Peas Research

Peas have a relatively short season and are a popular vegetable over the summer months. Most peas grown in New Zealand are eaten processed.

In 2015 the total tonnage grown was 66,500 tonnes and $84.8m FOB was exported.

Down Mildew control in peas
Date 2016-08-15 16:04:51
Downy mildew can significantly reduce the yield of peas in some seasons. In severe cases almost entire stands can be destroyed and yield reductions of over 4 tonnes/ha have been reported. Foilar fungicide treatments significantly reduced the incidence and severity of downy mildew but, although there were small increases in yield, these were not significant and the gross margins over the control were negative.
Improved pea production for sustainable arable farming development of ascochyta blight epidemics year 3 results
Date 2016-07-22 16:20:53
This report outline the project “Epidemic development of ascochyta blight” which completes the third and last year of work in the MAF Sustainable Farming Fund (SFF) project “Improved pea production for sustainable arable farming”. The main conclusion from this trial was that the sowing date had a major influence on final yield; early sown crops (August) had greater yields than later-sown crops (sown in September and October).
Field evaluations of effect of seed fungicide treatment on seedling establishment
Date 2016-07-22 16:20:52
This report outlines the project “Epidemic development of ascochyta blight”, which completes the third and last year of work in the MAF Sustainable Farming Fund project “improved pea production for sustainable arable farming”. Based on the findings we recommend that fungicide seed treatments should continue to be routinely used for peas because they provide worthwhile insurance against soilborne seedling diseases that can harm seedling establishment, and provide some protection against epidemics of downy mildew in young crops.
Effects of nitrogen on yield in Wairarapa pea crops
Date 2016-07-22 16:20:52
This trial was conducted to test the yield response of direct drilled peas to nitrogen in the Wairarapa region to support growers with their crop management plans. No significant benefit was demonstrated from the application of nitrogen fertilizer to pea crops for either yield or harvest index. The yield benefit found in two of the fertilized treatments from the trials this year was not significantly better than that of the unfertilized treatments.
Fungicide control of Ascochyta in peas
Date 2016-07-22 16:20:52
Ascochyte is a disease complex caused by three fungal pathogens. This research evaluated foliar fungicides for control of Ascochyta in peas over four seasons. The variable response to these fungicides suggests that a disease forecasting system will be essential if farmers are to get economic responses from the use of the fungicides tested in the trials.
