Abstract
Determination of the nutrient requirements of sorghum [Sorghum bicolor (L.) Moench] grown on acid soils is, a critical step in the development of plants which are adapted to these problem soils. Sorghum genotype, environment, and soil type interact with the uptake of elements and affect plant growth and production. This study compared the yields of a sorghum grain hybrid grown on a sandy loam soil at four acid pH levels. Nutrient concentrations in sorghum leaves on these soil regimes were also investigated. Grain yields declined 96% as soil pH decreased from 5.5 to 4.4. Leaf element analysis revealed that as pH decreased from 5.5 to 4.4, there was an increase in plant Al, Fe, Mn, K, P and a decrease in Cu, Zn, Mg, Ca. Interactions among several of these elements were readily apparent. Additional data involving different sorghum genotypes and different soil types are needed to establish a consistent pattern of element uptake on acid soils in relation to yield and plant production.Keywords
