New Zealand farmers harvest approximately 400,000 tonnes of wheat each year. Wheat is used to produce high quality ingredients for the New Zealand food industry, contributing to millions of dollars in export revenues and is also a valuable food source for animals. FAR's wheat research is aimed at helping growers select appropriate cultivars and manage crop inputs in order to achieve the best economic and environmental outcomes.
20 by 2020
In New Zealand, current feed wheat production is approximately 9t/ha. FAR's 20 by 2020 project is aimed at increasing grower productivity and profitability by increasing feed wheat yields to 20/t ha by 2020. Ideas being investigated include optimum time of sowing.
Research collaborators in this project are NIAB TAG in the UK, and Plant & Food Research.

Irrigated autumn sown feed wheat yield potential: Time of sowing by wheat cultivar and plant growth regulation
Two wheat cultivars - Wakanui and KWW47 will be used for trials within this project. There are 4 aims:
1) to investigate the optimal time of sowing for high winter wheat yield,
2) to assess the agronomic performance of two late maturing wheat cultivars with contrasting disease and lodging resistance,
3) to investigate the effect of intensive and standard rates of PGR on crop canopy characteristics, lodging control and seed yield and
4) to quantify leaf number, tiller number, radiation interception, dry matter accumulation, stem carbohydrate content, stem number and harvest index from the different treatments.
Cereal Performance Trials
Soil type, weather patterns, disease susceptibility and access to irrigation are all factors which need to be considered when selecting wheat and barley cultivars. The Cereal Performance Trials (CPT), a cooperative effort between FAR, several of the major seed companies and the Flour Millers Association aim to deliver the latest trial results in order to help growers make these critical decisions. FAR manages CPT2 which is the second stage of cultivar testing where the commercial (and a few pre-commercial) cultivars are evaluated. CPT1, assessed the most favourable cultivars from seed companies and advanced breeders' material. CPT trials are run for both autumn and spring sown cultivars and the results are published and circulated to growers twice a year.
