	IMPACT OF DIFFERENT MULCHES ON WEED FLORA AND YIELD OF MAIZE IJAZ AHMAD KHAN^1, Z. ULLAH¹, G. HASSAN¹, K. B. MARWAT¹, AMANULLAH JAN², S. M.A SHAH³ AND SHERAZ A. KHAN³ Abstract: Field study was conducted at Agricultural Research Institute Tarnab, Peshawar during Kharif 2007 to investigate the effectiveness of various weed control measures in maize crop. The experiment was laid out in Randomized Complete Block (RCB) design, having eight treatments and four replications. The treatments were wheat straw, saw dust, polyethylene (white), polyethylene (black), newspaper, Primextra Gold 720SC @1.0 lit ha^-1, hand weeding and weedy check were also included in the studies. Data were recorded on number of kernels cob^-1, 100-kernel weight (g), biological yield of maize (t ha^-1) and grain yield (t ha^-1). For controlling weeds, the maximum grain yield was recorded in Primextra Gold 720SC, polyethylene (black), hand weeding and polyethylene (white) with grain yield of 2.98, 2.48, 2.06 and 2.03 t ha^-1, respectively. Minimum yield (1.36 t ha^-1) was recorded in the weedy check plots. ¹Department of Weed Science, Faculty of Crop Protection Sciences, ²Department of Agronomy* ³ Department of plant Breeding and Genetics, KPK Agricultural University, Peshawar-Pakistan
