Abstract. The aim of the study was to investigate the productivity and yield stability at durum wheat (Triticum durum Desf.) treated with antibroadleaved herbicides during 3-rd stem node stage. The experiment was conducted during 2012-2014 on pellic vertisol soil type. Under investigation was Bulgarian durum wheat cultivar Victoria (Triticum durum var. valenciae). A total of 20 antibroadleaved herbicides were tested: Granstar 75 DF, Granstar super 50 SG, Ally max SG, Arat, Biathlon 4 D, Derby super WG, Mustang 306.25 SC, Weedmaster 646 CL, Sunsac, Secator OD, Logran 60 WG, Lintur 70 WG, Akurat 60 WG, Akurat extra WG, Eagle 75 DF, Herbaflex, Starane 250 EK, Sanafen, Dicotex 400 and Herby 675. All herbicides were treated in 3-rd stem node stage of durum wheat. It was found that during 3-rd stem node stage of durum wheat the antibroadleaved herbicides Arat, Biathlon, Derby super, Secator, Lintur, Akurat, Akurat extra and Starane can be used. These herbicides do not have a negative influence on grain yield. The most unstable yield is obtained after the treatment with herbicides Granstar, Granstar super, Ally max, Sunsac, Logran, Eagle, Herbaflex and Herby. Their selectivity to durum wheat is influenced most strongly by weather conditions during the vegetation period. From the viewpoint of technology for durum wheat growing, during 3-rd stem node stage technologically the most valuable are herbicides Derby super, Arat, Biathlon, Secator, Akurat, Akurat extra and Lintur. After the treatment with them high grain yield with high stability with relation to different years is obtained. The herbicides Granstar, Granstar super, Ally max, Sunsac, Weedmaster, Logran, Eagle, Herbaflex, Sanafen, Dicotex and Herby cannot be used during 3-rd stem node stage of durum wheat.

Abstract. The research was conducted during 2012-2014 on pellic vertisol soil type. Investigated was the Bulgarian durum wheat cultivar Victoria (Triticum durum var. valenciae). A total of 20 antibroadleaved herbicides were investigated: Granstar 75 DF, Granstar super 50 SG, Ally max SG, Arat, Biathlon 4 D, Derby super WG, Mustang 306.25 SC, Weedmaster 646 CL, Sunsac, Secator OD, Logran 60 WG, Lintur 70 WG, Akurat 60 WG, Akurat extra WG, Eagle 75 DF, Herbaflex, Starane 250 EK, Sanafen, Dicotex 400 and Herby 675. All herbicides were treated in 2-nd stem node stage of durum wheat. During 2-nd stem node stage of durum wheat the following antibroadleaved herbicides can be used: Arat, Biathlon, Derby super, Mustang, Secator, Lintur, Akurat, Akurat extra, Starane, Dicotex and Herby. These herbicides do not have a negative influence on grain yield. The most unstable treatments are with herbicides Granstar, Granstar super, Ally max, Sunsac, Logran, Eagle, Herbaflex and Herby. Their selectivity to durum wheat is influenced most strongly by weather conditions during the vegetation period. From the viewpoint of technology for durum wheat growing, during 2-nd stem node stage technologically the most valuable are the herbicides Derby super, Arat, Biathlon, Secator, Akurat, Akurat extra and Lintur. Their application provides high and stable grain yield during different years. The herbicides Granstar, Granstar super, Ally max, Sunsac, Weedmaster, Logran, Eagle and Herbaflex cannot be used during 2-nd stem node stage of durum wheat.

<p class="4Body">Total Dray Matter (TDM), Photosynthetically Active Radiation Intercepted (PARabs), Water Consumption (WC), Water use- (WUE), Radiation use efficiency (RUE) and the Relation between Radiation Interception and Water Consumption for Durum Wheat were investigate under different irrigation amount (D<sub>1</sub>= 100 % ETc; D<sub>2</sub>= 70 % ETc; D<sub>3</sub>= 40 % ETc and D<sub>4</sub>= pluvial) and during three growing seasons (2005-2006, 2006-2007 and 2007-2008). Results showed that, the cumulative PARabs decreased with deficit irrigation. In fact, D<sub>1</sub> treatment recorded the highest cumulative PAR abs and the lowest marked under D<sub>4</sub> treatment. Similarly, TDM and RUE were decreased with deficit irrigation. The highest RUE observed under the D<sub>1</sub> (from 1.32 to 1.43 g MJ<sup>-1</sup>) and the lowest under D<sub>4</sub> (from 1.17 to 1.29 g MJ<sup>-1</sup>). However WUE increased with deficit irrigation. The highest WUE were obtained under the D<sub>4</sub> (from 3 to 4 kg m<sup>-3</sup>) and the lowest were observed under D<sub>1</sub> (from 2.8 to 3.1 kg m<sup>-3</sup>). Significant linear relationship was found between cumulative PAR abs and cumulative water consumption with a high correlation coefficient (R<sup>2</sup>) only under the two treatments D<sub>1</sub> and D<sub>2</sub>.</p>

Investigations were carried out in 2007-2009 on the plots of the Felin Experimental Station belonging to the University of Life Science in Lublin. The studies comprised two cultivation lines of durum wheat (<i>Triticum durum</i> L.): STH 716 and STH 717, as well as the 'Tonacja' cultivar of common wheat (<i>T. aestivum</i> ssp. <i>vulgare</i> L.). Two levels of chemical protection were applied in the cultivation: minimal and complex protection. Infection of wheat roots and stem bases was recorded in each growing season at hard dough stage (87 in Tottman's scale, 1987). After three years of study, the mean disease indexes for the analyzed wheat genotypes in the experimental treatment with minimal protection were 31.13, 30.43 and 38.83 for, respectively, the 'Tonacja' cultivar and the cultivation lines of <i>T. durum</i> STH 716 and STH 717. In the experimental combination with complex protection, after three years of study the disease indexes ranged from 25.26 (<i>T. durum</i> STH 716) to 30.83 (<i>T. durum</i> STH 717). The results of mycological analysis of diseased plants showed that <i>Fusarium</i> spp., especially <i>F. culmorum</i>, <i>F. avenaceum</i> as well as <i>Bipolaris sorokiniana</i> and <i>Rhizoctonia solani</i>, caused root rot and necrosis of wheat stem bases. The analyzed chemical protection levels did not significantly influence grain yield of the investigated genotypes of <i>T. aestivum</i> and <i>T. durum</i>.
