Abstract

Florunner peanuts (Arachis hypogaea L.) were subjected to 35 and 70-day drought periods during several growth stages (days after planting). Drought conditions were maintained by the use of automatic rainout shelters covering groups of drainage lysimeter plots.

Detrimental effects of 35-day drought periods were greatest from 71–105 days after planting, least for 106-140, and intermediate for 36-70 days after planting. Seventy days of drought extending from 36 through 105 days after planting effectively eliminated pod production, whereas 70 days of drought during the period of 71 through 140 days after planting reduced but did not completely eliminate the production of marketable pods.
