Tractor cultivating a field

Crop establishment is a critical phase in agriculture that involves the process of establishing crops in the field to ensure their successful growth and development.

This phase sets the foundation for the entire crop production cycle and can significantly impact yield and overall agricultural productivity. Here are key points to consider regarding crop establishment:

  1. Preparation of Land: The first step in crop establishment is preparing the land for planting. This involves tasks like plowing, harrowing, and tilling to create a suitable seedbed. Proper land preparation helps improve soil structure, aeration, and drainage.

  2. Seed Selection: Choosing the right type of seeds is crucial. Farmers select seeds based on factors such as crop variety, quality, disease resistance, and adaptability to local conditions. High-quality seeds have a better chance of germination and producing healthy plants.

  3. Sowing: Sowing is the act of placing seeds in the soil. It can be done manually, using traditional methods like broadcasting or dibbling, or with modern machinery like seed drills. Proper seed placement ensures even spacing and depth, which is essential for uniform crop emergence.

  4. Seeding Rate: Determining the appropriate seeding rate, or the number of seeds to be sown per unit area, is important. This rate varies by crop type and local conditions, and it affects crop density and competition for resources.

  5. Seedbed Preparation: After sowing, it's important to ensure good seed-to-soil contact. Adequate soil moisture and firm seedbeds help facilitate germination and early root development.

  6. Seed Treatment: Treating seeds with fungicides, insecticides, or growth promoters can protect them from diseases and pests and promote healthy plant growth. This is especially important in preventing seedborne pathogens.

  7. Crop Rotation and Crop Diversity: Rotating crops and diversifying plant species in a field can help reduce the risk of soil-borne diseases and pests. It also improves soil fertility by varying nutrient demands.

  8. Weed Management: Effective weed control is essential to prevent weeds from competing with crops for nutrients, sunlight, and water. Methods include mechanical cultivation, herbicides, and mulching.

  9. Irrigation: Adequate and timely irrigation is critical, especially in regions with irregular rainfall patterns. Proper moisture levels support germination and early crop growth.

  10. Monitoring and Management: Regular monitoring of crop establishment is essential to identify and address issues like uneven germination, pest infestations, or nutrient deficiencies. Adjustments may be needed to optimize crop growth.

  11. Environmental Factors: Weather conditions, temperature, and climate play a significant role in crop establishment. Extremes in temperature or adverse weather events can affect germination and early growth.

  12. Post-Emergence Care: Once crops have emerged, continued care is necessary, including nutrient management, pest and disease control, and appropriate cultural practices to maximize yield potential.

  13. Conservation Agriculture: Some farmers adopt conservation agriculture practices that aim to minimize soil disturbance during crop establishment to reduce erosion and maintain soil health. For example, direct drilling, intercropping, use of cover crops and others. See the agroecology and regenerative agriculture pages for more information and resources.

In summary, successful crop establishment involves a combination of careful planning, proper seed selection, suitable land preparation, and ongoing management practices to create optimal conditions for crop growth. It sets the stage for the rest of the growing season and significantly influences overall crop yield and quality. Farmers must adapt their approaches to specific crop types and local environmental conditions to achieve the best results.

If you are running an on-farm trial for harvest 2022 comparing cultivation or drilling practices, or you are considering such a trial for harvest 2023, please get in touch. ADAS are seeking to bring together farmers who are testing cultivation practices to enable sharing of experiences and trial results, and we can offer some staff resource to assess treatment effects on crops and analyse yield maps, to get the most value from these farm trials.

The Role and Position of Sunflower in UK Agriculture

An ADAS report to DEFRA in 1998 highlighting key trends and research priorities for the sunflower industry in the UK Sunflowers (Helianthus annuus var. macrocarpus) are in high demand due to the culinary, confectionary, bird-seed and industrial uses of their seeds (and thus oils), in addition to the popularity of the flowers in horticulture. At the time of this report in 1998, the UK imported ~350,000 tonnes of seed annually.  Whilst sunflower can be grown in the UK, there are a number of challenges including limited drilling dates to comply with soil temperature requirements, and careful monitoring of a range pests and diseases that sunflower is susceptible to. Further risks such as a late harvest time and the possibility of sunflower itself becoming a weed in following crops meant many farmers were not considering growing sunflowers on their farms. Based on a survey of UK farmers (including both sunflower growers and non-growers), the key factors reported that would encourage more UK farmers to adopt sunflower crops were… To convince farmers of profitability Guaranteed establishment of the crop Earlier harvests Good disease and weed control More information on growing the crops This project provided a comprehensive review of growing sunflower as an arable crop in the UK.  You can find the entire report linked at the bottom of this article (including historical and market information on sunflowers) but some of the key sections are highlighted here. Note all information is accurate for the time of this report (1998).

Living Mulch

Interest is growing in using legumes like lucerne or clover as a permanent understory to cereal crops to provide nitrogen through the season.

Risky Crops

Certain crops (potatoes, sugar beet, maize, field vegetables) within a wider arable rotation pose increased risk of soil loss or degradation. Often described as ‘risky’ these crops may require additional management to ensure that field conditions are favourable and that there is no long-term disruption to soil functionality or structure.

Basic tags

Simple meta tags.

The text to display in the title bar of a visitor's web browser when they view this page. This meta tag may also be used as the title of the page when a visitor bookmarks or favorites this page, or as the page title in a search engine result. It is common to append '[site:name]' to the end of this, so the site's name is automatically added. It is recommended that the title is no greater than 55 - 65 characters long, including spaces.
A brief and concise summary of the page's content, preferably 150 characters or less. Where as the description meta tag may be used by search engines to display a snippet about the page in search results, the abstract tag may be used to archive a summary about the page. This meta tag is no longer supported by major search engines.

Twitter Cards

A set of meta tags specially for controlling the summaries displayed when content is shared on Twitter.

Notes:
  • no other fields are required for a Summary card
  • Photo card requires the 'image' field
  • Media player card requires the 'title', 'description', 'media player URL', 'media player width', 'media player height' and 'image' fields,
  • Summary Card with Large Image card requires the 'Summary' field and the 'image' field,

Do not re-use the title text as the description, or use this field to describe the general services provided by the website. The string will be truncated, by Twitter, at the word to 200 characters.
By default Twitter tracks visitors when a tweet is embedded on a page using the official APIs. Setting this to 'on' will stop Twitter from tracking visitors.
The URL to a unique image representing the content of the page. Do not use a generic image such as your website logo, author photo, or other image that spans multiple pages. Images larger than 120x120px will be resized and cropped square based on longest dimension. Images smaller than 60x60px will not be shown.
