This research was conducted at the Screen House of the Faculty of Agriculture, University of Pasir Pengaraian, from July 2022 to October 2022. The design used in this study was a Completely Randomized Design (CRD) with 5 treatments, namely P0 = Without adding oil palm. frond compost, P1 = 25 g/polybag of palm frond compost, P2 = 50 g/polybag of palm frond compost, P3 = 75 g/polybag of palm frond compost, P4 = 100 g/polybag of palm frond compost. The results showed that the application of various doses of palm frond compost significantly affected the parameters of the number of fruits per tomato plant. Still, they had no significant effect on the parameters of plant height, number of leaves, and flowering time. The P4 treatment, namely applying palm frond compost at a dose of 100 g/polybag, tended to produce the best observation parameter: the number of fruits per plant. In contrast, the plant height parameter tended to be better with applying palm fronds. frond compost.","PeriodicalId":296594,"journal":{"name":"JURNAL AGRONOMI TANAMAN TROPIKA (JUATIKA)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114944635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The acclimatization stage is a critical period in plant propagation. The factors that most influence the growth of in vitro seedlings in the acclimatization process are suitable planting media and the administration of biostimulants. This study aimed to obtain the best planting medium and type of biostimulant for the growth of black orchid plantlets at the acclimatization stage. The study used a completely randomized design with a factorial pattern with two factors, namely first factor: type of growing media with 5 levels of treatment (wood sawdust, coconut coir, cocopeat, rice husk, sugarcane dregs) and second factor: type of biostimulant (without biostimulants; Moringa oleifera extract; Centella Asiatica extract; and Melastoma malabathricum extract). The results showed that the highest percentage of plantlet survival (100%) in the early stages of acclimatization was shown in plantlets grown on wood sawdust and coconut coir media. At the advanced acclimatization stage, the type of biostimulant significantly affected the parameters of survival percentage, tiller height, average number and width of leaves, and average number and length of roots. Optimal planting medium and biostimulant type for advanced acclimatization orchid growth is a single treatment of wood sawdust media with a tiller survival rate (100%), the highest number of leaves (4.65 strands), most roots (8.4 strands).","PeriodicalId":296594,"journal":{"name":"JURNAL AGRONOMI TANAMAN TROPIKA (JUATIKA)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121709790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The application of compost and empty palm fruit clusters was able to chelate Al-DD and increase the soil's available P and K. There is a positive Pearson correlation between pH, Ca, K, and Mg, as well as a positive Pearson correlation between all observed growth and development parameters of soybean plants.

Palm fronds and coconut shells were pyrolyzed using a simple combustion device in the form of a pyrolysis drum. Combustion with pyrolysis drums is carried out in a closed manner in the absence of oxygen for 2-5 hours. Parameters observed were lignocellulose of palm fronds and coconut shells, spectrographs, chemical properties of Biochar of palm fronds and coconut shells, and physical properties of peaty soil after applying Biochar of palm fronds and coconut shells. The pH, total C, total N, C/N, total P, available P, total K, total Na, and the volume and pore size of the coconut shell biochar showed higher results than the palm frond biochar. However, the results of the analysis of total Mg, total Ca, CEC and ash content and surface area on palm frond biochar showed higher results than coconut shell biochar.

The form of organic fertilizer consists of three levels: banana stems, water hyacinth, and manure. The second factor is the organic fertilizer dosage, which consists of three levels: 100g, 250g, and 300g. Five repetitions yielded nine treatment combinations and one control treatment (plants without organic fertilizer ) from these treatments. Observations included plant height, leaf count, stem diameter, fresh crown weight, dried shoot weight, root length, fresh root weight, dry root weight, and root volume. The results demonstrated a significant interaction between the type and dosage of organic fertilizer on the parameters of plant height, root length, shoot fresh weight, root fresh weight, and root volume.

Traits observed were plant height, tesseling flowering date,  silking date, seed dry accumulation rate, effective seed filling period, cob length, cob weight, number of seed rows, number of seeds per cob, seed weight per cob, the weight of 100 seeds and seed yield per m2. Analysis of variance was performed to the data using SAS and further tested by honesty significant difference at 5% level. Variance component, heritability, genetic correlation coefficient, and selection response were calculated for all characters and effective seed filling duration. The results indicated that the genetic variance component was significant for all characters except for the dry matter accumulation rate. All characters' heritability values were quite high except for effective seed-filling duration and the number of seeds per cob. Phenotypic correlation coefficients were positively significant between seed yield per m2 and plant height, seed development rate, cob length, ear weight, number of seeds per ear, seed weight per ear, and weight of 100 seeds.

Observational data were analyzed using analysis of variance at 5% significance level, followed by Duncan's multiple distance test at 5% significance level. On the chemical properties of the soil, the interaction of giving Calcite and Kiserite occurred at pH and Ca media. Calcite increases the pH and Ca media. Kieserite increases Mg and decreases Ca media. The application of Calcite and Kiserite significantly increased the yield of leaves and stover, but there was no interaction between them.
