The results of the field experiment conducted at Lucknow from 1994 to 1996 revealed that varying levels of irrigation and nitrogen as well as different weed control measures significantly affected the weed growth and the yield attributes and yield of sugarcane (Saccharvm officinarvm L.). The highest cane yield (77.1 tomes/ ha) was obtained with atrazine + 2,4-D + 1 hoeing treatment, however, the benefit : cost ratio (1.69) was highest with the use of chemicals alone. Juice quality remained unaffected due to various treatments. Significant increase in nitrate reductase activity due to weed control measures was also observed. Atrazine persisted in soil varying from 45 to 60 days and its content declined with increasing A- moisture and nitrogen levels.References
