Abstract

This study was conducted to determine the response of corn plants to the second cob pruning treatment and liquid complementary fertilizer (LCF) spraying on the Growth and Production of Waxy Corn Plants (Zea mays ceratina L.). This study was conducted at the Experimental Garden of Pabentengan Bajeng Village, Gowa Regency, South Sulawesi, from September to December 2018. The materials used in this study were local waxy corn seeds, liquid complementary fertilizer (Bram Evolution) urea and NPK fertilizer. The Split Plot Design method was used. The main plot is without pruning and with pruning, while the sub-plot is Spraying Liquid Complementary Fertilizer (LCF) consisting of 4 levels, namely without LCF spraying, spraying with a concentration of 10 mL/L water, 20 mL/L water, and 30 mL/L water, 8 treatment combinations repeated 3 times to obtain 24 experimental units. The results of this study indicate that pruning the second cob increases the dry weight of the plant, seed weight per plant, seed weight per plot, and seed weight per hectare. LCF spraying and the interaction between pruning and LCF spraying treatments did not affect the observed parameters

Abstract

The need for rice as one of the main food sources increases along with the population of Indonesia. One of the obstacles to increasing rice productivity is pest attacks. In the rice fields, there are predatory insects which are important as pest control agents in rice plants. Coccinella sp is a type of predator that is often found in rice plantations. The urgency of this research is the need to conserve natural enemies such as managing flowering plants and providing additional food (supplements) to predators. This is because planting flowering plants in rice fields will hinder or disrupt farmers' roads and if flowering plants are not managed properly they will become nesting places for mice, so it would be better to formulate these flowering plants into artificial syrup. This study aimed to determine the preferences of insect predators for various forms of pellets and various types of flowers. The treatments in this study were kenikir and Zinnia (Zinnia elegans). In each experiment, all treatments were put into a petri dish and a predatory imago, Coccinella sp., was released in the middle. From testing the predator response of Coccinella sp. for Kenikir and Zinnia flower syrup which were rated the best by observing the average frequency of Coccinella sp. attending each treatment with the length of time used. The experiment was arranged using a completely randomized design (CRD) treated with ANNOVA. The results showed that the response of the natural enemy Coccinella sp. frequency of visits was most often to white Zinnia flower syrup which was sweetened with brown sugar solution and the longest was to yellow kenikir flower syrup which was added to honey solution.

Abstract

Sweet potatoes, particularly the VitAto variety, are well-known for their richness in beta-carotene and vitamin C, making them a potential source of nutritious food. However, post-harvest preservation and storage remain significant challenges as they can affect the produce's quality, taste, and nutritional content. Therefore, evaluating the preservation and storage of VitAto sweet potatoes is crucial to extend their shelf life and minimize post-harvest losses, thereby supporting local food security.The objective of this study was to evaluate the post-preservation and storage performance of VitAto sweet potatoes during the storage period. The study employed a quantitative approach to assess the effectiveness of preservation and storage methods. Sweet potato samples were randomly selected based on uniform criteria and preserved using drying, waxing, and natural preservatives. The samples were stored under various conditions (room temperature, refrigeration, humidity, and storage duration) and evaluated based on their physical, chemical, and organoleptic qualities.The results showed that an 8-week storage period caused significant changes in VitAto sweet potatoes. Moisture content decreased, weight loss increased up to 11.28%, and total soluble solids (TSS) rose from 12.08 Brix to 17.46 Brix. The skin color changed, with increased redness (a*) and yellowness (b*), while the flesh color remained stable until week six before lightness (L*) began to decline. The pH values, as well as Chroma and Hue parameters, remained relatively stable. These changes reflect physiological and biochemical processes during storage, providing valuable insights for optimizing shelf life and maintaining the quality of VitAto sweet potatoes

Abstract

Waxy corn (Zea mays L. var. ceratina) is one type of corn that is popular because of its delicious, soft, and chewy characteristics, both in young and old seed processing. The obstacle that often arises in increasing production in the field is the availability of nitrogen-containing fertilizers such as urea, which are often rare and expensive. Reducing the nitrogen dose is attempted by only relying on NPK base fertilizer. The provision of a minimum dose of NPK base fertilizer (200 kg/ha) was studied in this study. The purpose of this study was to analyze the effect of nitrogen adequacy doses on the growth and production of waxy corn plants. This research was conducted at the Greenhouse of the Faculty of Agriculture, UMI Makassar, South Sulawesi Province. This research was designed in the form of a 2-factor factorial Randomized Block Design. Factor I consisted of Putra Baru 1, Putra Baru 2, and Arumba varieties, and factor II was urea fertilization at a dose of 100 kg/ha and without urea (control). Observations of growth and production components were observed when the plants were 100 HST old. The results showed that plant height and cob diameter had no significant effect. The weight of cobs per plant of the Putra Baru 1 and Putra Baru 2 varieties is higher than that of the Arumba variety. Urea fertilization of 100 kg/ha has a good effect on cob weight. There is no interaction between varieties and urea fertilization. An additional dose of 100 kg/ha of urea is needed if using a minimum NPK base fertilizer (200 kg/ha) to increase production

Abstract

Indonesia is the third-largest cocoa (Theobroma cacao L.) producer in the world and the twelfth-largest exporter of cocoa, making this commodity one of the subsectors of agriculture with significant potential in the national economy and state revenue. However, cocoa productivity in Indonesia from 2019 to 2022 has not yet reached its optimal potential, with production in 2022 reaching 667.3 thousand tons. Cocoa exports from Indonesia over the past five years have been dominated by cocoa beans, accounting for 99% of total exports. Indonesian cocoa has strong competitiveness in international markets. One of the cocoa production centers in Indonesia is West Sulawesi, specifically in Mamuju Regency. This region produces high-quality Lindak cocoa with a distinct flavor and higher polyphenol content compared to cocoa from Côte d'Ivoire, Ghana, and Malaysia. However, the area for cocoa development in Tommo District, Mamuju Regency, has experienced a decline, impacting productivity over the past five years. This challenge is related to various factors, including land suitability, cultivation technology, and post-harvest management. To enhance cocoa production in the Tommo District, it is necessary to evaluate land suitability both qualitatively and quantitatively. This evaluation will identify limiting factors and estimate production value based on land use. The results of this evaluation can provide information regarding the economic feasibility of cocoa development in the area, which is expected to improve farmers' incomes and support sustainable agriculture.

Abstract

This study was conducted to determine the effective concentration of Trichoderma sp. against Phytophora palmivora. This study was conducted in the disease laboratory, Department of Pests and Plant Diseases, Faculty of Agriculture, Hasanuddin University. This study was carried out from March to August 2024. The method used in this study was the Detached pod test method, namely looking at cocoa fruit that had been infected with Phytopthora palmivora fungus consisting of five treatment levels T0 (Control), T1 (giving concentration 105), T2 (giving concentration 106), T3 (giving concentration 107), T4 (giving concentration 108). The parameters observed were the area of Phytopthora palmivora fungal spots on the surface of cocoa fruit and identification of the results of cocoa fruit isolation. The results showed that the treatment with a concentration of 106 had an average area of spots with a value of 8.73 mm2, which was the lowest value compared to other treatments. Treatment with a concentration of 106 showed effective control in inhibiting the growth of Phytophora palmivora and can be considered as an alternative in disease control strategies.

Abstract

The growth of mung beans needs to increase plant productivity by evaluating land suitability for maximum results. The study aimed to determine the characteristics and quality of land and land suitability classes and limiting factors for developing mung bean plants in the Tabongo Subdistrict. The study was conducted from February to May 2024 in the Tabongo Subdistrict of Gorontalo Regency. The study used a matching method between the quality and characteristics of the Tabongo Subdistrict land with the criteria for land suitability for mung bean plants to produce actual land suitability classes and potential land suitability classes. Data was processed by analyzing land quality, characteristics, and suitability classes. The study's results showed that the actual land suitability class for green beans was dominated by class S3 (marginally suitable) and N (Not Suitable) with each class having different sub-classes, namely S3tc,wa,na,eh covering an area of 778.38 ha (74.70%), S3tc,wa,na covering an area of 176.31 ha (16.92% and S3tc,wa,rc,na with an area of 48.75 ha (4.68%). This class has limiting factors of temperature, water availability, rooting media, Available Nutrients, Erosion hazards, and Land preparation. Class S3 also dominated the potential land suitability class with an area of 1003.44 ha and N covering an area of 38.61 ha. It can be concluded that the land suitability class for green beans in the Tabongo sub-district is quite large, dominated by the marginally suitable class (S3) of 96.29%, and the remaining 3.71% have land suitability class N (Not Suitable).

Abstract

Basil (Ocimum basilicum), mint (Mentha spp.), and sambung nyawa (Gynura procumbens) are herbal plants with various benefits, both for culinary and medicinal purposes. Basil is known for its distinctive aroma and is often used in cooking and traditional medicine due to its essential oil content, which has antioxidant and anti-inflammatory properties. Mint, with its refreshing taste and aroma, is widely used in beverages, food, and medicines, especially for relieving digestive disorders. Meanwhile, sambung nyawa is a medicinal plant believed to help lower high blood pressure, improve immune function, and possess antioxidant properties. These three plants have great potential in the fields of agriculture and health. This study aims to examine the effect of NPK 15:15:15 fertilizer on the growth of three plant species: Basil (Ocimum basilicum), Mint (Mentha spp.), and Sambung Nyawa (Gynura procumbens). The research used a Randomized Block Design (RBD) with two treatments: N0 (control): no fertilizer application, and N1: NPK 15:15:15 fertilizer applied at a dose of 1.5 grams per plant. Parameters observed included plant height, number of leaves, canopy width, and chlorophyll content. The results showed that Basil (Ocimum basilicum) responded most significantly to the NPK 15:15:15 fertilizer compared to Mint (Mentha spp.) and Sambung Nyawa (Gynura procumbens). Basil showed significant improvement in all observed parameters, especially between 10-15 days after application (DAA). These results indicate that the application of NPK 15:15:15 has the potential to enhance the growth efficiency of Basil compared to the other two plants.

Abstract

Carbon is an important nutrient for building soil organic matter which is needed in agricultural activities. Cultivation activities in paddy fields increase carbon gas emissions into CO2 into the atmosphere, especially in irrigated rice fields. This study aims to determine the level of content and map the distribution of organic carbon in paddy fields in Pallangga District, Gowa Regency. The research was carried out in Pallangga District, Gowa Regency from December 2021–January 2022. The research method used the free grid method with a total of 33 samples and map interpolation using ArcGIS software. The results showed that the status of the level of organic carbon content was in the very low to low criteria. The level of organic carbon content is very low, namely T8 8.83 tons/ha, T9 7.85 tons/ha, T10 9.74 tons/ha, and T11 9.20 tons/ha. While the low organic carbon content is T1 which is 12.76 tons/ha, T2 points 11.76 tons/ha, T3 10.92 tons/ha, T4 12.98 tons/ha, T5 12.90 tons/ha, T6 11 .66 tons/ha, and T7 is 13.06 tons/ha. The mapping area of low criteria organic carbon distribution is only 27% or 850 ha of the total area, while 73% or 2,338 ha is categorized as very low. Based on these results, it is necessary to take action on agricultural land management, especially rice fields that are friendly to carbon emissions, one of them is stabilizing the use of chemical and organic fertilizers, the organic material produced by such cultivation activities as straw is not burned and returned to the soil so that it could maintain fertility and quality of soil and improve the physical, chemical, and biological conditions needed for sustainable agricultural development.
