Field study was carried out at Instructional Dairy Farm, Nagla, G. B. Pant University of Agriculture and Technology, Pantnagar in the Rabi season of 2021-22 to evaluate the ‘Effect of nano urea scheduling on productivity, profitability and residual fertility of multi cut fodder oat (Avena sativa L.)’. Nano urea scheduling had significant effect on productivity, profitability and residual soil fertility of multicut fodder oat. The results showed that application of 125% RDN (75 kg N basal followed by top dressing of 37.5 kg N each at 1st and 2nd cut) had significantly higher green and dry forage yield and also net return with 6.9, 6.6 and 10.3% higher green fodder yield, 8.1, 7.2 and 11.1% higher dry fodder yield and 10.2, 8.5 and 16.8% higher, respectively than 125% RDN + NU, 100% RDN and 100% RDN + NU treatments. Among the vermicompost treatments, the green fodder yield was 3.1 and 3.3% and dry fodder yield was 3.8 and 2.2% higher under 75%RDNVC + NU than 100% RDNVC and 50% RDNVC + NU, respectively. The B:C ratio was higher under 75% RDNVC + NU than 100% RDNVC. The residual available N, P and K were also found higher at 125 RDN that was at par with 100% RDN. Therefore it is concluded that multicut oat may be grown with application of 100% RDN i.e. 120:60:40 ::N:P205:K20 kg/ha and for organic oat fodder, vermicompost may be applied @4.5 t/ha as basal followed by two spay with nano urea @ 4ml/l at 1st and 2nd cut for higher productivity, profitability and sustainability in Tarai region of Northern Himalaya and may also be replicated in whole northern-Western regions of India.
