Abstract
Eight field experiments were carried out between 1977 and 1979 to determine the nutrient requirements of peanuts (Arachis hypogaea) when grown in a sandy soil next to the Ord River Valley. Treatments tested were phosphorus, potassium, sulfur, calcium, nitrogen and inoculation with Rhizobium. Phosphorus applied to the virgin soil at 20 kg/ha P increased pod yields by 36% (from 3.35 to 4.56 t/ha) and kernel yields by 40% (from 2.24 to 3.14 t/ha). Phosphorus had no effect in an experiment, which followed a fertilized crop of sorghum. Calcium as either limestone or gypsum increased kernel yields of 'Virginia Bunch' peanuts by up to 16% and 46% in two seasons, respectively, through improvements in kernel weight and shelling percentage. Potassium, nitrogen and inoculation did not affect any economic attribute.
