TELLA, Romeu de et al. Effects of mineral fertilizers on peanut pod production. Bragantia [online]. 1970, vol.29, n.unico, pp. 199-205. ISSN 1678-4499. http://dx.doi.org/10.1590/S0006-87051970000100019.
Three factorial experiments were designed to compare the effects of N-P-K fertilizers on peanut (Arachis hypogaea L.) pod production on a Podzolized (Lins and Marilia) soil in the State of São Paulo. Besides the untreated controls nitrogen, phophorus and potassium were tried at the levels: 30, 45 and 30 kg/ha and 60, 90 and 60 kg/ha of N, P2O5 and K2O respectively. An increase in the yield of peanut pods was associated with phosphorus in all experiments and with nitrogen in one out of three. Yield was depressed by potassium fertilizer in all experiments.
