Farming Smarter started this project proposing that inter-row seeding could allow for taller standing stubble (which is proven to help increase yields in zero-tillage systems), improve depth control and seedling establishment. Past studies have found that seeding on-row reduced plant stand establishment in canola compared to seeding between the row and check plots. It was also discovered that canola yield was higher with the pillar laser disc/hoe openers compared to the steal paired tow and was not affected by the row placement. This study is a continuation of previous work and seeks to evaluate inter-row seeding by measuring seedling establishment and yield in relation to stubble location, stubble heights and seeding rates.
Two factor factorial treatment arrangement within an RCBD with four replicationsFactor 1: Type of seeding row opener with two types,
Factor 2: Seeding orientation with three levels,
The field trial was set up on large-size plots (approximately 50m x 1.93m).
Data was collected on several factors, including:
During the study soil temperature averaged very close in both seeding orientations, it did not affect the three parameters (canola plant stand count, weed intensity & yield)
This study found there was a 10 per cent reduction in plant count on the ones that were seeded on row in comparison to the crops seeded between the stubble.
The project shows that producers can decrease their seeding rates and maintain their yields with nothing more than standard GPS technology.
Based on the findings, it can be concluded that seeding canola crop between stubble rows from the previous crop with Pillar Lasers disc hoe type seeding row openers produced the highest canola plant stand and is therefore is most likely to benefit producers in establishing a healthy and profitable canola crop. This practice can be even more beneficial in improving canola plant emergence and initial crop establishment under dryland condition because of its high potential of improving soil moisture conditions and reducing wind and water erosion.
