Abstract
Amaranth, Amaranthus spp., is a promising summer leafy vegetable for the Southern United States. Planting of greens is usually spread over a period of time to enable growers to supply the market on a continuous basis. This study was carried out to establish the time span for planting amaranth in Middle Georgia. A. tricolor, genotype “RRC 241” was planted in a randomized complete block experiment on six planting dates one month apart between 14 April and 14 September. Data on plant height, photosynthetic rate and green fresh weight were collected 40 days after planting. June, July and August plantings had similar plant height, which was significantly greater than other planting dates. The plants from June seeding had the highest photosynthetic rate of 25.2 μmol m-2 s-1. Green yields from April, May, June, July, August and September plantings were 0, 0.1, 9.1, 7.4, 5.7 and 2.5 Mg ha-1, respectively. It was inferred that June and July were the best months for planting amaranth in Middle Georgia.
