บทคัดย่อ (EN): A field experiment was carried out at the Rubber Research institute of Nigeria (RRIN) during the 2001 and 2002 cropping seasons to evaluate the viability of intercropping cocoyam with matured rubber plantation and to quantify the effects of Rock phosphate application and indigenous mychorrhizal fungi on the yield of cocoyam and rubber latex. The results indicated that intercropping with matured rubber reduces the edible cormel yield of cocoyam by 27, 23, and 65% in the O, 60 and 120 kg P ha-1 treatments respectively. It also delayed the leaf shedding of cocoyam by about 9 weeks. However, the latex yield of rubber was not significantly affected by cocoyam intercropping. Land Equivalent Ratio (LER) values of 1.31, 1.60 and 1.68 were obtained from 0.60 and 120 kg P ha-1 treatments respectively in the rubber/cocoyam intercrops indicating higher land use efficiency in intercropping cocoyam with matured rubber than planting cocoyam or rubber as sole crop. Vesicular Arbuscular Mychorrhizal (VAM) spore counts and root colonization were found to be higher in treatments receiving less P fertilization. It was suspected that the VAM activities could have accounted for bringing the cocoyam yield of treatments with no P application at par with those receiving P fertilizers in addition to other factors affecting the availability and utilization of P in acid soils. The higher land use efficiency and the possibility of securing subsistence through arable cropping while simultaneously gaining cash income through rubber latex would make cocoyam intercropping with matured rubber attractive to smallholder farmers and ultimately increase the rubber plantation establishment in Nigeria.
