ABSTRACT
A field experiment was carried out during Kharif 1999 at experimental farm of CSK HPKV Palampur to check the sensitivity of newly released varieties to herbicides in direct seeded puddled rice. Experiment was conducted in randomized block design with nine treatment combinations each replicated thrice. Treatments consisted of combinations of three-weed control methods viz., two hand weeding, butachlor 2.0 kg/ha and pretilachlor 0.8 kg/ha and three rice varieties RP-2421, HPR-957 and HPR-927. It can be concluded from the study that HPR-957 was sensitive to butachlor 2.0 kg/ha and pretilachlor 0.8 kg/ha herbicides.
