When is maize planted

Maize yield farmer-driven contest-winner data provided the opportunity to produce a comprehensive planting date map for high-yielding maize across different US latitude groups. For this synthesis-analysis, both the contest-winner and literature datasets portrayed that planting date becomes a more relevant factor for high-yielding US maize systems when planting late with a shorter planting window duration in high- relative to low-latitudes.

Collected the data: NL. Contributed in critical revision of the article: IC. Final approval of the version to be published: IC.

Potential yield Maize is one of the most efficient plants at converting radiation into biomass 1. Maximising potential yield To maximise potential yield we need to maximise radiation interception.

Plant population. Crop monitoring Monitoring is important to maximise yield. Emergence to four leaves. Monitor for slug and bird damage Check for greasy cutworm and weeds - greasy cutworms feed at night by typically cutting and felling maize plants; there are spray options which give good control Deep soil cm N testing to plan for post-emergence fertiliser.

Selecting the correct variety is key and is dependent on the intended end use of the product. For anaerobic digestion varieties such as Fabregas, Ronaldinio and Barros should be used to ensure maximum yield as the main consideration, whereas starch content should be the main driver when growing as a forage crop. Varieties such as Kentaurus, Ambrosini and Kontender are more suitable for forage. Maize is generally sown mid-April time and harvesting is carried out towards the end of September or into October.

When drilling be aware of soil temperatures. For light soils the temperature must be 8 degrees Celsius for days and for heavier soils 10 degrees Celsius for 3 to 4 days should be observed. This ensures the best possible establishment of the crop. Adequate soil temperature is critical for successful maize cultivation.
