Forage peas are produced worldwide on about 8 million hectares per year. It is highly esteemed animal feed and desirable crop in crop rotation. In Croatia, peas are produced on 1000 - 1500 hectares per year with an average yield of about 2.5 t / ha. During the growing season, forage peas are attacked by many harmful organisms. Control of harmful organisms in forage peas is very important because they can significantly reduce the yield and grain quality. Methods to suppressions harmful organisms consist of respecting crop rotation, achieving the recommended number of plants per area unit and applying of pesticides during the growing season. It is very important to control weeds in a timely manner, monitor disease development and prevent pest attacks. The Family farm Maričević has been producing forage peas for many years, and by improving agrotechnics, gaining experience and knowledge, it strives to achieve the best possible results in production, and special attention is paid to the control of harmful organisms. In 2021, the Family farm Maričević sowed forage peas on an area of 2 hectares. The crop rotation is satisfied by the choice of area for sowing. Weeds were controlled in two treatments, one of which was carried out with the aim of controlling broad leaf and the other narrow leaf weeds. By monitoring the weather conditions, it was assumed that they were not favorable for disease development, which was confirmed by crop control in the field. Pest suppression through two insecticide treatments prevented their attack and the negative impact on grain yield and quality. Implemented methods of suppressions harmful organisms in forage peas on the Family farm Maričević in 2021 have satisfactorily prevented potential damage that they can cause in the loss of yield and grain quality.
