The results are given of 2-year sand culture trials with 3 levels of N, P and K in various combinations. The best growth was obtained with the highest N application rate, differential effects of the other nutrients being slight. Flowering was advanced by 10 and 15 days by high rates of N and P, respectively, but low N delayed flowering by over 2 months. Flower numbers were greatly increased by high N, and fruit set was enhanced by high N, P and K.
