Double Row Planting Arrangement

In order to find essential information for efficient management of corn and sorghum fields many separate experiments have been done to getting high yield. An increasing number of plants per area, without negative effect to vegetative and productive yield components, double row planting arrangement suggested. Researches with plant densities of 45000-350000 plants per hectare and planting patterns of a single row, double row with 15 cm space, and double row with 20 cm space arranged in factorial experiments have been done.

Results showed that with double row planting arrangement, corn plant density could be increase to 95000, 85000, and 75000 plants per hectare for silage, grain, and sweet corn respectively and forage sorghum up to 300000 plants per hectare without any negative effects on ear size and other yield components. Finally, with double row planting arrangement competition between plants decreased and plant density could be 15-25 percent increased and lead to harvesting maximum yield (20%).
