SANTOS, Valbério Paolilo dos et al. Fertigation of banana cv Prata Anã with N and K in an ultisol. Rev. Bras. Frutic. [online]. 2009, vol.31, n.2, pp.567-573. ISSN 0100-2945.

The Brazilian Northeast is the main producing area, being responsible for about 35,80% of banana's national production. In spite of the favorable conditions to its cultivation, the average national yield has been a lot below its potential, due mainly to water and nutrients supply. Among all nutrients, nitrogen (N) and potassium (K) are the ones required in larger amounts by the banana. With the objective of studying the effect of four rates of N (0, 117, 235 and 352 kg ha-1 of N), and of four rates K (0, 157, 313 and 470 kg ha-1 of K2O) applied by fertirrigation in the 2º cycle of cultivation of the cv. Prata Anã, data was collected in an factorial experiment in randomized blocks, in an Ultisol of the coastal tableland, of the northeast of Brazil. There was not response to N but a linear one was observed for K. Soil K by Mehlich-1 critical level at 0,20- 0,40 m was 0,71 mmolc kg-1.
