An abiotic stress such as low temperature or frost poses serious challenge for proper growth and development of the crop. The study was carried out for two consecutive years to investigate the effect of mixed cropping (berseem + oat vs pure berseem) and two bioregulators (H2SO4 and Thiourea) applied at different concentrations (0.05 and 0.1%) during low temperature conditions on growth, fodder yield and seed yield of berseem. Berseem + oat cropping recorded significantly higher green fodder yield, dry matter yield and crude protein yield by 7.0%, 6.1% and 3.4% respectively over pure stand. Bio-regulators sprays viz. H2SO4 and Thiourea after first cut recorded 5.2–11.2% increase in green fodder yield. Berseem seed yield and harvest index were significantly superior in pure stand than intercrops. An increase of 21.4% in berseem seed yield was recorded with foliar sprays of 0.05% TU over control.
