YIELD AND QUALITY OF POTATO AS INFLUENCED BY WEED MANAGEMENT PRACTICES AND THEIR RESIDUAL STUDY IN SOIL
effect of weed management practices on yield and quality of potato. Lowest weed biomass at
harvest was found in prometryne (0.1 kg/ha PE) treated plots, followed by pendimethalin (1.0
Kg/ha PE) and metribuzin (0.5 kg/ha PE). Similarly highest yield of potato tubers was recorded
in plots treated with prometryne (0.1 kg/ha PE), next best treatments were pendimethalin (1.0
Kg/ha PE), metribuzin (0.5 kg/ha PE) and two hand weedings. Highest dry matter content of
potato tubers was recorded in fluchloralin followed by alachlor, one earthing .and mulching, all
being significantly superior to hand weeding treatment while higher dry matter yield was recorded
in prometryne (0.1 kg/ha PE), pendimethalin (1.0 Kg/ha PE) and metribuzin. Ascorbic acid content
was highest in pendimethalin treated tubers followed by fluchloralin and paraquat. Protein content
was highest in pendimethalin treated tubers followed by metribuzin and prometryne, while
maximum starch content was found in prometryne, followed by fluchloralin and mulching
treatments. No residual activity of herbicides applied to potato was found in post harvest soil.
