Abstract

Interactions were studied between the elements K, B and Sr in poppy in 1998, in the 11th year of an experiment set up on pseudomyceliar (calcareous) chernozem soil at the Experimental Station of the Institute in Nagyhörcsök.Basic fertilization generally consisted of 100 kg each of N and P2O5 per hectare per year, given in the form of 25% calcium ammonium nitrate and superphospate. The K levels were adjusted using repeated doses of 0, 1000 and 2000 kg K2O, the B levels with repeated doses of 0, 20, 40 and 60 kg B and the Sr levels with 0 and 67 kg Sr per hectare, applied in the form of 60% KCl, 11% borax and 33% SrCl2·6H2O. The main plots were the 3 K treatments, the subplots the 4 B treatments and the sub-subplots the 2 Sr treatments, giving a total of 24 treatments × 3 replications = 72 plots in a split-plot design.When the experiment was set up in autumn 1987 the ploughed layer contained 5% CaCO3, 3% humus and 20% clay. The pH (H2O) value was 7.8 and the pH (KCl) 7.3. The AL-soluble K 2O and P2O5 values were 180-200 and 100-200, the KCl-soluble Mg 110-150, the KCl+EDTA-soluble Mn 60-80, the Cu and Zn 1-2 and the B 0.7 mg·kg-1. The soil nutrient supplies were satisfactory for K, Ca and Mg, moderate for N and P and poor for Zn and Cu. The groundwater was at a depth of 13-15 m and the area was prone to drought. The mean temperature averaged 11 C and the annual rainfall sum was 400-600 mm, with uneven distribution.The poppy variety Kompolti M was sown at a depth of 1-2 cm on 16 March 1998 with a row distance of 45 cm. The agronomic measures and methodological observations are presented in Table 1.The main conclusions were as follows: -1, consisting of 3.4 t·ha-1 stems, 1.1 t·ha-1 capsules and 1.6 t·ha-1 seed.-The boron fertilizer was not leached into the deeper soil layers even after six years. The B content in the plant organs of poppy, which has a shallow root system, increased many times at greater B rates, with a simultaneous drop in the Ca and Mg concentrations of the stems and capsules. K fertilization enhanced the K% of the stems and capsules and reduced that of Mg. There was also a significant increase in the Sr content of the poppy organs after six years in response to the application of 67 kg Sr·ha-1.-The specific/unit element content of 1 t seed and the corresponding by-products amounted to 79-41-114-109-20 kg·t-1 N-P2O 5-K2O-CaO-MgO, respectively. Similar specific values were recorded in earlier experiments, and are on average approximately twice the specific N, P and K values recommended by the Hungarian extension service and 5-6 times those given for Ca and Mg. It is thus suggested that the recommended values should be revised.li.
