Abstract: To examine the effect of pre emergence herbicides, plant extracts and mulches on yield and yield components of maize, a field experiment was carried out at New Developmental Farm, The University of Agriculture Peshawar-Pakistan during summer crop season 2016. Maize variety “Azam” was sown in Randomized Complete Block (RCB) design having four replications and ten treatments i.e. hand weeding, Dual Gold 960 EC (S-metolachlor 1 L ha-1), Stomp 330 EC (pendimethaline 2.5 L ha-1), atrazine 1.25 L ha-1, Eucalyptus ca… Show more

“…When herbicides are sprayed, they interact with weeds and disrupt various biochemical processes such as inhibition of photosynthesis, chlorophyll bleaching and as a result weeds are killed (Yang et al, 2010;El-Hadary and Chung, 2013). In line with results of the current research where Primextra herbicide reduced weed density, relative weed density and fresh and dry biomass of maize weeds, Ugwunna et al, (2015) and Khan et al, (2013) found that Primextra gold significantly reduced weeds of cucumber, maize and wheat and hence improved their yield. T1 = Control, T2 = Wheat straw mulch, T3 = Dry leaves of eucalyptus, T4 = Rice straw mulch, T5 = Grass clippings, T6 = Living mulch (soybean crop), T7 = Black plastic mulch, T8 = Herbicide (primextra at 400 mL acre -1 ), BCR = Benefit cost ratio, USD = United states dollar.…”

“…It was seen that pesticides were efficient in weed control in general. It was observed that this result was in line with the study results obtained by Khan, Khan, Khan, Imran, Idrees & Bıbı (2013), Shehzad, Maqsood, Anwar-ul-Haq & Niaz (2012) and Ghulam, Ali, Raffaqat, Zafar, Muhammad & Muhammad (2010). Although timing of 2015-2016 (15869) season pesticide treatment was better than the timing of 2014-2015 (4812) season, the number of weeds was higher.…”

“…Average grain yield per spica in 2015-2016 (1.09 g) was higher than the grain yield per spica in 2014-2015 (0.96 g) (Table 8). Pesticide treatment's positive effect on grain yield per spica was in line with the results obtained by Blandino, Minelli & Reyneri (2006), Shehzad, Maqsood, Anwar-ul-Haq & Niaz (2012), Khan, Khan, Khan, Imran, Idrees & Bıbı (2013), Rodrigo, Cuello-Hormigo, Gomes, Santamaria, Costa & Poblaciones (2015). On the other hand, it was observed that grain yield per spica was higher in all of the WV treatments except for 0.5% and 2% ml WV treatments when compared to the control.…”
