Field experiments were conducted in 2016 and 2017 to evaluate the effects of seeding rate and herbicide programs on weed control and pinto bean yield under irrigation. The experiments were 5 by 5 factorial randomized complete block design with five replications. The weed control treatments comprised a non-treated control, hand-weeded control, EPTC + ethalfluralin PRE, EPTC + ethalfluralin PRE followed by (fb) dimethenamid-P POST at V1, and EPTC + ethalfluralin PRE fb bentazon/imazamox POST. There were five seeding rates ranging from 247000 to 494000 seeds ha-1 planted in 19-cm rows. Weed biomass was reduced by 6 kg ha-1 with every additional 1000 seeds ha-1. EPTC plus ethalfluralin fb either dimethenamid-P or bentazon plus imazamox reduced weed biomass by at least 29% compared to the nontreated control. There was a significant effect of weed control treatment on pinto bean yield (P=0.0004). However, there was no significant seeding rate (P=0.42) or seeding rate by weed control interaction effect on pinto bean yield (P=0.38). Pinto bean yield ranged from 3.08 Mg ha-1 in the nontreated control to 4.74 Mg ha-1 hand-weeded treatment. Increased seeding rate in narrow rows is a cultural practice that can improve weed control in pinto bean but may not necessarily increase yield.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
