Field tr’-als were conducted in rabi 1974–75 and 1975–76 to determine the stimulatory effects of sub-lethal doses of simazine on forage production in a diploid variety of berseem (Tri/olium resupinatum). In these experiments simazine (2-chlora-4, 6-bis (ethylamino)-S-triazine) was applied at 0.25, 0.125 and 0.0G2 kg/ha before and after the first out of fodder. In another treatment a repeat application of simazine at 0.125 kg/ha after the first and second cuts was included. Immediately after simazine appplication, a light irrigation was given to leach the chemical for absorption by berseem roots.
In both the years the green fodder production was significantly enhanced by a single application of simazine at 0.062 kg/ha after the first cut. Substantial enhancement also occured at 0.125 and 0.062 kg/ha simazine application before the first cut.
