Management of AMF inoculated precedent crops to mycorrhize efficiently sweet potato Ipomoea batatas (L.) Lam in succession
Main Article Content
Abstract
The use of inoculated precedent crops as via to mycorrhize efficiently crops in succession have a practice high value and overall in crops like sweet potato which its direct inoculation needs a high amount of inoculants, but in the carried out studies only 30 days between both crops have been evaluated. With the purpose of precise the effectiveness in superior intervals and its dependence of the precedent crop and sowing season 12 experiments were executed in Brown soil, using maize and two species of bean as precedent seeded in rainy and little rainy seasons and in all cases under irrigation. The precedents presented a high response to inoculation with Rhizophagus irregulare/INCAM11 in both seasons with high percentages of mycorrhizal colonization and spores in maize and rainy season. The duration of the permanence effect in the sweet potato yield depended of the precedent and it was similar in both seasons, with leguminous it was extended until 45 days, although the maize at to the 45 days was achieved between 76 to 81 % of effect and at to the 60 days disappear for both precedents. The highest yields of sweet potato were achieved with the planting in the rainy season and in the bean-sweet potato succession. The potentiality of the precedent crops inoculated to provoke the permanence effect cannot be defined through the simple comparison of the indicators of mycorrhizal functioning that are presented in them.
