Relative Aerial Biomass Yield of Intercroped Alfalfa with Winter Forage Cereals
In the tropical regions of the world, intercropping is mostly associated with food grain production, whereas it is receiving increased attention in temperate regions as a means of efficient forage production. The aim of this work was to determine the relative yield of aerial biomass in alfalfa or lu...
