Sowing date and fungicide application in the agronomic performance of oleaginous brassica for the biodiesel production

Abstract

Sowing date and fungicide application in the agronomic performance of oleaginous brassica for the biodiesel production 1 This work aims to evaluate the agronomic performance of crambe and juncea canola, sowed in the summer and winter season intervals with and without fungicide application. The cultivars used were FMS Brilhante and Terola 25A85 for crambe and juncea canola, respectively. The experimental design was randomized blocks in split plots, in which the plots were sowing dates 15 th May (E1), 1 st June (E2) and 15 th June 2014 (E3), and the split plots with and without aboveground part with fungicide (trifloxystrobin 150 g L-1 + prothioconazole 175 g L-1). The evaluated variables were plant height, thousand seed weight, seed yield, oil content and oil yield. The sowing dates had had influence only on plant height for crambe, while juncea canola had a significant effect on plant height, seed yield and oil yield. The fungicide application gave higher seed yield for crambe and for juncea canola, higher thousand seed weight, seed yield and oil yield. With the production technologies adopted for the growth of these two brassicas, it is necessary to obtain higher yields of seeds and oil, to enable the commercial exploration in the interval between the summer and winter off-season in the Northern region of Paraná state, Brazil

Herbaceous Oil Crops, a Review on Mechanical Harvesting State of the Art

“…After a period of decreasing attention on crambe in European Union [13], mostly due to significant yield variability [199], establishment difficulties linked to low germination energy, capsule persistence, seed dormancy [200,201], and poor interest of crambe cake for animal feeding [202]; in the last year there has been growing interest toward this species, as demonstrated by several European projects [203]. The renewed attention to this crop is related to several factors: low degree days requirement (about 1600) to reach maturity and so feasibility for double cropping [204][205][206], drought resistance, adaptability to various soil pH values, no seed shattering, higher dimension of the seed if compared to other oil crops [13], and plant height suitable for mechanical harvesting [207]. Moreover, crambe cultivation shows lower environmental impact than major oil crops, like, for example, canola [208].…”

Optimization of agricultural practices for crambe in Europe

“…Taken together, these characteristics make crambe cultivation possible even in marginal land, avoiding the competition for arable land currently used for food production (Von Cossel et al, 2019). Despite its adaptability, crambe seed and oil yield can be highly influenced by environmental conditions (Reginato et al, 2013;Zorzenoni et al, 2019), thus limiting the potential scale up of this oilseed crop. As reported by Falasca et al (2010) frost damage can occur at seedling stage when temperature falls below -5°C.…”
