Responses of maize (Zea mays L.), cowpea (Vigna unguiculata (L.) Walp) and maize/cowpea intercrop to weed interference in a subhumid tropical environment



Responses of maize (Zea mays L.), cowpea (Vigna unguiculata (L.) Walp) and maize/cowpea intercrop to weed interference in a subhumid tropical environment



Dissertation Abstracts International, B 42(12): 4641



During 1979-80 field trials on a loamy sand Oxic Ustropept in a subhumid area of Nigeria, using 40x10superscript 3, 50x10superscript 3 and 30 or 40x10superscript 3 plants/ha of maize TZB, cowpea VI TA-5 and a maize/cowpea intercrop, resp., weed interference effects on crops depended on crop season, pattern and spp. and land preparation. Significant crop yield reductions occurred when weeds were associated for at least 6 wk in the early season and 4 wk in the late season.
