Abstract

This research conducted in research farm, Faculty of Agriculture, Ciparanje, Jatinangor from October 2014 to January 2015. This research aimed to verify the competition ability on plant growth of soybean varieties due to the presence of weeds with weeding frequency. The experiment was arranged in factorial randomized block design with three replications. The first factor was soybean variety and the second factor was weed competition period. The result of this research showed that seed size from each variety of observation time 4 WAP (weeks after planting) to 10 WAP not significantly different. Each treatment on weed control in 4 WAP also not significantly different. Next observation (6, 8 and 10 WAP) showed that there were significant differences in competition point. Observation in 6 WAP showed that G6 was bigger than G5. It means that soybean was able competed with weed. Treatment G7 and G8 were higher because right time control period of weed was the best time as a plant critical period where plant was sensitive to competition getting the necessary growth factors for plant growth and yield.

Abstract

This study aims to examine the effect of concentration of liquid organic fertilizer supermes on various spacing to the growth and yield of onion. The experiment was conducted in Dusun Telaga Kodok, Hitu Lama Village, Leihitu Barat District, Central Maluku District, from March to April 2017. The experiment used was a Randomized Block Design with three replications. The concentration of liquid organic fertilizer supermes consists of: 0, 2, 4, 6 mL/L water. Plant ing distance consists of: 10 × 15 cm, 15 × 15 cm and 20 × 15 cm. Varieties used were varieties of Bima Brebes. Parameters measured were plant height, number of leaves, number of tubers, root length, wet weight and dry weight of tubers. During the experiment, rainfall and rainy days were quite high at the research location. This condition causes the crop to be harvested at 41 HST because it is attacked by ground caterpillar, mosaic disease and purple spots. The application of liquid organic fertilizer has not shown any significant effect to the growth and yield parameters of shallot crop. Planting distance of 15 × 15 cm shows the effect on plant height and number of leaves at 35 HST, tuber weight and tuber dry weight and there is a significant interaction on the leaf number at 35 HST with concentration of 4 mL/L water and Planting Distance 15 × 15 cm. Keywords: liquid organic fertilizer, planting distance, red onion ABSTRAK Penelitian ini bertujuan untuk menguji pengaruh konsentrasi pupuk organik cair supermes pada berbagai jarak tanam terhadap pertumbuhan dan hasil bawang merah.

Abstract

The presence of weeds in crop cultivation has a negative effect on the crop because of their high competitiveness. One of the roles of weeds as allelopathy because weeds release chemical compounds that can inhibit growth and kill plants around them. This study aimed to determine the effect of concentration of ‘bandotan’ plant extracts plants at various application times on the growth and yield of mustard. The research was carried out at the Greenhouse of the Faculty of Agriculture, Pattimura University, from November 2017 to January 2018. This study used an experimental method with a completely randomized design (CRD) involving two factors and with three replications. The first factor was ‘bandotan’ extract with 4 concentration levels: control (no extract), 100 g/L, 200 g/L and 300 g/L. The second factor was application time with three levels: 5 days after planting (DAP), 10 DAP, and 15 DAP. The variables observed included plant height, leaf number, leaf area, fresh crop weight, and crop dry weight. Data analysis of each variable was conducted using the analysis of variance. If there was a significant treatment effect, it proceeded with the Tukey test at the level of α = 0.05. The results showed that the concentration of ‘bandotan’ extract did not significantly affect all observation variables (plant height, leaf number, leaf area, fresh crop weight, and dry weight of mustard). Time of ‘bandotan’ extract application did not significantly affect all observation variables (plant height, leaf number, leaf area, fresh crop weight, and dry weight of mustard). The interaction between ‘bandotan’ extract concentration and application time did not significantly affect all observed variables. Keywords: application time, ‘bandotan’ extract, green mustard, growth and yield ABSTRAK Keberadaaan gulma pada tanaman budidaya berpengaruh negatif pada tanaman itu karena daya kompetitif yang tinggi.

Abstract

Coconut is one of the plantation crops that has experienced a decrease in production in the village of Suli, Central Maluku Regency. One of the causes of the reduction of coconut production in each planting area in Suli Village, Central Maluku Regency, is weeds. The drastic decline in coconut production from year to year in Suli village is due to weeds, so it is necessary to know the dominant weed species in the coconut plantation area in Suli village, Central Maluku Regency. The hypothesis put forward in this study is that weeds are prevalent in the coconut planting area. This study uses the "vegetation survey" method to collect data with field observations. In carrying out the vegetation analysis, the quadratic form was used with a sample plot measuring 1 m x 1 m on six coconut trees. For each coconut tree, three weed samples were taken under the coconut canopy, so a total of 18 weed samples were taken from under the coconut canopy. Qualitative and quantitative data were taken. The data needed in this study consists of primary data and secondary data. The dominant weed in the coconut plantation area in Suli Village, Central Maluku Regency, is the broadleaf weed Melastoma malabathricum L.

Abstract

Weeds are plants whose presence is unwanted because they interfere with and reduce the yield of cultivated plants. One of the plantation crops with high economic value is coconut. Coconut is a commodity that can make a major contribution to the economy in Indonesia. The presence of weeds in coconut plantations will reduce yields. This study aims to determine the diversity and dominance of weed species that grow in the coconut plantation area in Tial Village, Central Maluku Regency. This study uses the "weed survey" method to collect data by direct observation in the field. In conducting vegetation analysis, the quadratic method was used with a sample plot measuring 1 m x 1 m. For sampling in the coconut planting area in Tial Country, 6 plant samples were taken at each plant stage to obtain 12 plant samples and repeated 3 times to obtain 36 observation samples. Observations of weeds in Tial Village showed that in the immature coconut planting area, there were 11 broadleaf weed species from 10 broadleaf weed families, 3 pakisan weed species from 2 pakisan weed families and 1 grassy weed species from the Poaceae and 1 type of tekian weed from the Cypeaceae tribe, as well as from observations of weeds in Tial Village, it shows that in the coconut plantation area at the productive stage, there are 13 types of broadleaf weeds from 11 broadleaf weed families, 2 types of pakisan weeds from 1 pakisan weed tribe and 1 type of grass weed from the Poaceae tribe and 1 type of tekian weed from the Cypeaceae tribe. Based on the total dominant value Summed Domination Ratio (SDR) the immature plant had the highest value, Thuja occidentalis 26.78 percent from the Convovulaceae tribe. In the coconut planting area the mature stage of the plant having the highest SDR value was Stelaria holasta.L 29.21 percent from the Caryophylaceae.
