Abstract

The production of Cocoa in Indonesia is still relatively low, reached an average of 532.17 kg ha-¹, while Ivory Coast has reached 1.5 tons ha-¹ in 2013. One of the efforts to support the development of the cocoa plant is a breeding use of organic fertilizers, Vermicompost is an organic fertilizer that has a lot of nutrients and safe for plants and contains many microorganisms that needed land. While of effort to improve the performance of microorganisms in the soil by terralyt-plus. The research was conducted at the experimental farm of the Faculty of Agriculture and Animal Husbandry, University of Muhammadiyah Malang with an altitude of 560 meters above sea level, which held for 3 months. Research compiled using factorial randomized design consisting of two (2) factors. The first factor is vermicompost consists of 3 levels, namely: D0 = 0g/plant; D1 = 200g/plant and D2 = 400g/ plant. The second factor is Terralyt-plus comprises 3 levels: T0 = 0 ml/polybag, T1 = 20 ml/polybag, and T2 = 40 ml/polybag continued BNJ test with a level of 5%. Vermicompost fertilizer dosage of 400g/plant with the addition of Terralyt-plus 40ml / plants is the best treatment in all parameters of the cocoa plant (Theobroma cacao L.). Results from this study are in treatment plant height, a number of leaves and total leaf area were significantly different interactions occur while the stem diameter and the amount of chlorophyll there is no real interaction.

Abstract

Strawberry production in Indonesia has been on the rise in various regions, including Aceh, Riau, Jambi, DKI Jakarta, West Java, Central Java, East Java, and others. According to the Central Bureau of Statistics (2021), production fluctuated from 573.00 tons in 2019 to 559.00 tons in 2020, rebounding to 838.00 tons in 2021. Factors influencing production include land availability, proper fertilization methods, and planting media. Adequate fertilization, considering both dosage and frequency, plays a crucial role. The study, conducted at Balitjestro GreenHouse in Batu City, East Java, focused on the interaction between lime and fertilizer on strawberry plant growth and yield. Synthetic fertilizers, particularly phosphate fertilizers, are essential for plant growth. The research utilized a completely randomized design with two factors: CaCl2 lime (S) and phosphoric acid fertilizer (R), resulting in two treatment combinations (4x4). Each treatment, repeated three times, yielded 48 experimental units, with one plant per unit. Results indicated that the addition of CaCl2 lime and phosphoric acid fertilizer had a minimal impact on strawberry plant growth and production. Specific combinations, such as calcium chloride and phosphoric acid fertilizer with KCL 7.2 grams and urea 12.5 grams, did not significantly affect vegetative growth parameters like plant height and leaf count. However, these combinations did influence strawberry plant production. The study underscores the need for careful nutrient management to optimize strawberry production in Indonesia.

Abstract

Potatoes (Solanum tuberosum L.) are carbohydrate-rich crops. Low potato productivity in Indonesia stems from farmers' inadequate access to quality seed potatoes. One solution to this issue is enhancing quality seed potato production, achievable through aeroponic systems. Lighting, whether incandescent or LED, can optimize potato mini tuber propagation in aeroponic systems. Research on lighting's effects on potato growth remains incomplete. This study aims to investigate how lighting color and duration affect mini tuber production of Solanum tuberosum L. PPT4 Zebra using aeroponic systems. Conducted in Jurangkuali, Bumiaji sub-district, Batu, the study employed a split plot design. The main plot consisted of lighting colors (WC): light yellow (WK), white (WP), and purple (WU). Subplots were lighting duration (LP) at 3 hours (LP 3) and 5 hours (LP 5), each replicated four times. Each replication comprised 8 samples, with 18 potato plant cuttings per population. Variables included plant height, stem diameter, leaf count, chlorophyll level, root length, tuber count, tuber diameter, budding seed count, and tuber weight. Data were analyzed using F-tests followed by BNJ tests at a 5% significance level. Results indicated no interaction between lighting color and duration. Purple lighting yielded the highest tuber count and weight, while 3-hour lighting duration yielded superior plant height, stem diameter, leaf count, and root length.

Abstract

Vermicast is a used soil from worm maintenance that is product composting from its maintenance in the form of organic fertilizer and it is very suitable for plants. Vermicast contains various ingredients needed by plants that is hormones such as gibberellins, cytokinins, and auxins, and contains of nutrients (N, P, K, Mg and Ca) and Azotobacter sp. which is a non-symbiotic N-fixing bacterium which can help enrich the N element for plants. In the use of vermicast can be solid or liquid. The purpose of this research is to determine the effect of dosage and vermicast with different ingredients of feed as organic fertilizer for shallot. This research was conducted at the FPP Experiment Garden UMM in Tegalgondo Village with a height of ± 560 m above sea level. The study used a Randomized Block Design with two factors. The first factor: worm feed ingredients (K) consist of (K1); Blotong waste (K2); rumen waste (K3); combination of blotong and rumen waste. The second factor: the dosage of administration (U) consists of (U1); 4 Ton / ha (U2); 5 Tons / ha (U3); 6 Tons / ha (U4); 7 tons / ha. This research included nutrient content in vermicast and on the growth of shallot including: Length of plant, number of leaves, number of tubers, weight of fresh plant, weight of dry plant. The results of this research showed that the dosage and feed ingredients given had no significant effect on plant height parameters, number of leaves, weight of fresh plant, and weight of dry plant of shallot (Alium asconolicum L.) for However it was given significant effect for the height parameters of the plant at the age of 13 HST and the number of leaves at the age of 13 HST. And the best is the combination of K3U3 (Vermicast which is given a combination of blotong and rumen waste feed ingredients) with a dosage of 54 grams / plant.
