O’Sullivan Agri is part of the Department of Agriculture’s Seed Certification Scheme. This guarantees our customers the best varieties available grown under Irish conditions and in compliance with very strict Departmental standards. We source the seed varieties that will give you the best results in terms of yield and grain quality. When choosing a variety,  we consider characteristics such as grain yield, straw yield and a good specific weight as important factors to examine. Other criteria such as resistance to lodging and good disease resistance – making for ease of management – will also influence variety choice.

We Stock:

  • Spring & Winter Barley
  • Spring & Winter Oats
  • Spring & Winter Wheat
  • Spring Beans


O’Sullivan Agri have supplied our own range of grass seed mixtures for many years. We have leading grass and clover mixtures, while we constantly search for new varieties and species that will benefit Irish farmers.

  • Mixtures are specifically designed for Irish conditions.
  • Varieties are chosen for yield, digestibility persistence and disease resistance.
  • All seed is tested and certified to the highest standard.


Growing fodder crops is an increasingly good way of cutting the production costs on farms. We understand that each farm has its own requirements, so we provide a variety of fodder crops including Fodder Beet. Alternative Forage Crops such as Fodder Rape, Sugar Beet, Stubble TurnipKale and Redstart are increasingly important to provide fodder to beef, sheep and dairy herds during the winter months. These crops may stretch the fodder already saved on a farm such as Silage and Hay, but also ensure that farmland is increasing its output in any calendar year. Why grow forage crops:

  • Increase your profitability.
  • Reduce reliance on purchased feed.
  • Excellent break crop.
  • Several cropping options.
  • Full traceability.


We also stock Rape and Leafy Turnip, Phacelia, Vetch and Tillage Radish for farmers sowing catch crops under the Department of Agriculture’s GLAS Scheme.
