Abstract

The application of mucuna bracteata D.C compost fertlizer and ZPT ( growth regulator) substances to oil palm seedlings alms to determine the effect of interaction between mucuna bracteata D.C fertilizer and ZPT NAA. The single effect of mucuna bracteata D.C fertilizer on the growht of oil palm seedlings in the pre-nursery phase this research was conducted in the experimental, Alwashliyah university from Nov 2024 to january 2025. This research was conducted using a randomized block Design (RAK) with a two- factor factorial pattern. And each combination was repeated 3 times. The fist factor is mucuna bracteata D.C fertilizer with four doses of 0  g 1 g 10 g and 15 g and a recommendatioon f 10 g. The second factor dose with four treatments of 0 gr 0,5 gr 1 gr and 1,5 gr observation variables such as growht . the parameters of this study were the percentage of plant life , length of ol palm stems, Number of leaves (strands) root length (cm) total wet weight of plants, total dry weight of plants. The results of the study showed that the higher the amount of Mucuna bracteata compost and  NAA Auxin ZPT given, the better growth of oil palm seedlings. This can be seen in the parameters of 100 % survival life, root length of 2,66 cm, number of leaves of 4.88 strands, root length of 3,75 cm, total wet weight of 4.65 g and dry weight of 2.41 g.

Abstract

Providing NPK fe rtilize r and mycorrhiza with Ultisol soil media aims to de te rmine the effect of inte raction be twe en NPK fe rtilize r and mycorrhiza, single effect mycorrhiza. Single influence of NPK pupul on the growth of oil palm se e dlings in main nurse ry. This research was carrie d out in the experimental garden at the Faculty of Agriculture Jambi University from August 2023 to Octobe r 2023. This re search carrie d out using a Randomize d Block De sign (RAK) with a patte rn factorial of two factors. and e ach combination is re pe ate d 3 time s. Factor first NPK fertilize r with thre e dose s of 10 g 6.7 g 3.4 g. and re comme ndation of 10 g. Se cond factor mycorrhiza dose with thre e tre atme nts of 10 g 6.7 g 3.4 g. and recommendation of 10 g. Variable Obse rvations such as seedling he ight, number of le ave s, ste m diame te r, rachis le ngth, and leaf area. The results of this re se arch show that the combination of mycorrhizal fertilize r and NPK fe rtilize r dose s can increase the growth of oil palm se e dlings in the main nurse ry. the combination of 10 g of mycorrhizal fe rtilize r + 10 g of NPK fe rtilize r gave the be st growth compare d to without a combination of mycorrhizal fe rtilize r and NPK fe rtilize r. Giving 10 g of mycorrhizal fe rtilize r + 10 g of NPK gave the highe st re sults in the parame te rs of plant he ight, numbe r of le ave s, le af are a. The interaction between NPK fertilizer and mycorrhizal biofertilizer treatments had a significant effect on the parameters of plant height and diameter of oil palm seedling tubers in the main nursery.

Abstract

This research aims to determine the influence of interactions between mycorrhiza and NPK fertilizer. This research was carried out in the experimental garden of the Jambi University Faculty of Agriculture from August 2025 to October 2025. This research was carried out using a Randomized Group Design (RAK) with a factorial pattern of two factors and each combination was repeated 3 times. The first factor is NPK fertilizer with three doses of 10 g 6.7 g 1.8 g. and the recommendation is 10 g, while the second factor is biological fertilizer with three doses, namely 10 g 6.7 g 3.4 g. and recommendation 10 g. The observed variables were seedling height increase, leaf number increase, stem diameter increase, rachis length, and leaf area. The results of the study showed that the combination of mycorrhizal and NPK fertilizer doses could improve the growth of oil palm seedlings in the main nursery. The combination of 10 g of mycorrhizal biofertilizer + 10 g of NPK fertilizer provided the best growth compared to without the combination of mycorrhizal and NPK fertilizer. The provision of 10 g of mycorrhizal + 10 g of NPK provided the highest results in the parameters of plant height, number of leaves, and leaf area.

Abstract

Fall Armyworm (FAW) or armyworm (Spodoptera frugiperda J. E. Smith) is an insect native to the United States that is invasive to Indonesia. Pest control can be done with natural/biological compounds derived from plants which are an alternative to chemical insecticides. The purpose of this study was to observe the toxicity response of contact poison extract of Tithonia diversifolia kipahit leaves against S. frugiperda larvae. This study was conducted in the laboratory of the Faculty of Agriculture, Islamic University of North Sumatra, Jl. Karya Wisata Gedung Johor. Medan Johor District, Medan City, North Sumatra, with an altitude of ± 25 m above sea level (meters above sea level) with flat topography. This research was conducted from June 20, 2025 to August 16, 2025. This research used a non-factorial Completely Randomized Design using several treatments, namely k0: control, k1: 0.1%, k2: 0.2%, k3: 0.3%, k4: 0.4%, and k5: 0.5%. By using Analysis using IBM SPSS Statistic 20. Observed parameters S. frugiperda pest level, Lethal concentration LC50 and Lethal Time LT50. The results showed that the administration of kipahit leaf extract (T. diversifolia) using contact poison application in this study had a significant effect on the mortality of S. frugiperda larvae, the highest mortality was at a concentration of k5 (0.5%) which was 77.50%, the higher the concentration of contact poison given, the faster the mortality process of S. frugiperda larvae.
