Once more SPot Scotland has shown you can vastly reduce nitrogen use without seeing any negative impact on yield or crop quality. In fact, we have seen better yields when less nitrogen has been applied.
This factsheet provides results of nitrogen (N) and phosphorus (P) response experiments on sweetcorn (Zea mays L. var. rugosa) from work undertaken in AHDB Horticulture project FV 409, which was carried out during 2013 and 2014, to improve understanding of sweetcorn responses to N and P.
The AHDB Nutrient Management Guide (RB209) offers best practice guidance on the application of mineral fertilisers, manures and slurries to crops and grassland. All seven sections can be accessed from this page. Download section 1, below.
