Abstract

This research aims to determine the use of shallot skin liquid organic fertilizers on the growth of eggplant plants and determine the application of different doses to eggplant plants. The method used in this research used a factorial Randomized Block Design (RAK) with two factors where the first factor was eggplant variety M1: Mustang F1, M2 : LagunaF1, and the second factor was the dose of Liquid Organic Fertilizer (POC) shallot skin V0 : no POC shallot skins, V1 : 20 ml/L POC of shallot skins, V2 : 40 ml/L POC of shallot skins, V3 : 60 ml/L POC of shallot skins, V4 = 80 ml/L POC of shallot skins. The results showed that shallots skin POC on both varieties did not provide significant interaction. Shallots skin POC independently affected plant height and number of leaves, with the highest results in the V4 treatment with an average of 26.00 cm and 21.84 strands. While in the parameters of the result, the V4 treatment showed the highest results in fruit weight, namely 243.99 g. Onion skin POC can increase eggplant plant growth with the highest dose of 80 ml/L..

Abstract

The research aims to obtain the type of substrate and dosage of AB Mix that can elevate the growth of pagoda mustard plants. The study used a completely randomized design with four substrates: wood powder, charcoal husk, sphagnum moss, and cocopeat. AB Mix uses two doses such as 6 and 8 ml/l repeated 4 times in each experiment with three plant samples. Observations included parameters of plant height, number of leaves, leaf area, wet weight of plants and roots, and dry weight of plants and roots. The results showed that the husk charcoal substrate with AB Mix 8 ml/l nutrition produces the highest wet weight of pagoda mustard plants.

Abstract

Stevia (Stevia rebaudiana is a natural sweetener plant that can potentially be cultivated in Indonesia. However, the seedlings often experience suboptimal growth. This research aims to study the effect of chitosan and humic acid application at various doses on the growth of stevia seedlings. The research was conducted from June to August 2024 at the Standard Testing Center for Sweetener and Fiber Crop Instruments Karangploso, Malang, East Java. The study used a non-factorial Randomized Group Design (RAK) with 6 treatment levels and repeated 4 times for each treatment. The treatments tested consisted of K0H0 (0 ml chitosan and 0 ml humic acid), K0H1 (0 ml chitosan and 6 ml humic acid), K0H2 (0 ml chitosan and 12 ml humic acid), K1H0 (10 ml chitosan and 0 ml humic acid), K1H1 (10 ml chitosan and 6 ml humic acid) and K1H2 (10 ml chitosan and 12 ml humic acid). The results showed that the best treatment was chitosan 10 ml without humic acid (K1H0) which gave an effect on increasing plant height, root length and also the number of leaves of stevia seedlings.

Abstract

The success of budding is influenced by various factors, including the technique employed and the application of Plant Growth Regulators (PGRs). This study aimed to determine the most effective budding technique and type of PGR to enhance the success rate and initial growth of Siam Pontianak citrus (Citrus nobilis var. microcarpa) seedlings. The research was conducted from March to May 2025 in Batu City, East Java, using a Factorial Randomized Complete Block Design (RCBD). The first factor was the budding technique: patch budding, T-budding, and chip budding. The second factor was the type of PGR: control (water), young coconut water (500 ml/L), and Atonik (1 ml/L). The analysis of variance (ANOVA) revealed no significant interaction between the two factors. However, as independent factors, the chip budding technique resulted in the highest success percentage and number of shoots (P0.05). The application of coconut water led to the fastest sprout emergence, as well as the greatest shoot height and number of leaves compared to the other PGR treatments and the control. It is concluded that chip budding is the superior method for graft union success, while coconut water is the most effective PGR for promoting the initial vegetative growth of the budded seedling.

Abstract

This study aims to determine how the application of rice husk biochar and nitrogen fertilizer (urea), affects the chemical properties of dryland soil and the vegetative growth of sorghum (Sorghum bicolor L. Moench). This study was conducted from September 2024 to March 2025 at the Science Techno Park of Tribhuwana Tunggadewi University in Malang, East Java, using a Factorial Randomized Block Design with two factors: urea doses (0, 100, 150 and 200 kg ha-1) and biochar (0 and 5 tons ha-1) three replications. The parameters observed were pH H2O, total N-P-K, Organic-C, plant height, stem circumference, number of leaves, and leaf length and width. The results showed that the use of rice husk biochar and N fertilizer in dryland significantly interacted only on the parameter of sorghum plant height at 8 WAP. The use of the N3 dose (urea fertilizer dose of 200 kg ha-1) showed the most optimal results, but the N2 treatment (urea fertilizer dose of 150 kg ha-1) can be considered more efficient because the use of a lower dose of N fertilizer (urea) produced results that were not significantly different from the N3 treatment. Treatment B1 (5 t biochar ha-1) showed better results than B0 (no treatment).
