Abstract

In the 18th year of a long-term fertilisation experiment set up on calcareous loamy chernozem soil, tests were made on the effects of various N, P and K supply levels and their combinations on the nutrient content and nutrient uptake of the grain and straw of triticale at harvest, and on the composition of the shoots at the tillering stage, which was used as an indication of nutritional status. The soil of the experimental location contained 3% humus, 5% CaCO3 and 20% clay in the ploughed layer, and was supplied moderately well with N and K and poorly with P and Zn. The experiment consisted of 4N×4P×4K = 64 treatments in two replications, giving a total of 128 plots. The fertilisers were applied in the form of calcium ammonium nitrate, superphosphate and 50% potassium chloride. The groundwater was at a depth of 15 m and the area had a tendency to drought. The main results can be summarised as follows: 1. N fertilisation led to an increase in the incorporation of the macroelements N, K Ca and S and the microelements Na, Mn, Zsn, Sr and Mo into the plant organs. The NO3-N concentration of the nutrient reserves in the straw at harvest rose 20-fuld as the result of excessive rates of N. 2. In most plant organs P fertilisation caused an increase in the accumulation not only of P, but also of N, NO3-N, Ca, Mg, Na, Mn, Sr and Cd, while there was a pronounced drop in the Zn content due to P-Zn antagonism. The high (1-2%) Sr contamination in the superphosphate applied contributed to a doubling of plant Sr uptake. 3. K fertilisation resulted in an increase in the K content and a decline in the accumulation of Ca, Mg and Sr, due to cation antagonism. There was also a slight reduction in S incorporation. 4. The maximum yield of 7 t grain + 12 t straw and husks, i.e. 19 t/ha aboveground biomass, removed 295 kg N, 183 kg K, 56 kg Ca, 31 kg P, and 20 kg each of Mg and S from the soil. The specific element contents calculated for 1 t grain and the corresponding by-products ranged from 29-42 kg N, 13-26 kg K (16-31 kg K2O), 4-8 kg Ca (5-11 kg CaO), 3.6-4.4 kg P (8-10 kg P2O5), 1.8-2.6 kg Mg (3-4 kg MgO) and 2-3 kg S, depending on the fertiliser treatment. 5. The following values were recorded for the specific microelement content on the given soil, as a function of the treatments: 100-360 g Na, 140-200 g Mn, 100-140 g Fe, 25-38 g Ba, 21-38 g Al, 9-33 g Sr, 21-23 g Zn, 12-14 g B, 7-10 g Cu, and 0.2-0.4 g Ni and Mo. 6. A shoot composition of 4-5% N, 0.3-0.5% P and 2-4% K at the end of tillering can be used as a guideline for the optimum nutritional status of triticale, while ratios of 8-15 for N/P, 6-10 for K/P and 1.5-2.5 for N/K arc indicative of balanced nutrient supplies.
