This book was released on 1976 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Short term drought periods during the rainy season, low soil water storage capacity, and highly acidic soils 80% Al sat. which inhibit root growth all give a combined effect of limiting yields for most crops in the Central Cerrado of Brazil. With those problems in mind, experiments were conducted in Brazil for two years to study the effect of a veranico (drought) on corn (Zea mays L.) growth and yield. The experiment were designed to provide a drought avoidance for the corn plant. In one experiment, soil management techniques were used to allow a crop to tap a greater quantity of the soil water stored in the soil. A second experiment used crop management techniques to increase water use efficiency by decreasing water loss from the soil surface and from the cornleaf. The soil management experiment consistent basically of lime rates and depths of line incorporation, i.e. 0-lime, 8T/ha lime incorporated to a 15 cm depth and 8T/ha lime incorporated to a 30 cm depth, and a broadcast verses banding application of phosphorus. Without plant water stress, no depth of lime effect was noted on plant growth before the tasseling stage. From silking to grain maturity, the deep limed plants maintained a longer period of active plant growth by delaying leaf senescence. The unlimed corn plants were always inferior to the limed plants with the dry-cool season crop showing a more pronunced decrease in plant growth. Measurements taken during an actual veranico or a simulated veranico showed that deep liming had a large effect (...).

This book was released on 1989 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assumptions relating to the effect of water stress on crop growth inherent in the crop simulation model (Stockle & Campbell, 1985) used here, appear to be valid when applied to Cerrado conditions. Temperature and light effects on photosynthesis are considered in the calculation of a non-stressed photosynthetic rate, which is dependent on the amount of photosynthetically active radiation intercepted by the canopy. Thus, model predictions are sensitive to the predicted partitioning of potential evapotranspiration. Predicted leaf area indices and dry a matter accumulation over time compared well with measured data. Dry matter and leaf area were overpredicted in the most extreme water stress treatment, possibly due to soil fertility/water interactions not represented in the model. Harvest index was related more to water stress accumulated throughout the growing season, than to water stress accumulated during pollination, as was suggested by Stockle & Campbell (1985). Hourly predicted leaf water potential changes and corresponding changes in transpiration and photosynthetic rate represented the dynamics of water stress realistically and were consistent with expectations.
