“…Due to the relevance of oat cropping, several studies (Bortolini et al 2005;Floss et al 2007;Arlauskienė et al 2011;Fontaneli et al 2012;Guerreiro and Oliveira 2012;Meinerz et al 2012;Siloriya et al 2014;Zorovski et al 2014;Hawerroth et al 2015;Mantai et al 2015) have been performed. These researches aimed to improve the knowledge and instigate increased grain yield.…”

“…Researches analyzing grain yield have been developed with sizes of plot useful areas and number of replications of, respectively, 0.15 m 2 and 3 (Meinerz et al 2012), 2 m 2 and 3 (Floss et al 2007), 3 m 2 and 4 (Mantai et al 2015), 3 m 2 and 4 (Hawerroth et al 2015), 5 m 2 and 6 (Guerreiro and Oliveira 2012), 10.5 m 2 and 3 (Zorovski et al 2014), 12 m 2 and 4 (Siloriya et al 2014), 12 m 2 and 3 (Bortolini et al 2005), 23.8 m 2 and 4 (Fontaneli et al 2012), and 30 m 2 and 3 (Arlauskienė et al 2011). Inadequate plot size and number of replications can increase the experimental error and the inferences regarding the treatments can be inaccurate (Banzatto and Kronka 2013).…”

The objectives of this study were to determine the optimum plot size (Xo) and the number of replications to evaluate grain yield and verify the variability of Xo among oat cultivars. Thirtytwo uniformity trials of 3 × 3 m were performed, being 8 from each cultivar (URS Charrua, URS Taura, URS Estampa, and URS Corona). Each uniformity trial was divided in 36 basic experimental units (BEU) of 0.5 × 0.5 m. Grain yield was determined in each BEU. The Xo was determined by the method of maximum curvature of the coefficient of variation model. Mean comparisons among cultivars were performed by the Scott-Knott test via bootstrap. The number of replications was calculated by an iterative process until convergence for experiments in completely randomized design (CRD) and randomized block CRop pRoduCTion And MAnAgeMenT-Article

“…At HPS in 2018, we observed that as oat biomass production increased, there was less weed biomass present in the total biomass. Cover crops, including cereal grains, have been shown to suppress weed pressure (Begna et al., 2011; Hauggaard‐Nielsen, Ambus, & Jensen, 2001), but the competitive advantage of cereal grains to reduce weed biomass is influenced by stand density and cereal forage biomass production (Arlauskiene, Sarunaite, Kadziuliene, Deveikyte, & Maiksteniene, 2014; Petrosino, Dille, Holman, & Roozeboom, 2015). While the use of forages for weed suppression was not directly planned in the objectives of the current study, our results support other research conclusions and suggest that as the proportion of spring pea in the total biomass increased in the forage mixtures there was less ability for the forage to outcompete and reduce weed biomass in situations with heavy weed pressure.…”

Influence of oat and spring pea mixtures on forage characteristics in different environments

et al. 2020

Forage mixtures including oat (Avena sativa L.) and spring pea (Pisum sativum L. spp. sativum) provide opportunities to optimize forage production with increasing forage quality, relative to single species stands. Under different climate scenarios, adjusting seeding rates of these mixtures may produce variable results in forage quantity and quality. We conducted a 2-yr study at three study sites to evaluate forage characteristics within mixtures of oat and spring pea stands across a semi-arid to subhumid precipitation gradient. At the western-most and driest location (219 mm March-June precipitation), the oat monoculture produced 16−19% more total biomass than seeding treatments with mixtures of oat and spring pea. In contrast, at the moderate-precipitation site (255 mm precipitation), no differences in total biomass were detected for the oat monoculture and seed mixtures of oat and spring pea. Large variation at the wettest site (339 mm precipitation) limited our ability to detect differences for total biomass production across treatments, but weed pressure in Year 2 of the study reduced forage production. Typically, crude protein (CP) concentration decreased linearly (P < .01) as spring pea decreased in the seeding rate, but CP concentration and total CP yield varied for the seeding rate treatments at the different study sites. Environmental condition may influence the benefit of substituting spring pea into a properly managed oat forage crop to increase forage quality. The contribution of spring pea forage in the total forage biomass of mixtures may be limited, especially in drier conditions.

“…Lundkvist et al [23] and Sinchana et al [39] indicated that including peas in a crop rotation increased the risk of weed problems in the long term. The cultivation and agrotechnics of grain legumes are very close to those of cereals and are favorable for the spread of the same weed species [4]. This fact indicates that crop type modulates weed community composition and diversity [44].…”

Background In organic crop farms, growing crop yields are limited by insufficient nitrogen supply to plants and crop weediness. In such farms, legume swards are proposed as a service crop to improve nitrogen cycling. However, a positive effect of nitrogen is not only on cereals but also on weeds. In crop rotation, legume swards can stimulate the competition of cereals using the above-ground mass of legume to control the spread of weeds. The effects of the following methods for weeds control were analyzed: (i) forage legumes (Trifolium pratense L. and T. repens) undersown in cereals, (ii) forage legumes (T. pratense L., Medicago sativa L.) and their mixture with festulolium (x Festuliolium) and their above-ground mass management methods, and (iii) plant-based fertilizers (red clover above-ground mass fermented and composted). Results Oat with red clover undersown reduced weediness more than red clover monocrops, pea, and their mixture with oats. Incorporated undersown white clover mass increased spring barley competitiveness with weeds. When growing legume swards for a longer period of time (green fallow), red clover and their mixture with festulolium are the most suitable for this purpose. The lowest weed dry weight (average 34%, compared with the removal from the field) was obtained while using the mixed management. The cultivation of cereals after forage legumes and their mixtures with festulolium (as a preceding crop) increases its grain yield and competitive ability against weeds. Fermented red clover and fermented pea and spring wheat mixture mass, as a manure, did not increase weediness. Conclusions It was concluded that the effectiveness of the perennial forage legumes is determined by the uses of the above-ground mass: soil cover, mulching, application of green manure, and intensity of mass mineralization. Type of activity of forage legumes on weeds were competition for environmental resources, disruption/promotion of germination, destruction of above-ground mass, reduction of the amount of matured seeds, creation of a physical barrier (mulch), and increase of competitiveness of cereals. Growing forage legumes in pure crops usually leads to a loss of marketable production. Graphic abstract
