“…Grain yield and test weight were influenced only by cultivar. This concurs with the results of Weisz and Bowman (18) and Cox and Shelton (4) who state that cultivars performed similarly across tillage systems. Due to favorable growing conditions including low disease pressure, only ‘Sisson’ produced yields that were significantly lower than the highest yielding cultivar and the entire trial averaged slightly more than 71 bu/acre (Table 6).…”

Soft Red Winter Wheat Cultivar Response to Tillage in the Mid-Atlantic Coastal Plain

Current cropping systems in the Mid‐Atlantic Coastal Plain utilize no‐tillage seeding methods for corn and soybean, but no‐tillage small grain acreage is also increasing in this region. The objectives of this research were to evaluate soft red winter wheat cultivars for grain yield, test weight, and lodging across three tillage systems in the Mid‐Atlantic Coastal Plain. Five soft red winter wheat cultivars were grown under no‐tillage, reduced tillage, and conventional tillage in the Coastal Plain of Virginia from 2002‐2004. Grain yields for the site averaged 80, 60, and 71 bu/acre in 2002, 2003, and 2004, respectively. Grain yield and test weight was effected by tillage treatment only in 2002 when the lower yields and test weights under conventional tillage were likely due to a higher degree of lodging. There was no consistent influence of tillage treatment on any variety. High‐yielding cultivars performed similarly under conventional, reduced, and no‐tillage systems. Cultivar recommendations for the region should not be made separately on the basis of tillage system.

“…Site-to-site and year-to-year effects were also inconsistent with respect to relative yields of cultivars, indicative of the presence of a three-way interaction between site, year and tillage (Table 1). These results are consistent with those of Cox and Sheldon (1992) and Marantz (1989) for wheat. The significant interactions observed suggest that it would be necessary to conduct bar- Grand mean = 3921.0, R-squared = 0.8914, CV = 14.3%.…”

“…Therefore, tillage management influenced relative yield performance of the cultivars in the present study. Cox and Sheldon (1992) found similar effects in wheat, as did Marantz (1989), andFishbeck (1982). Flom et al (1986) observed significant tillage effects on barley, but not as pronounced an effect as the present study, and these authors did not show a significant genotype × environment interaction for yield.…”

Therrien, M. C. and Grant, C. A. 1998. Effect of tillage management on yield performance in barley. Can. J. Plant Sci. 78: 301-303. A 3-yr study was conducted to assess the effect of tillage management on relative yield performance of selected cultivars of barley. The experiment was located on two differing textures of orthic black Chernozemic soils over 3 yr. Relative yields differed significantly between cultivars within tillage systems, and between tillage systems, sites and years. All interactions were also highly significant. This suggests that barley variety performance trials should be conducted under the same tillage management system across sites and years and that significant interactions should be identified and mitigated, wherever possible. Failure to do so could lead to misidentification of high yield-performance cultivars and subsequent loss of economic opportunities to producers.Key words: Barley, tillage, interactions, yield response Therrien, M. C. et Grant, C. A. 1998. Effet du régime de travail du sol sur le rendement de l'orge. Can. J. Plant Sci. 78: 301-303. Une expérience de trois ans a été mise en place pour évaluer les effets du régime de travail du sol sur le rendement relatif de certains cultivars d'orge. L'expérience était réalisée pendant trois ans sur deux sols chernozémiques noirs orthiques de texture différente. Les rendements relatifs différaient significativement selon le cultivar, tant dans un même régime qu'entre les divers régimes de travail du sol et que d'un endroit et d'une année à l'autre. En outre, toutes les interactions entre ces variables étaient, elles aussi, hautement significatives au niveau statistique. Il appert donc que les essais de variétés d'orge devraient être réalisés dans les mêmes conditions de travail du sol, tous emplacements et années confondus, et que, dans la mesure du possibles les causes d'interaction significative devaient être atténuées, faute de quoi on risque de ne pas pouvoir dégager les cultivars vraiment supérieurs, avec les manques à gagner que cela peut représenter pour les producteurs.

“…grain quality is ranked according to the grain protein concentration. This is largely dependent on genotype (Johnson et al 1985;Stoddard and Marshall 1990;Colecchia et al 2012), but is also influenced by the complex interactions between nitrogen (N) and water availability, yield and temperature (Randall and Moss 1990;Cox and Shelton 1992;Troccoli et al 2000;Di Fonzo et al 2001;LopezBellido and Lopez-Bellido, 2001;Flagella 2006).…”

A 2-year conservation agriculture experiment was conducted in Southern Italy on durum wheat continuous cropping. Aim of the research was to assess the durum wheat productivity and grain quality in reduced soil tillage systems, according to conservation agriculture principles. The interactions among experimental treatments and climate revealed a close relationship among grain yield, grain quality and wheat growth conditions. Specifically, conventional tillage (CT, plowing and 2 disc harrowing) showed in the 2-year period higher grain production than reduced tillage treatments, minimum (MT, 1 disc harrowing) and No tillage (NT), especially for good crop water availability (3.29 t ha -1 of grain yield in CT, 2.67 in MT and 2.54 in NT). The amount of rainfall (above the average in both years) and its distribution in the growing seasons (more regular in the first year) strongly influenced wheat-grain quality indices (11.97% of protein content in the first year and 9.82% in the second one). Also, the wheat quality resulted more sensitive to the "Year × Tillage" interaction, with differences among tillages more evident in the second year and favourable to NT and MT. Spectral vegetation indexes (NDVI and TVI) measurements at flowering, have been shown to be useful to support farmers in N-late application for improving grain wheat quality. From this experiment carried out during the conversion period and in wet years, wheat managed with CT resulted in higher grain yield and quality, while only test weight showed a significant "Year × Tillage" interaction. Further indications emerged on the need to supply additional (10-20%) seed amount at sowing and crop nitrogen fertilizer in the first transition years in reduced tillage systems compared to conventional ones.
