Journal of Crop Science and Biotechnology   21(2) 113-119   Jun 2018   [Refereed]
Potassium (K) fertilizer closely affects both above-ground biomass production and radiocesium-137 (137Cs) uptake by plants from Cs-contaminated soil. Here we investigated the effects of low levels of K on aboveground biomass, 137Cs concentration, ...

Agronomy   8 17   Mar 2018   [Refereed]
The effects of two levels of manure application (184 and 275 kg N ha−1 year−1) on herbage yield, quality, and wintering ability during the cropping of a dwarf genotype of late-heading (DL) Napiergrass (Pennisetum purpureum Schumach) oversown with ...
Yukimi Nakata, Sachiko Idota, Manabu Tobisa, Yasuyuki Ishii
Agricultural Sciences   9(1) 129-140   Jan 2018   [Refereed]
It is ordinarily common for forage production in southern Kyushu to adopt a double cropping system, composed of summer forage crops (e.g. maize and sorghum) cultivated from late March to early September, and winter grass crops (e.g. Italian ryegra...
Satoru Fukagawa and Yasuyuki Ishii
Agronomy   8(2) 12   Jan 2018   [Refereed]
We investigated a new method for the establishment of dwarf Napiergrass by covering stem cuttings with soil in the winter season analogously to summer establishment in sugarcane. Three experiments were conducted, including measuring the labor invo...

Wulfenia   25(1) 140-157   Jan 2018   [Refereed]
Two Napiergrass genotypes, a semi-dwarf late-heading, DL, and a true dwarf (Taiwan Line 7734), were examined for grazing potential on foggage pasture in winter and for rotational grazing on fresh grass pasture in summer by Japanese-Black (JB) bree...

Year-round grazing potential of dwarf napiergrass pasture in southern Kyushu

日本草地学会2018年熊本大会   24 Mar 2018   日本草地学会
In our previous presentation (Kadwal et al., 2017), grazing potential on foggage dwarf napiergrass (Pennisetum purpureum Schumach) pasture was examined to find almost complete herbage consumption (>80% of herbage mass) by a 4-time grazing treatmen...
Grazing potential of foggage dwarf napiergrass pasture in southern Kyushu

日本草地学会2017年弘前大会   21 Mar 2017   日本草地学会
Phenotypic variation in napiergrass (Pennisetum purpureum Schumach) includes normal, semi-dwarf (DL), and dwarf (Taiwan Line 7734) types. We previously showed that dwarf and semi-dwarf genotypes had a contrasting canopy structure to normal napierg...
Yields from year-round triple cropping with a four-harvest system consisting of spring maize, millets, and heat-tolerant Italian ryegrass in southern Kyushu
Li Bo Kun, Yasuyuki Ishii, Yang Yingkui, Hirokazu Shinchi, Mitsuhiro Niimi, Sachiko Idota, Shegeki Nukudani, Keiko Nishimura
日本草地学会2017年弘前大会   21 Mar 2017   日本草地学会
A stable supply of domestic herbage is essential for continuous ruminant production. It has been demonstrated that a triple maize-barley (quadruple) cropping system can be employed in southern Kyushu, producing dry matter (DM) yield of 40 Mg ha-1 ...
Effect of temperature and underground storage of stem sections on emergence and establishment of nursery plants of dwarf Napier grass (Pennisetum purpureum Schumach)
Yusuke Iki, Yasuyuki Ishii, Satoru Fukagawa, Sachiko Idota
The 17th Asian-Australasian Association of Animal Production Societies Animal Science Congress   22 Aug 2016   Asian-Australasian Association of Animal Production Societies
Dwarf, late-heading (DL) Napier grass has a sufficient combination of yield and quality potential under both cut-and-carry and grazing uses. Since this species rarely produces viable seed, it must be propagated in the winter. The objective of this...
Yield and forage quality in the canopy of napiergrass genotypes
Hamid Kadwal, Yasuyuki Ishii, Yusuke Iki, Sachiko Idota
The 17th Asian-Australasian Association of Animal Production Societies Animal Science Congress   22 Aug 2016   Asian-Australasian Association of Animal Production Societies
Napiergrass (Pennisetum purpureum Schumach) has a range of phenotypic variation from real-dwarf, semi-dwarf to normal-tall genotypes. The study was conducted to determine yielding and quality attributes across several canopy strata for real-dwarf,...
