This study aims to compare the grain yield, gross return above fertilizer cost (GRAFC: (paddy sales)–(fertilizer cost)), and several parameters relating to the quality of white rice cultivated with different soil-specific nutrient management in 14 provinces where different soil types are distributed. The grain yield tended to increase with increased fertilizer application; however, the relationship between the fertilization rate and the yield was not linear in areas where clay soil dominates. In cases of popular varieties cultivated from the northern to southern province, the amount of fertilizer applied was up to 163 kg ha−1 (sum of N-P2O5-K2O), and the GRAFC and the fertilization rate showed a nonlinear relationship, with a peak of around 120 kg ha−1 fertilization. The nitrogen concentration recognized as a negative factor for the quality of rice tended to increase with an increasing fertilization rate, and the carbohydrate concentration and carbohydrate/protein ratio that are a positive factor for the quality were related negatively with the fertilizer rate. The amylopectin concentration in white rice was positively related with the carbohydrate concentration, which decreased with an increasing fertilization rate. The levels of fertilizer application required to achieve a higher yield, GRAFC, and the maintenance and improvement of parameters relating to grain quality were different.

Sago palm (Metroxylon sagu Rottb.) grows in well-drained mineral soil and in peatland with high groundwater levels until complete submersion. However, the published information on nutrient uptake and carbohydrate content in sago palms growing under waterlogging remains unreported. This experiment observed sago palm growth performance under normal soil conditions (non-submerged conditions) as a control plot and extended waterlogged conditions. Several parameters were analyzed: Plant morphological growth traits, nitrogen, phosphorus, potassium, and sugar concentration in the plant organ, including sucrose, glucose, starch, and non-structural carbohydrate. The analysis found that sago palm morphological growth traits were not significantly affected by extended waterlogging. However, waterlogging reduced carbohydrate levels in the upper part of the sago palm, especially the petiole, and increased sugar levels, especially glucose, in roots. Waterlogging also reduced N concentration in roots and leaflets and P in petioles. The K level was independent of waterlogging as the sago palm maintained a sufficient level in all of the plant organs. Long duration waterlogging may reduce the plant's economic value as the starch level in the trunk decreases, although sago palm can grow while waterlogged.

One of the key components that affects soil productiveness, plant growth, and crop quality is fertilization. The effect of fertilizer, both organic and chemical, on the extremely acidic (pH 4.10) sandy loam soil chemical properties, yield, and quality of white mugwort grown were evaluated in this study. The field experiment arranged in a randomized complete block design, with four replications was conducted in Prachin Buri province, Thailand. There were six treatments, no fertilization (control), chemical fertilizer (25-7-7 + 46-0-0) applied at 187.50 (66.56 N:6.77 P2O5:6.77 K2O kg ha-1) kg ha-1 and applied at 375.00 (133.12 N:13.13 P2O5:13.13 K2O kg ha-1) kg ha-1, chicken manure applied at 3.36, 6.72, and 10.08 t ha-1. After harvesting, application of chicken manure tended to increase soil organic matter compared to the control, however, the application of chemical fertilizer did not show the same effect. The fresh weight of white mugwort increased with the rise in both fertilizer levels. Chicken manure application at 10.08 t ha-1 produced the highest fresh weight at all times. The level of accumulated nitrate was significantly greater when fertilizer rates increased. In addition, the total phenolic content of the white mugwort fertilized with chicken manure was higher than that fertilized with chemical fertilizer. However, there was no association between the DPPH radical scavenging capacity at harvesting times and different fertilization. Based on the results, chicken manure applied at 10.08 t ha-1 gave the best yield and higher total phenolic content of white mugwort, which was probably due to the improved soil organic matter.

Taro beetle damage has recently been reported on Gau Island, Fiji, causing economic loss for the taro business. This significantly reduced farmers’ incomes and the cultural value of taro. Swamp taro cultivation is expected to be a solution to taro beetle damage. Even though studies investigating the mitigation of taro beetle damage in paddy fields are not common, taro beetles do not have the ability to go beyond a certain depth in muddy condition. This study investigated suitable wetlands for taro cultivation by using the topographic wetness index (TWI). The calculation also considered protection forest zones and accessibility as analyzed by RapidEye satellite images, normalized difference vegetation index (NDVI), and buffer function. Results showed that 26.03% of the island’s mass has potential for the development of paddy fields. Although the result was larger than predicted, there are differences between potential areas for each village. However, these areas were more than double size of the existing farmland of each village. Estimated yields corresponding to the potential areas were also presented in the study; these indicated that more than half of villages might be able to yield more than 0.50 t of taro production.

Sago palm (Metroxylon sagu Rottb.) photosynthetic performance was evaluated under drought conditions through leaf gas exchange and chlorophyll a fluorescence measurement. Drought has an impact on sago palm's leaf gas exchange parameters and its chlorophyll fluorescence of PSII. Stomatal limitations were found to be the main factor limiting photosynthetic activities of sago palm under drought conditions. Photosynthetic rate decreased following the inhibition in the PSII reaction center. Early detection of interference upon the efficiency of the PSII reaction center due to drought stress was recorded by chlorophyll a fluorescence measurement.[GRAPHICS].

Sago starch (Metroxylon sagu Rottb.) is one of the starches imported into Japan. Recently, sago starch has been promoted as a healthy type of starch because it is gluten-free and non-allergenic. This study aims to identify the factors affecting sago starch import demand during the period 1978-2017 in Japan by using a double logarithmic linear function. The study revealed that the price of sago starch, GDP, aging population rate and tariff-rate quota policy are significant factors influencing sago starch importation in Japan.

The distribution channel is vital in the sago business because it connects producers and consumers. In this paper, we identify the distribution channels of sago products and their functional classification. We found that the distribution of sago products, such as dried sago and roasted sago (sagu kotak), in East Java is classified as indirect distribution, which relies on intermediaries. Intermediaries such as distributors, wholesale agents, and retailers are primarily actors that directly coordinate buying, selling, storing, and distributing sago products from Riau and Maluku to consumers in East Java. In addition, our calculation showed that sago pudding has a highly profitable value-added process as compared to that of roasted sago.

Iron toxicity affects the growth and yield of rice plant. Overcoming the damage of rice production by iron toxicity requires furthermore researches from laboratory to field levels. Here, we study responses of rice genotypes to iron toxicity between vegetative stage in hydroponic and whole grow stages in the pot. The first experiment was hydroponic experiment using twelve rice genotypes which were growth in the Yoshida Solution with addition of 0.2 % of agar. Three level of iron was given at 0, 500 and 700 ppm. The second experiment was the pot experiment using alluvial soil added with 3.000 ppm of ferrous combine with four levels of potassium and the control on Cilamaya Muncul (tolerant), Inpara 8 (moderate tolerant) and IR 64 (susceptible). In hydroponic experiment, even though the symptom appeared obviously, the leaf bronzing score (LBS) of tolerant and sensitive genotypes were not different. Physiological traits were significantly affected by Fe treatment in all varieties. Then symptom and physiological traits were significantly correlated. Through the pot experiment, it was confirmed the tolerance of each varieties. However, we couldn’t see the correlation between the LBS on hydroponic and soil at this time. And the heading delay was new finding, but it depended on varieties. We also could see the possibility of potassium application to inhibit iron toxicity but still we need to explore how it works.

Photosynthetic performance of sago palm (Metroxylon sagu Rottb.) was evaluated in normal and waterlogged conditions. Net assimilation rate (AN), light response curve of net assimilation rate (AN/I) and pulse-amplitude modulation fluorescence vs. irradiance (PAM/I), leaf water potential, leaf chlorophyll content and leaflet area were measured. AN was higher in a particular period of waterlogging than in the normal condition. However, prolonged waterlogging (more than two months) negatively affected sago palm photosynthetic capacity. This was indicated by reduction in several photosynthetic parameters such as AN, maximum value of AN obtained at maximum irradiance (AN ( I max)), quantum yield at zero to 200 µmol m−2 s−1 irradiance (ϕ( I o_ I 200)), asymptotic photosynthetic efficiency (αo), and maximum electron transport rate (ETRmax). The plants experiencing waterlogging produced high qNmax and NPQmax values. Prolonged waterlogging period also caused significant reduction in leaf water potential (ψleaf) and photosynthetic pigments content. Normal soil conditions with a sufficient amount of water are preferable in order for the plant to generate higher photosynthetic capacity and facilitate stable sago production.

Photosynthetic activities of the sago palm (Metroxylon sagu Rottb.) were studied to find out its sensitivity to changes in ambient air temperature. The minimum ambient air temperature designed for the experiment was 25–29 °C, while the higher end was 29–33 °C. Several photosynthetic parameters were studied to support our analysis in sago photosynthetic activity, including diurnal leaf gas exchange, assimilation rate vs. CO2 concentration, leaf greenness, leaf chlorophyll content, and photosynthetic rate vs. irradiance. We found that sago palm photosynthetic activity tends to be more sensitive to minimum than to maximum ambient air temperature. The plants exposed to higher air temperatures had dark green leaf color associated with higher rates of diurnal photosynthesis, chlorophyll content, and rubisco limited photosynthetic activity. They also exhibited higher trend in optimum irradiance absorption level. Consequently, maximum light energy dissipation occurred at higher temperatures.

A rapid quantification method for leaf sodium (Na+) and potassium (K+) concentrations was developed using a compact ion meter. Leaf ion concentrations were evaluated for species of Vigna vexillata (L.) A. Rich. after two weeks of treatment with 0-200 mM of sodium chloride. To compare the ion extraction efficiency, extraction solutions of distilled water and ammonium acetate were tested. The ion concentrations of extracts obtained by both solutions were measured using an ion meter, and the values were validated using ion chromatography. For both extraction solutions, the ion meter values were highly correlated with those of the ion chromatograph. However, correlations between ion meter and chromatograph values were largely different for Na+ and K+. The rapid quantification of ion concentrations using an ion meter developed in this study was successfully utilized for evaluating differences in leaf Na+ concentrations, K+ concentrations, and K+/ Na+ ratio in species of V. vexillata.

In order to develop a high-yielding culture method for wheat we examined the effects of a higher top to basal nitrogen dressing ratio (HTBD) on the growth and yield of the new lodging tolerant variety "Satonosora" for two years. The reduced basal dressing accompanied with increased top dressing, increased the leaf area index (LAI) after jointing stage, and maintained a high net assimilation rate (NAR) during the late ripening period resulting in increased dry matter production. On the other hand, smaller stem number due to reduced basal dressing and plentiful nitrogen top dressing at the jointing stage were considered to alleviate competition of assimilate and nitrogen among stems and improved stem survival rate, resulting in both larger panicle number and panicle size. High NAR during the late ripening period might also increase the 1000 grain weight. As a result of the increased dry matter production and yield components, a HTBD increased the yield of wheat by 15 - 50%. On the other hand, some problems hindering practical use were clarified; delay of maturation, decline in the apparent quality, excess grain protein content, and acceleration of soil acidification.

Although Sago palm have been focused as bioenergy as well as foods, the production has decreased. In our previous study, we predicted the potential site of sago palm in Sulawesi Island, Indonesia. The total area was 1282 km2. The model for prediction of sago palm showed the maximum temperature of the warmest month was the most important variable affecting sago palm potential distribution. Climate change is also an important global issue for crop production. In this study, we predicted the future distribution and harvesting of Sago palm affected by the climate change using the Maxent model and it was compared with the current prediction that was predicted in our previous study.

Language：English Book type：Scholarly book

This book addresses a wide variety of events and technologies concerning the sago palm, ranging from its botanical characteristics, culture and use to social conditions in the places where it is grown, in order to provide a record of research findings and to benefit society. It discusses various subjects, including the sago palm and related species; differentiation of species of starch-producing palm; habitat, morphological, physiological and growth characteristics; culture and management; productivity of carbon dioxide; starch extraction and manufacture; characteristics and utilization of starch; and cultural anthropological and folkloristic aspects. Problems such as food shortages due to increasing populations, global warming and climate change, and decreasing reserves of oil and other underground resources, have become more pressing in recent years. In the context of these problems, the book examines the role of the sago palm in sustainable food production, in the manufacture of other foodstuffs, as a raw material for ethanol and in the manufacture of biodegradable plastics. In addition to academics, this book will be useful to researchers and government officials working for international agencies, national governments, municipalities, and other research organizations; technicians, researchers, managers, entrepreneurs, and others working in industries such as agriculture, plant production, food production, manufacturing, chemical engineering, energy production, and distribution.

Language：English

Sago palm (Metroxylon sagu Rottb.) is the most promising starch producing palm species. Sago palm accumulates around 200 kg starch or more per plant or in the trunk. This palm species is recognized as one of the crops used by human beings since ancient times. The growing area of sago palm spreads across several land conditions such as upland, tidal, and submerged areas which do not have a proper water drainage system. It can grow in swamp, alluvial, and peat soils where almost no other major crops can grow without drainage or soil improvement. It is adaptive to an extremely wide range of environmental conditions from brackish water to fresh water. However, its growth performance and starch yield vary depending on the growth environment such as soil types and water conditions. Considering the recent social backgrounds, namely a new competition between biofuel production and food production as well as demand for food diversification, the efficient use of carbohydrates from the sago palm and related species as well as predicted increase in the sustainable development and utilization of land in swampy areas are currently anticipated. This chapter provides a brief review on future prospects of sago palm growth and production in different soil conditions mostly in accordance with the publications from the Society of Sago Palm Studies.

Analysis of the diversity and phylogenetic relationships of Metroxylon palms in Oceania based on the 5S nr DNA sequence revealed that Vanuatu sago palm (M. warbrugii) was the second most diverse after sago palm (M. sagu). From the analysis using MaxEnt, in order to reduce the risk of endangered Fijian sago palm (M. vitiense), transplantation to potential suitable places in the inland where suitable habitats exist as well as coastal areas will be important as a conservation strategy. Considering the change in climate, it is estimated that the future suitable land for growth of M. vitiense will increase two to four times. In comparison of agronomic traits revealed that sago palm has a high productivity due to its high dry matter content in the pith and starch concentration, while the growth rate of Solomons’ sago palm (M. salomonense) is considered to be high.

ペンカジョアン村でのサゴヤシ研究センターの栽培実験地では、2016年当初に移植されたサゴヤシ苗（７２株）の生育調査を、また、2012年９月に移植したサゴヤシ株（159株）の生育調査を継続して実施しながら、優良苗の選抜方法の検討に着手している。一方で、サゴヤシの育苗センターの苗生産のために、実生からの苗生産に着手した。開花期の５個体を確保し、花序、花、結実等の生育観察をしつつ、結実した実からの実生苗の生産を準備している。これは、地域内からの苗の要請だけでなく、パプアからの苗の購入要請等に応えるためである。
一方で、ルウ地方（３県、１市）のサゴヤシを使ったサゴ・テクノパーク構想の支援も並行して行っている。2016年６月のパロポ市が実施したサゴセミナーには、研究分担者等を派遣して講演を行っている。また、７月にはこのルウ地方のサゴ・テクノパーク構想を実現させるために、内外の研究者や中央政府の関係者を招いて、国際サゴヤシシンポジウムをサゴヤシ学会の協力の下に開催している。
こうした一連の活動の中で、UNHASのサゴヤシ研究グループを組織化している。また、UNHASの院生やルウ地方の地元大学の若手教官連携し、サゴヤシ研究センターを中心に複数のサゴヤシの課題研究が実施されつつある。
また、研修プログラムも作成され、西パプア州の南ソロン県のサゴヤシの専門学校：AKNESSから学生１２名がペンカジョアン村のサゴヤシ研究センターの栽培実験地を使って、実習を行っている。

In the cultivation experiment site in the sago palm research base, We continue to research Morphological Leaf Growth for selecting excellent seedlings. Moreover, in order to respond to the request of a large number of seedlings from a local government in Luwu and a company engaged in greening project, we are starting to produce seedlings from seeds. Production of these seedlings from seeds was started by installing three towers (made by bamboo) for growing observation of seven sago palms at the flowering stage, with investigation of flowering and fruiting results. These results will be announced at the Sago palm conference to be held in June this year.

ペンカジョアン村でのサゴヤシ研究センターの栽培実験地では、2016年当初に移植されたサゴヤシ苗（７２株）の生育調査を、また、2012年９月に移植したサゴヤシ株（159株）の生育調査を継続して実施しながら、優良苗の選抜方法の検討に着手している。一方で、サゴヤシの育苗センターの苗生産のために、実生からの苗生産に着手した。開花期の５個体を確保し、花序、花、結実等の生育観察をしつつ、結実した実からの実生苗の生産を準備している。これは、地域内からの苗の要請だけでなく、パプアからの苗の購入要請等に応えるためである。
一方で、ルウ地方（３県、１市）のサゴヤシを使ったサゴ・テクノパーク構想の支援も並行して行っている。2016年６月のパロポ市が実施したサゴセミナーには、研究分担者等を派遣して講演を行っている。また、７月にはこのルウ地方のサゴ・テクノパーク構想を実現させるために、内外の研究者や中央政府の関係者を招いて、国際サゴヤシシンポジウムをサゴヤシ学会の協力の下に開催している。
こうした一連の活動の中で、UNHASのサゴヤシ研究グループを組織化している。また、UNHASの院生やルウ地方の地元大学の若手教官連携し、サゴヤシ研究センターを中心に複数のサゴヤシの課題研究が実施されつつある。
また、研修プログラムも作成され、西パプア州の南ソロン県のサゴヤシの専門学校：AKNESSから学生１２名がペンカジョアン村のサゴヤシ研究センターの栽培実験地を使って、実習を行っている。

焼畑農業とサゴヤシデンプン抽出を営んでいる伝統的農村が新しい農業としての水稲栽培を受け入れる要因について、インドネシア国南東スラウェシ州で調査を実施した。これを通して水稲栽培が持続されるための農村社会の変容要因についても分析した。調査の結果、水稲栽培は外部者(技術を持った移住民族等)から導入されたもので、水稲技術が定着するためには技術を持った人の存在が必要であることが判明した。また、水田が持続されない場合には、彼らにとって栽培が容易で、初期投資が少なく、かつ、換金性の高い畑作物や永年作物栽培に固守することが判明した。この理由としては伝統的農村で貨幣経済が浸透することより、農業がより専業化される傾向にあることが判明した。

本学実験圃場内の水田土壌を用いて、酸性土壌条件をつくり出すための方法、並びに指示薬を用いて視覚的に土壌pHの変化を調査する方法を検討するとともに、土壌pHに対する日本型イネ品種の生育反応の差異を調査比較し、以下の結果を得た。
1.土壌の酸性化とアルミニウム含量
(1)土壌酸性化の検討
埴壌土水田土壌(pH5.94)に硫酸(36N)を添加し、pHの変化を調査したところ、土壌100gのpH変化は次のような指数式で表せることが明らかになった。
y=5.834e^<-1.889x> R^2=0.922
(2)人工酸性土壌のアルミニウム含量
上記の方法でpH3.90〜5.94の範囲で5段階のphが異なる土壌を設定し、yUANの方法により置換性アルミニウムを測定したところ、pH5.94では検出されず、pH3.90では11.85mg/100gの置換性アルミニウムが検出された。
2.ブロムフェノールブルーによる土壌pHの観察
通常ブロムフェノールブルーは0.1gを20mlのエタノールに溶解した後に100mlに調製するが、イネの発芽趣旨は極僅かでもエタノールを含む培地では生長が著しく阻害された。そこで、エタノールを用いずにブロムフェノールブルーを調製し、土壌に混入したところ、土壌は十分に染色され、pHの違いがはっきりと観察された。
3.土壌pHに対する日本型イネの生育反応の品種間差
日本型イネ10品種を用いて、上記のphの範囲における草丈、最長根長、地上部・地下部乾物重を調査したところ、pHに対する核形質の反応から次の3グループに分類できた。
・対アルミニウム性小:地上部・地下部とも生育阻害が小さい(ツクバハタモチ)
・対アルミニウム性中:地上部のみ生育が阻害される(コシヒカリ、ヤマヒカリ)
・対アルミニウム性大:地上部・地下部とも生育が阻害される(越路早生、他)

イネの葉身構造変化を伴わずに,光合成機能を高め得る施肥法の開発を指向し,一時的に高濃度の窒素肥料を施用した場合の影響を調査した.その結果,2300ppmN,12時間の処理によって,葉身の薄化拡大を伴わないで葉面積当たり窒素含有量を高め得ることが明らかになった.一方,この処理による各部位の乾物重当たり窒素含有量の変化を調査したところ,葉身部に比較して葉鞘+茎部においてその増大が大きいことが,また,根部では他の部位に比べて増大程度が小さいことが明らかになった.そして,この処理を移植直前に行った苗を移植したところ,小肥条件において移植後約2〜3週間の純同化率,相対生長率が高まり,有効化する低次分げつの発生が促進され,穂数の増加を通じた1株穎花数の増加によって増収につながることが明確になった.さらに,本処理の効果は品種によって異なり,比葉面積が本来的に小さい品種において,処理による葉面積当たり窒素含有量の増大程度が大きく,移植後の生育促進効果が大きいことが明らかになった.他方,一時的な高培養液濃度条件下において,品種の違いによる窒素吸収の差異を窒素形態別に調査したところ,NH_4^+吸収量には統計的に有意な品種間差は認められなかった.それに対して,NO_3^-吸収量には明確な品種間差が認められること,また,その差異はインド型,日本型という生態型の別とは対応関係がないことが明らかになった.

アンモニア処理による麦稈の消化率の増加は、その柔細胞壁や厚壁細胞壁の内腔表面を覆う膜状構造の脆弱化や細胞壁内部への機械的損傷による、ルーメン微生物の飼料片への付着助長と密接に関連していることを明らかにした。この強固な膜状構造は木材の仮導管細胞壁に認められるwarts layerとは形状的に異なることから、個々の細胞が枯死する時に生活残渣とおぼしき堆積物が細胞壁内腔く覆ったものであることを電顕法で明らかにした。また、アンモニア処理稈ATAg染色による呈色性の低下を認め、無処理ならびにアンモニア処理稈からの水ならびにメタノール抽出区分の成分組成やIR分析から、ヘミセルロース側鎖に置換するアセチル基の解離などによる構造の単純化が呈色反応試薬に対するsensitivityの増加をもたらしているとし、アンモニア処理による構造性多糖の溶解と消化性改善効果との関係を否定した。アンモニア処理稈と無処理稈への粉体X線回折において、アンモニア処理によるセルロース結晶化度の低下(約20%程度)が認められた。これまで、水酸化ナトリウム処理やアンモニア処理によるセルロース結晶性への影響は認めておらず、本研究において初めて、その作用機作として解明された。さらに細胞壁の保水性や膨潤性の増大(アルカリ加水分解による効果)も観察された。両処理稈から抽出した磨砕リグニンの物理化学的特性と組織細胞壁のVis/UV顕微分光解析を行い、その作用効果は、主として、リグニン末端アルデヒド基への求核反応によること、平均分子量、フェノール性水酸基、メトキシル基などの基本骨格への影響はきわめて微小であることを明らかにした。
以上のことから、ルーメン微生物の飼料片への付着助長、セルロースの非結晶領域の拡大や細胞壁の膨潤性の増大とがアンモニア処理による大麦稈の消化性改善と密接に関連していることを明らかにした。
