ABSTRACT
An experiment to study the performance of weeds in maize crop against different
tillage and weed control methods was conducted at Agronomy Research Farm, The
University of Agriculture Peshawar during summer 2016. Field experiment was conducted in
randomized complete block design (RCBD) with split plot arrangement having four
replications. Tillage practices i.e. chisel plough + rotavator, mouldboard plough + rotavator,
cultivator + rotavator and rotavator were assigned to main plots. Weeds management
practices include control, hoeing 15 days after sowing, hoeing 15 and 30 days after sowing,
hoeing 15, 30 and 45 days after sowing, and herbicide (Nicosulfuron) were kept in subplots.
The results revealed that chisel plough + rotavator significantly reduced weeds m-2 (122,
101 and 125 weeds m-2), weeds fresh weight (19.73 g m-2, 116.35 g m-2 and 252.56 g m-2)
and weeds dry weight (6.83 g m-2, 38.69 g m-2 and 80.61 g m-2) at 30, 45 and 60 days
after sowing, respectively. The operation of chisel plough + rotavator produced tallest plants
(221.22 cm) with maximum grain rows ear-1 (16) and shelling percentage (78.14%).
Among weed control methods, hoeing 15, 30 and 45 days after sowing showed maximum
plant height (226.41 cm), grain rows ear-1 (16), and shelling percentage (79.11%). All weed
control methods showed significant reduction in weeds m-2, weeds fresh
