植物を標準的な格子状に配置します。
正常に発芽すると予想される種子の割合です。
種子1粒あたりの重量で、必要な種子の総重量を見積もるために使用します。
植栽密度 = （面積 ÷（条間 × 株間））、パターンと発芽率で調整
株/m² = 1 / (畝間隔 × 株間)
1ヘクタール = 10,000 m² ・ 1エーカー = 4,046.86 m²
Rectangular planting places plants in a grid pattern with equal spacing. Triangular (offset) planting staggers every other row by half the plant spacing, fitting approximately 15% more plants in the same area while maintaining similar spacing between individual plants.
Optimal plant spacing depends on crop type, variety, soil fertility, and climate. Corn typically uses 30-inch rows with 6-8 inch plant spacing. Consult seed company recommendations and local extension services for variety-specific guidance.
Germination rate is the percentage of seeds that successfully sprout and establish plants. A 90% germination rate means you need to plant about 11% more seeds than your target population. Most commercial seed has 85-95% germination depending on the crop.
Modern corn hybrids perform best at 30,000-36,000 plants per acre (74,000-89,000 per hectare) in the US Corn Belt. Optimal density varies by hybrid, soil type, and growing conditions. Higher populations work best in high-yield environments with adequate moisture.
