“…Minimum tillage treatment can be suitable for high density crops (Kisic et al, 2010) and parallel can give greater soil strength and quality in order to solve soil erosion problems, mitigate the climate harms and reduce energy consumption (Holland, 2004). However, there has been a discordance in the research on the responses of various oilseed crops to tillage system with lower yields have been reported under conventional tillage compare to minimum (Bilalis et al, 2010;Abdullah, 2014;Seddaiu et al, 2016) as well as higher yields under conventional tillage (Kasap and Coskun, 2006;Torabi et al, 2008) and little effect of tillage treatment on yield (Hocking et al, 2003). Taking in account this variance it could be concluded that the interaction between the tillage method and the environment is more important that the tillage method alone (Rasmussen, 1999;Roper et al, 2013).…”

The importance of Camelina sativa has lessened substantially over the last half century, however its unique oil composition and the beneficial agronomic attributes with regard to sustainable agriculture have recently reignited interest in this oilseed crop. Notwithstanding the great interest in camelina, the potential to be cultivated organically has not received prominent attention from researchers. The objective of this study was to evaluate the response of organic camelina to different tillage systems and compost types, based on differences in yield parameters, oil content, seed crude protein and fatty acid profile. The field experiments, conducted during the 2014, 2015 and 2016 growing seasons, were laid out in a split plot design with three replicates, two main plots (conventional tillage and minimum tillage) and three sub-plots (vermicompost, compost, unamended control). It is consequential from the results that the effect of the type of organic amendment was highly significant on camelina’s productivity. Particularly, compost treatment resulted in higher seed and oil yield (1132 and 446 kg ha-1, respectively) compared to the vermicompost (682 and 269 kg ha-1, respectively) and the unamended control (554 and 220 kg ha-1, respectively). Regarding the fatty acid profile, both organic amendments increased linoleic and palmitic acids, while they presented disparate effects on a-linolenic acid. Furthermore, tillage system influenced significantly only thousand seeds weight, protein content and gondoic acid, enabling the use of reduced tillage to be comparably effective on organically grown camelina performance. Further experimentation is needed to match crop needs with the appropriate cropping techniques in order to ensure an effective organic cultivation.

Sunflower (Helianthus annuus L.) is a major oilseed crop grown for its edible oil across the globe including Pakistan. In Pakistan, the production of edible oil is less than the required quantity; the situation is being worsened with the increasing population. Thus, there is dire need to grow those sunflower genotypes which perform better under a given set of agronomic practices. In this 2-year study, we compared four sunflower genotypes, viz., Armoni, Kundi, Sinji, and S-278 for their yield potential, oil contents, fatty acid composition, and profitability under three sowing methods, viz., bed sowing, line sowing, and ridge sowing and two tillage system, viz., plow till and minimum till. Among the sunflower genotypes, the genotype Armoni produced the highest plant height, number of leaves, head diameter, 1000-achene weight, and achene yield; the oil contents and oleic acid were the highest in genotype Sinji. Among the sowing methods, the highest number of leaves per plant, head diameter, number of achenes per head, achene yield, and oil contents were recorded in ridge sowing. Among the tillage systems, the highest head diameter 16. 2 cm, 1000-achene weight (57.2 g), achene yield (1.8 t ha), oil contents (35.2%), and oleic acid (15.2%) were recorded in minimum till sunflower. The highest net benefits and benefit to cost ratio were recorded in minimum till ridge sown Armoni genotype. In conclusion, the genotype Armoni should be grown on ridges to achieve the highest achene yield, oil contents, and net profitability.
