RESENDE, Geraldo M. de  e  COSTA, Nivaldo D.. Yield characteristics of watermelon in different planting spaces. Hortic. Bras. [online]. 2003, vol.21, n.4, pp.695-698. ISSN 0102-0536.  http://dx.doi.org/10.1590/S0102-05362003000400025.

The yield of watermelon as a result of different planting space was evaluated, from October to December 1998 in Petrolina, Pernambuco State, Brazil. The experimental design was a randomized blocks in a 5 x 3 factorial scheme, with three replications. The cultivar Crimson Sweet was planted in 2.5 and 3.0 m row spacing and in 0.4, 0.6 and 0.8 m inside the row. The 3.0 m row spacing resulted in the highest marketable yield with 42.46 t ha-1. Higher yields (42.50 and 45.29 t ha-1) were obtained with the 0.2 and 0.4 m plant spacing, with no difference between them. No significant differences were observed for unmarketable fruit yield in the row spacings. However, the smallest plant spacing (0.4 m) showed the highest yield with 20,21 t ha-1, followed by the 0.6 m (12.86 t ha-1) and 0,80 m (8.62 t ha-1). The increase of the row and plant spacing produced larger sized fruits, and the spacing 3.0 x 0.8 m showed the highest weight of fresh fruit mass (8.83 kg). The largest number of fruits per plant (1.35 fruits) was observed in the 3.00 x 0.8 m spacing.
