The addition of zinc at 20 mg kg−1 to soils in a growth chamber study reduced the shoot Cd concentration of two durum wheat (Triticum turgidum L. var durum) lines at 10 °C, 16 °C, and 22 °C soil temperatures while additions of ammonium nitrate (NH4NO3) and monoammonium phosphate (NH4H2PO4) increased shoot Cd concentrations. Applying Zn with NH4NO3 or NH4H2PO4 reduced shoot Cd concentrations of the plants to levels comparable to the control. Key words: Cd, durum wheat, ammonium nitrate, monoammonium phosphate, Zn

The first durum wheat [Triticum turgidum L. ssp. durum (Desf.) Husn.] cultivar developed in Canada was Stewart 63, registered in 1963. The objective of this paper is to document genetic progress in Canadian durum cultivars since that time. The genetic potential for grain yield in the main durum production area increased by about 0.7% per year and shows no sign of tapering off. This genetic potential has been captured in commercial farm yields, which increased by 1.5% per year during the same period. Grain protein concentration tended to increase slightly over the same time period because of the requirement for minimum protein concentration for cultivar release in Canada. Based on a study of two unselected doubled haploid populations, it was estimated that genetic gain for grain yield was reduced by 8 to 15% because of the negative correlation of protein concentration with yield. Yellow pigment concentration of semolina increased during the study period, especially after the mid 1990s, when higher pigment became an important breeding target. Gluten strength has also been increased since the mid 1990s. Grain cadmium concentration was reduced by about 50% to satisfy the requirements of certain export markets. Resistance to leaf and stem rust was maintained in all cultivars released since Stewart 63. In the past 10 yr, breeding has exploited genetic variation in resistance to Fusarium head blight to produce cultivars such as Brigade and CDC Verona with intermediate levels of resistance. There appears to be remaining genetic variability for all major traits in lines currently in registration trials.

AAC Stronghold durum wheat [Triticum turgidum L. subsp. durum (Desf.) Husn.] is adapted to the durum production area of the Canadian prairies. Averaged over 3 yr, AAC Stronghold yielded significantly more grain than AC Navigator. AAC Stronghold had a protein concentration significantly less than Strongfield but significantly more than Brigade. AAC Stronghold had a plant height significantly shorter than Brigade, Strongfield, and AAC Cabri, with a lodging score significantly less than Strongfield and AAC Cabri. AAC Stronghold has a solid stem, which confers resistance to cutting by the wheat stem sawfly (Cephus cinctus Norton). AAC Stronghold had low grain cadmium concentration and stronger gluten than Strongfield. AAC Stronghold is eligible for grades of Canada Western Amber Durum.

The objective of this study was to assess the energy efficiency of nitrogen fertilization in durum wheat and sorghum grains in the period 2017-2019. Bulgarian durum wheat variety Predel was studied at a stationary fertilizer trial on soil type Pellic vertisols at the Institute of Field Crops in Chirpan, Bulgaria. Grain sorghum hybrid EC Alize was investigated on the experimental field of the Agricultural University of Plovdiv, Bulgaria, on soil type Mollic Fluvisols. The crops were grown under non-irrigated conditions. The studied nitrogen rates were 0, 60, 120, 180, and 240 kg N.ha-1. In durum wheat, nitrogen was applied two times: one third at sowing, and the rest - as top dressing in the tillering stage.  In sorghum, the total nitrogen was applied as pre-sowing fertilization before sowing. The nitrogen fertilizer was applied as NH4NO3. The experimental design was a randomized, complete block design with four replications with a size of experimental plots of 20 m2 for both crops. The energy efficiency of nitrogen fertilization (h) was calculated as the ratio between the received energy from additional grain yield of wheat and sorghum, respectively, and the invested energy from fertilization. It was established that energy efficiency of nitrogen fertilization depended on the nitrogen rate and hydro-thermal conditions during the vegetation period of durum wheat and sorghum. The bioenergy coefficient of durum wheat widely varied from 0.79 (N240 in 2018) to 4.44 (N60 in 2017). The average for the period, the highest value of energy efficiency of nitrogen fertilization was obtained at the low rate N60 The higher nitrogen rate of 240 kg N.ha-1 was slightly effective. Under drought conditions during the vegetation period of sorghum, most effective was the application of rates N120 with the highest energy coefficient ​​of 1.23. The application of 180 kg N.ha-1 to sorghum was the most energy efficient under the favorable hydro-thermal conditions in 2018 and 2019, and the average for the period 2017-2019. A low N60 rate in grain sorghum was inefficient from an energy point of view. Durum wheat showed higher energy efficiency of nitrogen fertilization compared to grain sorghum.

Cadmium concentration in durum (Triticum turgidum) grain may be influenced by fertilizer management. A 3-yr field study conducted on two Orthic Black Chernozemic soils investigated the effects of banded and broadcast applications of N and P, and applications of Zn fertilizer on the yield and Cd concentration of the grain of two cultivars of durum wheat. Applications of N and P fertilizer increased grain yield of durum wheat when soil nutrient supply was low or yield potential was high, while Zn application generally had little effect on grain yield. Cadmium concentration of durum increased with applications of N and P and was generally unaffected by Zn application. Method of application of N or P did not consistently influence either grain yield or Cd concentration of the grain under the conditions of this study. Where differences due to placement occurred, banded P produced higher grain yield and Cd concentration than application of the same level of P as a broadcast treatment. Cadmium accumulation increased substantially with N and P applications, since both Cd concentration in the grain and grain yield increased with N and P application. Year-to-year variation in Cd concentration in the grain was large, indicating a strong effect of environment on Cd phytoavailability. Key words: Management, banding, nutrient, accumulation
