Arbuscular mycorrhizal fungi (AMF) can help plant to uptake of low P availability in acid soils because of the ability of AMF to adapt from acid soil. Humic acid plays a role in adsorption metals such as Al. The purpose of this research was to study the effect of addition of AMF and humic acid to acid soils on growth, yield and quality of grass. A complete randomized design with factorial pattern was applied to two types of grasses, namely: Setaria splendida (Al-tolerance) and Chloris gayana (Al-sensitive). The first factor is the addition of AMF, which consists of two levels, namely: -AMF = without AMF. +AMF = with AMF. The second factor was the addition of humic acid which consists of four levels, namely: Ho = without humic acid, H60 = 60 ppm humic acid usage, H120 = 120 ppm humic acid usage and H180 = 180 ppm humic acid usage. Variables measured were dry matter production of shoot and roots, uptake of P and N, the production of phosphatase, root infection, the number of spores. AMF and humic acid augmentation on Setaria splendida did not affect on growth and production, but they improved the uptake of P and N total. AMF augmentation enhanced growth, yield and quality of the Chloris gayana. The use of 180 ppm of humic acid could improve the quality of Setaria splendida and Chloris gayana.

Mekanisme toleransi tanaman terhadap toksisitas aluminium (Al) dapat dipelajari melalui perbandingan toleransiantara tanaman toleran dan tanaman sensitif toksisitas Al. Setaria splendida adalah tanaman pakan yang toleran terhadapAl, sedangkan Chloris gayana merupakan tanaman yang sensitif. Penelitian ini dilakukan untuk mengungkapkan mekanismetoleransi S. splendida terhadap toksisitas Al. Percobaan pertama disusun menggunakan rancangan acak lengkap yang terdiriatas dua faktor untuk mempelajari akumulasi Al dan asam organik pada S. splendida dan C. gayana. Faktor pertama adalahkonsentrasi Al (0 dan 2 mM Al), sedangkan faktor kedua adalah jenis rumput pakan, yaitu rumput toleran Al (S. splendida)dan rumput sensitif Al (C. gayana). Percobaan kedua disusun menggunakan rancangan acak lengkap yang terdiri atas duafaktor dan tiga ulangan untuk mempelajari pengaruh cekaman Al pada S. splendida dan C. gayana. Faktor pertama adalahjenis rumput pakan (S. splendida dan C. gayana), sedangkan faktor kedua adalah konsentrasi Al pada media tanam (28.19,27.37, 13.74, and 0.13 me Al3+). Hasil penelitian ini menunjukkan bahwa akumulasi Al pada jaringan akar S. splendida tidakberbeda dengan yang terakumulasi pada jaringan akar C. gayana. Walaupun S. splendida mengakumulasikan Al dalamjumlah yang lebih tinggi dibandingkan C. gayana di bagian tajuk, S. splendida memiliki toleransi terhadap toksisitas Al.Toleransi S. splendida terhadap toksisitas Al dicapai dengan cara mensekresikan asam oksalat dan asam sitrat dari akar kelarutan eksternal, dan mengakumulasikan asam asam oksalat dan asam malat pada akar dan tajuk.Kata kunci: aluminium, asam organik, Chloris gayana, Setaria splendida, toleransi

The objective of the study was to explore the appropriate cutting age to produce optimal biomass and good nutrient quality from sorghum mutant lines BMR i.e., PATIR 3.5 M7, PATIR 3.6 M7, and PATIR 3.7 M7, also SAMURAI I (M17). A completely randomized in Split Plot design with 2 factors and 3 replicates was used. The first factor was the type of sorghum (SAMURAI I M17, PATIR 3.5, PATIR 3.6, PATIR 3.7) as the main plot and the second factor was the cutting age (85, 95, 105) as a subplot. Parameters observed were the production of stems, leaves, grains, total biomass production, ash, crude fat, crude fiber, crude protein, NFE, TDN, percentage of DMD, OMD and N-NH3. Data were analyzed by using ANOVA followed by DMRT (Duncan Multiple Range Test). The results showed that there were highly significant interactions (P<0.01) between cutting age and type of sorghum in production of stems, leaves, grains, total biomass production, value of TDN, DMD, OMD, and N-NH3. Increasing cutting age significantly increased the percentage of ash content, crude protein and crude fat. The sorghum type significantly affected crude fat content nonBMR sorghum variety of SAMURAI I (M17) and achieved optimal biomass production and nutrient content at cutting age of 85 d similar to BMR sorghum mutant lines PATIR 3.6 and PATIR 3.5, whereas BMR sorghum mutant lines of PATIR 3.7 achieved optimum production at the age of 95 d of cutting. All types of sorghum varieties was not recommended to be harvested at 105 d. Biomass production increased with the increasing of cutting age, but the nutrient content decreased.Key words: cutting age, mutant, sorghum

Acclimatization is the final stage of plant propagation in tissue culture techniques that can determine the success of the nursery process. This study aimed to observe the growth response during the acclimatization stage of the acid-adapted of Leucaena leucocephala Tarramba variety, which developed from tissue culture techniques. The design used in this study was a completely randomized design (CRD) with the cultivation of 11 mutant lines from tissue culture, namely M1-M11 (an acid-adapted mutant from tissue culture addition of 1 ppm IBA) and 2 controls (lamtoro broodstock without gamma irradiation) namely K0 (lamtoro broodstock resulting from tissue culture addition of 0 ppm IBA), K1 (breeding lamtoro from tissue culture addition of 1 ppm IBA). The variables observed were the level of plant viability, plant height, and number of leaves. The results showed that the acclimatization of the plant Leucaena leucocephala to tissue culture production on the M3 and M9 mutant lines gave the best response to plant morphological growth up to 5 WAP (weeks after planting). Key words: acclimatization, IBA hormone, Leucaena leucocephala, tissue culture

Sorghum bicolor var. Samurai 2 can be used as raw material in silage production for ruminant feed. The problem encountered is the difficulty of obtaining certified seeds for commercial sorghum production. So that is necessary to do this research to investigate potential sorghum seed production and its quality of Sorghum bicolor var. Samurai 2. The study was conducted at University Research Station-Jonggol Animal Education and Research Unit, Bogor Agricultural University. The experimental design used was a randomized block design with 4 treatments and 5 replicates. Five individual plants were taken to measure the variables at each treatment set. The treatments consisted of different harvesting times, namely P95 (harvested 95 days after planting), P100, P105 and P110. The variables observed were dry weight of shelled seeds, seed weight per panicle, weight of panicle stalk, panicle weight, seed production per ha, seed moisture content, seed viability test, and shoot biomass production per ha. The results showed that seed production per ha, panicle dry matter weight, fresh seed moisture content, panicle stalk dry weight was not significantly different. Dry weight of shelled seeds, dry weight of seeds per panicle, panicle dry weight, seed viability, weight of biomass per ha were significantly different (p<0.05). The potential for the production of shelled seeds, dry matter of seeds per panicle was the best in the P105 and P110, the viability of the seeds in the P105 and shoot biomass production per ha in the P105. The potential for shelled seed production (4038 kg ha-1), seed dry weight per panicle (54.87 g panicle-1), seed viability (92.8%) and the best biomass production (55.88 tons ha-1) were in treatment P105. Key words: seed production, shoot biomass, Sorghum bicolor, viability
