Ten competition periods as treatments (T1-10) could be valuable for predicting increase productivity<br/>(W) T1 to T5 were allowed to infest the crop and (WF) T6 to T10 was kept weed free, weed competition<br/>periods for W and WF i.e. 3, 6, 9, 12 Weeks after emergence (WAE) and up to harvest. So, two field<br/>experiments were conducted season 2018 and 2019. Critical Periods for Weed Control (CPWC) was<br/>determined based on relative percentage yield ton/h-1 (SY %) of weed free as a check by fitting curves<br/>regression models (linear and non-linear, which recommended losing yield value 10%. with seed yield<br/>reduction t/h-1 declined from 2.3, 2.28 WF to 0.39- 0.36 W as a checked treatment for 1st, 2nd seasons,<br/>respectively about 83.33%, 85% due to relative seed yield. Gompertz as a non linear regression equation<br/>recorded 0.99* The effects of treatment classified into 3 groups where A involved 5 superior treatments (T1, T7, T8, T9 and T10). However, T4 and T5 described inferior treatments which located in group C. Low of weed density and increasing of weed index (WI %) 80% observed for 1st season of T4 but T5 was translocated with increasing both weeds number and severed for weed index. It could be summarized that it should be keeping crop weed-free during stages 2nd week and continue until 8th week after crop emergence, which is providing maximum seed yield of soybean. |
