Abstract

A rapid survey was carried out to study the quality of corn produced by farmers in relation to post harvest practices in West Pasaman district. Twenty-six corn farmers, which were located in two sub districts of Kinali and Luhak Nan Duo, were selected and interviewed. Data and information collected including: farm size, farming and post harvest practices, quality of product and marketing. During the survey, samples of corn were collected and then analyzed for moisture, protein and crude fiber content, the rate of corn contaminated by fungi and contaminants. The corn contained crude protein and fiber in normal level of 11.8 % and 2,5 %, respectively. The moisture content was however found relatively high of 21.3 % in average and about 34 % of corn contaminated by fungi. Mainly insufficient handling and drying after harvesting caused the poor quality.

Abstract

n order to analyze and to study expressions of the Al-tolerant genes, we have examined five clone genes that were isolated from soybean cv. Lumut. Soybean cv. Lumut and Slamet, Centrocema pubescens, Pennisetum purpureum and Escherichia coli were selected for futher analysis. Based on the DNA sequencing, searching enzyme restriction sites and searching DNA homology with the genebank database; the clones encoding: (1) Catalase (gmali12, that function as an antioxidant), (2) Proliferating cell nuclear antigen like protein/PCNALP (gmali15, that involved as one of transcriptional regulator in the eucaryotic cell cycle), (3) Growth hormone (gmali22, this gene may play a role on stimulation of cell growth/development), (4) Amine oxidase (gmAO, genebank accession number AF313622, a gene that function as amine oxidation and/or antioxidant), and (5) Aminoacyl peptidase (gmAP, genebank accession number AF091304, a serine protease gene). Expressions of the clone genes either on forage crops or Escherichia coli indicated that all of the clones are basic genes, but its expression increased with aluminium induction (Al-induced genes) and involved in detoxification to Al stress. From this research, we also found similar responses between oxidative stress and Al stress to gene responses.

Abstract

The research was conducted to evaluate growth  of alfalfa mutan (plant height increment, number of leaves and dry matter production) in different  Nitrogen Fertilizer and defoliation intensity. The design used was randomized block design 4x2 factorial with 3 replications. The first was dosage of Nitrogen fertilizerNitrogen   (0, 30, 60 and 90 kg N / ha),  the second factor was defoliation intensity (5 and 10 cm). Variables observed alfalfa growth (plant height increment, number of leaves, the production of dry matter (DM) forage). The results showed that different N fertilization did not affect the growth of alfalfa mutants. Defoliation intensity  affectedmnumber of leaves and   DM  production of alfalfa mutant. Fertilization to 90 kg N / ha has not affected the growth and   defoliation  intensity 10 cm gave better growth on alfalfa mutant.   [Keywords: alfalfa mutant; Nitrogen fertilizer; defoliation; growth]

Abstract

The experiment was conducted in Soil Fertility Laboratory, Agriculture Faculty, IPB from March to July 2009. The treatment was arranged in Factorial Completely Randomized Design with two factors i.e. insitu water source and condition of redox potential. Water source for leaching was fresh water, peat water, and brackish water. The condition of redox potential consisted of: -100 ± 25, 0 ± 25, 100 ± 25, 200 ± 25, 300 ± 25, and 400 ± 25 mV. In leachate water on redox potential as 400 mV, the concentration of Fe2+, total Fe, SO42-, and Al were 376.76, 554.44, 961.55, and 180 ppm respectively (at first week) decreased into 227.20, 312.22, 506.86, and 44 ppm (at eight week). Whereas in leachate water that leaching by peat water, at the first week concentration of Fe2+, total Fe, SO42-, and Al were 412.50, 493.11, 823.57, and 110.50 ppm decreased into 253.65, 302.50, 463.60, and 29.50 ppm at the eighth week. After leaching as long as eighth weeks, concentration of Fe2+, total Fe, SO42-, and Al in soil material decreased from 578.26 ppm, 3680 ppm, 1011.26 ppm, and 18.66 me 100g-1 to 350.26 ppm, 3095 ppm, 376.76 ppm, and 11.79 me 100g-1.
