Biodiesel Production from Sunflower in Greece

Abstract

This paper regards research for evaluation of the effect of the surface and subsurface drip irrigation method in the production of biodiesel from sunflower crop and in the saving of irrigation water, and in economic performance which directly concerns the Greek producers. The research was conducted in the Central Greece, in a field in the Farm of the University of Thessaly. The following treatments were organized: a) the surface (AUTO (E)) and b) the subsurface (AUTO(Y)) drip irrigation method, in which the irrigation was scheduled by an automatic evaporation pan. The research concerns the growing seasons of the years 2011 and 2012.

Effect of Irrigation Dose Based on Vegetation Indices Calculation Using Multispectral Sensor

“…This result is significant and predictable as the crop water needs in the I-50 treatment were covered by only 50% compared to the actual maize water needs (100% of the I-100), while dry biomass production was quite high. The results are consistent with those in previous researches (Papanikolaou & Sakellariou, 2012;Karatassiou et al, 2016aKaratassiou et al, , 2016b.…”

“…However, the difference between the I-100 and the I-75 treatment is 13% while the difference between the I-75 and I-50 is 30% which means that the dry biomass is more sensitive to deficit irrigation than plant height. The results for both plant height and the dry biomass production are consistent with those in previous researches (Papanikolaou & Sakellariou-Makrantonaki, 2012;Sakellariou-Makrantonaki et al, 2009;Mygdakos et al, 2009;Karatassiou et al, 2016aKaratassiou et al, , 2016b.…”

“…The solution, in this case, is the use of renewable energy sources, such as biomass. Biomass can be used either as the raw material for solid fuels (pellets) or liquid fuel production (bioethanol) (Karatassiou et al, 2016a(Karatassiou et al, , 2016bPapoutsidakis et al, 2018).…”
