Growth and Yield Respones of Maize (Zea mays L.) to Soil Water Deficits. Ⅱ. Effects of Water Deficit Timing and Strength

Abstract

Water is a major limiting factor on maize production in Taiwan. It is very important, therefore, to study the relations of soil moisture stress and maize (Zea mays L.) yield under local conditions. This field work was conducted on the experimental farm of Taiwan Agricultural Research Insitiute (TARI) at Wufeng, Taiwan to evaluate the relative effects of water deficit timing and strength on the growth and yield of maize, cultivar Tainung No. 1.水分為本省玉米生產之一項主要限制因子，因此殊有必要詳加探討各局地環境下玉米生長與產量和土壤水分之關係。本文研究係以玉米單交品種臺農一號為材料，在臺灣省農業試驗所農場進行田間試驗，評估玉米缺水時期及土壤缺水程度對玉米生產之影響。
