Planting Season

The effects of cultivar and planting season on growth development and pod yield of snap bean (Phaseolus vulgaris L.) were analysed in a 2-year, 2-location experiment in Spain. Phenology, pod production, and quality differed significantly among snap bean cultivars. Planting season had a significant effect on most pod traits except the number of seeds per pod, length, thickness, soluble solids content, tenderness, and string, and this effect varied markedly among environments. High and negative correlations for vegetative growth traits between early and late planting seasons confirmed the strong planting season influence on those traits. Fresh pod yields were highest in the early planting season, and the longer pod maturation phase could be considered to be one of the main factors. Planting of snap bean earlier in the season should thus contribute to a longer growing vegetative cycle and greater productivity than normal or summer and late autumn planting. The earliest maturing snap bean cultivars would have the highest fresh pod yields in late planting seasons, while the latest maturing snap bean cultivars would have the highest yields in early and normal planting seasons. These results will allow breeders to optimise the level of earliness for each planting season without reducing the yield. This is a key requirement for snap bean crops, and it is the first step towards selecting parental lines with stability of pod traits to be used in breeding programs for different growing areas and planting seasons.

Because of interest in maximizing production per unit area in regions where the land base is limited, the effects of planting density; (16–116 plants m−2) and planting design on pod yield of bush snap bean (Phaseolus vulgaris L.) were measured in replicated field trials with cv. Harvester in 1980 and 1981. Three planting designs were used: (a) conventional row designs with interplant spacing of 5 cm and interrow spacing of 20, 45, 80 and 125 cm; (b) square designs with interplant and interrow spacings both at 10, 15, 20 and 25 cm; and (c) triangle designs (honeycomb) with plants arranged at equal distances of 10, 15, 20 and 25 cm from each of their six nearest neighbors. In all three planting designs, higher planting densities (up to 116 plants m−2) gave higher pod yields per unit area. Except for the lower response in the square design in 1981, increases in yield with increasing density were similar for all designs in both years. Pod yields did not differ from one design to the other in 1980. In 1981, the triangle design gave the highest average yield and the row design gave the lowest average yield. The results confirm observations of yield advantages in planting designs which use equal spacing in all directions.Key words: Yield-density relationship, row spacing, honeycomb design, snap bean, Phaseolus vulgaris
