“…However, at an irrigation quota of 2 400 m 3 ha -1 , flax yield decreased by 2.3%. Thus, flax yield increased up to an inflection point with increasing irrigation quotas, which is consistent with the findings of Rebetzke et al (2016) and Yang et al (2022). The observed trend of flaxseed yield in response to irrigation quota was consistent with that of flax yield.…”

laxseed (Linum usitatissimum L.) oil is an important crop in China, which is rich in saturated fatty acids, alpha-linolenic acid, and other essential nutrients for the human body. Here, we investigated the effects of different irrigation and fertilization conditions on flax yield and quality in semi-arid regions in northern China. Using non-weighing lysimeter fertilization versus non-fertilization, the effects of four irrigation treatments (1 500, 1 800, 2 100, and 2 400 m3 ha-1) on flax yield and quality were assessed for the flax cultivar ‘Yajin7.’ As the irrigation quota increased, both the aboveground fresh weight and flaxseed biomass initially increased and subsequently decreased. The flax fresh weight and seed weight increased by 74.52 and 80.70%, at irrigation quotas of 2 100 and 1 500 m3 ha-1, respectively; however, irrigation quota had no significant effect on flax quality. Fertilizer application significantly improved flax and flaxseed yields by 127 and 77%, respectively, increased mean flax protein content from 20.05 to 24.63%, and decreased the mean lipid content from 46.52 to 43.67%. However, fertilization had no effect on the content of palmitic, stearic, oleic, linoleic, and linolenic acids. Overall, our results highlight that water related benefits to flax crops decrease in response to increasing the irrigation quota and appropriate fertilizer application can significantly improve flax yield and quality. Therefore, this study provides a theoretical basis for irrigation and fertilization related to flax cultivation in northern China

“…This equivalence underscores their pivotal role in shaping agricultural productivity. Moreover, these discoveries align harmoniously with prior research conducted at experimental sites [30][31][32][33][34][35][36] , thereby providing additional validation to the paramount importance of these best management practices in advancing the cause of sustainable agriculture.…”

Enhanced agricultural management practices hold the potential to drive agricultural sustainability 1, 2 , a facet that is rarely quanti ed at the grassroots level. In this study, we conduct an analysis of nitrogen use and loss in Chinese cropland, drawing from data collected from 2,238,550 sites in two national agricultural pollution source censuses spanning from 2007 to 2017. Our ndings reveal a signi cant upswing of 10% in crop yields and an impressive 8% reduction in nitrogen pollution during this period. This positive shift can be attributed to the promotion and adoption of various agricultural management practices in China, including the combination of organic and chemical fertilizers, no-tillage farming, straw recycling, and deep-placement of fertilizer. These practices have collectively contributed to an 18% increase in nitrogen use e ciency within the country. Moreover, by fully embracing these advanced practices, we project that annual cropland pollution could experience a further reduction of up to 1.7 million tonnes of nitrogen without compromising crop yield. Importantly, the bene ts of these measures, encompassing both environmental and human health advantages, are expected to consistently outweigh the implementation costs in the future, with total bene ts reaching as high as US$15 billion.
