Study of the Effect of Trifloralin Herbicide, Seed Rate and Planting Distances in Controlling Broad-Leaf Weeds Associated with Wheat (Triticum aestivum L.) Under the Conservation Agriculture System

Abstract

The study was conducted in the fields of one of the farmers in order to control the broad Weeds associated with the wheat crop by chemical and agricultural methods and with a conservative cultivation system for the seasons 2018/2019 and 2019/2020, and the study included three factors: the first factor is the Trifloraline herbicide and at two levels (0, 1248) cm3 / ha, the second factor rates the effectiveness of the herbicide, and the third factor rates the effectiveness of the cultivation system. Important findings are summarized below. The study was conducted using the system of global experiments in the split-split plots, with seeding at three levels (80, 100, and 120) kg / ha, and the third factor, planting distances at two levels (15 and 30) cm between the lines, with design of complete random sectors and with three replications; Herbicide treatment reduced all traits significantly compared to comparison treatment. Seeding rate increased broad-leaf weeds and side branches and decreased bush susceptible leaf dry weight. All traits improved at 30 cm between planting lines. Interaction achieved. In the second season, the herbicide treatment and 120 kg/ha seed rate reduced broadleaf weed dry weight. The herbicide treatment and 15-cm distance reduced all traits and seasons. In the second season, the interaction between the seed rate of 120 kg/ha and the distance of 15 cm between the planting lines reduced the dry weight of the broad-leaf weed, while the herbicide treatment and the seed rate of 80 kg/ha did the same. In the second season, broad-leaved weeds decreased in dry weight by 15 cm.
