Abstract
Abstract Experiments were conducted in the field and greenhouse to evaluate interactions between application of B, Ca (gypsum) and K upon yield and quality of ‘Comet’ variety Spanish peanuts ( Arachis hypogaea ). In the greenhouse, using Eufaula fine sand, peanuts received factorial treatment combinations of three rates of B (0, 0.25, and 0.50 ppm), three rates of Ca (0, 88, and 176 ppm as gypsum), and three rates of K (25, 50, and 100 ppm). Factorial treatment combinations of three rates of B (0, 0.56, and 1.12 kg/ha), and three rates of Ca (0, 65, and 130 kg as gypsum/ha) were applied under field conditions at three locations. Under greenhouse conditions, significant interactions between the effects of B and Ca on growth and quality were observed. High Ca levels in the absence of applied B resulted in increased yields, lower seed quality (percent sound mature kernels), and extremely large increases in amounts of internal damage (due to B deficiency). No significant difference in yield response to B and Ca applications were found under field conditions. Peanuts showed a significant B by K interaction. Application of B with rates of potassium resulted in small increases in yield, except at the highest B and K levels where yields were reduced.
