ISHIMURA, Issao et al. Influence of different levels of NPK fertilizers on the yield of pole snap beans (Phaseolus vulgaris L.). Bragantia [online]. 1985, vol.44, n.1, pp.429-436. ISSN 1678-4499.  https://doi.org/10.1590/S0006-87051985000100039.

A trial was carried out at the Experimental Station of 'Pariquera-Açu', State of São Paulo, Brazil, on an organic soil, of high acidity (pH = 4.9), to determine the influence of four levels of fertilizers (0-0-0, 118-192-186, 236-384-372 and 354-576-558 kg/ha of N-P2O5-K2O respectively) on the yield of pole snap beans, cultivar Teresópolis. The results showed that the pod yield increased with the increasing levels of fertilizers applied (linear effect). The highest yield of snap bean pods was obtained at the levels of 354-576-588kg/ha of N-P2O5-K2O, respectively. The results also showed that the average weight of pods remained constant and the number of pods increased linearly with the fertilizer levels.
