Formation of yield and quality of topinambur tubers with different planting techniques

   To expand the production of topimanbur in the Russian Federation, it is necessary to develop adaptive cultivation technologies in various regions of the country. Field research was carried out on the territory of the educational and scientific experimental field of the Perm State Technical University. Three variants of the planting scheme were studied: 70x30, 70x40 and 70x50 cm and three variants of the weight of the planting tuber: 20-40 g, 41-60 g and 61-80 g. The applied agrotechnical measures are generally accepted for the non–Chernozem zone. The technology of planting topinambur is a comb. The research results show that with planting schemes of 70x30, 70x40 and 70x50 cm, topinambur forms the exact yield of tubers – 18.3-19.3 t/ha. When used for planting tubers weighing 41-80 g, the yield increases by 1.1-1.7 t/ha, compared with the planting fraction of 21-40 g, due to an increase in plant density by 0.1 pcs. /m². Biological yield indicators fully reflect the actual yield. Under the studied planting schemes, it was also the same and amounted to 2002.6-2177.9 g/m², and when planted with larger tubers, it was 271.7-277.0 g/m² higher than tubers of 20-40 g. The proportion of tubers of the small fraction – 48-59 % prevails in the Jerusalem artichoke crop. The share of the food fraction is 8-16 %. The fractional composition of tubers in the crop does not depend on the mass of the planting tuber. The share of planting tubers in the harvest with schemes 70x30 and 70x40 cm is higher by 6-8 %. A higher dry matter content in tubers was observed when planting tubers weighing 20-60 g – 21.3-21.6 %, and vitamin C – when planting tubers 61-80 g – 14.5 mg/kg. The planting scheme does not affect the biochemical composition of topinambur tubers.
