Abstract :The effects of varying potassium and calcium rates on the peanut yield was studied using three Hawaiian Latosols in a pot experiment. Total vegetative yields(whole plant),shelled peanuts and shelling percentages as related to soil treatment were analyzed statistically. Total vegetative yield increased significantly with potassium treatment in the Paaloa soil. On the Wahiawa soil response to soil treatment as measured by any form of peanut yield failed to give significant results. A significant interaction was found in total vegetative yield as a resut of soil treatment in the Waimanalo soil. When no potassium was added to the soil, increasing calcium levels eriously depressed the Shelled peanut yield and shelling percentage. A significant correlation was established between shelled peanut and total vegetative yield for all soils. The scatter diagram (Fig.13) indicates that the limiting factor or factors, for the peanut yields may have been a variable or variables, other than those for which the experiment was designed. It was presumed that the ratio of K/√<(Ca+Mg)/2> of the plant was a sensitive indicator of the shelled peanut yield. The potassium and calcium treatments significantly affected the potassium, calcium, and magnesium uptake of the peanut plant as shown by tissue analyses. An antagonistic trend between potassium and calcium uptake was evident on the Paaloa and Wahiawa soils. On the Waimanalo soil, the calcium treatment significantly affected the potassium uptake.
