The Nafferton HMC Field Trials

NEFG is managing three HMC field trials at Nafferton farm: a fertility trial, varieties trial and tillage trial.

The Fertility Trial

The HMC fertility trial is also a component of NEFG’s contribution to the DEFRA-funded Sustainable Intensification Platform. This experiment ran for two growing seasons (Year 1: 2014-2015; Year 2: 2015-2016) in the Quarry multi-factorial field trials. The experimental design includes:

  • Four varieties of spelt; four varieties of rye
  • Five fertility types (Mineral N, Biogas Digestate, Cattle Slurry, Composted FYM, Green Waste Compost)

The Year 1 trail was sown October 2014 and harvested September 2015. The Year 2 trial was sown October 2015 and harvested September 2016.

The Variety Trial

This experiment will run for two growing seasons (Year 1: 2015-2016; Year 2: 2016-2017) in the Quarry multi-factorial field trials. The experimental design includes:

  • Three varieties of spelt and one variety mixture (of 3 spelt varieties); three varieties of rye and one variety mixture (of 3 rye varieties)
  • Three fertility levels (zero: 0kgN/ha; low: 50kgN/ha; high: 100kgN/ha) Mineral N
  • Two crop protection treatments (Fungicide; No Fungicide)

The Year 1 trial was sown October 2015 and harvested September 2016. The Year 2 trial was sown October 2016.

The Tillage Trial

This experiment will run for two growing seasons (Year 1: 2015-2016; Year 2: 2016-2017) in the East Hemmel multi-factorial field trials. The experimental design includes:

  • Two varieties of spelt; two varieties of rye
  • Two cultivation practices (Conventional; Minimum Tillage)
  • Two weed control systems (Herbicide; Mechanical Control)
  • Two fertility types (Composted FYM; Mineral N) both at 100kgN/ha

The Year 1 trial was sown October 2015 and harvested September 2016. The Year 2 trial was sown October 2016.
