“…The receipt of heavy rainfall of 919 mm during 2013 resulted in robust growth of castor in the second year. In contrast, Soratto et al (2012) reported taller plants with wider plant geometry. The probable reason for such positive response due to wider geometry might be sufficient rooting and moisture extraction pattern which helped better absorption of water and nutrients.…”

“…There are many reports on the effects on seed oil content from year-to-year variation, contrasting environments, and agronomical practices like fertilization, plant spacing, irrigation, and planting date (Anastasi et al, 2015;Anjani, 2010;Biscaro et al, 2012;Diniz et al, 2009;Koutroubas et al, 2000;Lima et al, 2015;Patel et al, 2012;Ramanjaneyulu et al, 2013;Severino et al, 2006;Severino and Auld, 2013a;Soratto et al, 2011Soratto et al, , 2012Souza et al, 2007;Souza-Schlick et al, 2011, 2014. Most reports confirm that environmental factors do not influence the oil content in castor seed.…”

“…After collection, seeds were air dried for two weeks at room temperature and then weighed. For the calculation of seed yield in kg per ha a spacing of 40 × 40 cm was considered including 62,500 plants per ha which is normal for castor or sunflower plantations [24,25]. Samples of seeds were sent to the lab of the Technical University of Crete for oil and biodiesel extraction.…”

Abstract:The effects of plant species (castor bean (Ricinus communis L.) versus sunflower (Helianthus annus L.)) and irrigation regime (freshwater versus secondary treated municipal wastewater) on soil properties and on seed and biodiesel yield were studied in a three year pot trial. Plant species were irrigated at rates according to their water requirements with either freshwater or wastewater effluent. Pots irrigated with freshwater received commercial fertilizer, containing N, P, and K, applied at the beginning of each irrigation period. The results obtained in this study showed that irrigation with effluent did not result in significant changes in soil pH, soil organic matter (SOM), total kjeldahl nitrogen (TKN), and dehydrogenase activity, whereas soil available P was found to increase in the upper soil layer. Soil salinity varied slightly throughout the experiment in effluent irrigated pots but no change was detected at the end of the experiment compared to the initial value, suggesting sufficient salt leaching. Pots irrigated with effluent had higher soil salinity, P, and dehydrogenase activity but lower SOM and TKN than freshwater irrigated pots. Sunflower showed greater SOM and TKN values than castor bean suggesting differences between plant species in the microorganisms carrying out C and N mineralization in the soil. Plant species irrigated with freshwater achieved higher seed yield compared to those irrigated with effluent probably reflecting the lower level of soil OPEN ACCESSWater 2011, 3 1113 salinity in freshwater irrigated pots. Castor bean achieved greater seed yield than sunflower. Biodiesel production followed the pattern of seed yield. The findings of this study suggest that wastewater effluent can constitute an important source of irrigation water and nutrients for bioenergy crop cultivations with minor adverse impacts on soil properties and seed yield. Plant species play an important role with regard to the changes in soil properties and to the related factors of seed and biodiesel yields.
