A field research was carried out during summer 2015 at the College Farm, Navsari Agricultural University, Navsari to evaluate “Integrated weed management study in summer maize (Zea mays L.). Ten treatments comprising of weed management practices including cultural, mechanical and chemical treatments were evaluated in randomized block design with three replications. Weed free treatment (T2) was preformed mostly superior than all the other treatmentsfor growth, yield and yield attributes. Significantly higher grain yield and straw yield (kg/ha) were registered under weed free treatment, which is being statistically at par with pre-emergence application of atrazine @ 0.75 kg/ha + pendimethalin @ 0.75 kg/ha (T8), pre-emergence application of alachlor @ 1.5 kg/ha + atrazine @ 0.5 kg/ha (T7), preemergence application of atrazine @ 0.75 kg/ha +2, 4-D @0.5 kg/ha (T9), pre-emergence application of atrazine @ 0.75 kg/ha (T6) and post-emergence application of atrazine @ 1.5 kg/ha at 30 DAS (T10) which was further at par with T4 and T5 for straw yield. At harvest, the significantly lower monocot and sedges were noted under weed control through sugarcane trash mulch @ 5 t/ha (T4). The significantly minimum dry weight of weeds at harvest and highest WCE were recorded under treatment of pre-emergence application of atrazine @ 0.75 kg/ha + pendimethalin @ 0.75 kg/ha. Significantly lowest values for growth, yield and yield attributes as weed control efficiency registered under weedy check (T1). Not Available |
