Bio-agroeconomic returns in beet-cowpea intercropping by optimization of population densities and spatial arrangements

One of the great challenges beet and cowpea cultivation in crop association is to maintain their productivity as that sole counterparts semi-arid environment. In this context, objective work assess whether there bio-agroeconomic return associations beet-cowpea by optimization population densities spatial arrangements component crops. Experiments were performed randomised complete block designs with treatments arranged a 4 × 3 factorial scheme, four replications. The first factor was (100, 80, 60, 40% recommended single - RPSC) beet, second (2:2, 3:3, 4:4), formed (B) rows alternating (C) rows. competition agronomic indices evaluated aggressiveness, competitive ratio, land equivalent actual yield loss, intercropping advantage productive efficiency index. economic indicators gross income, net rate profit margin. High agro-economic can be obtained when well-managing factors production, arrangement greatest 40 100% RPSC for respectively. 2:2 between crops one best performance higher return. dominant while dominated.
