) in oat cv.OS-
6. Among organics, application of Vermicompost @ 5t/ha was found higher plant growth, seed yield
and seed germination (95.44%), vigour index (2776) and with micronutrients Zinc sulphate @ 15
kg/ha was found higher plant growth, seed yield and quality parameters like seed germination
(94.88%), vigour index (2620) in oat cv.OS-6. The seeds of oat stored in polythene bag (700 gauge)
treated with vitavax+deltamythrin followed by vitavax, deltamythrin, arappu, neem, sweet flag powder
storage upto fifteen month with loss of lesser seed quality parameters in oat cv. OS-6.
