The aim of this work was to evaluate the performance of fourteen genotypes of banana tree, in the North Region of the state of Paraná, Brazil. The experiment was installed and carried out, without irrigation, in a commercial field located in Andirá, PR, Brazil, from 2007 to 2009. A completely randomized design with eight replications and one plant per parcel was used. The genotype FHIA 17 was outstanding of the rest presenting the best set of agronomic characters. The genotypes PA42-44, PV94-01 and 'BRS Princesa' presented similar characteristics to the comercial varieties 'Prata Anã', 'Pacovan' and 'Maçã', respectively, being alternatives of grow by its resistance to the black and yellow sigatokas and Fusarium wilt.

Due to the lack of knowledge on the nutritional status of the coffee shrub, DRIS method was introduced in coffee culture in the northern region of the state of Parana, Brazil. Current research aimed at establishing a data base for DRIS guidelines in coffee culture and introducing other parameters for the rational and balanced application of fertilizers. Assay was performed between February 2011 and February 2012 (Harvest 2011/201) in coffee plantations in the municipality of Pitangueiras PR Brazil, 23o 14’ 03” S and 51o 35’ 06” W; altitude 600 m. Leaf samples from 75 coffee shrub lots were retrieved from 69 plantations, featuring cultivars IAPAR 59, IPR 98, IPR 99, Catuaí, Mundo Novo and Tupi. DRIS norms were established for the nutritional diagnosis of the coffee shrub for the northern region of the state of Paraná through the criterion of productivity at 55 sacks ha-1. Data revealed that potassium constituted the highest deficiency, followed by Cu and Zn. Fe, S and Mn had excessive rates with regard to parameters at regional level. © 2015, Editora UFLA.
