In order to understand the factors that influence lucerne hay quality and yield, it is necessary to have a basic understanding of the biology of the lucerne plant. As the plant matures, the stems become more lignified in order to support the plant as it grows heavier during flowering. The stems, rather than the leaves, also begin to make up a greater proportion of the plant. This results in higher yield, but lower quality.
The lucerne also takes longer to dry due to the thicker stems, which in turn causes increased leaf loss due to shattering (lucerne leaves dry out three to five times faster than the stems). The main objective of lucerne hay production should therefore be to strive for the ideal balance between yield and quality.
RAIN DAMAGE
The extent of reduction in yield and quality of lucerne hay depends on heat, irrigation, cutting schedule, harvest management and weather patterns. Of these, harvest management has by far the greatest impact on forage quality. Moreover, it is under the direct control of the grower. Producing lucerne hay for maximum yield and quality requires an understanding of how environmental and management factors influence crop growth and development.
The smallest amount of untimely rain can postpone the harvesting process, causing rapidly maturing lucerne to decline in quality very rapidly. Rain just before cutting slows down drying after cutting, as the soil remains moist despite sunshine and low humidity. However, rain before harvesting is only one potential problem. Even larger difficulties can occur when it rains after cutting.

New farmers' seedling pitfalls
Inexperienced farmers may be tempted to grow seedlings from seed themselves, but they have much to gain by trusting a seedling grower at a nursery to perform this task for them instead
South African avocado production: a success story
Avocado production in South Africa has expanded markedly since the industry's humble beginnings over 80 years ago. From a small grove planted in 1938 in what was then Nelspruit, the industry has blossomed to seven million trees planted on 20 000ha. Dr Guy Witney, project manager at Great Brak Avos, spoke to Annelie Coleman about the country's avocado production.
Unlocking value through livestock exports
Exporting livestock might sound like a daunting business that's better left for big companies, but Gerrie Ferreira, who farms near Oudtshoorn in the Western Cape, has been doing it successfully for almost 30 years, sometimes in partnership with other breeders. He spoke to Glenneis Kriel about the huge potential this market holds, and offers some advice for farmers who are contemplating going this route.
An agribusiness's dedication to community upliftment
For agribusiness NWK, located in Lichtenburg, North West, corporate social investment is an important part of creating a positive influence alongside financial returns.

Foreign investment: agriculture maintains its appeal
South Africa remains a popular destination for foreign investors, despite an often negative outlook from its citizens. It is a gateway to Africa, and with its counterseasonal production to the Northern Hemisphere and favourable weather, local agriculture is especially well placed to attract foreign interest, bringing with it hope for rural communities
The real value and message of COP29 for SA agriculture
While the 2024 Conference of the Parties may have disappointed those who hoped for real progress, it's more important for South African agriculture to highlight its role in carbon mitigation
