Leda (Eucalyptus deglupta) is one of fast growing species that prospecting for revegetation in post mined area. Leda is able to grow in poorly soil nutrient. The aim of this research is to analyze the effectiveness of AMF and P fertilizer on growth and P uptake of leda seedling. This research was conducted in split plot in Completely Randomize Design (CRD). The application AMF as a main plot consisted of 5 levels, namely M0 (control), M1(AMF from rubber plantation), M2 (AMF from primary forest), M3 (AMF from oil palm plantation), and M4 (AMF from natural rubber). The rock phosphate as subplot, consisted of three levels, such as 0 g P (P0), 2 g P (P1), and 5 g P (P2). The result showed that interaction between AMF from rubber plantation and 2 g of rock phosphate significantly gave the best effect for height and diameter of Leda while interaction between AMF-primary forest (M2) and P1 (2 g of rock phosphate) reach the best of the total dry weight. Both AMF from primary forest and oil palm plantation that combined with 2 g of rock phosphate give the best effect but was not significantly different for P uptake and P uptake efficiency.Key words: amf, growth, miychorrhiza, leda, p uptake, p efficiency

In a phytotron experiment, wheat was grown under two levels of atmospheric CO<sub>2</sub> [ambient (385 ppm) vs. elevated (650 ppm)], two levels of temperature (ambient vs. ambient +3&deg;C) superimposed with three levels of phosphorus (P) fertilization: 0, 100, and 200% of recommended dose. Various measures of P acquisition and utilization efficiency were estimated at crop maturity. In general, dry matter yields of all plant parts increased under elevated CO<sub>2</sub> (EC) and decreased under elevated temperature (ET); however, under concurrently elevated CO<sub>2</sub> and temperature (ECT), root (+36%) and leaf (+14.7%) dry weight increased while stem (&ndash;12.3%) and grain yield (&ndash;17.3%) decreased, leading to a non-significant effect on total biomass yield. Similarly, total P uptake increased under EC and decreased under ET, with an overall increase of 17.4% under ECT, signifying higher P requirements by plants grown thereunder. Although recovery efficiency of applied P fertilizer increased by 27%, any possible benefit of this increase was negated by the reduced physiological P efficiency (PPE) and P utilization efficiency (PUtE) under ECT. Overall, there was ~17% decline in P use efficiency (PUE) (i.e. grain yield/applied P) of wheat under ECT. &nbsp;

Oil Palm Plantation

Indonesia is one of the largest crude palm oil (CPO) producing countries in the world and at the same time have experienced high levels of deforestation. The link between deforestation and expansion of oil palm plantation has been a source of controversy, which has been exacerbated by the lack of objective quantitative information on the nature of land use and land cover change and the expansion of oil palm plantations.  This report provides an independent analysis of land use and land cover change for a broad range of land cover classes for five main Islands in  Indonesia, namely Sumatra, Java, Kalimantan, Sulawesi, and Papua based on Landsat TM satellite images. Visual analysis and on screen digitizing methods were employed to create a nation-wide land cover classification that spans two decades (1990 to 2010). Three temporal epochs (1990 to 2000, 2000 to 2005 and 2005 to 2010) correspond to a period of time with significant changes in land cover and land uses in Indonesia. Expansion of oil palm plantation in Indonesia shows that most of the expansion exists as a follow on transition from disturbed forest (secondary forest), agricultural lands (mainly rubber plantation), and low biomass land cover types, including shrub land and grassland than formerly reported to be majority from undisturbed forest (primary forest).

This study aimed to determine the effect of arbuscular mycorrhizal fungi (AMF) and phosphate (P) fertilizer on the nutrient content, phosphate uptake and in vitro digestibility of alfalfa (Medicago sativa L.).The research was conducted at green house of Forage and Pastures Science Laboratory, Faculty of Animal Science Universitas Gadjah Mada. The experiment was arranged in Completely Randomized Design using 3x4 factorial patterns with four replications. The first factor was dosage of phosphate fertilizer SP 36 (0, 60, and 120 kg/ha). Second factor was the dosage of AMF (0, 0.8, 1.6, and 2.4kg/ha). The variable measured was nutrient contents (crude protein, dry matter, and organic matter), total P uptake and dry matter and organic matter in vitro digestibility. The results showed that the interaction of AMF and P fertilizer had no significant effect on crude protein and total P uptake, but highly significant effect on the parameters of dry matter, organic matter and dry matter and organic matter in vitro digestibility.

Summary Oil palm is mostly cultivated in acid soil. The growth constraint of plant in acid soil is the limited availability of phosphorus (P) nutrient. Improvement of root system morphology and architecture have an important aspect since P is immobilized nutrient. Colonization of oil palm by rrbuscular mycorrhizal fungi increase the P uptake of plant. However, there is no information related to the effect of AM fungal colonization on oil palm root morphology and architecture.        A research has been conducted to asses the effect of colonization of two species of AM fungi on root system morphology and architecture of oil palm seedling. The research was conducted using Cikopomayak acid soil as medium in simple glass chamber. The plant material was from Indonesian Oil Palm Research Institute, Medan while AM fungal inoculum was produced using pot culture. Six treatments assesed are combination of three levels of  AM fungi inoculation (without inoculation with, Acaulospora tuberculata and Gigaspora margarita) and two levels of  fertilization (without, and with fertilizer). The result showed that colonization of AM fungi could change the root system morphology, and root architecture. The root fresh weight, root dry weight, length, and volume were significantly higher with the AM fungi colonization especially A. tuberculata inoculation. However, specific root weight was not significantly different between inoculated and uninoculated. The enhancement was significantly observed 26 weeks after inoculation. Biside that, proportion of secondary root of oil palm inoculated with AM fungi was higher compared to primary root. Fertilization tend to reduced root growth. Fertilization reduced significantly root shoot ratio of inoculated as well as uninoculated seedlings. The rooting volume was higher in inoculated seedling compared to uninoculated. The highest enhancement of N, P, and K uptake was observed 26 weeks after inoculation. The better root morphology and architecture might be one mechanisms of AM fungi colonized oil palm seedlings in increasing P uptake. Ringkasan Umumnya tanaman kelapa sawit ditanam pada tanah masam. Hambatan pertumbuhan tanaman pada tanah masam adalah terbatasnya ketersediaan nutrisi P (fosforus). Oleh sebab itu perbaikan sistem morfologi dan arsitektur akar memiliki aspek yang penting disebabkan P merupakan nutrisi yang tidak mudah bergerak. Kolonisasi tanaman kelapa sawit dengan cendawan  mikoriza arbuskula (CMA) akan meningkatkan penyerapan P oleh tanaman.  Namun, hubungan antara simbiosis  CMA dengan arsitektur perakaran kelapa sawit belum diketahui. Penelitian ini dilakukan untuk mempelajari pengaruh kolonisasi dua spesies CMA pada sistem morfologi dan arsitektur akar bibit tanaman kelapa sawit. Percobaan  dilakukan menggunakan tanah masam Cikopomayak yang mengandung Al tinggi sebagai medium dalam kultur pot kaca yang sederhana. Kecambah kelapa sawit berasal dari Pusat Penelitian Kelapa Sawit (PPKS), Medan,  sedangkan inokulum CMA diproduksi menggunakan kultur pot. Enam perlakuan yang diuji merupakan kombinasi tiga jenis inokulasi CMA ( tanpa inokulasi, inokulasi dengan Acaulospora tuberculata dan Gigaspora margarita) serta dua tingkat pemupukan (tanpa, dan dengan pemupukan). Hasil yang diperoleh menunjukkan bahwa inokulasi CMA merubah sistem morfologi dan arsitektur perakaran. Bobot basah, bobot kering, panjang dan volume akar nyata lebih tinggi pada tanaman yang dikolonisasi CMA khususnya A. tuberculata. Namun berat akar spesifik tidak beda nyata antara yang diinokulasi dan tanpa inokulasi. Peningkatan berat akar sangat nyata setelah 26 hari diinokulasi. Di samping itu proporsi akar sekunder lebih tinggi dibandingkan dengan akar primer pada  tanaman kelapa sawit yang diinokulasi CMA. Pemupukan pada umumnya menurunkan pertumbuhan akar dan secara nyata menurunkan nisbah akar pucuk. Volume perakaran lebih besar pada bibit kelapa sawit yang diinokulasi dibandingkan dengan yang tidak diinokulasi.  Peningkatan serapan  N, P,  dan  K tertinggi teramati 26 minggu setelah inokulasi. Morfologi perakaran yang lebih baik demikian pula arsitektur perakaran mungkin merupakan mekanisme bibit kelapa sawit bermikoriza dalam meningkatkan serapan P.

Inceptisol is a young and newly developed soil so it needs to be optimized for crop cultivation. The aim of this research is to know the availability of soil P, P uptake and corn yield after application of granular composting of sago waste (KGES) together with phosphate fertilizer to Inceptisols soil. The experimental treatment was KGES which consisted of three levels: without KGES, 40 tons KGES ha-1, and 80 tons KGES ha-1, and the use of SP-36 (P) fertilizer consisting of three levels: without P fertilizer, 120 kg P ha-1, and 240 kg P ha-1. The experiment used a complete randomized design with 3 replications. The result of the experiment was analyzed variance and relationship test using interlaced analysis. The results showed that KGES together with phosphate fertilizers could increase soil pH causing phosphate to be available and plant roots could absorb nutrient phosphate well, so that the yield of corn kiln dry weight also increased. The highest yield of dry weight of grains (7.85 tons per ha) was obtained from a combination of 80 tons of KGES ha-1 and 240 kg P ha-1.Keyword: Keywords: Ella Sago, Inseptisols, maize, phosphate

Phosphorus (P) is an element that is potatoes require in large amounts. Soil pH is a crucial factor impacting phosphorus availability in potato production. This study was conducted to evaluate the influence of P application rates on the P efficiency for tuber yield, specific gravity, and P uptake. Additionally, the relationship between soil pH and total potato tuber yield was determined. Six rates of P fertilization (0–280 kg P ha−1) were applied at twelve different sites across Northern Maine. Yield parameters were not responsive to P application rates. However, regression analysis showed that soil pH was significantly correlated with total potato tuber yield(R2 = 0.38). Sites with soil pH values < 6 had total tuber yields, marketable tuber yields, tuber numbers per plant, and total tuber mean weights that were all higher than these same parameters at sites with soil pH ≥ 6. All sites with soil pH< 6 showed a highly correlated relationship between P uptake and petiole dry weight (R2 = 0.76). The P application rate of 56 kg P ha−1 was the best at sites with a soil pH < 6, but 0–56 kg P ha−1 was the best at sites with soil pH ≥ 6.

Rehabilitation of post-mining limestone soils is often a challenge due to a lack of nutrients and poor soil humus. The research aims to study the effect of various ameliorants on soil chemical properties, growth, and P uptake of gaharu plant (Aquilaria malaccensis) in post-mining limestone soil for revegetation of critical land. The research was conducted in a Completely Randomized Design with three replications. The treatments were P0 (Control, without ameliorant); P1 (Humic Acid, HA, 4 kg ha-1 ); P2 (Phosphate Rocks, PR, 350 kg ha-1 ); P3 (Vesicular Arbuscular Mycorrhizal Fungi, AMF, 500 spores plant-1 ); P4 (HA+AMF); P5 (PR+AMF); and P6 (HA+PR+AMF). Data were analyzed using ANOVA at 95% confidence level and continued with the LSD test. The use of various types of ameliorants (HA, RP, and AMF) significantly increased root length, root volume, wet and dry weight of roots, shoot wet and dry weight, and P uptake of gaharu tree. The best ameliorant in increasing gaharu tree growth was AMF (P3) treatment, and AMF combined with HA (P4) treatment. Thus, for revegetation of critical land, especially post-mining limestone land, using gaharu tree requires HA and AMF inoculation.

<p>This research aimed to evaluate the effect of empty fruit bunches (efb) compost, phosphate-solubilizing bacteria (PSB), lime, and types of P fertilizer on the growth and availability of Phosphorus and P uptake in the pre-nursery (PN) oil palm seedlings in latosols. The pot experiments were arranged in a Factorial Completely Randomized method. The first factor was the application of efb compost: without efb compost, efb compost, without efb compost + PSB, and without efb compost + lime. The second factor was the types of P fertilizer: SP-36, RP, guano, and NPKMg + Urea as a control. The results showed that the combination of without efb compost +lime and RP fertilizer produces the highest number of leaves. The influence of a single factor showed that the application of without efb, efb compost, without efb compost +PSB, without efb compost + lime, resulted in the same growth of seedlings, except on plant height and the length of the leaf. The various types of P fertilizer led to the same growth of seedlings except for stem diameter. The highest available P was obtained in the combination of without efb compost + PSB with SP-36 fertilizer, which was 631.1% compared to control (without efb compost and NPKMg, Urea) and the lowest in the combination of without efb compost + lime with (NPKMg, Urea). The treatment without efb compost + lime with SP-36 fertilizer increased P uptake of leaves by 55.6% and stem by 47.1% compared to control.</p>
