Abstract

Common problems in cashew tree development are low plant productivity caused by the use of unqualified seeds and limited knowledge of seed handling. This research was aimed to study the role of the mother tree on the growth of cashew seeds and study the seedling and growth of cashew trees in several planting media. The method used was Completely Randomized Design (CRD), consisting of two treatment factors and 4 replications. The first factor was the planting medium consists of 4 types: soil; soil: manure (2: 1); husk charcoal: manure (2: 1); soil: charcoal husk: manure (1: 1: 1). While the second factor was the origin of the seeds from the parent tree with fruit colors red, green, yellow, pink. The results showed that the planting soil medium was very significantly affected by increasing plant growth, namely plant height, number, and leaf area. The interaction between media and seed origin was not significantly affected plant growth. The best seed growth was found on soil media, plant height reaches 31.750 cm, number of leaves with 19 leaves, with an area of 48.437 cm2.

Abstract

The productivity of red ginger in Indonesia has decreased by 9,174 tons compared to 2017. The decrease is due to the very limited area of red ginger production, the method of red ginger cultivation, which is still very conventional, and the low amount of organic matter in the soil. This study examines the effect of planting media composition on the growth and production of red ginger. The study used a Completely Randomized Block Design (RCBD) with six treatments, namely control (soil without manure), cow manure: green manure: soil (1:1:1), P2 = goat manure: green manure: soil (1:1:1), green manure: soil (1:2), cow manure: soil (1:2), and goat manure: soil (1:2) and repeated four times. Composition media of goat manure: green fertilizer: soil with a ratio of 1:1:1 could increase the growth of red ginger in variable plant height, number of leaves in the clump, leaf area, and the weight of fresh stover with a yield of 52.7 cm; 10,75; 148,5; 2952.59 cm2; and 307.33 g. Composition of green fertilizer media: soil with a ratio of 1:2 could increase the weight of dry stover with a value of 39.32 g, and red ginger production includes fresh weight of rhizomes 111.32 g, storage weight of rhizomes 107.87 g, and rhizome volume 124.12 cm3.

Abstract

Consumption of herbal medicines by Indonesian people is increasing because of the price and ease of obtaining them. One of the main ingredients of herbal medicine is mint leaves because they contain tannin and flavonoid secondary metabolites. However, the generative mint plant is very slow and needs vegetative cuttings propagation. This study aims to examine the effect of auxin-type growth regulators and the composition of the growing media on the growth and yield of mint plant cuttings. This study used a complete randomized block design with two factors. The first factor was the auxin growth regulator with four levels: without growth regulator, IBA 500 ppm, IAA 500 ppm, NAA 500 ppm. The second factor was the composition of the planting medium with three levels, namely soil, husk charcoal, and goat manure 3:3:1; 3:2:2, and 3:1:3. Three repetitions were carried out. Auxin affects the number and area of leaves. Applying 500 ppm NAA encouraged the highest leaf growth, with the number of leaves at 163.38. Growth regulator NAA 500 ppm increased the number of leaves and leaf area of mint plants, i.e., by 0.01% and 1.16% compared to the control. The growing media composition affected the crown fresh weight, root biomass, and crown root ratio. The media composition of 3:3:1 produced a crown fresh weight of 41.07 g, and the media composition 3:3:3 produced the highest biomass of 5.97 g. The media composition 3:1:3 showed the highest root crown ratio, 2.69%. Auxin and the composition of the growing media synergistically promote the growth and yield of mint cuttings.

Abstract

Optimization of shallot production can use True Shallot Seed (TSS) and Plant Growth Regulator (PGR) + Boron formulation. The purpose of the study was to identify superior varieties that respond to the concentration of PGR + Boron formulation and can provide the best results. The research location was at 7°32’30” N and 110°48’32” E, from October 2023 to February 2024. A randomized complete block design factorial with two treatment factors was used, each repeated three times. The first is the type of variety (Lokananta, Maserati, and Sanren), the second is the type of PGR + Boron formulation, the composition of GA3+BAP+Boron (ppm:ppm:kg.ha-1) with four levels, that were 0:0:0, 50:25:2, 100:50:2, and 150:75:2. Conclusion, The Maserati variety of shallots from TSS with a PGR formulation of 100 ppm GA3 + 50 ppm BAP + 2 kg.ha-1 Boron produces better growth and yields than the Lokananta and Sanren varieties.
