Of all pests and diseases of potatoes in Great Britain, infestation by potato cyst nematodes (PCN), or eelworms, is the most damaging. Yield losses depend on pest populations, soil type and potato variety, with a range of 1–35% in trials, with infestations at 10–20 eggs per gram of soil.
Sampling and lab testing for PCN are vital, as, at low levels of infestation, no symptoms are seen in the field. This document provides a step-by-step guide to the sampling and testing process. If you have any further questions please contact your agronomist/advisor or your AHDB Knowledge Exchange Manager.
The starch, energy and intake characteristics of maize silage, together with its high dry matter yield potential, make it a good feed for beef cattle and sheep. This BRP manual includes information on growing and feeding maize and will help producers make the most of this potentially valuable crop
White and red clovers provide a good source of protein in ruminant diets, both when grazed or conserved, and have high intake characteristics.This manual outlines the advantages of including clovers in the farming system and the management needed to optimise their contribution to the farm business
Grass is the most important, yet often overlooked, resource for livestock production. Well-managed grassland provides the most economic feed all year round, either as grazing or conserved forage. This manual provides beef and sheep producers with advice on how to get the best from their grassland
