The study on growth and development of Panicum maximum cv. Hamil and Panicum maximum cv. Mombasa in Thanh Tri district, Soc Trang province
The experiment was implemented in order to assess the growth, development of grasses Hamil (Panicum maximum cv. Hamil) and Mombasa (Panicum maximum cv. Mombasa) in Thanh Tri district, Soc Trang province from May 2017 to May 2018. The experiment was completely randomized design, repeated 3 times in 3 different farmers with 100 m2/lot/variety. The results showed that, the germination rate after 14th days of the two grass was 83.27-85.81%. The growth rate in the rainy season is 1.77-1.86 cm/day, the regeneration rate in the rainy season is 1.99-2.06 cm/day, the dry season is 1.78-1.87 cm/day. Grass Hamil and Mombasa have high branching ability at 60 days after planting (13.6-15.7 branches), the fresh yield of Hamil grass and Mombasa grass was 21.40-21.68 tons/ha/cut, dry matter yield was 4.46-4.53 tons/ha/cut and the crude protein yield was 0.52-0.54 tons/ha/cut. Dry matter of Hamil grass and Mombasa grass contained 20.90-21.13%, in which crude protein accounted for 10.90-11.91%. The root survival through dry season of Hamil grass was 61.94% and 63.12%, sequentially. Thus, Hamil grass and Mombasa grass well growth and development in farming conditions in Thanh Tri district, Soc Trang province.
