The cultivation of oil crops for biofuel production has often been accused of not being environmentally sustainable due to the high inputs needed. To explore the effect of reduced input on productive and qualitative traits of camelina (Camelina sativa (L.) Crantz), a trial was carried out over a two-year period. This study analysed two different levels of input: a low input treatment (shallow non-inversion tillage and low fertilisation rate) and a high input treatment (deeper tillage and high fertilisation rate). Camelina was positively, even though to a limited extent, affected by high input treatment as highlighted by the increase in seed yield (from 1.8 to 2.0 t ha^–1), crop residues (from 4.8 to 5.2 t ha^–1), seed protein content (from 26.5 to 28.9%), seed oil content (from 41.5 to 43.4%) and oil yield (from 0.75 to 0.88 t ha^–1). So, from a sustainable point of view, we must consider negligible the effect of high input and satisfactory the performances of camelina in the low input regime. Low input management resulted in satisfactory yields in terms of both quantity and quality, results which were not very different from high input, indicating promising potential for conservation agriculture practices in camelina in a semi-arid environment.

Highlights
- Camelina showed high adaptability to conservation agriculture practices.
- Seed yield of 1.9 t ha^–1 was obtained under reduced tillage and low fertilisation rate.
- High inputs (fertilisation and tillage) determined a 12-d longer crop cycle.
- α-linolenic, erucic and eicosenoic acids were affected by input levels.

由于需要大量投入，人们常被指责种植用于生物燃料生产的油料作物在环境上是不可持续的。为了研究减少的投入量对山茶（Camelina sativa（L.）Crantz）的生产性和定性性状的影响，进行了为期两年的试验。这项研究分析了两种不同的投入水平：低投入处理（浅层非反转耕作和低施肥率）和高投入处理（深耕和高施肥率）。尽管产量有限，但骆驼茶还是受到高投入处理的积极影响，如种子产量（从1.8到2.0 t ha ^–1），农作物残渣（从4.8到5.2 t ha ^–1）的增加所突出），种子蛋白质含量（从26.5至28.9％），种子油含量（从41.5至43.4％）和油脂产量（从0.75至0.88 t ha ^–1）。因此，从可持续的角度来看，我们必须考虑高投入的效果可以忽略不计，而在低投入条件下令人满意的山茶花性能则要忽略不计。低投入管理在数量和质量上均取得令人满意的产量，其结果与高投入并没有很大的不同，这表明在半干旱环境下在茶花上进行保护性农业实践的潜力很大。

亮点
-Camelina对保护性农业实践表现出高度的适应性。
-在少耕和低施肥的情况下，获得了1.9 t ha ^–1的种子产量。
-高投入（施肥和耕作）决定了12天的作物周期更长。
-α-亚麻酸，芥酸和二十碳烯酸受输入水平的影响。
