The purpose of the study was to determine the effect of giving cocopeat as a planting medium and the results of onion extract on the growth of oil palm plants in pre nursery. This research was conducted at the People's Garden, Kel. Binjai Estate, Kec. South Binjai. Binjai City, North Sumatra, from December 2023 to March 2024. The research used a Factorial Randomized Group Design (RAK) with 2 treatment factors, the first factor Cocopeat consists of 3 levels of treatment, C0 = No cocopeat, only a mixture of topsoil with cow manure, C1 = 25% cocopeat and 75% topsoil mixture with cow manure, C2 = 50% cocopeat and 50% topsoil mixture with cow manure. The second factor, shallot extract with three treatment levels, namely E0 = 0 ml, E1 = 10 ml, and E2 = 20 ml. The parameters observed consisted of stem diameter (mm), plant height (cm), leaf area (cm2) and number of leaves (strands). The results showed that cocopeat treatment had a very significant effect on the growth of plant height, number of leaves and stem diameter. C2 (50% cocopeat and 50% topsoil mixture with cow manure) is the best treatment. The shallot extract treatment showed a significant effect on the growth of plant height, leaf area, and number of leaves, E2 (20 ml of shallot extract) was the best treatment.

The utilization of urea compost and fluid natural manure (LOF) is extremely fundamental for rice plants. Urea contains high measures of nitrogen which can be consumed by plants rapidly and is significant for plant vegetative development. Fluid natural manure (LOF) gives more adjusted supplements to plants, particularly N, P and K. Fluid natural manure (LOF) likewise plays a part in further developing soil structure. This exploration means to concentrate on the impact of utilizing different dosages of urea compost and fluid natural manure (LOF) on the development and yield of rice plants. The examination will begin from October to December 2023 and will be done in the Science Techno Park garden at Tribhuwana Tunggadewi College. Non-factorial Randomized Block Configuration comprising of 4 medicines and 5 replications, each with urea manure portions of 0 kg/ha, 200 kg/ha, 400 kg/ha, and POC 100 cc/15 L of water. Plant level, wet and dry load of stover, and dry load of grain were the factors noticed. The examination of fluctuation test was utilized to investigate the perception information, trailed by the most un-massive distinction test (SRD 5%). The exploratory outcomes showed that the organization of different portions of urea compost and the utilization of LOF truly affected every noticed variable. The 400 kg/ha urea manure treatment gave the best grain dry weight (52.6 g/bunch). A urea portion of 200 kg/ha is comparable to the suggested utilization of POC in expanding stover weight and grain yield.

Pengaruh Formulasi Cendawan Entomopatogen Metharizium anisopliae(Metchnikoff) Sorokin dan Beauveria bassiana(Bals.-Criv.) Vuill terhadap Pertumbuhan dan Daya Tahan Hama Penyakit pada Bibit Kelapa Sawit (Pre nursery)

Entomopathogenic fungi are fungi that can cause death to insect pests. Some reports state that entomopathogenic fungi are endophytic or can grow in plant tissue and are positive for plant growth and produce phenol substances that insects do not like. The study aims to determine whether the formulation of entomopathogenic fungi Metharizium anisopliae (Metchnikoff) Sorokin and Beauveria bassiana (Bals.-Criv.) Vuill given to pre-nursery oil palm seedlings can help increase growth and resistance to pests and plant diseases. The study used factorial RAK with 3 replications and 2 factors, namely M. anisopliae fungus (M) with 4 levels: M0 = 0 g (control), M1 = 5g, M2 = 10g, and M3 = 40g, and B. bassiana fungus (B) with 4 levels namely: B0 = 0g (control), B1 = 5g, B2 = 10g, and B3 = 40g. The research resultsshowed that sprouts could grow into seedlings well, with an average third leaves appearing at week 12 after planting. The results of ANOVA analysis showed that the treatment factor of M. anisopliae and B. bassiana fungus gave an effect that was not significantly different on the parameters of the number of leaves, plant height, stem diameter, leaf length, number of leaf spots, leaf spot area, number of insect bites, insect bite area, plant length, crown wet weight, crown dry weight, root wet weight, root dry weight and root crown ratio. In other words, adding various doses of mixed formulation of M. anisopliae and B. bassiana did not provide a response to trigger plant growth and prevent the undesirable effects of insects. There are suggested that the two fungi are already in the oil palm seedling tissue as endophytes but until the 12th week, they have not shown any effect as a growth promotor or preventive effect the seddling tissue not liked by insects.

Respon Pemberian Pupuk Nitrogen dan Media Tanam Terhadap Pertumbuhan Bibit Kelapa Sawit (Elaeis guineensis Jacq.) di Main Nursery

Oil palm (Elaeis guineensis Jacq.) is a plantation commodity that has become highly favored in Indonesia. The massive expansion of oil palm plantations through large-scale land clearing has created new problems that impact the availability of suitable land for oil palm cultivation, making it limited and difficult to obtain. Consequently, the land currently used for cultivation and nursery is less suitable. Producing high-quality oil palm seedlings is closely linked to maintenance practices, the use of superior varieties, and the growing media used during the nursery phase. The growing media is a significant determining factor as it is the medium in which plant roots develop and absorb various essential nutrients for the plant's survival. In addition to the use of growing media, the application of nitrogen fertilizer aims to increase the availability of nutrients that can be absorbed by the plant for optimal growth. This research aims to determine the effects of growing media and nitrogen fertilizer application, as well as the interaction between these treatments, on the growth of oil palm seedlings in the main nursery. The study employs a factorial Randomized Block Design (RBD) with 2 treatment factors. The first factor is the planting media with 3 levels of treatment (M1: topsoil (3 parts) and rice husk charcoal (1 part), M2: topsoil (3 parts) and compost (1 part), M3: topsoil (3 parts), rice husk charcoal (0.5 part), and compost (0.5 part)). The second factor is the application of nitrogen fertilizer with 4 levels of treatment (N0: control, N1: 4 g/polybag, N2: 8 g/polybag, N3: 12 g/polybag). The results show that the growing media has a significant effect on increasing stem diameter. Nitrogen fertilizer significantly increases plant height and stem diameter. The interaction between growing media and nitrogen fertilizer significantly affects the increase in stem diameter of oil palm seedlings.

The purpose of this study was to determine the effect of N fertilizer and ameliorant types on the growth, yield, and nitrogen absorption of pak choy (Brassica rapa L.) plants through wick fertigation systems in vertical cultivation in dry land. The research method used a split-plot design. The main plot is N fertilizer consisting of BPN + Urea, BPN + POC, and BPN + Urea + POC. The subplots are ameliorant types consisting of soil, soil: biochar (1:1), and soil: compost (1:1), which were repeated 3 times so that 27 total experimental combinations were obtained. The results showed that there was an interaction between N fertilizer and ameliorant types that could increase the growth and production of pak choy plants, where the interaction of BPN + Urea + POC treatment with ameliorant types of soil: biochar (1:1) gave the best results in observing the stem diameter and root length of pak choy plants. N fertilizer was able to increase the growth and production of pak choy plants, where BPN + POC gave the best results in observing the dry weight of the crown and N absorption of pak choy plants. The type of ameliorant is able to increase the growth and production of pak choi plants where the soil:compost (1:1) treatment gives the best results in observing plant height and the number of pak choi leaves.
