A double row planting system is a form of planting system to optimize crop productivity through the spacing between rows. Double row is a cropping pattern that alternates between two rows of plants and one empty row. The distance between the two double rows is narrower compared to the distance between the two rows in the single row system, while the empty row gives an open space of 25-50%, so that each plant in the row is considered a border plant that receives relatively more light than a single row planting (conventional).The effect of peripheral plants was greater light reception so that the process of maximum assimilation can provide more production, however the plant population is not different comparing with the square plant spacing.
Why Double Row Cropping ?
● Double row system increases yields by 12.5% than conventional planting systems
● Increases the diameter of the stem from 18.4 to 18.8 mm
● Ear length from 18.0 to 18.2 cm
● Grain weight per ear 149.7 to 154.0 g
● Grain yield from 9986 to 10398 kg/ha
How Double Row Cropping is followed?
In single row cropping system the spacing between the plants is 20-25cm and between the rows is 60-75cm.In double row cropping system two rows of plants are planted together with a spacing of 6-8 inches (13-17cm) and the spacing between the two rows remains same. Here the two rows of plants are synchronized to have a uniform triangular spacing.
Planting maize in a double row creates the perfect distribution density conditions: more light, more water and more nutrients. Because there is 30 per cent more space between the seeds and therefore 70 per cent more space available for each plant, the roots can spread out in the soil much more easily.
The application of double rows in prolific and non-prolific hybrid corn plants is expected to increase production through increased photosynthetic efficiency due to reduced competition between plants in terms of light absorption, nutrition, and water, which causes increased grain yield.
