  author={C. Phaikaew and G. Nakamanee and S. Intarit and S. Tudsri and Y. Ishii and H. Numaguchi and E. Tsuzuki},
Two experiments were carried out with the intention of determining the optimum rate of N application for seed production of Paspalum atratum in north-east and northern Thailand. Experiment 1 measured the effect of 5 N rates (0, 100, 200, 300 and 400 kg/ha/yr N) on a fertile clay soil at Pakchong and Experiment 2 measured the effects of 3 N rates (0, 125 and 250 kg/ha/yr N) on infertile sandy soils at 3 sites (Lampang, Chiang Rai and Prae provinces). The response of seed yield to N application… Expand

Practical aspects of grass forage seed production and quality with particular reference to planting row spacing and nitrogen fertilization in tropical regions: A review
In general, seed growers had better to sown seed in row than broadcasting and row spacing of 50-80 cm can be recommended for seed production depending on grass species or cultivars, and applying fertilizer nitrogen to seed crops has implications for yield component dynamics such as tiller increasing, number of fertile tillers, floret per spikelet, and seed per head and ultimately increases seed yield and quality.

Seed and forage performance for an elite group of Paspalum notatum intraspecific hybrids
There were differences among genotypes, years and seasons for most of the variables assessed, and different performances for the traits allowing different patterns of seasonal forage yield, flowering period, seed yield and quality. Expand
Influence de l'écartement et de la fertilisation azotée sur le rendement et la qualité des semences de Brachiaria ruziziensis en climat tropical sub-humide
Cette plante est originaire des zones humides de l’est du Congo, du Rwanda and du Burundi and se développe en s’enracinant aux nœuds, ce qui assure une couverture rapide du sol en conditions favorables. Expand


Effects of plant spacing and sowing time on seed yield and seed quality of Paspalum atratum in Thailand
P. atratum has a long-day requirement for induction of flowering, and there was a tendency to obtain higher yields of good quality seed from the wider row spacings of 100 and 125 cm in all 3 years. Expand
Effect of nitrogen on production of Paspalum atratum on seasonally wet soils in north-east Thailand
Four trials were conducted in north-east Thailand to examine effects of nitrogen fertilisers and cutting frequencies on growth of Paspalum atratum (cvv. Hi-Gane and Ubon) on infertile, low lying,Expand
Influence of time and level of urea application on seed production of paspalum plicatulum at mt cotton, south-eastern queensland
All components of seed yield-tiller density, tiller fertility, raceme number and seed number, and seed size-were influenced by external nitrogen supply, and Nitrogen applications during the vegetative and floral initiation stages were most influential. Expand
Maximising seed yield and seed quality of Paspalum atratum through choice of harvest method
A 3-year trial to determine the most suitable method of handharvesting Paspalum atratum seed in north-east Thailand found that T5 gave the highest seed yields, but required a high level of precision in determining optimum harvest date. Expand
Method and time of establishing Paspalum atratum seed crops in Thailand
Seed crops of Paspalum atratum cv. Ubon established by sowing seed produced no seed at all in the first year of establishment in Thailand. By comparison, seed crops planted with tillers at theExpand
Urea application and time of harvest effects on seed production of Setaria anceps cv. Narok
Three levels of urea (50, 100 and 200 kg N ha-1 crop-1) and three methods of application were tested on four irrigated crops of Setaria anceps cv Narok grown for seed on a grey-brown podzolic soil, and inflorescence density exerted the primary control over seed yield. Expand
Effect of dolomite and sowing rate on plant density, yield and nutritive value of Paspalum atratum
Three experiments were conducted with the perennial pasture grass Paspalum atratum cv. Suerte at Ona, Florida. In Experiment I, Suerte was evaluated in 1992–1993 on a Pomona fine sand for responsesExpand
Seed production and its components in bred populations and cultivars of winter-green Setaria sphacelata at two levels of applied nitrogen fertiliser
Nitrogen fertiliser had a marked positive effect on seed production, inflorescence numbers, tiller fertility, basal tiller density, and inflorescence length in all populations. Expand
Effect of clipping on yield and nutritive value of 'suerte' Paspalum atratum
When rotationally grazed, Suerte should have a 20- to 40-d rest period between grazings to provide high DM yield and nutritive value, and both crude protein (CP) and in vitro organic matter digestion (IVOMD) decreased linearly over clipping intervals. Expand
Seed yield and its components of Brachiaria decumbens cv. Basilisk, Digitaria milanjiana cv. Jarra and Andropogon gayanus cv. Kent in north-east Thailand under different rates of nitrogen application
Gamba grass ( Andropogon gayanus ), with its drought-resistant characteristics, high dry matter production, high seed production and quality and low nitrogen requirement for seed production is a useful addition to pasture options for north-east Thailand. Expand
