Effect of Weed Control Treatments and Row Spacing on the Yield and its Components of Faba Bean and Companion Weeds

Abstract

To determine the impact of four weed control treatments (the weed-free treatment, the weedy treatment, Bentazon spray at the recommended rate of 2 liters ha−1, and the same herbicide at half the recommended rate of 1 Liter ha−1, as well as the weedy treatment and the weedy row spacing of 40, 50, and 60 cm) and three row spacing (40, 50, and 60 cm) on the development and harvest of br, a field experiment was conducted during the winter of 2020. The experiment used a Split Plot Design layout with three replicates and was conducted using a randomized complete block design (RCBD). Row spacing in the sub-plots and weed control treatments in the main plots. As shown in the data, weed control treatments significantly reduced the dry weight of weeds compared to the weedy treatment. The dry weight of the weeds was reduced by 86.71% when Pentazone was sprayed at a rate of 2 liters ha−1, and this effect was visible in both the yield and its components. Maximum seed yield was achieved at 6.05 t ha−1 when rows were spaced 40 cm apart, 7.91 t ha−1 when they were spaced 50 cm apart, and 7.79 t ha−1 when herbicide was sprayed at a rate of 2 liters ha−1 at a distance of 40 cm apart; these three treatments did not differ significantly from each other, but did differ significantly from all other treatments. The lowest seed output was seen in the weedy condition at all three distances.
