Abstract
Riau Province has about 49% of dry land, which has a large partly undulating topography, for it to
overcome the low yield of corn in this area conducted assessment cropping systems and mulching on maize
cultivation. The purpose of this study is to find ways of planting and mulching the right dose in the cultivation of maize
on sloping land in Riau Province that carried out in Kepenuhan, Rokan Hulu, on MT 2011. Regional studies have Ultisol
soils with agro climatic zones B1. The study was arranged in a randomized block design with two factor. Factor I is
cropping systems consisting of: (1) parallel to the slope cropping system, with distances in rows 20 cm, one plant
per hill and the distance between rows of 75 cm, (2) planting system parallel to the slope, with distance role in rows
40 cm, two plant per hill and row spacing of 75 cm, (3) System tiles, 20 cm x 75 cm, one plant/hole and (4) Spacing
40 cm x 75 cm, two plants/hill. Factor II is a dosage of rice straw mulch, which consists of (a) 2 t/ha, (b) 4 t/ha ,and
(c) 6 t/ha. The result showed the system of planting 1 (parallel to slope planting system, with the distance in rows
20 cm, one plant per hill and the distance between rows 75 cm) with rice straw mulching as much as 6 t/ha, giving
the best growth and yield compared to other treatments.
