Abstract

Nematodes Meloidogyne spp. is the most important phytonematode in the world, especially in agriculture in tropical areas. The level of root damage to tomato plants caused by the nematode Meloidogyne spp. can reach 68.3%. In general, control of plant parasitic nematodes is still carried out using pesticides in the form of insecticides which can also be used as nematicides. Continuous use of chemicals to control nematodes can cause environmental pollution, resurgence and nematode resistance to chemicals. One alternative control is biological. One of the biological agents that can be used to control Meloidogyne nematodes is the endophytic fungus Beauveria bassiana and Trichoderma asperellum. The research aims to obtain the best isolates of endophytic fungi for controlling rootknot nematodes (Meloidogyne spp.). The isolates tested were 2 Beauveria bassiana isolates and 2 Trichoderma asperellum isolates. The results showed that the fungus isolate Beauveria bassiana isolate TD312 had a higher ability to control Meloidogyne spp on tomatoes.

Abstract

Organic matter has an important role besides providing macro and micro nutrients to plants, it can also improve environmental quality. The fermentation of rabbit urine and coconut water is expected to optimise the growth of honje seedlings. The aim of this study was to determine the concentration of fermented rabbit urine and coconut water that can optimise the growth of honje seedlings of Tasikmalaya accession. The study used a completely randomised design with seven treatments, namely A = control, B = 25% rabbit urine fermentation, C = 50% rabbit urine fermentation, D = 25% coconut water, E = 25% rabbit urine fermentation + 25% coconut water, F = 50% rabbit urine fermentation + 25% coconut water, G = 50% rabbit urine fermentation + 50% coconut water. The results showed that the treatments gave significantly different results on shoot emergence, seedling height, seedling diameter, and root crown ratio. Treatment G produced the fastest shoot emergence (6 days), and plant height (10.4 cm). Meanwhile, the widest seedling diameter was produced by treatment B (4.4cm), C (3.9 cm), and treatment G (3.9cm). Treatment C produced the highest root crown ratio of 0.5.

Abstract

The problem with tobacco farmers in Nagari Baruah Gununang is a productivity. Tobacco productivity is below national productivity due to cultivation techniques that do not comply with standards. The research method uses suitability analysis to assess the level of suitability of cultivation techniques used by farmers in Nagari Baruah Gunuang. The level of suitability is analyzed using check sheet based on a likert scale by comparing farmers actual and standards cultivation. The research results show that suitability level of tobacco cultivation technique is 70%. This means that the cultivation techniques used by farmers are still classified as almost in accordance with standards. The stages of cultivation that do not meet standards are planting; fertilization; and weeding, watering and loosening. The problems that cause non-compliance with this standard are close spacing of plants, lack of use of manure and dolomite, inappropriate dosage and type of chemical fertilizer, and insufficient watering and irrigation.

Abstract

Bananas (Musa spp.) are tropical plants that are very popular in Indonesia. Banana plants in the nursery require a planting medium that contains the nutrients the plants need. Tithonia is an annual weed that is suitable for use as a source of plant nutrients. This research aims to determine the effect of giving Tithonia liquid extract on the growth of Barangan banana seedlings resulting from tissue culture at the seedling stage and the best dose for using Tithonia liquid extract. This research was conducted at the Germplasm Nursery and Breeding Laboratory of the Tropical Fruit Plant Research Institute, Solok, West Sumatra, from September to December 2020. This research used the RAL method (Completely Randomized Design) with four treatments and six replications, in the form of 1) Without Tithonia extract, 2) Giving 1 ml of Tithonia extract, 3) Giving 2 ml of Tithonia extract, and 4) Giving 3 ml of Tithonia extract. The parameters observed were plant height, number of leaves, leaf length, leaf width, and stem diameter. Data was tested statistically. If calculated F > F table then it is tested further using the Duncan Multiple Range Test (DNMRT) with a level of 5%. The results of the research showed that giving Tithonia liquid extract had an effect on the growth of Barangan banana seedlings resulting from tissue culture. Significantly different results were obtained for the leaf width increase parameter. On the other hand, the results were not significantly different for other parameters such as plant height, number of leaves, leaf length and stem diameter. Giving 1 ml of Tithonia liquid extract was the best dose in this study.

Abstract

Weeds are plants whose presence is unwanted by humans because of competition with cultivated plants for nutrients, sunlight, and growing space, producing allelochemicals that interfere with plant growth, reduce production and product quality, and increase farming costs. The continuous use of synthetic herbicides has adverse effects on the environment and health, so it is necessary to seek a weed control mechanism that is more efficient and environmentally friendly. One is utilizing secondary metabolites, namely sunflower plant allelochemicals, that can control weeds. This study aims to determine the response of weeds to the application of extracts of sunflower plant parts as bioherbicides. This research was conducted in three stages: raw material preparation, extraction, and application. The results obtained 17 weed species in the experimental field of Nagari Selayo Tanang Bukit Sileh from 7 families (Asteraceae, Poaceae, Lythraceae, Polygonaceae, Brassicaceae, Caryophyllaceae, and Mazaceae) and two weed classes (broadleaf weeds and grasses). The bioherbicide efficacy of sunflower extract (Helianthus annus L.) has not caused symptoms of toxicity in weeds.

Abstract

There is ample opportunity for cocoa (Theobroma cacao L.) plantations because the world demand for cocoa increases every year. Cocoa plants bear fruit every year without knowing the season so cocoa cultivation provides promising prospects. The demand for cocoa must be balanced with increased in production from the cultivation scale from providing seeds to expanding cocoa planting land. The experimental design used in this study was a two-factor Randomised Group Design, namely the provision of AMF F0 (without AMF) and F1 (with AMF). The second factor is cocoa waste compost in planting media (v/v) with five levels, namely k0 (0%), k1 (5%), k2 (10%), k3 (15%),and k4 (20%). The aim of the research was to see the effectiveness of AMF and cocoa waste compost on the growth of cocoa seedling. Based on the research results, it can be concluded that the treatment of FMA can increase plant height, root volume, root dry weight, and percentage of colonized roots. Cocoa seedlings gave the best response with a dose of 0% cocoa waste compost with AMF treatment, with an average height of 60.19 cm . The percentage of AMF colonization is high at 44.6%. The final soil analysis showed an increase in P-available pH and soil Ald with mycorrhiza and cocoa shell compost treatment at a dose of 10%

Abstract

One effort that can be made to reduce starfruit damage is harvesting at the right stage of maturity and choosing the proper packaging. The research objective was to obtain the right maturity stage and type of packaging to reduce the percentage of damage and preserve quality during the distribution process of starfruit. The research was carried out at the Trilogi University. The harvesting and packaging process was carried out at Attaqie Farm, East Java. The study was conducted from October 2022 to March 2023. The method used was a Completely Randomized Design with two factors; the first factor was the stage of maturity (S), consisting of 2 levels: S-4 and S-5). The second factor was the type of packaging composed of 4 levels: cardboard packaging (fruit sealed with newspaper); cardboard packaging (fruit sealed with newspaper and foam net); basket packaging (fruit sealed with newspaper); and basket (fruit sealed with newspaper and foam net), replicated three times. The variables observed were the percentage of fruit damage, °Hue value, taste scoring, Total Dissolved Solids (TDS), and Total Titratable Acidity (TTA). The research results showed that starfruit could still be accepted by consumers until the 6th day, with the best treatment in SK-4, which is basket packaging type (fruit sealed with newspaper and foam net). This treatment had good results, as indicated by the damage percentage value of 7.67%, taste score of above 3.5, TDS of 9.66, °Hue value of 99.89 with less bright colors, and TTA of 0.50.
