“…From an applied research standpoint, corn tillers had no adverse effects on yields, regardless of all factors evaluated. This agrees with data presented by Earley et al (1971) and Sangoi, et al (2012b), who identified tillers as irrelevant to yield outcomes. Similarly, Sangoi et al (2009) found tiller presence increased yields by 12% (1.1 Mg ha -1 ) across genotypes and plant densities (40000 and 70000 plants ha -1 ).…”

“…While tillers add competition for plant resources, nutrients and photosynthates can be translocated from tillers to main stalk, depending on tiller sink size (Alofe & Schrader, 1975;Dungan, 1931;Russelle et al, 1984). In previous studies, corn tiller presence has resulted in neutral (Earley et al, 1971;Frank et al, 2013;Sangoi et al, 2012b), positive (Hansey & de Leon, 2011;Lyon, 1905;Sangoi et al, 2009;Williams, 1912), and negative (Frank et al, 2013;Hansey & de Leon, 2011) effects on yields. In addition, tiller contribution to corn yield has been linked to plant density (Akman, 2002;Hansey & de Leon, 2011), genotype (Akman, 2002;Sangoi et al, 2009), and growing environment (Markham & Stoltenberg, 2010;Williams, 1912).…”

“…Tillering is a form of phenotypic plasticity in corn. Thus, its expression depends on genotype (Hansey & de Leon, 2011; Sangoi, Schmitt, Vieira et al., 2012; Tokatlidis et al., 2005) and the availability of resources (Gardner, 1942). Lower daily average temperatures increase the number of tillers in corn, particularly when combined with higher light intensities (Markham & Stoltenberg, 2010; Stevenson & Goodman, 1972; Tetio‐Kagho & Gardner, 1988).…”

“…According to [33], tillers emergency may lead to soil water depletion and resulted in less available water for the kernel formation. In fact, their formation is a genetic heritage of Teosinte domestication into Maize [34] and they are not considered to affect stalk development when water or nutrients are not limiting [35,36]. However, it can be a major concern in dryland condition or under low plant density [35,37].…”

Maize is a crucial global commodity, which is used not only for food, but also as an alternative crop in biogas production and as a major energy-supply ingredient in animal diets. However, climate change is jeopardizing current maize production due to its direct impact on weather instability and water availability or its indirect effects on regional climate suitability loss. Hence, new areas for sweet maize cultivation should be considered in the future. Therefore, this study focuses on the possibility of producing maize in a challenging environment in Southern Italy considering rainfed cultivation and two irrigation regimes (full and deficit). The experiment was conducted during two subsequent growing seasons under semi-arid Mediterranean climate conditions. The overall results indicated a significant difference in biomass and yield between irrigated and non-irrigated treatments, and between full and deficit irrigation. Sweet maize cultivated under deficit irrigation gained less biomass than under full irrigation and its development and fruit maturation were delayed. Under deficit irrigation, the plants gave lower yields and a higher percentage of the panicle weight consisted of kernels. Irrigation water productivity was higher for deficit than for full irrigated treatment. These findings indicate the feasibility of sweet maize production in semi-arid areas of Southern Italy using adaptive agricultural strategies including deficit irrigation and controlled water stress. Given the importance of maize production, understanding of maize growth and productivity in a challenging environment may support future agricultural programming and thereby contribute e to mitigation of the direct and indirect effects of climate change.

Contribution of tillers to maize yield stability at low plant density

One of the main challenges of using low plant densities in restrictive and variable environments is to maximize the use of resources in better‐than‐expected years. In this context, tillering could be an alternative to increase reproductive and vegetative plasticity. The objectives of this study were to (a) characterize the correlation between environmental conditions, tiller traits, crop grain yield, and grain yield advantages due to tillers; (b) determine the grain yield response to tillering (i.e., grain yield difference between tillered and nontillered crops) for a wide range of environments; and (c) to evaluate the effect of tiller presence on grain yield of the main shoot, considering its effect on the apical and subapical ears. Tillered and nontillered crops were evaluated under rainfed conditions during two seasons (2018–2019 and 2019–2020). These experiments were carried out at 11 sites in the southern Argentinean Pampas, varying sowing date (22 Oct. to 5 Dec.), plant density (2–3 plants m−2), genotype (AX7784 and AX7761), and soil depth. Grain yield (3.2–11.9 Mg ha−1) was correlated with tillers productivity, mainly explained by postflowering precipitations. The contribution of tillers to grain yield was more proportional than their consequent yield depression at the main shoot. Tillers either increased (3 sites) or maintained (8 sites) grain yield, and their contribution increased as the environment improved without any detrimental effect in the most restrictive environments. Tillering has the potential for increasing resource (radiation, water, nitrogen) use efficiency under low plant density strategies adopted for restrictive environments.
