Abstract

The objective of this study was to evaluate the herbicide effectiveness of IPA-Glyphosate (480 g/l) in control the common weeds on immature oil palm plantation. This study was performed in oil palm plantation at Rasau Jaya, Kubu Raya Regency, Kalimantan Barat Province. Vegetation analysis was conducted by using the square methods. Herbicide application carried out by a spraying method. Experiment arranged by randomized block design with 6 treatments and 4 replications. The results showed at 12 weeks after application the average density of weeds covering is 2,4-40%. The IPA- Glyphosate herbicide (480 g/l) with dose 5 l/ha effective suppressed the growth kinds of weeds up to 12 weeks after application and didn’t cause phytotoxicity in oil palm plantation.

Abstract

This study aims to determine the effect of tillage on the amount of deposits of weed seeds in the soil on alluvial soil. Research conducted at the Faculty of Agriculture experimental field Tanjungpura in August to December 2014. Identification and data processing carried out at the Laboratory of Plant Pests Tanjungpura University . Research using observation method with weeds growing vegetation analysis after tillage. Observations were made after 1 times tillage , 2 times , 3 times and 4 times. Results of this study indicate that there are five species of weeds that have the highest amount of seed bank with a value of SDR above 10 % and is considered an important weed that is, Borreria alata, Cyrtococcum sp, Ageratum conyzoides, Ludwigia parennis and Phyllantus debilis. Based on the results of this study concluded that as many as 1 times tillage can reduce the weed seed bank  in the soil deposits if done before the weeds produce seeds.
