Effect of cutting interval on yield and quality of two Panicum maximum cultivars in Thailand

Tanzania guinea grass [Panicum maximum cv. Tanzania (cv. Purple in Thailand)] has been grown in Thailand for over 20 years and has proven to be a high quality forage (Phaikaew et al. 2007). Mombasa guinea grass (Panicum maximum cv. Mombasa) was introduced to Thailand in 2007 and commercial seed production commenced in 2008 because of a demand for seed in central and South America (Hare et al. 2013). It is a larger and taller cultivar than Tanzania. A series of studies have been undertaken at Ubon Ratchathani University, Thailand, to study the agronomic differences between these cultivars. The effects of cutting were examined in the first of these studies.
