Abstract

The effect of rainfall quantity and N, P, K, Mg fertilisation on the yield of winter wheat was evaluated in the 7th year of a long-term mineral fertilisation experiment set up on sandy acidic Icssivatcd brown forest soil in Nyirlugos. The agrochemical parameters of the soil were as follows: pH (H 2O) 5.9, pH (KCl) 4.7, hydrolytic acidity 8.4, hy1 0.3, humus 0.7%, total N 34 mg kg-1, AL-P2O5 43 mg kg-1, AL-K2O 60 mg kg-1. From 1962 to 1980 the experiment consisted of 2×16×4×4=512 plots and from 1980 of 32×4=128 plots in split-split-plot and factorial random block designs. The gross plot size was 10×5 = 50 m2. The average fertiliser rates in kg · ha-1 · year-1 were nitrogen 45, phosphorus 24 (P2O5), potassium 40 (K2O), magnesium 7.5 (MgO) until 1980 and nitrogen 75, phosphorus 90 (P 2O5), potassium 90 (K2O), magnesium 140 (MgCO3) after 1980. The main results and conclusions were as follows: 1. On the basis of "general" (Harnos, 1993) and winter wheat-specific rainfall deficiency values the years could be classified as average (1978, 1982, 1989), dry (1974), droughty (1976, 1990) and wet (1980). 2. In average years the yield of the control plots became stabilised at the 1.6 t ha -1 level. In the fertilised treatments the highest yield (3.71 ha-1) was more than one and a half times the lowest yield (2.3 t ha-1). N, NP and NK fertilisation resulted in an increase of around 1.01 ha-1 in the main yield compared with the control. The wheat yields could only be enhanced economically by full treatment with NPK or NPKMg. 3. Without fertilisation the yield in the dry year (1.7 t · ha -1) was similar to that in the average year (1.6 t · ha -1). The extent of loss was 12% in the N, NP and NK treatments and 10% in the NPK and NPKMg treatments. 4. In the case of drought the grain yield of the control plots was approx. 30% lower than in the average year. The loss in the one-sided N and deficient NP and NK combinations was 41%, and this was aggravated by a further 7% by the NPK and NPKMg rates (48%). 5. In the wet year the yield declined even more than in the case of drought. The unfertilised plots yielded over 80% less than in the average years. In the case of unfavourable nutrition (N, NP, NK) the decrease in the harvested main yield was 64%, while the negative effect was slightly less (63%) in the NPK and NPKMg treatments. 6. The relationships between rainfall during the vegetation period, N, P, K and Mg fertilisation and yield were characterised by second-degree correlations depending on the level of nutrition (O: R=0.5949***, nitrogen: R=0.5734***, NP: R=0.7635***, NK: R=0.5357**, NPK: R=0.6710***, NPKMg: R=0.7055***). The grain yield per mm in the case of optimum rainfall supplies ranged from 3.7 to 7.2 kg · ha-1, depending on the fertiliser rate (0:3.7, N: 4.6, NP: 6.1, NK: 4.8, NPK: 6.2, NPKMg: 7.2, treatment mean: 5.4 kg · ha-1). The natural rainfall was utilised better in the fertilised plots than in the untreated control (N: 24, NP: 65, NK: 28, NPK: 67, NPKMg: 95, treatment mean 46%). Supplementary magnesium fertilisation led to a 17% (1.0 kg · ha-1 · mm -1) increase in yield compared to the NPK treatment.
