Figure 3: Maximum fraction of incident PAR intercepted (fIPAR) by crops as a function of soil water content (0–200cm depth) close to silking (a), kernel number as a function of maximum fIPAR (b), and grain yield as function of kernel number (c) of maize crops cultivated at three landscape positions with three row spacings (0.38m, 0.52m, and 0.38m in a 2 × 1 skip-row pattern) during 2006/07 and 2007/08. Values are the mean of three plots at each row spacing x landscape position. Lines indicate the models fitted to data sets.
