Effect of soil tillage and mycorrhiza application on growth and yields of upland rice in drought condition
Journal Title: Asian Journal of Agriculture and Biology - Year 2018, Vol 6, Issue 2
Abstract
Dry land management technology for food crop agriculture with soil conservation, organic matter management, and water management. This study aims to determine the effect of soil treatment and mycorrhiza on growth and yield of upland rice in drought stress conditions. This experiment uses the Split Split Plot design consists of 3 factors: The first factor as the main plot of mycorrhizas consisting of no mycorrhizal and mycorrhizal administration. The second factor as a plot is the soil cultivation consisting of no soil preparation) and treatment. The third factor as Multiplication Children is Varieties consisting of three groups of varieties namely Toleran group (Ciapus Varieties, Inpago Varieties 4 and Varieties inpago 8) moderate varieties group include (Inpago Varieties 5, Varietas situ bagendit, Inpago Varieties 7 and Varietas towuti) and the susceptible varieties are (In jari 6 varieties, Inpari 33 varieties and synthetic varieties). Treatment without tillage and without mycorrhiza decreased leaf area, root canopy ratio, leaf proline content, degree of root infection and dry grain production. Soil sampling and mycorrhizal fertilization of Inpago 4 tolerant varieties showed a mechanism of avoidance against drought stress by increasing leaf area, root canopy ratio, leaf proline content and root infection. The highest dry grain production was found in the tolerant (Inpago 4) varieties group of 7.5 tons per ha and can be planted in drought stress conditions at rainfall ± 3.2 mm / day.
