Abstract

Fertilisation in the pre-nursery phase of oil palm plants is very important. Fertilisation can increase the growth of oil palm seedlings, make plants healthy, etc. The purpose of this research is to see the effect of each fertiliser used on several growth parameters of oil palm seedlings. The purpose of this research is to see the effect of each fertiliser used on several growth parameters of oil palm seedlings. the method used in this research is a group randomised design with 5 treatments and 10 replicates. The treatments/fertilisers used in this study were urea fertiliser, P fertiliser, NPK fertiliser, and oragnik cari fertiliser made from active mycorrhiza. The parameters observed were plant height, plant diameter, and leaf length of oil palm seedlings. observations were made every week with a frequency of 3 observations. the results of this study are that each fertiliser has a different effect on each observation parameter and frequency of observation. NPK fertiliser and urea fertiliser were significantly different from other treatments in the first observation of plant height. While in plant diameter, liquid fertiliser made from active mycorrhiza tends to be significantly different from other treatments. In leaf length, the results showed an irregular pattern. However, in the mycorrhizal fertiliser treatment, the number of leaves exceeded 1 of the other treatments.

Abstract

National food needs to focus on the agricultural sector. Tomato production in Indonesia is still low compared to other countries. This research aims to determine the impact of using husk ash and various types of compound fertilizers on the growth and yield of tomato plants. This study was conducted at KP2 INSTIPER Maguwoharjo, Special Region of Yogyakarta, in April-July 2023. This research used a Completely Randomized Design (CRD) composed of 2 factors. The first factor is the dose of husk ash, which consists of 3 levels, namely: 50g/polybag (control), 60g/polybag, and 70g/polybag; the second factor is the type of compound fertilizer, which consists of 3 types, namely; NPK 15:15:15, NPK 16:16:16, and NPK 9:25:25 at a dose of 10g/plant. Based on these two factors, 9 treatment combinations were obtained, each repeated 3 times, so there were 27 experimental plants. The research data was analyzed using variance with an actual level of 5%. The analysis results show an interaction between abusekam and compound fertilizer on the parameters of fruit diameter, average fruit weight, fresh shoot weight, and root fresh weight. Application of husk ash at a dose of 60g and NPK 15:15:15 gave a fruit diameter of 46.33 mm. Giving 70g of husk ash affects plant growth, fruit number, and fruit/plant weight. Providing NPK16:16:16 compound fertilizer has a good effect on plant growth, fruit number, and fruit/plant weight.

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

Penyakit bercak daun yang disebabkan oleh patogen Curvularia sp. dapat menyebabkan persentase serangan hingga 93,29% dan intensitas serangan sebesar 47,13%. Banyak faktor yang menyebabkan pesatnya perkembangan penyakit ini, antara lain kondisi tempat penyemaian, gulma, sertifikasi pembibitan, teknik pengendalian, lokasi pembibitan dll. Penelitian ini bertujuan untuk menganalisis faktor di pembibitan yang menyebabkan tingginya serangan penyakit bercak daun. Metode survei yang digunakan dalam penelitian ini adalah purposive sampling dengan mengambil sampel >80 bibit pada setiap lokasi pembibitan. Lokasi pembibitan yang diambil sampel sebanyak 9 lokasi pembibitan kelapa sawit. Data dianalisis dengan menggunakan uji T (perbandingan populasi) pada setiap faktor pendukung perkembangan penyakit. Hasil penelitian menunjukan terjadi perbedaan yang signifikan pada persentase dan intensitas serangan penyakit pada faktor tempat penyemaian kelapa sawit, lokasi pembibitan kelapa sawit, keberadaan gulma di pembibitan kelapa sawit, sertifikasi pembibitan kelapa sawit, dan jenis bibit kelapa sawit. Namun pada intensitas serangan bercak daun pada jenis bibit kelapa sawit menunjukan tidak berbeda secara signifikan.

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

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. Keywords: Inorganic, Biofertilizer, Organic, Rice, Fertilizer
