Abstract

Arbsucular mycorrhizal fungi promote plant growth by enhancing mineral uptake. Contribution degree of arbuscular mycorrhizal fungi to promote plant growth depend on species of plant-fungus association. The aim of this study was to compare the ability of three species of Glomus to promote maize plant growth. Maize plants were inoculated with 20 g inoculum of either Glomus deserticola, Glomus etunicatum, or Glomus clorum. Inoculum was soil containing spore, hyphae and infected root. Maize plants without addition inoculum were also used as a control. Water availability in the soil as growing medium was maintained on 40% field capacity. The results showed that addition of inoculum from three species of Glomus increased average of maize plant shoot dry weight although there was no statisticaly significant differences. Maize plant inoculated with G. clorum had higher shoot dry weight than maize plant inoculated either with G. etunicatum or G. deserticola while root colonization by G. clorum was lowest.

Abstract

Hyptis capitata Jacq. plant has been using for traditional medicine. Utilization of medicinal plant must always consider to given dose because of toxic effect when too much medicine is taken. The aim of this study was to measure the liver damage in rats caused by H. capitata Jacq. leave extract. Either 300 (P1), 600 (P2) or 900 (P3) µg/kgBW H. capitata Jacq. leave extract was given orally to rats every 24 hours during 14 days. Zero point five ml ethanol 96% was given daily (K-) and without given anything (K+) was also conducted as a control. Both macroscopic and microscopic of liver damage were assessed. The result showed that rats given P3 treatment had the highest liver damage. The liver damage in rats was not statistically significant difference between P3 and K- treatments. The lowest liver damage was in rats given K+ treatment. There was no significant difference between P1 and P2 treatments on rats liver damage. Utilization of medicinal plant as traditional medicine should always be consider to doses.

Abstract

Weeds such as Cyperus rotundus L. dan Ageratum conyzoides L. release allelopatic compounds which can inhibit the growth of crops. The aim of this study was to compare the inhibition of allelopatic compounds contained C. rotundus L. and A. conyzoides root exctract to Brassica rapa L. growth. This study was conducted in a greenhouse and was based on Completely Randomized Design with two factors. The first factor was type of root extracts (extract from either C. rotundus root or A. conyzoides root) and the second factor was concentration of root extract. Root extract concentrations added to growth medium of B. rapa L. 10 days after planting were 0, 100, 300 and 500 g/L respectifely. The addition of root extract was repeated every week until crop harvested. The results showed that there was not significantly different between C. rotundus and A. conyzoides roots extract to inhibit B. rapa growth. Increassing of root extract concentrations from both roots increased inhibition of B. rapa growth.

Abstract

Light intensity is one the most important factor to the growth of Capsicum frutescens L, however high light intensity can cause high evaporation which causes plant suffering from drought. The aim of this study was to determine the effect of different sunlight intensities and soilwater availabity to C. frutescens growth. The study was conducted by a completely randomized design method with two factors. The first factor was light entensity which consisted of 100 and 50% sunlight intensity (4287 and 2587 lux). The second factor was soil water avaibility which consisted of 75, 50 and 25% fied capacity. The results showed that plants grown at 100% light intensity had higher growth than plants grown at 50% light intensity on every soil water availability treatments. Soil water availability was not significantly affecting plant growth. It might be caused by plant received short period of sunlight.

Abstract

This study aims to know the basic media with sago pulp supplementation which can be formulated into a medium for producing white oyster mushrooms and also to know the comparison of the right media and supplements in the formulation to give maximum oyster mushrooms production. In this study using a comparison with sawdust substrate and sago pulp to see how effective the sago pulp substrate as a supplement media for the oyster mushroom production. the program used is experimental designed in Completely Randomized Design (CRD), consists of three replications so that twelve experiments were obtained. The treatment arrangement is M1: Base media without supplements (controls), M2: 90% base media + 10% sago pulp, M3: 80% basic media + 20% sago pulp, M4: base media 70% + sago pulp 30%. The observation parameters used in the study are mycelium growth, fruit body growth, biological efficiency and measurement of protein levels in the fruit body of the oyster mushroom. The results showed that the addition of sago pulp in the media of oyster mushroom production had no effect on the growth of oyster mushrooms. This can be seen from the media of production of M1 (without the addition of sago pulp) experiencing a higher growth rate of mycelium compared to other treatments. The addition of sago pulp has an effect on the levels of oyster mushroom protein. This can be seen from the protein content of oyster mushrooms in M2 production media which have high protein content. Normal levels of white oyster mushrooms in sawdust media range from 18% -20%. This is due to the mixing of wood powder as a production medium and 10% sago pulp as supplementation to produce more nutrient levels.

Abstract

Potato (Solanum tuberosum L.) is one of crops which cultivated by farmers in Central Sulawesi. These potatoes are traditionally cultivated without going through the breeding process, so they have high variations. This study aims to obtain information on genetic diversity, heritability, and correlation between the characterics of potatoes from farmers in Napu who are still cultivating potato crops. Design used in this study was a randomized block design with two replications. The results showed that tuber color and harvest age had a small coefficient of genetic diversity. The heritability values ​​of tuber color are include in the small category, Diameter of stem, number of leaves, leaf length, leaf width, leaf color, tuber length, tuber diameter, tuber weight, number of tuber and harvest age in this study are include in the high category. So that, these characteristics can be derived and selection can be made. In Napu potatoes, the number of tubers was genetically positively (medium) correlated between plant height and stem diameters, plant height with leaf width, leaf length with leaf width, leaf length with tuber diameters and tuber diameters with the number of tubers. While the positive correlation was very significant (strong) between plant height and leaf length, and very significant (strong) negative correlation between leaf color and tuber length, so can be used as a selection criteria for increasing potato crops.
