Yield and bunch stem/bunch ratio of 'Nanicao' bananas at different densities and arrangements

This research was carried out with the objective to evaluate the effects of different densities and plant arrangement on components of yield and bunch stem/bunch ratio of 'Nanicao' banana established in Piracicaba, SP. Four d ensities (1,333, 1,666, 2,222 and 3,333 plants ha(-1)) and two arrangements (rectangle and triangle) were studied. Independent of arrangement the incr ease of density raised fruit yield of 37.24 to 75.83 t ha(-1). However bunc h mass was reduced of 30.30 to 24.79 kg due to reduced fruit mass. The bunc h stem/bunch ratio was 8% independent of density and arrangement. At densit y of 3,333 plants ha(-1) can be exported 6.80 t ha(-1) of bunch stem of pla ntation and these component of yield can be used as raw material to manufac ture paper.
