Fifteen tropical grasses were evaluated for dry matter yield, plant chemical composition and persistence under the closed canopy of oil palm with three cutting intervals of 8, 12 and 16 weeks. Most grasses reached plateau production six months after initiation except Brachiaria decumbens under high cutting frequency and Axonopus compressus under low cutting frequency. The best dry matter yielder was Brachiaria decumbens (1727 kg/ha/year) followed closely by Brachiaria brizantha (1235 kg/ha/year), Paspalum conjugatum (1145 kg/ha/year), common guinea (1029 kg/ha/year), Digitaria setivalva (1007 kg/ha/year), Axonopus compressus (929 kg/ha/year) while Digitaria aristatum, Tanganyika guinea, Brachiaria ruziziensis gave average production (480 - 863 kg/ha/year). The rest of the grasses namely Trichoglume guinea, Kazungula setaria, Transvala digit, Rodd's Bay Paspalum, Cynodon plectostachyus and Bryan paspalum, produce negligible yield. Though Axonopus compressus and Paspalum conjugatum only produced respectively 54% and 60% DM yield of Brachiaria decumbens, they were the most shade tolerant and achieved similar nitrogen production as Brachiaria decumbens. None of the improved grasses were persistent under the palm canopy. All mineral concentrations in plant declined with time except the levels of phosphorus and magnesium. The Brachiaria spp. had the lowest level of all minerals while the guinea grass and the two natives were having the highest.

Trial on 4 grass species was conducted with different rates of fertilization on spoiled tin-mined land. It was concluded that the application of fertilizer was the only feasible alternative for revegetation in the spoiled tin-mined area. The performance of those grass species were quite well if given fertilizer. The appropriate rate of chemical fertilizer was 2500 kg/ha. (Modified author's abstract)

Nitrogen fertilizer as urea 46-0-0 at the rate of 78.2kg/ha was applied to a newly established sward of Panicum maximum, Panicum maximum cv. Hamil, Pennisetum purpureum and Brachiaria ruziziensis grown in Bangkok clay soil. The result showed that after defoliations (4 weeks) Panicum maximum cv. Hamil had the highest dry matter than the other tropical pasture grass species. (Authors' abstract)

Yields of 4 grasses and 4 legumes were investigated in Khon Kaen University Farm. The results showed that Guinea grass (Panicum maximum) and Signal grass (Brachiaria decumbens) had better adaptability under the local conditions than the other grasses. Guinea grass grew faster than Signal grass only during the first establishment year. Data on yields of the grasses and legumes are presented. (Modified authors' abstract)

Soil erosion and water runoff often occured in the undulated landform of Thai northeastern sandy soils. This study was conducted to determine the effect of vetiver grass (V. zizanioides) ruzi grass (B. ruziziensis) and verano stylo (S. hamata cv. verano) on water runoff and the loss of applied N, P. K fertilizers on sandy soil. Randomized completely block design was used with 4 replications and 5 treatments: bare land receiving 100 kg N, P, K/ha in the absence and presence of plant which was either vetiver or ruzi or verano stylo. A plot of 1 x 5 m in size was constructed on a land with 3% slope by fencing the area with galvanized sheet of 60 cm width which half of the sheet was buried in the soil. The plot runoff was collected in two receiver tanks of 80 cm in diameter and 100 cm depth and measured manually. The amount of N, P, K in the water were determined. The results showed that all three plants were indifferently effective in reducing the plot runoff by 52-67%. The effectiveness of vetiver depends on the width of the growing plant strip or its age. A strip of first year grown vetiver with 5 m width was as effective as that of the two year grown one with 1.5 m width. However, the first year grown vetiver with 1.5 m width was ineffective in reducing the plot runoff. About fifty percent decrease in the loss of applied N and P with the plot runoff was found in the presence of plants as compared to the bare land. However, loss of the applied K among treatments were not different.

The growth pattern, dry matter yield and certain nutritive parameters of ruzi grass and Graham stylo were studied during the growing season. The results indicated that crop growth rate, plant height and dry matter production of ruzi grass were higher than those of Graham stylo. In terms of herbage quality, crude protein and phosphorus contents of the legume were higher than those of grass during the growing period. In contrast, potassium and NDF were lower while ADF of both species were similar. However, crude protein, phosphorus and potassium levels of grass and legume decreased while NDF and ADF increased with maturity. (Authors' abstract)
