N x K x fungicide locations
Aims

Investigate responses to N and K, effects on leaf disease and interactions with a foliar fungicide.

Key messages
  • Unfortunately, crop was only sown at 40kg/ha, half the intended seeding rate. Low seeding rate and sever sub-soil compactions resulted in relatively low yields.
  • There were only low levels of yellow leaf diseases.
  • The site responded to N and K. With fungicide applied, there was a 0.7t/ha response to 85 kg N/ha (trt 3 v 4), and a 0.5t/ha response to 68kg K/ha (trt 2v9).
  • There was a significant response to fungicide at the high rate of N, but only with K applied. This suggests the benefits of fungicide are greatest where nutrient deficiencies are overcome.
  • Hectolitre weights were 74-77 kg/l and screening less than 5%
