Abstract

b-cyfluthrin has been in agricultural use in the recent years for controlling Lepidopteran pest affecting leafy vegetables crops. The extensive use of synthetic pyrethroids like b-cyfluthrin has resulted in wide spread environmental contamination. A study on residue dynamic of b-cyfluthrin applied to kangkong-land has been conducted. Buldock 25 EC with maximum recommended dose was used. The analysis was performed on kangkong land while land without kangkong used as control. Extraction was carried out with the soxhlet method, while the cleaning up process was carried out with carbon-and-florisil-double-layered column. High resolution gas chromatography with Electron Capture Detector (ECD) was used to determine the concentration. On  kangkong-land with 14,52% organic matter, sorption of b-cyfluthrin was observed. Residue of b-cyfluhtrin on soil increased to 16th days. The dissipation rate on land without kangkong and kangkong-land are fast with dissipation rate 2,5 x 10-1 day-1  and 5,76 x10-1 day-1respectively. Organic matter play an important role in the dissipation rate of b-cyfluthrin residue in the tropical farmland of Indonesia.

Abstract

The study was aimed at determining appropriate varieties and growing media on growth and yield of red peppers as well as interactions between the two factors mentioned. The experimental design used was a completely randomized design (CRD) 3 x 3 with three replications. Factors studied were red pepper varieties (TM 999, ST 168 and local), and growing media (soil + sand, soil + manure, and soil + husk) with a ratio of 2:1. The results showed that varieties exerted highly significant effects on plant height at 15 days after transplanting (DAT) and fruit weight per plant at first harvest 90 DAT and a significant effect on number of fruits per plant at first harvest 90 DAT. Varieties of TM 999 and ST 168 were better than that of local. Growing media also exerted highly significant effects on plant height at 45 DAT, number of productive branches, number of fruits per plant at first harvest (90 DAT) and fruit weight per plant at first harvest (90 DAT), and significant effects on plant height at 15 and 30 DAT, number of fruits per plant at second harvest (93 DAT), and weight of fruit per plant at third harvest (96 DAT). The best growing medium was soil + sand. There was no significant interaction between varieties and growing media on growth and yield of red chili.

Abstract

ABSTRACT A research on behavior of pest S. litura on two varieties of soybean has been done in Blang Manyak Village, Sawang Sub district, North Aceh District from January–May 2013. The research was arranged in a field experiment with two treatments of soybean varieties, that is Kipas Merah and Anjasmoro.  Each treatment was repeated 20 times to obtain 40 units of the experiment. Variables measured included damage intensity of S. litura, trichome density of leaves, yield components, and resistance evaluation. The relationships between yield components and damage intensity of S. litura were analyzed with regression and correlation. The results showed that damage intensity of S. litura on Kipas Merah was lower than that on Anjasmoro. Loss of soybean yield components on both varieties was influenced by the damage intensity of S. litura. There was a negative correlation between damage intensity of S. litura and soybean yield components on both varieties.  Kipas Merah was moderately resistant and Anjasmoro was susceptible against S. litura.  Resistance differences of both varieties were influenced by trichomes density of the leaves.

Abstract

Problems that arise in forage supply are continuity of farm and it’s low productivity and limited soil water availability in dry season. This study aims to: 1) examine the role of AMF on the growth of some types of grass fodder by different levels of water stress on podzolic soil; and 2) understand the interaction between application of AMF in different water stress and the types of grass on growth of forage grasses. This research was conducted in plastic house of Field Laboratory of Assessment Institute for Agricultural Technology (BPTP) Aceh. Randomized block design (RAK) with 6 x 3 factorial for three replications was used. The first factor was application the AMF and water stress which consists of six levels, namely: C1 = Without AMF + water stress 60% of field capacity, C2 = Without AMF + water stress 80% of field capacity, C3 = Without AMF + without water stress (100 % of field capacity), C4 = AMF + water stress 60% of field capacity, C5 = AMF + water stress 80% of field capacity, C6 = AMF + without water stress (100% field capacity). The second factor was type of grass that consists of three levels, namely: R1 = Brachiaria decumbens, R2 = Brachiaria mutica, R3 = Cynodon plectostachyus. The parameters observed in this research were canopy fresh weight, root dry weight, leaf relative water content. Results showed AMF addition of water stress 60% of field capacity on Jantho podzolic soil increased the canopy fresh weight, root dry weight, and leaf relative water content. There were interaction effects between applications AMF at different water stresses and the types of grass against canopy fresh weight, root dry weight and leaf relative water content.

Abstract

            The study on application of different dosages of paraquat herbicide on different ages of milkyweed (Calotropis gigantea R. Br) have been conducted in Experimental Station, Agriculture Faculty, Syiah Kuala University, Darussalam Banda Aceh. The treatments were arranged in a Completely Randomized Design (CDR) with two factors. The first factor was dosages of herbicide which were 0; 0,1; 0,2; 0,3; and 0,4 kg active ingredient (a.i.) ha-1. The second factor was ages of  C. gigantea R. Br which were 30 days, 45 days and 60 days after planting. The result showed that dosage of 0,3 kg i.a. ha-1 significantly increased the percentage of C. gigantea R. Br and decreased the dry weight shoot and root of C. gigantea R. Br. The youngest stage of C. gigantea R. Br was more effective to be controlled, and had a lower dry weight shoot and root than the oldest one. The paraquat herbicides applied with dosages of 0,3 kg a.i. ha-1 on 30 days after planting increased the percentage of C. gigantea R. Br, and  reduced shoot and root dry weight of C. gigantea R. Br.
