Interference of Urochloa plantaginea on Morphophysiology and Yield Components of Black Beans
Journal of Agricultural Science, 2019 Among the factors which affect crop productivity, there are weeds which compete for environment resources. The objective of this work was to determine the periods of interference of alexandergrass on the morphophysiology and productivity components of black beans. The experiment was conducted in a complete randomized block design with four replications.
