Extemp lettuce is an early-fruited Frieze-type endive variety from the Salanova line, developed by Rijk Zwaan. This variety features a vigorous, fast-growing plant with deeply lobed, light-green leaves up to 20 cm long. The average head weight ranges from 120 to 200 grams. The leaves are large, curly, crisp, and juicy, giving the product an attractive appearance and a pleasant delicate flavor. Extemp retains freshness and nutritional value for a long time, making it popular for both fresh marketing and processing. Extemp can be grown both outdoors and in greenhouses, including in flowing hydroponic systems. The variety performs exceptionally well in the summer season, showing high heat tolerance and productivity even under high solar activity and elevated temperatures. The plant is not prone to bolting, ensuring a stable yield and high product quality. Additionally, the lettuce exhibits high resistance to various diseases and pests: it is not susceptible to leaf necrosis, powdery mildew, or lettuce aphids, reducing the need for treatments and enhancing cultivation eco-friendliness. Thanks to these characteristics, Extemp is a reliable choice for farmers and producers aiming to obtain a high-quality and resilient lettuce harvest.
