Some Effects of Severe Soil Moisture Deficits at Specific Growth Stages in Corn¹

Physiological and morphological responses of corn genotypes to planting date and plant population

“…Loomis (1950) observed unfavorable moisture conditions just preceding tasseling resulted in an increased percentage of stalks which failed to develop an ear shoot to the silk stage, Denmead and Shaw (1960) presented data indicating moisture stress during the period from tassel emergence to silking resulted in 50 per cent yield reduction whereas earlier or later periods of stress resulted in only 20-25% yield loss. These findings are in agreement with results of Barnes (1966), Robins and. Domingo (1953), Tatum and Kehr (1951), and.…”

Morphological and physiological traits associated with barrenness and grain yield in the maize breeding population, Iowa Upright Leaf Synthetic #1

“…Lack of moisture during this period usually results in delayed silking and inadequate pollination and fertilization (Robins and Domingo, 1953;Zuber and Decker, 1956;Barnes and Wool ley, 1969). Moisture stress during the tassel-emergence and silking period resulted In a 50% yield reduction compared to only a 20-25% yield loss for earlier or later periods of stress (Shaw and Loomis, 1950;Denmead and Shaw, I96O).…”

Effect of Temperature on Flower and Pod Abscission and Yield of Three Soybean Genotypes

“…Similar results were found by Terashima (2001), Shi et al (2001), Morita. (2000, Robins and Domingo (1953). Imposing any kind of high temperature is expected to increase the process of abscission and thereby reduce the yield of soybean.…”
