Other claims from this paper (11)
- Intervention effect Applied individually, N fertilizer gave a response of 6 per cent in Valencia orange.
- Intervention effect Applied individually, P fertilizer gave a response of 5 per cent in Valencia orange.
- Intervention effect Applied individually, K fertilizer gave a response of 23 per cent in Valencia orange.
- Intervention effect The total response to N, P and K applied simultaneously was 40 per cent, compared with 37 per cent predicted by sequential additivity and 34 per cent by simple addition.
- Intervention effect When N, P and K were applied together, the individual response to N was 8 in Valencia orange.
- Intervention effect When N, P and K were applied together, the individual response to P was 7 in Valencia orange.
- Intervention effect When N, P and K were applied together, the individual response to K was 26 in Valencia orange.
- Observation The interactions of K with P and of K with N were also sequentially additive.
- Intervention effect When N and P were applied together without K, a severe antagonism resulted, with a large yield decrease.
- Intervention effect Adding K to the N plus P treatment resulted in a 69 per cent yield increase.
- Observation Potassium was a limiting factor only for N and P together, not for N or P individually.
