摘要
The objective of this paper was to evaluate the effect of water availability in the initial development of maize, sorghum and millet. The experiment was carried at Universidade Federal de Mato Grosso, Campus Rondonopolis the period from May to June 2010. The design was completely randomized in factorial 3x3, with three water availability (30, 60% field capacity and flooded soil), three grasses (maize, sorghum and millet) and three replications. Soil moisture was maintained by the weight of the experimental plots. The variables were: plant height, dry weight of shoots, leaf number and SPAD. Maize, sorghum and millet gets greater development in water availability of 60% of field capacity, and this condition provides the highest SPAD reading. The sorghum is tolerant to flooding and drought, unlike maize which is sensitive to these conditions and millet that is tolerant to drought only.
