Abstract

New barley products can be developed by modifying the content of bioactive components in the grain through breeding, as well as improving its quality at lower fertilizer costs. We aimed to study the effects of the genotype, growth conditions, and top-dressing application of nitrogen and organo-mineral fertilizers on the chemical composition of barley grain. The barley varieties Novichok, Rodnik Prikamya, and Pamyaty Rodinoy were grown under normal (2020) and dry (2021) field conditions. The plants were top-dressed with mineral (CAS; SpetsKhimAgro, Kirovo-Chepetsk, Russia) or organo-mineral (Amino Start and Alfastim; Polydon® Agro, Moscow, Russia) fertilizers in the tillering or heading phases. The contents of protein, starch, fat, and crude fiber in the grain were analyzed with an INFRAMATIC 8620 instrument (Perten Instruments, Stockholm, Sweden). The CAS fertilizer reduced protein, fat, and fiber by 4.5–8.3% (Novichok) during the drought and increased starch by 2.1% (Novichok), fiber by 14.2% (Rodnik Prikamya), and fat by 18.9% (Pamyaty Rodinoy) under normal humidity. Amino Start applied under normal conditions increased starch by 2.9% and reduced protein and fat by 7.8–8.9% in Rodnik Prikamya, as well as increased protein and fat by 14.4 and 6.3%, respectively, but reduced starch by 5.1% in Pamyaty Rodinoy. Alfastim applied under normal conditions reduced the content of protein by 10.7% (Rodnik Prikamya), but increased it by 3.6–7.2% in the other cultivars. It also increased fiber by 22.8% in Rodnik Prikamya, but decreased it by 18.6% in Pamyaty Rodinoy. Finally, this fertilizer decreased fat by 12.7% in Rodnik Prikamya, but increased it by 9.8% in Pamyaty Rodinoy. In the drought, the fertilizers Alfastim and Amino Start increased the protein content by 5.2–12.2% in Rodnik Prikamya and Pamyaty Rodinoy. Top-dressing barley plants with mineral or organo-mineral fertilizers can modify the grain composition (up to 10.4% of fiber, 3.6% of starch, and 7.5% of protein and fat), depending on the consumer’s requirements.

春大麦追肥处理对其品质的影响

新的大麦产品可以通过育种改变谷物中生物活性成分的含量，以及以较低的肥料成本提高其质量来开发。我们旨在研究基因型、生长条件以及氮和有机矿物肥料的追肥施用对大麦籽粒化学成分的影响。大麦品种Novichok、Rodnik Prikamya和Pamyaty Rodinoy是在正常（2020）和干燥（2021）的田间条件下种植的。这些植物在分蘖期或孕穗期使用矿物肥料（CAS；SpetsKhimAgro，Kirovo-Chepetsk，俄罗斯）或有机矿物肥料（Amino Start和Alfstim；Polydon®Agro，莫斯科，俄罗斯）进行了顶级处理。使用INFRAMATIC 8620仪器（Perten Instruments，Stockholm，Sweden）分析谷物中蛋白质、淀粉、脂肪和粗纤维的含量。CAS肥料在干旱期间减少了4.5-8.3%的蛋白质、脂肪和纤维（Novichok），在正常湿度下增加了2.1%的淀粉（Novichock）、14.2%的纤维（Rodnik Prikamya）和18.9%的脂肪（Pamyaty Rodinoy）。在正常条件下施用氨基起始物可使Rodnik Prikamya的淀粉增加2.9%，蛋白质和脂肪减少7.8-8.9%，蛋白质和油脂分别增加14.4%和6.3%，但Pamyaty Rodinoy的淀粉减少5.1%。在正常条件下施用Alfstim使蛋白质含量降低了10.7%（Rodnik Prikamya），但在其他品种中增加了3.6-7.2%。它还使罗德尼克·普里坎亚的纤维增加了22.8%，但使帕米亚蒂·罗迪尼的纤维减少了18.6%。最后，这种肥料使罗德尼克·普里坎亚的脂肪减少了12.7%，但使帕米亚蒂·罗迪尼的脂肪增加了9.8%。在干旱中，化肥Alfstim和Amino Start使Rodnik Prikamya和Pamyaty Rodinoy的蛋白质含量增加了5.2-12.2%。根据消费者的要求，用矿物或有机矿物肥料对大麦植株进行追肥可以改变谷物成分（纤维含量高达10.4%，淀粉含量高达3.6%，蛋白质和脂肪含量高达7.5%）。

期刊介绍： The journal «Foods and Raw Materials» is published from 2013. It is published in the English and German languages with periodicity of two volumes a year. The main concern of the journal «Foods and Raw Materials» is informing the scientific community on the works by the researchers from Russia and the CIS, strengthening the world position of the science they represent, showing the results of perspective scientific researches in the food industry and related branches. The main tasks of the Journal consist the publication of scientific research results and theoretical and experimental studies, carried out in the Russian and foreign organizations, as well as on the authors'' personal initiative; bringing together different categories of researchers, university and scientific intelligentsia; to create and maintain a common space of scientific communication, bridging the gap between the publications of regional, federal and international level.
