EFFECT OF CUTTING AND NITROGEN MANAGEMENT ON PLANT MATURITY AND SEED SET IN OAT CV. JHO-851(AVENA SATIVA L.)

Abstract

The field experiment was carried out at UAS, Dharwad, in the department of Seed Science and Technology
during Rabi season of 2012 and 2013for 2 year with the following treatments N1
: 80 kg/ha, N2: 100kg/ha, N3:
120kg/ha, N4: 140kg/ha. Cutting management: C1
: No cut, C2
: one cut, C3
: two cut and for all treatments 60:40

with no cut and 140kgN/ha showed significantly higher seed quality parameters.
