Abstract
Objectives: The aim of this research is to improve grain yield and weed control in pinto beans through buckwheat intercropping and the application of mycorrhiza.
Materials and Methods: The experiment was conducted as a two-factor factorial base on randomized complete block design (RCBD) with three replications in 2023. The first factor included cropping systems (pure pinto beans without weed control (Weedy), pure pinto beans with weed control (weedfree), and pure buckwheat without weed control, additive intercropping of pinto beans with 30, 60 and 90% buckwheat density without weed control) and the second factor included the application and non-application of mycorrhiza biofertilizer. Morphological traits, yield components and yield of both plants, weed density and biomass, and land equivalent ratio were evaluated.
Results: The highest plant height (121cm) , leaf area index (1.98) and grain yield (3732 Kg.ha-1) of pinto bean were obtained from weedfree pure cultivation, followed by intercropping of pinto bean + 60% buckwheat density without weed control. Increasing the density of buckwheat with pinto bean reduced weed biomass (from 57 to 91%) and density (from 60 to 80%) in pinto bean flowering stage. The use of mycorrhizal fungi also increased the studied traits of pinto bean and buckwheat and reduced weed biomass and density. The land equivalent ratio in all intercropping patterns was higher than one.
Conclusion: Based on the results, it suggesies that the intercropping of 60% buckwheat density with pinto bean and inoculation with mycorrhiza can improve weed control and sustainable production of pinto bean.
