Crop management should be determined to reintroduce ancient wheat. This study aimed to determine: i. the response of the yield of ancient wheat on sowing density; ii. the impact of sowing density on plant health, weed infestation and pest occurrence. Field experiments were carried out in Poland, on three organic farms. The factors were: (1) wheat species: Persian wheat (Triticum persicum Vav.) and Indian dwarf wheat (T. sphaerococcum Perc.), (2) sowing density (400, 500, and 600 grains m⁻²). Increasing the sowing density of T. sphaerococcum from 400 to 600 grains m⁻² increases the grain yield and reduces the pest pressure (Oulema spp. and Aphididae). Sowing densities did not affect the severity of powdery mildew at stem elongation as well as root rot and eyespot at the development of fruit. At the highest sowing density, the leaf area with tan spot symptoms was the highest. The eyespot symptoms occurred more frequently and the damaged plant surface caused by Oulema spp. was larger on T. sphaerococcum. Persian wheat turned out to be more susceptible to weed infestation. Indian dwarf wheat and Persian wheat are useful for organic farming, and the sowing density should be 500 or 600 grains m⁻² and 400 grains m⁻², respectively.

The aim was to investigate the impact of an automatic in ovo injection of the raffinose family oligosaccharides (RFO) extracted from the seeds of Lupinus luteus L, on the chicken performance and resistance in a production environment. At day 12 of incubation, a total of 57,900 eggs (Ross 308) were divided into two groups: 1/ Control, injected with 0.9% NaCl and 2/ RFO group, injected with 1.9 mg/egg of the lupin seed extract, dissolved in 0.2 mL NaCl. The performance parameters, biochemical indices (lipid profile, hepatic parameters), gut histomorphology and duodenum structure, oxidative stability of the meat and microbiological counts of the major commensal microbiota species were analyzed. Mortality, body weight, and feed conversion ratio (FCR) were not affected. By day 42, several health indices were improved with RFO and were reflected in a beneficial lipid blood profile, increased villi surface and better combating opportunistic pathogens through reduction of Clostridia and decreased coccidia counts. The RFO increased meat oxidation, but only at the beginning of the storage. The RFO sourced from local legumes can be considered a promising prebiotic for broiler chickens. In ovo delivery of prebiotics and/or synbiotics should be further optimized as an important strategy for the earliest possible modulation of chicken resistance.

The need for foods with high nutritional value has led to the rediscovery of ancient wheat species Triticum sphaerococcum and T. persicum as raw materials with valuable consumption properties, but their reintroduction requires assessment of their productivity under different agricultural practices. The field experiments were carried out for three years (2018–2020) to test the hypothesis that the sowing density of T. sphaerococcum and T. persicum (400, 500 and 600 no m⁻²) will affect their agronomic traits, yield and occurrence of diseases, but the response will depend on the hydrothermal conditions of the growing seasons. In this study, a significant correlation of the grain yield with the amount of precipitation in tillering, and from booting to the beginning of fruit development was demonstrated. The sowing density of T. sphaerococcum had an impact on the grain yield only under moderate drought stress during the growing season (2019), when the highest yield was obtained at a sowing density of 600 m⁻². In 2019, the most favorable sowing density was also the highest for T. persicum. In the year with the lowest amount of rainfall during the growing season (2018), the yield of T. persicum was the highest in the lowest sowing density. At the shooting stage, a greater intensity of powdery mildew was observed on T. persicum, especially with higher sowing densities. Increasing the sowing density also increased the occurrence of root rot symptoms in both wheat species in the year that favored the occurrence of this disease (2018). It can be concluded that in the integrated low-input cultivation of T. sphaerococcum and T. persicum, it is justified to use a sowing density of 600 pcs. m⁻², in an agroclimatic zone with moderate droughts during the growing season.

In this study the oribatid mite communities of conventional and organic vineyards in theValencian Community (Spain) were compared. The soil samples were collected in El Poble Nou de Benitatxell in autumn 2014 and spring 2015 from four sites, treated as replicates, each including a conventional vineyard, an organic vineyard, and a control (natural habitat, i.e. in plots 1-3 an abandoned vineyard, in plot 4 an area never used in agriculture). Two parallel samples were collected in each vineyard from a zone between vine rows, driven by a tractor (Tr), a zone between vines (Vi), the border of the vineyard (Bo) and from a control, making a total of 112 samples. In total 3,225 oribatid mites were obtained represented by 59 species. No differences were found in density of Oribatida between the conventional, organic vineyards and the control, but the species diversity was higher in the control than in the vineyards. In the vineyards the density and species number of the oribatid mites were highest between vines (the average from all vineyards and both seasons was 4,400 individuals per 1 m2, 15 species), followed by the border of the vineyards (2,800 individuals per 1 m2, 14 species) and were lowest between vine rows (400 individuals per 1 m2, 6 species). The species diversity of Oribatida was higher in autumn than in spring, while the density followed this pattern only in the vineyards, but not in the control. In the vineyards Oribatula excavata dominated (D = 25), followed by Minunthozetes quadriareatus and Passalozetes africanus (D = 18 and 14, respectively), while in the control these species were not abundant. In the control the most abundant species was Oppiella subpectinata (D = 28), followed by Eremulus flagellifer (D = 20). Podoribates longipes and Steganacarus boulfekhari are reported for the first time in Spain. To conclude, the oribatid mites did not benefit from the organic cultivation of the vineyards, probably because they are tolerant to herbicides used in the conventional systems but sensitive to mechanical cultivation of soil, which was even more intense in organic vineyards than in the conventional ones.
