Abstract
A series of forty-two factorial field trials in 1959–62 tested the effects of 0·6 and 1·2 ewt./acre of N; 0, 1·2 and 2·4 cwt./acre of K2O; and 0, 2 and 4 cwt./acre of salt on sugar beet. Extra plots received 0 and 1·8 cwt./acre of N.On average, 0·6 cwt./acre of N was more profitable than 1·2 cwt./acre. There was a positive interaction between N and Na, and a lesser one between N and K; in presence of the heavy salt dressing, or the light salt dressing and potassium the optimum rate of nitrogen was 1·0 cwt./acre.
