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.
