Grain yields of several corn hybrids in response to water stresses imposed during vegetative growth stages
Bennett, J.M.
Grain yields of several corn hybrids in response to water stresses imposed during vegetative growth stages - 1983 - Printed
Tables, graphs, literature cited p. 111
During trials at Gainesville, Florida, maize cv. Pioneer Brand 3160, PioneerBrand 3320, Dekalb XL-80 and McCurdy 84 aa were rain-fed, given a water-deficit period during vegetative development or fully irrigated. 5 further cv. were usedin some of the trials. In 1980, total wilting periods were 41, 17 and 0 days, resp.; corresponding values for 1981 were 55, 15 and 0 days. Although water stresses during vegetative growth in 1980 and 1981 reduced LAI by 19%, plant ht.by 17% and grain yields by 10-15% on av., total leaf number was not significantly different in any of the treatments. Rainfed plants produced grain yields of only 45% and 33% of the
