Other claims from this paper (13)

Observation Most measured traits had no significant interaction between row spacings.
Observation Days to 50% flowering was the exception to the nonsignificant interaction result.
Intervention effect Main effects of inter- and intra-row spacing differed significantly for days to maturity.
Intervention effect Main effects of inter- and intra-row spacing differed significantly for plant height.
Intervention effect Main effects of inter- and intra-row spacing differed significantly for number of fruits per plant.
Intervention effect Main effects of inter- and intra-row spacing differed significantly for fruit weight.
Intervention effect Main effects of inter- and intra-row spacing differed significantly for marketable fruit yield.
Intervention effect 40 cm intra-row spacing gave 74 fruits per plant, statistically at par with 30 cm spacing and 68 fruits.
Intervention effect 30 cm intra-row spacing produced the largest fruit size, 71.1 g.
Intervention effect 20 cm intra-row spacing produced smaller fruit, 67.5 g.
Intervention effect Fruit size did not differ significantly among inter-row spacings.
Intervention effect 20cm intra-row spacing gave the highest marketable yield, 651.4 qt ha-1, statistically at par with 30 cm spacing.
Recommendation The authors recommend 60 cm inter-row and 30 cm intra-row spacing for yield and fruit size in Merebleke.
