The potential of agriculture in Indonesia has not been fully explored. favorable climatic conditions, natural resources, and human resources. West Nusa Tenggara (NTB) an unproductive land area 1.807.463 ha the total NTB. One efforts to increase productivity dry is application biological fertilizer. Biofertilizers that are expected have a high contribution increasing fertilization efficiency Ves...

Abstrak: Penyakit busuk pangkal batang yang disebabkan oleh patogen Sclerotium rolfsii merupakan penyakit penting dapat menurunkan produksi kacang tanah. Salah satu upaya pengendalian yaitu menggunakan Mikoriza arbuskula dan Trichoderma hatzianum. T. harzianum cendawan ramah lingkungan mampu sebagai pelindung akar, meningkatkan ketahanan pertumbuhan tanaman. Peubah diamati meliputi tinggi tanam...

the effects of arbuscular mycorrhizae on water use efficiency and some growth characteristics of maize were studied at three water regimes. an farm experiment was carried out using a split plot based randomized complete block design with 3 replications. main plot was under water deficit condition (100%fc, 66%fc, 33%fc) and sub plot included application of two species of mycorrhizae, m1:glomus m...

An efficient regeneration system was developed for Kigelia pinnata L., a multipurpose tree belonging to the family Bignoniaceae. The nodal segments were cultured in vitro, and the optimum concentrations of plant growth regulators for callus induction were determined. The friable organogenic calli were derived from the basal cut end of the nodal segments. The highest yield of morphogenic callus ...

In a first experiment of soil contaminated with 137Cs, inoculation with a mixture of arbuscular mycorrhizae enhanced the uptake of 137Cs by leek under greenhouse conditions, while no effect on the uptake by ryegrass was observed. The mycorrhizal infection frequency in leek was independent of whether the 137Cs-contaminated soil was inoculated with mycorrhizal spores or not. The lack of mycorrhiz...

Arbuscular mycorrhizae are important for growth and survival of tropical trees. We studied the community of arbuscular mycorrhizal fungi in a tropical mountain rain forest and in neighbouring reforestation plots in the area of Reserva Biológica San Francisco (South Ecuador). The arbuscular mycorrhizal fungi were analysed with molecular methods sequencing part of the 18 S rDNA. The sequences wer...

The symbiotic association between certain plants and microorganisms plays an important role in soil fertilization, and improves their growth and mineral nutrition. Microorganisms implicated in this symbiotic interaction are from two groups: bacteria and fungi. The bacteria group is implicated on nitrogen fixation (for review see Pawlowski and Bisseling, 1996), while the fungal group is involved...

Accepted : June, 2009 Mango is one of the most popular fruit crops grown in tropical and subtropical countries. It is considered as ‘National fruit of India’ and is rightly called as ‘king of fruits’ due to unique taste, flavour and is popular within all sections of society. Mango is cultivated vegetatively by adopting several techniques like inarching, budding, stone grafting but veneer grafti...

Eight hardwood species were grown in fumigated soil without vesicular-arbuscular mycorrhizae (VAM) or in soil infested with a mixture of Glomus mosseae and Glomus etunicatus. Three fertilizer treatments of 140, 560, and 1,120 kg/ha of 10-10-10 fertilizer were established in combination with the two mycorrhizal treatments. Ten equal applications of NH4NO3, totaling 1,680 kg/ha, were added to all...

Photosynthate partitioning was examined in seedings of sour orange (Citrus aurantium L.) and Carrizo citrange (Poncirus trifoliata [L.] Raf. x C. sinensis [L.] Osbeck) grown with split root systems inoculated on one side with vesicular-arbuscular mycorrhizal fungus (Glomus intraradices Schenck and Smith). Source-sink relations were studied without mitigating differences in mineral content or ph...
