“…They also investigated penetration resistance and soil temperature under NT and CT systems on silt loam in Pennsylvania. The results showed that the penetration resistance was signiWcantly higher in the soil surface of NT than in the CT system, which agree with other studies conducted in silt loam and loam soils in the Swiss midlands (Chassot et al 2001), loamy sand soil in South Carolina (Busscher and Sojka 1987;Busscher et al 1986), sandy loam in Atlantic Canada, Hungary, Australia, and Argentina (Carter et al 2002;Fabrizzi et al 2005;Laszlo and Gyuricza 2004;Ratonyi et al 2005). The results of Duiker et al (2006) also showed a decreased average surface soil temperature in NT compared with CT which primarily resulted from diVerences in maximum temperature instead of minimum temperature.…”

“…The bulk density mainly depends on the mineral make up of soil and the degree of compaction. Many studies showed higher bulk density in the topsoil of NT compared with CT on diVerent soil type (Chassot et al 2001;Dam et al 2005;Duiker et al 2006;Fabrizzi et al 2005;Laszlo and Gyuricza 2004;Monneveux et al 2006), however, the results from Franzluebbers et al (1995) showed that bulk density was reduced shortly after tillage, but increased to levels observed under NT during both wet and cold intervals in the fallow period and during the growing season in all crops tested (Franzluebbers et al 1995). Duiker et al (2006) suggested that the rate of reconsolidation may depend on soil physical structural and texture, rainfall, and post-tillage traYc intensity.…”

Do different production environments justify separate maize breeding programs?

et al. 2009

DiVerent production environments are being adopted by farmers. Therefore, allocation of resources to breeding research that targets diVerent production environments should be continuously assessed. Agronomists should conduct extensive hybrid £ production environment interaction research before recommending breeders to conduct separate breeding programs for each production environment. The lack of interactions between genotypes and production environments (e.g., tillage) would not justify conducting separate breeding programs and duplicating breeding resources. On the other hand, separate breeding programs would be necessary if cultivar rankings diVer. The purpose of this paper is to review the available literature on experiments designed to test genotype £ tillage interactions (GT) in maize (Zea mays L.). No-till system (NT) and conventional till system (CT) were utilized as examples of diVerent production environments. The majority of experiments reviewed showed that there is no need to develop cultivars speciWc to NT because the cultivars that were developed under CT systems performed relatively the same under NT. The magnitude of GT interactions found was very small to expect better cultivars from breeding under NT. Additional research is needed to conWrm these conclusions, especially when applied to other production environments (e.g., development of cultivars under organic conditions). Scientists should evaluate genotype by tillage interactions before investing additional resources in breeding for those speciWc target environments. Top yielding genotypes seem be consistent across years, locations, inputs; and most of the present evidence suggests that breeding for speciWc till systems is not necessary.
