| Abstract | ||
| Field experiments were carried out at Giza Experimental Research Station, in 2010/2011 and 2011/2012 seasons, to investigate the effect of preceding crop and wheat tillage system under some weed control methods on wheat yield and its components. Strip plot design with three replications was used The main plots were allocated to three preceding crops (sesame, maize and cowpea), while sub -plots were occupied with the following tillage systems, tillage and no-tillage weed control methods included, hand weeding twice at 30 and 45 days after sowing (DAS) and application of herbicides (sinal + puma super) were devoted to the sub–sub plots, on growth, yield and yield components and protein yield of wheat cultivar Sids 12. Data revealed that the highest values of yield and yield attributes was obtained when wheat was sown after cowpea followed by maize, whereas the lowest productivity indicators were recorded when sown after sesame. The results indicated that all characters were significantly affected by preceding crop in both seasons, except spike length, number of spikelts/spike and weight of 1000 grains in the first season and number of spikelts/spike in the second season. The effect of two tillage systems on growth, yield and its components of wheat were observed in both seasons and revealed that the tillage systems had significant effects on most characters studied of wheat in both seasons. Results showed generally that, the chemical weed control for broad leaved or grassy weeds was more efficient than hand weeding control. The lowest values of dry weeds were recorded from sinal combined with puma super followed by hand weeding treatment, while the highest values for these character were obtained with unwedded methods. The interaction between preceding crops, tillage systems and weed control methods significantly affected number of spikes/m2 ,weight of grains/spike ,grain yield/fed and dry weight of weeds g/m2 in both seasons. | ||
