Type: article
Abstract: The aim of this study was to evaluate the agronomic performance and fruit quality of 'Maçã' banana cultivar.A field experiment was conducted to study the effect of phosphorus (P) on the cultivar.The study area presents a subtropical climate, where the mean temperature is 22°C; and the mean rainfall is 1377 mm.The experiment was conducted from November 2012 to May 2014.The experiment design was totally randomized, consisting of six treatments (0, 40, 60, 80, 100 and 120 kg P 2 O 5 ha -1 ) and seven repetitions.The results indicated that plant height, pseudo-stem diameter, number of live leaves, yield and fruit numbers per bunch increased at 51, 45, 44, 34 and 40 kg P 2 O 5 ha -1 , respectively.The shortest harvest cycle was of 480 days at 60 kg P 2 O 5 ha -1 .In unripe bananas, RSC improved 13% at 47 kg P 2 O 5 ha -1 ; while the highest level of P, Ca and Mg were obtained at 74, 41 and 58 kg P 2 O 5 ha -1 , respectively.During banana ripening, maximum fruit firmness (3.07 N) was achieved at 63 kg P 2 O 5 ha -1 .Application of triple superphosphate fertilizer (at 34 kg P 2 O 5 ha -1 ) increased yield, without changing physicochemical characteristics.
