Abstract
Abstract This study was conducted, the effects of various weed control methods to suppress the growth and development of weeds for enhancing growth and yield of maize, at the experimental area of Agronomy section, Agriculture Research Institute, Tandojam, during winter season 2011-12. The experiment was comprised of five treatments viz; T1= Weedy check, T2= Hand hoeing, T3= Mechanical, T4= Cultural and T5= Chemical weed control in randomized complete block design (RCBD) with four replications. Different weed species were found in the experimental field viz; 1Chenopodium album L, 2Rumex dentatus L., 3Phalaris minor, 4Anagallis arvensis, 5Convolvulus arvensis, 6Chenopodium morale L, 7Cynodon dactylon, 8Cyperus rotundus. Results indicated that the Leaves plant-1, Cobs plant-1, Plant height (cm) and Grain yield kg ha-1 of maize were significant (p 0.05) in all treatments except weedy check. Hand hoeing weed control method effectively reduced weeds as compared to other weed control methods. On the other hand, when weeds frequency increased significantly decreased parameters of maize. It was concluded that the hand hoeing weed control method was found suitable and effective to suppress weeds and improved grain yield of hybrid maize crop as compare to other weed control methods.

Highlights
The grain yield kg ha-1 of maize is very low of Pakistan as compared to other corn growing countries such as, Italy, USA, Canada, Argentina and China
The statistical analysis of variance indicated that the all growth, and yield contributing parameters of maize such as, leaves plant-1, days to tasseling and silking (50%), cobs plant-1, plant height and grain yield kg ha-1, as well as total weeds frequency m-2 15, 30 and 45 DAS, were significantly (P>0.05) influenced by various weed control methods
The analysis of variance indicated that the all traits of maize crop among the different weed control methods was statistically significant (p
