Yield of winter cultivars of spelt wheat (Triticum aestivum ssp. spelta L.) cultivated under diversified conditions of mineral fertilization and chemical protection

摘要: The field experiment was carried out in years 2008-2010 on rendzina soil. aim of the research to determine effect chemical protection level yield two winter spelt cultivars – Schwabenkorn and Spelt I.N.Z. cultivated under different conditions mineral fertilization. Chemical levels included: A) control, B) Mustang 306 SE, Stabilan 750 SL, C) Attribut 70 WG, D) Alert 375 SC, SL. Mineral fertilization as follows (in kg pure component per hectare): lower N 60, P 26.2, K 83, higher 80, 34.9, 99.6. Significantly grain yields were obtained from cultivar compared with cv. Application rates fertilizers significantly increased number ears 1 m well wheat but had no weight 1000 grains, grains ear. caused yield, 29.8 33.7%, control without protection.
