SUMMARY

A two factor field experiment was conducted during rabi 2014-15 at CCS HAU, Hisar, Haryana to study the response of new malt barley (Hordeum vulgare L.) genotypes to different nitrogen levels under irrigated and timely sown conditions. The highest grain yield was recorded at 120 kg N/ha (46.8q/ ha), which was significantly higher than 60 kg N/ha (42.3 q/ha). The highest number of effective tillers/ m2 (446) was recorded at 120 kg N/ha, which was significantly higher than 60 kg N/ha (422) but statistically at par with 90 kg N/ha (443). Among N levels, maximum straw yield (74.7 q/ha) was recorded with 120 kg N/ha followed by 90 kg N/ha. Among genotypes, PL-874 produced highest grain yield (48.8 q/ha), which was significantly higher than other genotypes except BH-976 (47.3 q/ha). The maximum number of effective tillers/m2 (476) was observed in DWRB-92, whereas maximum grains/earhead were recorded in BH-902, which was significantly higher than other genotypes. Among genotypes, maximum harvest index was recorded in RD-2849 (39.3) followed by DWRB-101.
