The response of grain yield to narrow rows can be analyzed in terms of the effect on the amount of radiation intercepted by the crops. The objective of this work was to study the effect of row spacing on grain yield and radiation interception (RI) during the critical period for grain set in three crop species. Ten experiments were conducted with maize (Zea mays L.), sunflower (Helianthus annuus L.), or soybean [Glycine max (L.) Merr.] under irrigation or under dryland conditions without severe drought during flowering and grain filling. The treatments consisted of two row distances combined with other factors such as plant density, cultivar, defoliation, etc. Grain yield responses to decrease distance between rows were inversely proportional to RI achieved with the wide-row control treatment during the critical period for grain number determination (r 2 = 0.62, 0.54, and 0.86 for maize, soybean, and sunflower, respectively). Moreover, when row spacing was reduced, grain yield increases and RI increases during the critical periods for grain set were significantly and directly correlated in the three crop species (r 2 = 0.71, 0.64, and 0.94 for maize, soybean, and sunflower, respectively). For the conditions of these experiments, grain yield increase in response to narrow rows was closely related to the improvement in light interception during the critical period for grain set.

Twin Rows Minimally Impact Irrigated Maize Yield, Morphology, and Lodging (2013, background): “0 or greater for all treatment combinations suggesting that 95% or greater solar radiation interception occurred during the critical period around silking and early grain fi ll (Andrade et al., 2002) and had little infl uence on grain yield.”
Row Width and Maize Grain Yield (2006, background): “The rate of increase in grain yield per unit increase of light interception at silking under narrow rows was less than one (Andrade et al., 2002), which suggested reduced RUE in narrow rows as compared to wide rows.”
Ecophysiological Yield Components of Maize Hybrids with Contrasting Maturity (2007, background): “The area is characterized by low average temperatures during the growing season (17.8jC) and a frost-free period of about 150 d.

Responses of Maize Hybrids to Twin-Row Spatial Arrangement at Multiple Plant Densities (2012, background): “Decreasing row spacing at equal plant density promotes more equidistant plant spacing, theoretically reducing plant-toplant competition, while improving plant resource capture and utilization (Duncan, 1984; Andrade et al., 2002; Barbieri et al., 2008) and decreasing weed competition through earlier ”
