Abstract

Caterpillars are insects that eat oil palm leaves. As a herbivore, its presence and feeding activity will be affected by the growth phase of the host plant. This study aims to determine the percentage and intensity of caterpillar attacks on oil palm (Elaeis guineensis Jacq.) which have not yet produced fruit in Dharmasraya Regency. The research was carried out in July-September 2022 and the location was determined using a purposive sampling method. The research was conducted in two immature oil palm plantations (Nagari Silago and Timpeh) and two mature areas (Nagari Sitiung and Muaro polite). Determination of sample plants was carried out diagonally and taken ± 10% of the total population of palms. The caterpillars found during the research in the oil palm plantations of Dharmasraya Regency consisted of 2 species, namely Setora nitens and Setothosea asigna. At the four study locations, the average percentage of infected plants, infected midribs, and attack intensity were 43.47; 40.71; and 19.86 %. Immature oil palm plants have a higher rate of fireworm attacks than mature ones.

Abstract

This study aims to determine the quality of Sansevieria plants in absorbing carbon monoxide (CO) and to determine the relationship of stomatal conditions to the quality of carbon monoxide (CO) absorption. The research was conducted in the form of a 2-factor factorial experiment using a Randomized Group Design as the environmental design. The experiment consisted of 2 factors, the first factor was the variety of Sansevieria plants consisting of three varieties, namely Sansevieria trifasciata, Sansevieria cylindrica and Sansevieria green hahnii, while the second factor was the concentration of carbon monoxide (CO) consisting of two levels, namely: the concentration of carbon monoxide released at 300 ppm and the concentration of carbon monoxide released at 800 ppm. The results showed that there was no interaction between varieties of Sansevieria plants with carbon monoxide concentrations on the quality of carbon monoxide (CO) gas absorption. The results showed no interaction between the varieties of Sansevieria plants and carbon monoxide concentrations in terms of the quality of carbon monoxide (CO) gas absorption. Sansevieria plant varieties that are given a carbon monoxide concentration of 300 ppm give the best effect on the total percentage of carbon monoxide gas absorption, which is 89.50%.

Abstract

Sweet potato production fluctuates every year, one of the factors causing the decline in production is the presence of pests and diseases. Sweet potato leaf curl virus (SPLCV) has been reported to infect sweet potatoes in Indonesia in 2022. Until now, there is no information regarding the variation in symptoms and severity of SPLCV disease in sweet potatoes. Therefore, this study aims to analyze the variation in symptoms and severity of SPLCV disease in Gianyar, Bali. The research was carried out directly in the field with observational parameters such as symptoms variation, incidence and disease severity. Observations were made every week when the plants were 63 to 91 days after planting (DAP). The results showed that SPLCV causes a variety of symptoms in the form of mild vein clearing, severe vein clearing, upward vein clearing, and downward vein clearing. The incidence and severity of the disease has increased every week. The incidence and severity of the disease were highest when the plants were 91 DAP, namely 73.33% and 40%, respectively. The high incidence and severity of the disease in the field is due to the use of stem cuttings from previous plants which may have been infected with SPLCV and whitefly vectors are always found in the field.

Abstract

Sorghum is one of developed plants for food diversification because it caontains nutrients and has the potential to be an alternative crop. This is also supported by the advantages of sorghum such as adaptive, drought tolerant, salinity tolerant, wide adaptabiliti and lower water requirements for season compared to other commodities. Behind its advantages, soghum has low vigor and viability. Low vigor and viability cause low growth simultaneously. The uneven growth of sorghum makes fertilizer application and harvesting more difficult. It also increases labor costs because maintenance and harvesting cannot be done at the sam time. This can be overcome by seed priming. The purpose of seed priming is to increase the germination rate, percentage of gemination, simultaneity of growth and germination speed. This research was conducted in a controlled temperature room using a factorial randomized block design. First factor is 3 sorghum varieties and the second factor is kind of solvent (Water, Hot water, KNO3, and Ascorbic acid). The result showed that there was an interaction between sorghum varieties and kind of solvent. KNO3 gives optimal results in all sorghum varieties compared to other ingredients.

Abstract

Rubber plants that have produced can be improved through iles-iles farming. This study aims to determine the effect of the iles-iles rubber intercropping system on soil fertility, rubber growth, and latex yield. The study used a completely randomized block design (CRBD) with three replications. The treatment compared the rubber monoculture system with iles-iles rubber intercropping. The results showed that the cultivation of iles-iles as a rubber intercropping during the mature period of two years of observation did not inhibit the growth of rubber because it was not significantly different (P = 0.255) compared to the monoculture system but had a significant (P = 0.0013) effect on the latex yield. The BEP (Break Event Point) value of this farming system was achieved at the price of wet tubers of IDR 7.139 kg-1 with a production of 2.368 kg ha-1, while the value of the LER (Land Equivalent Ratio) in this farming system was 1.84.

Abstract

The use of liquid organic fertilizer (POC) is expected to improve soil physical, chemical and biological fertility. Soil fertility increases, maximum plant growth will increase production both in quality and quantity. This study aims to determine the effect of the interaction between the type of treatment and the dose of POC on the growth and production of eggplant. This study was a factorial experiment consisting of two factors, namely POC types consisting of 2 levels: POC kitchen waste (P1); Banana weevil POC (P2) and POC doses consisting of 4 levels: without POC (D0); 10 ml/tan (D1); 20 ml/tan (D2); 30 ml/tan (D3) with randomization according to a completely randomized design (CRD). Observations were made when the eggplant plants were 10 HST with an interval of 10 days until the plants were 40 days old. The parameters observed were plant height, number of leaves, stem diameter, fruit length per plant, fruit diameter, number of fruit per plant, and fruit weight per plant. Observational data were analyzed using variance, if the results were significantly different it was continued with the smallest significant difference test (LSD) at the 5% level. The results showed that there was no significant interaction between the type of treatment and the dose of POC on all observed parameters. The various POC treatments significantly affected the parameters of plant height and number of leaves at all observed ages, stem diameters at 20 30, 40 DAP, and fruit weight per plant. POC dose treatment significantly affected the parameters of plant height and number of leaves at all ages of observation, stem diameter at 20, 30, and 40 DAP, number of fruit and fruit weight of the plants. Giving banana weevil POC resulted in better eggplant growth and production than kitchen waste POC. POC dose of 30 ml/plant resulted in the best eggplant growth and production. Because the results of the study showed that the effect of POC dose was still linear (the higher the POC dose, the higher the production).

Abstract

Oil palm (Elaeis guineensis Jacq.) is a plantation crop that has a bright future. Soil management such as land clearing, burning, use of heavy equipment and fertilisation in oil palm plantations will affect changes in soil physical properties. This study aims to assess the physical properties of soil in various treatments (planting circle, dead interplant spacings and live interplant spacings) on Oxisol and Inceptisol soil types. This research was conducted in Rancabungur and Malingping Banbten in October 2021 - May 2022. The method used in this study was multistage random sampling. Soil samples were taken from the Malingping area of Banten for the Oxisol soil type (2005 and 2009 planting years), and the Rancabungur area for the 2005 Inceptisol soil type. Comparison of soil physical properties of Oxisol of 2005 planting year with Oxisol of 2009 planting year and the ratio of Oxisol soil type of 2005 planting year and Inceptisol of 2005 planting year in various treatments did not show significant differences in soil physical properties (organic matter, content weight, field capacity moisture content, permanent wilting point, and particle density) between planting circle, dead interplant spacings and live interplant spacings. However, there were significant differences in the physical properties of soil texture between each management and permeability.

Abstract

Sweet potato feathery mottle virus (SPFMV) (Potyvirus) was first discovered in Indonesia in 2018. No one has reported information about the incidence and severity of SPFMV disease. Therefore, this study aims to determine the incidence and severity of SPFMV in Gianyar, Bali. The research was carried out directly in the field with observational parameters such as symptoms, incidence and disease severity. Observations were made every week when the plants were 63 to 91 days after planting (DAP). The results showed that SPFMV causes purple ringspot symptoms. The incidence of the disease did not increase when the plants were aged 63 to 91 DAP, while the severity of the disease increased every week. The highest incidence and severity of the disease were 70% and 20.7%. The main cause of SPFMV infection in the field is probably due to the continuous use of stem cuttings from previous crops.

Abstract

Peanut (Arachis hypogaea L.) is widely cultivated both in monoculture and polyculture (usually with corn) on dry land in Madura. Generally, the soil types of Madura are grumusol, regosol, and mediterranean. These three types of soil each have different physical and chemical properties. The effect of the addition of phosphate-solubilizing bacteria on the three soil types is unknown. The study aimed to determine the response of peanut plant growth due to the addition of phosphate solubilizing bacteria, Pseudomonas fluorescens, in three different soil types. The research was conducted in the experimental garden of Agroecotechnology, Faculty of Agriculture, Universitas Trunojoyo Madura. The research design used a non-factorial completely randomized design (CRD) with six treatments and four replications. The treatment consisted of three types of soil, namely regosol, grumosol, and mediteran as well as with and without the addition of P. fluorescens. The results showed that the treatment had a significant effect on the parameters of plant height, number of leaves, number of pods, pod dry weight, seed weight, above-ground biomass, root dry weight, and plant P content. The treatment did not show a significant effect on the root-canopy ratio and P. fluorescens population parameters.
