Technological Aspects of Rye Cultivated in the Conditions of Sandy Soils in Southern Oltenia

Abstract

Rye (Secale cereale L.) is an important crop in Europe, where it occupies about 90% of the world's area cultivated with this cereal (FAOSTAT, 2018), mainly in the countries of Central and Eastern Europe. The main research highlights the mechanisms of adaptation of rye culture to climate change, aimed at identifying genotypes that have a good behavior in culture under conditions of abiotic (thermohydric) and biotic stress (pathogens and pests) in order of restoring the production capacity and protection of agroecosystems in the area of sandy soils by promoting in culture some genotypes tolerant to thermohydric stress. In the two experimented years of 2020 and 2021 the obtained results prove the new genotypes promoted on the market had a higher capacity of production than the Control (Suceveana variety), with an average yield of over 4555 kg/ha registered at Serafino genotype in the conditions of a sandy soil with a low natural fertility, poorly supplied with total nitrogen (0.05- 0.07%). In average, during the tested years, the attack frequencies of pests manifested in the comparative rye culture, as well as the attack intensities did not show significant differences from one variety to another, significant differences compared to the control variety (Suceveana) being observed only in the case of Serafino variety.

Influence of harvest time on carbohydrates content of Jerusalem artichoke (Helianthus tuberosus L.) tubers

“…The research was carried out on the Agricultural Research Development Station Caracal, using three cultivars of Jerusalem artichoke: Dabuleni, Rares and Dacic. Into the experiment we apply the specific technology described in previous published research papers [23]. All cultivars were grown under the same environmental and agricultural conditions.…”

“…Jerusalem artichoke is a plant without special requirements, well adapted to the climatic conditions with very good production without special technologies [23]. The tubers can be harvested in the fall or left underground until spring.…”

The potential of rhizobacteria to control soil-borne fungal pathogens in tomato

“…Reynolds et al (2003), bitki ile toprak kaynaklı mikroorganizma etkileşimlerinin, bitki sistemi kompozisyonu ve dinamiklerinin itici güçleri olarak tanımlamıştır. Toprak kaynaklı mikroorganizmaların toprak oluşum süreçlerine dahil olduğu, toprağın ayrışmasına, humus oluşumuna ve topraktaki bitki patojenlerinin gelişiminin kontrol altında tutulmasına önemli katkı yaptığı bildirilmiştir (Weller et al, 2002;Matei et al, 2017). Toprak ile yakın ilişkili olan rizobakteriler, bitki hastalıklarına karşı geniş spektrumlu biyokontrol aktivite göstermektedir (Liu et al, 2017).…”

Climate Change and Rye (Secale cereale L.) Production: Challenges, Opportunities and Adaptations

“…Novel genotypes, notably the Serafino variety, exhibit heightened production capacity and tolerance to sandy soil conditions, emphasising their potential for enhanced agroecosystem protection (Matei et al. 2021). The impact of climate change on extreme weather and crop productivity fluctuations highlights the potential of double‐cropping systems (DCSs).…”
