Sugar Beet (Beta vulgaris L.) Yields and Potential for Bioethanol Production under Irrigation Regime

Abstract

The current study was carried out to analyse three sugar beet genotypes regarding to the economic yield and the potential to produce bioethanol, under the influence of furrow irrigation regime in specific conditions of Transylvanian Plain, North-West Romania. The research factors, genotype (‘Leila’, ‘Clementina’ and ‘Libero’) and irrigation regime were studied within a polyfactorial experimental design. The results obtained indicated that in specific climatic conditions of Transylvanian Plain, ‘Libero’ genotype had a great performance and produced the highest yields. The average production of ‘Libero’ genotype was superior than ‘Clementina’ and ‘Leila’ varieties, both in irrigated and non-irrigated conditions, as it follows: 38.98 t ha–1, respectively, 52.72 t ha–1 in the first year of research; 47.63 t ha–1, respectively, 59.73 t ha–1 (in the second year); 2014-60.87 t ha–1, respectively, 74.43 t ha–1 (in the third year). Moreover, the production increased with 11.5% under irrigated conditions for all the studied genotypes. The results also revealed the positive influence of the irrigation regime on the qualitative parameters of the bioethanol (ethanol, higher saturated monoalcohols, methanol, water, inorganic chloride, cooper, phosphorous, sulphur etc.) indicating that the obtained bioethanol might be a viable alternative for fossil fuels.

Genome-wide identification, evolution, and role of SPL gene family in beet (Beta vulgaris L.) under cold stress

“…Sugar beet ( Beta vulgaris L., 2n = 18) is an economically important crop grown in temperate and cold temperate regions and is the raw material for approximately 30% of the world’s sugar [ 1 ]. Sugar beet is also an important raw material for bioethanol and animal feed worldwide [ 2 – 3 ]. According to previous research, sugar beet originated from a halophyte known as Beta maritima L [ 4 ]..…”
