Impact of cutting and splitting of nitrogen doses on growth, yield and quality of fodder oat

Abstract

A field experiment was conducted at Forage research field under All India Coordinated Research Project on (Forage Crops & Utilization) situated at College of veterinary science and Animal Husbandry, Kanke Ranchi (Jharkhand) to evaluate the effect of cutting and splitting of nitrogen levels on oat. Pooled of three years data showed that, the oat variety RO-19 recorded more plant height (104.58 cm), GFY (461.12 q ha-1), DFY (90.91 q ha-1), crude protein content (5.93), crude protein yield (5.38), crude fiber (46.25%), IVDMD (60.55%), Gross return (Rs 69,168 only), net return (Rs. 43,483 only) and B:C ratio (2.71).While among the cutting and nitrogen management three cuts + 50% Basal + 25% at 1st cut + 25% at 2nd cut recorded some marginal better tillers per meter row length (111.78), green fodder yield (437.0 q ha-1), DFY (85.91 q ha-1) crude fiber (47.45%), crude fat (5.90%),.With regards to economic Variety RO-19 with Two cut + 50% Basal+50% at 1st cut recorded better than other variety JHO-85 and UPO-212 with different combinations of cutting and nutrient management.
