Abstract
The research was conducted during 2010 - 2012 on pellic vertisol soil type. Under investigation was Bulgarian durum wheat cultivar Predel, which belongs to var. valenciae. Factor A included no treated check and 3 foliar fertilizers - Lactofol O - 8 l/ha, Terra-sorb - 3 l/ha, Humustim - 1 l/ha. Factor B included weeded, no treated check and 3 combined herbicides – Axial one (pinoxaden + florasulam) - 1 l/ha, Hussar max OD (mesosulfuron + iodosulfuron) – 1 l/ha, Palace 75 WG (pyroxulam) - 250 g/ha. Because of the low adhesion of the herbicide Palace it was used in addition with adjuvant Dassoil - 500 ml/ha. All of foliar fertilizers, herbicides and their tank-mixtures were treated in tillering stage of the durum wheat and are applied in a working solution of 200 l/ha. Mixing was done in the tank on the sprayer. Tank mixtures of combined herbicide Axial one with complex foliar fertilizers Lactofol and Terra-sorb decreases germination energy of the durum wheat seeds. Tank mixture Lactofol + Hussar max decreases lab seed germination. Investigated foliar fertilizers, combined herbicides and their tank mixtures increase lengths of primary roots and coleoptile and decrease waste grain quantity. Combination between herbicide Hussar max and foliar fertilizer Lactofol not influences on lengths of primary roots and coleoptile. There is antagonism of combined use by herbicide Hussar max with foliar fertilizers Lactofol and Humustim and by herbicide Palace with foliar fertilizer Lactofol. There is synergism by tank mixtures of herbicide Axial one with the three foliar fertilizers, by tank mixtures of herbicide Palace with foliar fertilizers Lactofol and Humustim, by tank mixtures of herbicide Hussar max with foliar fertilizer Terra-sorb. The highest grain yield is obtained by tank mixture Terra-sorb + Axial one.
