The Effects of Arbuscular Mycorrhizal Fungal Inoculation and Mulch of Contrasting Chemical Composition on the Yield of Cassava under Humid Tropical Conditions

The influence of arbuscular mycorrhizal fungus (AMF), Glomus deserticola, and leaf mulch from Gliricidia sepium and Senna siamea on the yield of cassava (Manihot esculenta) in a degraded alfisol of southwestern Nigeria was investigated. Inoculation in conjunction with mulching increased cassava tuber yield by 40–278% over the control. The highest yield was obtained with G. sepium and S. siamea mulch applied together in equal proportions. The results are explained in the light of the growth-enhancing effects of AMF, encouraged by the ameliorating effects of mulch on the soil structure and nutrient contents

EFFECTS OF ALLEY CROPPING AND ARBUSCULAR MYCORRHIZAL INOCULATION ON THE GROWTH AND YIELD OF MAIZE (Zea mays L.) cv TZ SWAL-1

A field experiment was conducted in a Rhodic Kandiustalf (Balogun series) soil in southwestern Nigeria to investigate the effects of Glomus deserticola on alley cropped maize. Inoculated maize performed best in Gliricidia sepium alleys with dry grain yield of 1108.4kgha-1 compared to 961.4, 661.2 and 472.1kgha-1 from G. sepium interplanted with Senna siamea ,Senna siamea alone and control subplots respectively. For the uninoculated, the lowest yield was obtained from S. siamea while the highest yield was obtained in Gliricida interplanted with Senna subplots.

Effects Of Arbuscular Mycorrhizal Fungus And Pruning Regimes Of Woody Legumes On The Tuber Yield Of Alley-Cropped Cassava

The effects of arbuscular mycorrhizal fungus (AMF), Glomus deserticola, Trappe, Bloss and Menge (INVAM, CA113), on the tuber yield of cassava (Manihot esculenta Crantz) as influenced by two hedgerow tree species and their mixture pruned at two-and three monthly intervals were investigated in an alley cropping experiment. In alley-cropped plots, inoculation with G. deserticola increased cassava root tuber yield by 205% over non-inoculated plants at two-monthly pruning regime and 19-81.8% higher tuber yield than three-monthly pruning regime. Mixing the two tree species, Gliricidia sepium and Senna siamea in the same hedgerow, particularly with AMF inoculation, significantly improved cassava tuber yield compared to either of the tree species planted alone.
