SUMMARY
Sixteen genotypes of barley and eight genotypes of oat were evaluated for green fodder and seed yield during rabi 2012-13 at Agricultural Research Station, Keshwana, Jalore (Rajasthan). Green fodder yield of oat genotypes ranged between 56.00 and 130.33 q/ha with the average of 94.28 q/ha; however, in barley it varied between 119.50 and 238.50 q/ha with the average of 178.70 q/ha at 53 days after sowing. The seed yield of regenerated oat varied between 6.98 and 20.57 q/ha with the average yield of 14.50 q/ha; and in barley it ranged between 19.79 and 47.43 q/ha with the average of 31.29 q/ha. This high degree of variability among genotypes of oat and barley revealed a good scope of selection. Genotypes OS-387, JO-09-504, JHO-2012-5, JHO-822 and UPO-212 of oat and RD-2035, BH-971, Azad, UPB-1035, UPB-1036, UPB-1034, RD-2715 and RD-2552 of barley appeared relatively better for green fodder and seed yield in dual purpose cultivation. Relative performance of these two species revealed that plant height and green fodder yield of fresh crop and seed yield of regenerated crop were higher in barley; however, plant height and biological yield of regenerated crop were found higher in oat. Total income received from green fodder, seed and straw yield of barley was Rs. 104262.00/ha, whereas it was Rs. 81710.00 in oat. Therefore, cultivation of dual purpose barley was found more profitable than oat in arid Rajasthan.
