STUDY ON YIELDS OF GRASSES AND LEGUMES UNDER INFERTILE SOIL AT CHAIYAPHUM

Abstract

The experiment was carried out at Chaiyaphum Livestock Breeding station at  Chaiyaphum province, Northeast Thailand for 2 years. The 3 grasses x 4 legumes x 4 replicates were factorially arranged in a randomized complete block design.

Rootstocks of grasses. were planted at 50 x 50 cm while seeds of legumes were oversown at the rate of 25 kg/ha. Both grasses and legumes were cut at 10 cm every 40-50 days during wet season. Growth and dry matter yields of grasses and legumes were recorded.

The experimental results showed that Signal grass (Brachiaria decumbens) yielded highest during the dry season and had more adaptability to the experimental conditions than other grasses. Ruzi grass (B. ruziziensis) grow faster than Signal grass only during the early stages of development. Data on yields of all grasses and legumes were also presented.
