摘要：

A field experiment was conducted to study the time of seeding and method of herbicide application on pre-monsoon sown semi-dry 'PMK 1' rice (Oryza sativa L.) during winter (rabi) season of 1992-93 and 1995-94. Seeding of semi-day rice, a week before onset of monsoon significantly resulted in the maximum grain yield of 1,956 kg/ha. Among the methods of herbicide applications, pendimethalin @ 1.0 kg a.i./ha as pre-solving sand mixed, significantly registered higher grain yield of 2,151 kg/ha through effective reduction of weeds weeds and weed dry matter that resulted in better seedling growth and productive tillers.
