Technical Abstract: Okra shows yield response to the altered far-red to red (FR/R) ratios in light reflected from colored mulches to these plants. Our objective was to determine whether okra plants also respond to altered FR/R ratios when placed in directionally oriented rows, or at various plant spacings. This is highly relevant to growers with limited resources. Okra yield was evaluated at two row orientations and three row spacings (45, 90, and 180 cm). Plants grown in north/south oriented rows received reflected light with higher FR/R ratios and had greater yields than plants grown in east/west rows. Within a direction, plants grown in rows which were 180 cm apart had greater yield.
