In response to the research questions and the research conducted, the following conclusions can be made from the field pea trial at Raymond Hill.


·     The precision seeder caused significantly less soil disturbance, better plant establishment and greater production than the double disc seeder in this trial.


·     This is inconsistent with similar trials on canola and adzuki beans at Dubbo, which showed no significant differences between the biomass and yield between disc seeder and precision planter treatments, despite a difference in plant establishment.


The results of this trial show that the concept of using seed singulation or precision planting on field peas is technically feasible. The results also suggest an improvement in plant establishment and production can be achieved compared to using a double disc seeder for sowing. Better plant establishment and biomass will also assist to increase weed competition.


Further research into the cost of a precision planter is required before it is established as economically feasible. This information will assist in understanding how the value of this technology will be perceived by the grains industry.








The field pea trial was part of a Commonwealth funded project called ‘Advanced seeding systems for enhanced erosion and weed control in broad acre cropping’. The project was funded through the National Landcare Program Innovation Grants and delivered by the Conservation Agriculture and No-Till Farming Association (CANFA).
