| dc.description.abstract | An experiment was conducted at the Instructional Farm of the College of Agriculture, Vellayani, Kerala Agriculture University during the second crop season, 1976-77 to study the critical periods of used infestation and effect of weed growth on the yield and quality of a duration rice ver. Triveni Simple randomised block design was adopted with 17 treatments. Band weeding was done to keep weed free conditions of 10,20 and 30 day intervals upto 60th day and for 1-60 days after transplanting. The above weed free periods with one unweeded control formed the 17 treatments. | en_US |
