Résumé partiel
The subject-matter of the research is the impact of agro-ecological and soil conditions of Podunavlje and Posavina on morphological and productive properties of Khorasan wheat (a population of the white awn). The investigations were conducted during the course of two years (2015 and 2016). The field trials were carried out in a randomised block design on two soil types (chernozem and wetland black soil) during two meteorologically different years. Having increased the amounts of NPK mineral fertilisers used in side-dressing, variations in the morphological and productive properties, namely kernel yield components, were studied. Laboratory analyses of the agro-chemical and physical properties of the soil were conducted prior to setting up the experiment, and in the period from sowing to harvest, meteorological data with the highest impact on the growth and development of this plant species were studied. The indicators of the morphological properties were measured directly on the samples, whereas the indicators of the productivity and the harvest index were measured after drying of the main product and by-products. At the laboratory of pharmacognosy, the amounts of starch, total protein, cellulose, total lipid, mineral salt and water in dry matter were measured and NFE was calculated. The obtained results show that Khorasan wheat can be introduced successfully into agricultural areas in Podunavlje and Posavina, although the investigated treatments, both uncontrolled (agro-ecological and soil conditions) and the controlled ones (NPK fertilisers) exhibited statistically significant variations in the morphological and productive properties of this small grain. On the whole, the morphological and productive properties as well as yield components were mostly affected by side-dressing, which shows a good genetic potential of the wheat population in question as a cultivar suitable for cultivation, but also for further breeding. Its interaction with soil and weather conditions shows good productive properties of Khorasan wheat, a cultivar that should be introduced into regular commercial production in Serbia
