Abstract

The effect of rainfall quantity and N fertilisation on the yield of rye was studied in five years (1964, 1966, 1968, 1970, 1972) of a long-term fertilisation experiment set up in 1962 on acidic sandy brown forest soil with alternate layers of clay material in Nyirlugos, East Hungary. The soil had the following agrochemical parameters: pH(H2O) 5.2-6.5, pH (KCl) 4.4-4.9, hydrolytic acidity 5.9-10.8, hy1 0.2-0.4, humus 0.4-0.9%, total N 20.6-48.0 mg · kg-1, AL-P 2O5 20-66 mg · kg-1, AL-K2O 20-100 mg · kg-1. The 2 × 16 × 4 = 128 treatments were set up in four replications in a multiple split plot design on a total of 512 plots. The fertiliser rates applied were 0, 30, 60, 90 kg · ha -1 nitrogen, 48 kg · ha-1 phosphorus (P 2O5), 80 kg · ha-1 potassium (K 2O) and 15 g · ha-1 magnesium (MgO). The main results can be summarised as follows: 1. On the basis of traditional and rye-specific rainfall deficiency values the years could be divided into average (1966), dry (1964, 1968, 1972) and wet (1970) years. 2. Without fertilisation the weather anomalies (drought, abundant rainfall) did not cause significant yield differences (average year: 1.63 t · ha-1, dry year: 1.51 t · ha-1, wet year: 1.47 t · ha-1). 3. In the case of poor (30 kg · ha-1) N supplies the yields ranged between 2.35 and 2.77 t · ha-1. In the average year the yield was more than 1 t · ha-1 higher than on the control plot, while dry and wet years led to yield reductions of 26 and 23%, respectively. 4. With a moderate rate of N fertiliser (60 kg · ha-1) the yields were almost twice those in the control. The damaging effect of drought was reduced from 26% with poor N supplies to 15%. Excessive rainfall reduced the yields by 29%. 5. At an N rate of 90 kg · ha-1 the yields were greater than 3.5 t · ha-1 in the average year, while this was reduced by 20% on average in the dry years and by 48% in the wet year. 6. In general close quadratic correlations could be demonstrated between the rainfall quantity during the vegetation period and the yield, depending on the nitrogen rate. The best yields of around 4.0 t · ha-1 were recorded when the natural rainfall amounted to 430-500 mm. Rainfall quantities in excess of 500 mm caused severe yield reductions.
