Abstract

The Influence of Various Kinds of Herbicide Applicated at Different Dosages and Times on Soybean Seed Quality in Rainy SeasonABSTRACT. The experiment was carried out to study the influence of various kinds of herbicide at different dosages and times on soybean seed quality in rainy season. The experimental was conducted at PT Syngenta, Cikampek, West Java. This experimental was arranged in the split-split plot based of randomized block design with 2 replications. The main plot was the time application consists of: R6, R7, and R8 phase. The sub-plot was the application doses of the herbicide that consists of: no herbicide, lower dosage, medium dosage, and higher dose. The response observed covers the seed’s water content at harvesting, seed’s viability, seed’s vigor, the percentage of winkle seed, the weight of 100 seeds and the yield per plot. The result shows that the application of paraquat at lower dose and at R7 nd R8 phase yielding the highest quality compared to any other treatment.

Abstract

The Competitive of Soybean Used as Dessicant with Paraquat and Glifosat Herbicide on Stress of WeedsABSTRACT. Herbicide might be use for desicant to increase soybean seed quality at rainy season, however not all herbicide can be used as dessicant. Seed with a better quality will growth faster than weed will, they will form leafy coronet that shaded the weed and be able to compete against to the weed. The experiment was conducted during rainy season at PT Syngeta-Cikampek, West Java, started from November 2003 to March 2004. This experiment that was the second experiment was arranged in two-factor randomized block design with two replications. The first factor was the 21 seeds generated from dessicacy test in experiment 1; the second factor was the invasion status of weed that consist of weed invated and weed free. The observed responses includes the weed’s characteristics that consist of dominant value ratio and the soybean’s response that consist of the height of the plant, the length of the root, the weight of 100 seed. The data was analyzed by Percentage Change Test, Least Significant Increase (LSI) Test, Stres Tolerant Index (STI) Test and continued by Directed STI, The result shows that the seed generated from paraquat herbicide dessicacy at dose of 0.4 kg a.a ha-1 applicated at R2 are more superior than other seed treated by any oyher treatment.
