Abstract

The ability of a maize plant canopy to intercept sunlight during grain filling determines its yield. This research explored options to increase the ability of maize plants to intercept sunlight, especially at the end of vegetative growth. A field trial to study the effect of row planting orientations (north-south and east-west) and row patterns (single row and double row) was conducted under rainfed conditions in Lombok, Indonesia. In the single row treatment, the spacing was 70 cm between rows and 20 cm in the row (70 x 20 cm). A spacing of 35 x 20 cm was used for the double row treatment with 70 cm apart of the two double rows. Treatments were arranged in a Split-plot design with planting orientations as main plots and planting models as sub plots. Each treatment was replicated three times, and the size of each plot was 3.5 x 3.5 m. Results of the experiment showed that the canopy of the plants with north-south row orientation intercepted much more sunlight than that of the east-west orientation. At the end of the vegetative stage, the canopy of the plants planted in double rows intercepted 15% more sunlight than that in the single row. Maize grain yield in the double row was 25% higher than that grown in a single row
