TECHNICAL CROPS
TECHNICAL CROPS, the cultivated plants used as raw materials for various industries. T.c. include oil crops, sugar (sugar beet, etc), amyliferous (potatoes, etc), essential oil (mint, muscat sage, etc.), textile (hemp, flax, etc), dyeing (black mallow, henna, etc), tanning (oak, pine, larch, etc), rubber-bearing (silkweed, koksagyz, tau-sagyz, etc), gutta-percha-bearing (wartybark euonymus, eucommia, etc), cork-bearing (cork oak), medicinal plants, etc. Some T.c. have a double use: flax, hemp and cotton are used for fiber and fatty oil production; coriander, carraway and anise — for fatty and essential oil production, etc. T.c. are annual and perennial plants, growing in various natural zones. The sunflower, sugar beet, potato and spring rapeseed are cultivated large-scale in the RB. The most favorable conditions for the cultivation of potatoes and rapeseed are in the N., N.-E. and S. forest- steppe zones; sunflower, beet and soy — in the S. forest-steppe and pre-Ural steppe zones.
