Abstract

The improper use of pesticides can lead to significant negative impacts on both the environment and human health. This study evaluates horticultural farmers' compliance with recommended pesticide practices in Ogan Ilir Regency, South Sumatra, and examines the effects on pests, diseases, natural enemies, and pesticide residues in their products. This research used a direct survey method on horticultural crop cultivation land in Ogan Ilir Regency, South Sumatra, and sent plant samples to be tested for pesticide residue levels. The results showed that low-compliance farmers had high pest populations, high disease incidence, and fewer natural enemies, while high-compliance farmers had low pest populations, low disease incidence, and more natural enemies. Pesticide residue tests indicated that products from low-compliance farmers contained Amitraz residues of 0.02 mg/kg and Chlorantraniliprole residues of 0.14 mg/kg, while medium-compliance farmers had Amitraz residues of 0.02 mg/kg and Chlorantraniliprole residues of 0.18 mg/kg. No pesticide residues were detected in products from high-compliance farmers. The study concludes that adherence to recommended pesticide use significantly influences the balance of agricultural ecosystems and the safety of agricultural products.

Abstract

The agricultural sector plays a strategic role in food security and environmental sustainability; however, it faces challenges such as declining productivity and pollution due to synthetic chemicals. This study aims to identify antagonistic fungi from organic lands and test their effectiveness in controlling Fusarium sp. pathogens as part of integrated pest management. The methods employed include exploration, isolation, identification, and antagonistic fungi testing on Potato Dextrose Agar (PDA) media. The results revealed four types of identified fungi, including light green, brown, and black, which belong to the Aspergillus sp. and dark green is Trichoderma sp. species. The light green antagonistic fungus effectively suppressed the growth of Fusarium pathogens by 57.84%, while the dark green fungus showed a suppression rate of 32.32%. This study emphasizes the potential of antagonistic fungi as effective biocontrol agents in sustainable agriculture.

Abstract

Bud sett is one type of sugarcane planting material that is efficient in terms of size, allowing the distribution process in large quantities from variety producers to users. However, its smaller size than mule-shaped planting material will cause the freshness of bud sett planting material to decrease more quickly during storage due to the delayed planting period. The purpose of this study was to determine the impact of delayed planting at various storage periods of bud sett sugarcane seeds on the initial growth and production of sugarcane seeds. This study used a Randomized Block Design with 3 replications. The treatment of delayed planting period was 5 levels, namely without storage period (T0), storage period 1 x 24 hours (T1), storage period 2 x 24 hours (T2), storage period 3 x 24 hours (T3) and storage period 4 x 24 hours jam (T4). The data were analyzed variously and tested for the mean value using the Least Significant Difference (LSD) test at the 5% level. The results showed that the weight and germination of bud setts decreased with increasing length of the delayed planting period. In general, the storage period for bud sett seeds does not have a significant effect on seedling growth and seedling production.

Abstract

Cocoa seeds are recalcitrant seeds, namely seeds that cannot tolerate drying, and are sensitive to low temperatures and humidity. Naturally, cocoa seeds do not have dormancy, have low shelf life and are sensitive to changes in the storage environment. Therefore, proper handling is required after the seeds arrive at their shipping destination (after the seeds have been stored during shipping). Among them is by providing growth regulator (ZPT) treatment, so that seed vigor can be maintained. Cocoa plants can grow well if planted in media with a composition of organic materials and nutrients needed by the plants. This research aims to look at the interaction of natural growth hormones and planting media on cocoa seeds which experience a decrease in quality on the growth of cocoa seedlings. This research used a split plot design with a RAL pattern consisting of a main plot which was a combination of planting media and sub plots which were natural growth hormones, each treatment was repeated 3 times. Each experimental unit consisted of 3 seed samples, so that 90 seeds were obtained. The research results showed that there was no interaction between the use of natural growth hormones and the composition of the planting medium on the parameters of seed water content, vigor index, germination power, growth speed, seed height, number of leaves, leaf area and root volume, as well as seed dry weight. The best hormonal treatment for the parameters of leaf area, root volume and dry weight of seedlings is a hormone from tomato extract. The best planting media composition is alluvial topsoil + chicken manure + husk charcoal (1 : 1 : 1).

Abstract

Black rice cultivated on land with low water content can adapt and grow well by utilizing rainfed land. Arbuscular Mycorrhizal Fungi (AMF) application increase water and nutrient absorption. Soil moisture plays role in the development of AMF. Attempt to maintain soil moisture can be balanced by applying rice straw to the land. This research aimed to examine the role of mycorrhiza and rice straw and their interactions independently in increasing the rate of assimilation and relative growth of black rice in rainfed rice fields. The experiment was conducted in Tebas District, Sambas Regency from July to December. This research method used a split-plot design with randomized block design consisted of main plot and subplot. The main plot was AMF treatment (without AMF and AMF administration), and the subplots were rice straw dosage (ton/ha) (0, 5, 10, 15). The experiment was repeated 3 times, 8 treatments and 16 observed plant samples and continued with Honestly Significant Difference (HSD) test with 5% level. Variables of this observation are leaf area, total dry weight, and net assimilation rate. The result showed that the interaction of AMF and rice straw treatment influenced leaf area, total dry weight and net assimilation rate. Keywords: Black Rice, Mycorrhizal, Rice Straw

Abstract

The lack of nutrient availability can lead to a decline in rice plant (Oryza sativa L.) productivity. One effort to increase plant productivity is fertilization. The aim of this journal review is to analyze the effectiveness of inorganic, organic, and biofertilizers on rice productivity. The method used is a literature review by analyzing published journals (2010-2024) on the effectiveness of inorganic, organic, and biofertilizers in rice plants. The review results show that inorganic fertilizers provide nutrients quickly; however, their long-term use is detrimental to environmental conditions and sustainable agriculture. Organic fertilizers can enhance soil microorganisms and improve soil structure, although their nutrient content is low. Meanwhile, biofertilizers enhance nutrient availability through nitrogen-fixing microorganisms. The combination of inorganic, organic, and biofertilizers is proven to be more effective in increasing rice productivity without harming the environment.

Abstract

Rice (Oryza sativa L.) plays a crucial role in Indonesia's food security. The use of high-quality seeds is essential to improve rice productivity. One of the factors affecting seed quality is seed physiology, particularly the physiological processes after harvest, known as after-ripening. After-ripening is a process that enables seeds to germinate after a certain period of dry storage. This study aims to determine the duration of the after-ripening period in several superior rice varieties and identify the variety with the shortest after-ripening period among those tested. The research was conducted at the Seed Analysis Laboratory, Lampung State Polytechnic, from November 2023 to January 2024, using a factorial Completely Randomized Design (CRD). The first factor was the after-ripening period (ranging from 0 to 6 weeks), and the second factor was the rice varieties (Gilirang, Inpari 42, and Inpari 43). Each experimental unit consisted of 100 rice seeds. Data were analyzed using ANOVA and further tested with Duncan’s Multiple Range Test (DMRT) at a 5% significance level. The results showed that the after-ripening period varied among the varieties. The Gilirang variety completed its after-ripening period within 1 week, while Inpari 42 and Inpari 43 required 2 and 3 weeks, respectively. The Gilirang variety demonstrated the shortest after-ripening period, than the Inpari 42 and Inpari 43 varieties.

Abstract

Weeds are one of the main inhibiting factors in the cultivation of ornamental plants, including roses, because they compete for nutrients, air and light. This research aims to inventory and analyze weed vegetation in lowland (Sidoarjo, 8 masl) and highland (Batu, 900–950 masl). The research method includes observation in sample plots measuring 1x1 meter with six plots at each location, followed by analysis using the Important Value Index (INP). The results show that in the lowlands, Teki weed (Cyperus rotundus L.) dominates with an INP of 191.27, while in the highlands, Jotang Kuda weed (Syndrella nodiflora) dominates with an INP of 52.08. These differences reflect the weed's adaptation to the environmental conditions of each location. Effective and sustainable weed control is very necessary to increase the productivity and quality of rose cultivation.

Abstract

Corn plants are considered as one of the staple crops in Indonesia. Corn is an important crop after rice as a source of carbohydrates, and corn has high strategic and economic value. In producing corn plants, their growth is very much determined by how they are managed. Several factors that greatly affect the decline in corn growth are the presence of weeds growing in cultivated land. The presence of these weeds can disrupt plants. In addition, weeds become competing plants for cultivated plants to get water, light and nutrients. The method used in conducting this weed diversity analysis is the quadratic method. The method used is to identify weeds found in corn plants in the highlands of Malang Regency and the lowlands of Siduarjo Regency. The results obtained from observations of weed vegetation in the highlands found 9 families, 12 species and 152 individuals, while in the lowlands found 2 families, 2 species and 173 individuals. The Ageratum conyzoides species in the highlands has the highest relative density, which is 48.05%, while in the lowlands, the Amaranthus viridis species has a relative density of 89.60%.
