Field study was carried out at Agricultural Research Station, SKRAU, Bikaner on sandy soil during rabi season of 2015-16 to 2017-18. Treatments comprises namely T1 – 100 % Seed rate Oats (100 kg/ha), T2 – 100 % Seed rate lucerne (20 kg/ha), T3 – T2 + Oats 10 kg/ha, T4 – T2+ Oats 20 kg/ha, T5 – T2+ Oats 30 kg/ha T6 – T2+40 Oats kg/ha, T7 – T2 + Sarson 0.625 kg/ha, T8 – T2 + Sarson 1.250 kg/ha, T9 – T2+1.880 kg/ha and T10 – T2 + Sarson 2.500 kg/ha in randomized block design with three replications. lucerne + Oat seed mixed treatments (T5) gave higher GFY and DMY as compared to remaining treatments like lucerne + sarson seed mixed treatments and sole lucerne & oat crop. Further data indicated that lucerne + sarson mixed crop treatments recorded higher GFY (except T7), but the variation in GFY was statistically non significant. The highest DMY (129.8 q/ha) was recorded in Lucerne + oat mixed with 30 kg/ha (T5). The highest CP % was noted in sole lucerne (T2) followed by lucerne + sarson mixed at 0.625 kg/ha (T7) and both these treatment found significantly superior over rest treatments. The maximum net return and B:C ratio found in sole oat (T1) was at par in lucerne + oat mixed @ 30 kg/ha (T5) and both treatments showed statistically superiority over rest treatments. However, oat sole crop gave four cuts and lasts fodder production up to mid April while lucerne + oat mixed treatment (T5) gave six cuts and lasts fodder production up to mid June.
