Key Points

• The disc seeder has a higher average emergence than all tine seeder treatments

• There were no significant losses in crop performance when the disc seeder operated at higher speeds

​

Aim

The trial is aimed at comparing production costs, productivity and efficiencies at higher seeding speeds. While recording agronomic information such as plant establishment, chemical efficacy and/or damage, weeds throughout the growing season and yield variances.

​

Background

The so-called disc and strip system is gaining popularity in Australian broadacre cropping. Understanding the implications of changing to such a system is vital to growers in lower rainfall areas in particular. As a general rule, disc seeders are better able to handle higher stubble loads than tine and press wheel implements. The proposed demonstration trial will compare the two types of seeding implement in terms of both economic productivity and agronomic benefit.
