Abstract:

Influence of weed control practices on growth and yield of September planted maize (Zea mays L.) was studied in a field trial at the experimental station of Agronomy, UAF, Faisalabad, Pakistan. Experiment comprised of eight treatments, viz., weedy check (control), manual hoeing, bentazon @ 720, 840, 960, 1080 and 1200 g ha-1, (as post-emergence), and pendimethalin @ 1031 g ha-1 (as pre-emergence). All the weed control practices decreased weed density by 46-93%, weeds fresh weight by 39-98% and weeds dry weight by 42-88%. The highest grain yield was obtained with manual hoeing followed by the treatment with pendimethalin. Higher doses of bentazon were found inefficient to control weeds, however; it showed satisfactory results @ 960 g ha-1.
