- Lucerne sowing is characterized by a rectangular spatial arrangement, i.e. greater distance between sowing rows than between plants in the row. Therefore, the reduction of row spacing generates more square spatial arrangements that can influence intraspecific competition and resource utilization, especially radiation, and thus biomass. The experiment included different row spacings (10-15-17.5-20 and 30cm) at the same plant density in a pure lucerne crop during the first production year. Total aerial dry matter (ADM) was increased by narrow spacing (more square arrangements) up to an optimal distance (around 13cm) (R2=0.60). ADM ranged from 2292 to 1670gDMm-2 for 15 and 30cm row spacing, respectively. Plant density was the forage yield component most affected by row spacing and it increased with narrow spacing (0.15≥R2≤0.5). ADM responses to reduced row spacing were positive as revealed by both a linear increase in radiation interception (PARia) (R2=0.76) and an optimal pattern in radiation use efficiency (RUE) (R2=0.45). PARia in the first year showed an increase of 8MJcm-1 of spacing reduction. RUE values ranged from 2.0 to 1.6gDMMJ-1 for 15 and 30cm row spacing, respectively. The leaf area index (LAI) was also affected by row spacing. Additionally, seasonal variation was found for the main variables but did not interact with row spacing. In conclusion, reducing row spacing to an optimal distance is a practice that allows for more favourable spatial arrangements of a lucerne crop and has a positive impact on forage production. © 2012 Elsevier B.V..
