ABSTRACT

Most faba bean research is about protein content while less attention is paid to nutrient content. Thus, the purpose of this study was to assess the effect of sowing rate and variety on the nutrient content of faba beans. Five varieties were tested: Bauska, Gloria, Julia, Jõgeva, and Lielplatones. Two sowing rates were used: 30 seeds m⁻² (100%) and 36 seeds m⁻² (120%). The higher sowing rate decreased the K content in varieties Gloria, Julia, and Lielplatones in 2016. In 2015 the higher sowing rate increased the Ca content while in 2016 the sowing rate decreased the Ca content. The higher sowing rate increased the Mg content in varieties Gloria and Jõgeva in 2016. The highest N, K, and Mg contents were found in variety Gloria. In 2015 the highest K content was found in varieties Gloria and Jõgeva, while in 2016 the highest K content was in variety Lielplatones. The highest Ca content was in variety Bauska. In conclusion, an increased sowing rate did not have a consistent effect on the nutrient content of faba beans. Thus, variety Gloria can be recommended for faba bean production in Northern Europe because it was the variety with the highest nutrient content.

摘要

大多数蚕豆研究是关于蛋白质含量的，而对营养成分的关注较少。因此，本研究的目的是评估播种率和品种对蚕豆营养成分的影响。测试了五个品种：Bauska、Gloria、Julia、Jõgeva 和 Lielplatones。使用了两种播种率：30 粒种子 m ^-2 (100%) 和 36 粒种子 m ^-2(120%)。2016 年高播率降低了 Gloria、Julia 和 Lielplatones 品种的钾含量。2015 年高播率提高了钙含量，而 2016 年播率降低了钙含量。2016 年，较高的播种率提高了品种 Gloria 和 Jõgeva 的镁含量。品种 Gloria 中发现的 N、K 和 Mg 含量最高。2015 年发现的钾含量最高的是品种 Gloria 和 Jõgeva，而 2016 年的钾含量最高的是品种 Lielplatones。Ca 含量最高的是 Bauska 品种。总之，增加播种率对蚕豆的营养含量没有一致的影响。因此，可以推荐品种 Gloria 用于北欧的蚕豆生产，因为它是营养含量最高的品种。
