Quality, yield and economics of oat (Avena sativa L.) Genotypes for fodder under different nitrogen levels

Abstract

A two factor field experiment of eleven single-cut oat genotypes and three nitrogen levels was conducted in split plot design at Forage Section Research Farm, CCS Haryana Agricultural University, Hisar during rabi, 2016-17. Oat genotypes OS 424, OL-1769-1, OL-1802, SKO-225, JO-04-19, UPO-10-3, OL-1766-1 and OS-432 were compared with three checks (OS-6, Kent and OL-125). The nitrogen levels were 40, 80 and 120 kg per hectare. OL-1802 was superior for green fodder, dry matter and crude protein yield (754.6, 139.7 and 11.2 q/ha, respectively). Number of tillers/m row length, plant height, green fodder, dry matter yield, CPY and DDM were influenced with increasing nitrogen levels. Among genotypes, maximum net returns (Rs. 66257/ha) and B: C ratio (3.36) were fetched in OL-1802, whereas the application of 120 kg nitrogen/ha realized the maximum net returns (Rs. 48341/ha) and B:C ratio (2.69).
