Abstract

Mycorrhizal symbiosis increases nutrient uptake for plants, resistance to disease, stabilizes soil aggregates and promotes the growth of soil organisms. Fungal hyphae containing glomalin is essential for soil biological processes because of their interactions with plants, soils, and microbes. Activity of AMF in the area of rhizosphere and mycorizosphere will improve the physical, chemical and biological conditions of the soil, thereby providing a healthy soil environment for plants. How the influence of AMF inoculants plus organic ingredients on growth and production of maize on Ultisol needs to be tested in the field.  The purpose of this experiment is the application of AMF plus organic inoculants to corn planting, to determine the effect on growth and increase of corn production. Experiments using a randomized block design with four groups. The AMF inoculation treatment was the administration of organic plus inoculant from G. luteum (F1), G. verruculosum (F2), G. versiforme (F3), Multi species of AMF (F4) and without AMF inoculation (F0). The results showed that AMF inoculation had significant effect on total glomalin. G. versiforme has the highest total glomalin, which is 10.59 mg.g-1. The effect of AMF species had no significant effect on aggregate stability, but was significantly different from the treatment without AMF inoculation. The effect of AMF on N, P and K uptake is significantly different. The highest dry corn kiln production from G. versiforme, which is 8.07 kg / plot or 4.04 ton / ha, has the same effect as G. luteum (7.98 kg / plot or 3.99 ton / ha) and Multi AMF (7.67 kg / plot or 3.84 tons / ha). Increased production of dried corn plants inoculated with AMF plus organics can reach 40-83% higher than the plants without giving the AMF.Key words : mycorizosphere, productivity, rhizosphere, Ultisol

Abstract

To look for the effect of gold snail (Pomacea canaliculata) addition on soil nutrition level, a series of pot experiment was conducted in Faculty of Agriculture and P3IN laboratories from March to June 2008. This study used completely randomized design with 2 kinds of treatments. First iwas gold snail composition (A1 = snail shell, A2 = snail body, and A3 = whole snail) and incubation period (B1 = 2 weeks, B2 = 3 weeks, and B3 = 4 weeks). The results showed that these treatments affect some of soil chemical properties. Soil pH changed from acid to slightly acid, total nitrogen rose from low to medium, exchangeable base cations also increased. On the other hand, exchangeable aluminum (Al) decreased. Interaction between the treatments successfully increased organic carbon, available phosphorous, and cation exchange capacity. The best treatment combination was between body composition of gold snail and a four-week incubation period.Key Words: gold snail, Ultisols, soil chemical characteristics

Abstract

Banana is one of fruit commodity having been widely cultivated by people and has high potency for agribusiness.  However, there are some constraints for the cultivation, such as soil fertility and disease attack.  Nowadays, tne main disease causing low banana production in West Sumatra is wilt due to Fusarium.  One way being developed to improve banana production in endemic land is by using bioagent.  This research was aimed to identify spores of mycorrizhae in several endemic land.  The result showed that there were various types of MVA found in tested locations (Agam, Solok, and Padang Pariaman regencies).  Glomus was one genus that was always found in each location.  Therefore, the glomus sp was quite potential to explore and and proliferation as a good innoculant to improve growth of banana plant.  The highest amount of MVA sport found in Padang Pariaman regency (especially in Pasar Usang area) was 195/20 g soil (Glomus), then followed by Acaulospora (121 spora/20 g soil) and Gigaspora (65 spora/20 g soil).Key Words: Banana, Fusarium, Wilt, Bioagent, MVA
