| Abstract:
The effect of three spacings on plant growth, yield and cycle duration of ‘Nanicão’ Cavendish banana was studied in an alluvium soil, in Guaramirim, North Coast of Santa Catarina State, Brazil. Spacings of 2.0 x 3.0, 2.0 x 2.5 and 2.0 x 2.0 meters were tested, with one follower per cycle. The increase in plant density, practically, did not affected the final development in the two first cycles, but reduced both the pseudostem perimeter from the second ratoon cycle and plant height from the fourth ratoon cycle on. The strong density effect on the yield per cycle, verified in the plant crop and first ratoon cycles, became unimportant from the second ratoon cycle on, due to less bunch weight in higher densities in these cycles. The increase in the density led to a longer crop cycle, mainly from the first ratoon cycle on. In this way, the total yield over a 98-month period tends to the balance among the treatments. | |
