BIELSKI, St. and B. SZWEJKOWSKA, 2015. Influence of some agro-technical treatments on the development and yields of amaranth. Bulg. J. Agric. Sci., 21: 909–915
This study was based on a field experiment conducted in 2010-2012 at the Experimental Station in Tomaszkowo near Olsztyn. The experiment was set up on light soil of very good rye complex, in a split-plot sub-block design with four replications. During the experiment, amaranth seeds were sown at a rate of 1.5 kg ha-1, in rows spaced at 50 cm, in the last decade of May. The objective was to determine the effect of different doses of mineral fertilization (N + P + K) and fungicide treatments on the yield of seeds, protein and fat per field area unit and on some biometric traits: plants’ height, length of inflorescences, 1000-seed weight, obtained from the amaranth cultivar Aztek. It was determined that mineral fertilization had a significant influence on all analyzed characteristics. The highest parameters of the tested traits were achieved from the plots with the highest mineral fertilization. The level of fungal control had a significant effect only on the protein yield.
