Abstract

The study aims to determine the effect of leaf pruning time on the production and sugar content of sweet corn plants, analyze the effect of the location of sweet corn leaf pruning that provides the best production and sugar content, and analyze the effect of the interaction between leaf pruning time and pruning location on the production and sugar content of sweet corn plants. The study was conducted in January - March 2024 in an experimental field at the Gowa Agricultural Development Polytechnic (POLBANGTAN) Campus, Romanglopoa Village, Bontomarannu District, Gowa Regency. This study was conducted using a randomized block design (RBD) consisting of two factors. The first factor is the pruning time which consists of 3 levels: Leaf pruning at the age of 30 Day After Planting (DAP); Leaf pruning at the age of 40 DAP; and Leaf pruning at the age of 50 DAP. The second factor is the location of leaf pruning which consists of 3 levels, namely: Pruning 3 upper leaves; Pruning 3 lower leaves, and Pruning 1 upper leaf and 2 lower leaves. The results showed that pruning the three upper leaves at the age of 50 DAP produced the weight of the cob with the heaviest husk of 420.00 g and was significantly different from other treatments at the same age. The treatment between pruning at the age of 50 DAP and pruning the three upper leaves significantly affected the characteristics of sweet corn cobs, namely the diameter of the cob with the highest husk reaching 50.72 mm. The treatment of pruning at the age of 50 DAP with pruning the three upper leaves also affected the sugar content, with a brix content value reaching 15%, which was significantly different from other treatments at the same age.

Abstract

F2 seeds are a derivative of F1 cultivation grown in a medium containing cellulose. Sorghum seeds and corn seeds contain cellulose, hemicellulose, and lignin that can be used as innovative media for F2 seedling development and the growth of oyster mushroom mycelium. The purpose of this research is to determine the growth of F2 oyster mushroom mycelium on media of sorghum seeds and corn seeds that have been sterilized for 40 minutes and 60 minutes. The type of research used is an experiment with a Completely Randomized Design (CRD) in a factorial pattern consisting of 2 factors. Factor 1 is the media type: Sorghum Seeds, and corn Seeds. Factor 2 is the Sterilization Time: 60 minutes and 40 minutes. The parameters measured are the length of the mycelium, the spread of the mycelium, and the thickness of the mycelium in F2 oyster mushroom seedlings. Technical analysis uses quantitative descriptive data. Based on the results obtained regarding the growth of the F2 oyster mushroom mycelium, the highest growth was observed on sorghum seed media, measuring 13.81 cm, with a very thick and dense spread. The cellulose content affects the growth of the mycelium. Meanwhile, the lowest growth of the F2 oyster mushroom mycelium was found on corn seed media, measuring 11.27 cm, with a thin and uneven spread, and a density or thickness that is thin and sparse.

Abstract

The technique of propagating potato seeds through tissue culture has long been used to produce quality and disease-free seeds. This study aims to test the effect of the combination of BAP and Shallot Extract on the growth of potato plant explants on MS media (Murshige & Skooge). Research in experimental form uses a completely randomized design (CRD) in a factorial pattern consisting of two factors. As the first factor, the growth hormone BAP consists of 4 levels, namely: 0 ppm, 2 ppm, 3 ppm and 4 ppm. Meanwhile, the second factor is: shallot extract consists of 4 treatment levels, namely: 0%, 0.2%, 0.4% and 0.6%. Thus, there were 16 treatment combinations which were repeated 6 times so that the total experimental units were 96. The ABA treatment with a concentration of 2 ppm/liter gave the best effect on the shoot formation time and root formation time of AR 8 potato plant explants. However, the treatment without ABA had a good effect on Shoot length and root length of explant potato plant varieties AR 8. Shallot extract treatment with a concentration of 20% had the best effect on shoot formation time, root formation time, shoot length and number of leaves. However, the treatment with a concentration of 40% had a better effect on the parameters of the number of shoots and the number of explant segments of the AR 8 variety of potato plants. The interaction of the ABA treatment with a concentration of 2 ppm and the shallot extract with a concentration of 20% had the best effect on the time of emergence of shoots and roots on the AR 8 Potato Explants. However, the interaction without ABA (0ppm) and shallot extract had a better effect on the parameters of shoot length, number of leaves, and number of explant segments in the AR 8 potato variety.

Abstract

The absence of data regarding soil fertility within a watershed leads to the selection of land use that does not align with the appropriate level of land capability and suitability. The objective of this study is to assess the soil fertility index in different land uses within the Jenelata sub-watershed and identify the land map unit with the highest soil fertility. The study was conducted from February 2024 until May 2024. The study is a soil survey investigation that has been validated by laboratory analysis. The survey area comprises 23 Land Map Units (SPL) derived from the integration of soil type maps, slope maps, and land use maps. Each SPL is represented by three composite soil samples, corresponding to each land use category. Soil sampling was conducted at a depth of 0-30 cm. The observed characteristics include Cation Exchange Capacity (CEC), Organic Carbon (C-Organic), total Nitrogen (N), accessible Phosphorus (P), exchangeable Potassium (K), exchangeable Magnesium (Mg), exchangeable Calcium (Ca), and exchangeable Aluminum (Al). The soil analysis data are utilized to evaluate the soil fertility index. The study revealed that the soil fertility index value in the Jenelata sub-watershed ranged from 195 to 215, indicating a moderate to relatively high level. The maximum soil fertility index value of 215 was seen in the utilization of secondary dryland forest land.

Abstract

Pesticides are chemicals whose use is close to human life. Agricultural systems based on high energy input materials such as chemical pesticides can cause environmental pollution, especially the agricultural environment. Inappropriate use of pesticides endangers the health of farmers, consumers, and non-target microorganisms and has an impact on environmental pollution both soil and water. Data collection techniques with secondary data collection methods, where the author collects 10 articles and then processes the data into new data. The results showed that when the behavior and use of pesticides were classified as good criteria with a score of 65.9%, the environmental impact was also classified as good criteria. The impact of the use of pesticides found in farmers is in the form of nausea, vomiting, dizziness, itching on the skin. Of the 100 samples, most of them, 75%, experienced these health problems. The impact of using pesticides in agricultural activities on the environment and health can have good and bad effects depending on how the attitudes and behavior of farmers in using pesticides. Excessive use of pesticides, not in accordance with applicable regulations will cause pollution to the environment (soil pollution, water pollution and wild organisms and animals) and health problems that interfere with the physical condition of the farmers themselves such as dizziness, nausea and others, this is due to farmers who tend not to use personal protective equipment (PPE) when interacting with pesticides

Abstract

This research aims to develop Katokkon chilies outside their natural habitat with different environmental conditions. Increase soil fertility levels in areas with low fertility levels by adding manure and NPK fertilizer. The study used a two-factor randomized block design (RBD): NPK fertilizer and cow manure. NPK fertilizer consisted of 2 grams, 4 grams, 6 grams per 10 kg of soil, and control (without NPK fertilizer). Cow manure treatment consisted of 0.5 kg, 1 kg, and 1.5 kg per 10 kg of soil and without cow manure (control). Each treatment was repeated 3 times and consisted of 3 plants for each observation unit. The research results show that developing katokkon chili plants outside their natural habitat is still possible. Providing 0.5 kg of cow manure had the best effect on the parameters of plant height, fruit weight, and production of Katokkon chili plants. Adding 2 g NPK fertilizer provided the best growth in terms of plant height, fruit weight, and production parameters. However, the addition of 6 g NPK fertilizer affected the productive branch parameters of Katokkon chili plants. There was a real interaction between 0.5 kg cow manure and the addition of 2 g NPK fertilizer on the parameters of plant height, fruit weight per plant, and production of Katokkon chili plants

Abstract

Sweet potato plants require bed height and type of mulch for good growth and production. This research aims to determine the effect of bed height and mulch type on sweet potato (Ipomoea batatas L.) production. The study used a factorial randomized block design (RBD) with 2 factors. The first factor is the treatment of bed height and the second is the mulch type. The research was analyzed using analysis of variance and continued with an honest significant difference (HSD) test which will be done using the Excel application. The research showed that bed height and partial use of mulch significantly affected tuber production in sweet potatoes. The best bed height is 30 cm. The use of silver-black plastic mulch has a significant influence on sweet potato production.  The interaction between bed height and mulch type only significantly affected tuber length in sweet potatoes

Abstract

Phosphorus (P) is a very important macronutrient for plant growth and development. Plants cannot fully absorb phosphate in the soil, only 25% can be absorbed by plants while Al binds 75% in the soil. Plants absorb P from the soil in the form of phosphate ions, especially in the form of H2PO4- and HPO42- which are present in soil solutions. H2PO4 ion is more common in acidic soils, while higher pH (> 7) forms HPO42- is more dominant. The lack of P dissolved in the soil causes the plant to get P intake from other sources such as fertilizers. Efforts to increase the efficiency of Phosphate dissolution, currently the use of Phosphate solubilizing microbes have begun to be developed. This study aims to determine the number of isolated bacterial colonies, the ability of phosphate-solubilizing bacteria, and the levels of P-available before and after giving phosphate-solubilizing bacterial isolates. This research was conducted at the Laboratory of Plant Pests and Diseases and in the Laboratory of Soil and Environmental Conservation, Faculty of Agriculture, Universitas Muslim Indonesian, Makassar, Indonesia, from November to December 2020. The materials used in this study were HVS paper, aluminum foil, plastic wrap, labels, rubber, Pikovskaya media, sterile distilled water, plastic, cotton, tissue, 70% alcohol, rubbing alcohol, NA (Natrium Agar) media, soil samples from the vegetative and generative phases of rice rhizosphere from Tebba Village, Salomekko District, Bone Regency. This research method is a qualitative exploratory research based on data analysis. The results of this study indicated that the vegetative phase 3 rice isolates with 10-5 dilution had the highest number of colonies, namely 9,200,000 CFU /ml. Plant generative phase 3 rice isolate at 10-5 dilution had the highest average phosphate solubility with an IPF value of 5.56. Plant generative phase 3 rice isolate had the highest average P-available before and after the addition of Phosphate Solubilizing Bacteria isolates, namely 3.83 ppm, and after the addition of Phosphate Solubilizing Bacteria isolates increased to 9.58 ppm.
