ANALYSIS OF GENOTYPE-BY-YEAR INTERACTION FOR Secale cereale L. PRODUCTIVE TRAITS AND CIRCULAR ECONOMY

Abstract

The circular economy offers a new product-waste-product model, in this case obtaining biofuels from rye biomass. The circular economy introduces a new product design, which will enable its functionality for a longer period of use. Secale cereale L. is an economically important crop for food, feed and bioenergy. The objective of this study was to estimate productivity of rye genotypes and the possibility of obtaining biogas from rye biomass during two growing seasons, 2019-2020. The aim of this study was to examine the influence of year and genotype on rye productivity parameters, biogas, methane yield, methane proportion, and the possibility of using rye as an alternative fuel in Serbia. The influence of the year and genotypes on the parameters of rye productivity, biogas and methane yield, methane content and the possibility of using rye as an alternative fuel in Serbia was investigated. Genotype and year × genotype interaction had a statistically significant effect on biogas yield, methane yield and methane content in the studied rye genotypes. Genotype G1 had the mean of green biomass yield (25.73 t ha -1 ) significantly higher compared to genotype G2 (23.75 t ha -1 ) in both years of experiment. Green biomass yield (24.11 t ha -1 ) was better in 2019 compared to 2020. Biogas yield varied from 260.57 m 3 ha -1 (genotype G1) to 214.58 m 3 ha -1 (genotype G2). Biogas yield were better in 2019

Toward an Environmentally Friendly Future: An Overview of Biofuels from Corn and Potential Alternatives in Hemp and Cucurbits

“…turbinata 2.63-6.80%. Ikanović et al [86] mention that seeds constitute approximately 10% of the total fruit mass, with cucurbits seed yields ranging from 600 to 1000 kg ha −1 , while in the study by Sure et al [89], seed yields ranged from 400 to 1686 kg ha −1 . According to Berényi [90], cucurbits seed yields range from 800 to 1000 kg ha −1 .…”

“…Cucurbitaceae is a plant family comprising approximately 115 genera and over 960 species, exhibiting variations in shape, size, color, and taste [84]. Primarily, cucurbits fruits of various ripeness stages are utilized (Figure 4a), and their flesh is employed to create various dishes such as soups, salads, roasted and boiled dishes, pickled, fermented, and dried products [85,86]. As a byproduct of cucurbits processing (e.g., in juice production), a significant number of seeds often remains, which constitutes waste.…”

“…Ibeto et al [98] emphasized that the clarity of oil is advantageous as biodiesel feedstock compared to oils that are very dark in color. Ikanović et al [86] reported that cold-pressed oil from cucurbit seeds is dark green with a red fluorescence. Karaye et al [99] reported light yellow oil from seeds of Cucurbita pepo and dark brown oil from Lagenaria breviflora.…”

ECONOMICALLY SIGNIFICANT PRODUCTION OF Secale cereale L. AS FUNCTIONAL FOODS

“…The introduction new of breeding programs for stress conditions will increase in the world. Areas have been increasing in recent years, both due to the interest of rye in organic production, production on acidic soils, and also due to the growing interest in biofuel production (Ikanović et al, 2022).…”
