Abstract

Weeds are nuisance plants that grow in unwanted areas and inhibit the growth of paddy rice cultivation, which can reduce the quantity of rice yield Therefore, weeds need to be controlled. This study aims to determine : 1) the effect of using 10% Ethyl pyrazosulfuron herbicide on the growth of Rojolele Srinuk variety of paddy rice (Oryza sativa L. var. Rojolele Srinuk) and 2) the correct dose of 10% Ethyl pyrazosulfuron herbicide for the growth of Rojolele Srinuk variety of paddy rice. This research was conducted in Langensari Village, Tarogong Kaler District. The research was conducted from November 2022 to February 2023. This study used a Randomized Group Design (RGD) with seven treatments and four repetitions, including 10% Ethyl pyrazosulfuron herbicide treatment at a dose of 150 g/ha (0.18 g/12 m2 ), 225 g/ha (0.27 g/12 m2 ), 300 g/ha (0.36 g/12 m2 ), 375 g/ha (0.45 g/12 m2 ), 450 g/ha (0.54 g/12 m2 ), manual weeding and control. The results showed that the use of 10% Ethyl pyrazosulfuron herbicide at a dose of 150 g/ha (0.18 g/12 m2 ) - 450 g/ha (0.54 g/12 m2 ) did not cause phytotoxicity or symptoms of poisoning to Rojolele Srinuk variety of paddy rice plants. Then, the use of the herbicide Ethyl pyrazosulfuron 10% affects the number of tillers of rice paddy varieties Rojolele Srinuk. The most effective dose of 10% Ethyl pyrazosulfuron herbicide in the growth of Rojolele Srinuk rice paddy is a dose of 450 g/ha (0.54 g/12 m2 ).

Abstract

Fish waste and Tithonia diversifolia are the essential ingredients of organic fertilizer. Several researchers have already tested these two materials, which have high plant nutrient content. This study aims to determine the effect of liquid organic fertilizer from marine fish waste and tithonia application on shallot (Allium ascalanicum L.) production. The research was conducted in Kuranji Subdistrict, Kuranji District, Padang City, West Sumatra, Indonesia, at 15 meters above sea level from November 2022 to March 2023. The experiment used a completely randomized design (CRD) with six treatments and four replications, resulting in 24 experimental units. The data were analyzed using analysis of variance (ANOVA) with a significance level of 5%. If there was a significant effect, Duncan's New Multiple Range Test was conducted at a significance level of 5%. The treatments consisted of 0, 10, 20, 30, 40, and 50 ml/L. The application of liquid organic fertilizer from marine fish waste and tithonia at 40ml/L is the most effective for shallot production, yielding the highest production per hectare at 12.13 tons/ha

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.

Abstract

Potatoes are crops that have economic value and are rich in benefits because they contain good and relatively beneficial substances. In the production of the Granola L potato variety, tissue culture propagation is used. Many factors affect the growth and development of potato plants, one of which is light. Light is needed by plants to perform photosynthesis, and the photosynthate will be distributed to all parts of the plant through the transport network. The purpose of this research is to see the effect of various light conditions on the growth of Granola L potato explants. The design used is a Completely Randomized Block Design with variance analysis and further testing using Duncan's Multiple Range Test. The treatments used are neon light (1000 lux) (A), room light (250 lux) (B), and no light (C). The variables observed were the number of living explants, plant height, number of leaves, and root length. Observations showed that the number of living explants is strongly influenced by the planting media and the environment, which must be sterile. For the variables of plant height and root length, the highest data were shown by treatment C compared to treatments A and B. This is because the explants experienced etiolation, leading to stem and root elongation. For the number of leaves, the highest data were shown by treatment A, followed by treatment B, and the lowest by treatment C. Therefore, for good growth, Granola L potato explants require light.
