Abstract

Sweet potatoes are propagated using vegetative propagation, especially cuttings. The cuttings used can come from the shoots and stems. During the distribution to farmers, the cuttings undergo temporary storage that useful to help maintain moisture, temperature, and air circulation in an optimum state. The study aimed to determine the effect of variety, type of cuttings, length of storage, and their interaction on vegetative growth and potential cuttings produced by sweet potato plants. The study was arranged using a three-factor factorial Randomized Block Design with 4 replications. The first factor was sweet potato varieties composed of 2 levels, specifically Antin 3 (V1) and Beta 1 (V2). The second factor is the cuttings types composed of two levels, specifically shoots (S1) and stems (S2). The third factor is the storage period, which consists of 3 levels, specifically without storage (P0), 1 week of storage (P1), and 2 weeks of storage (P2).  The observed variable consisted of cutting growth rate, primary branch length, secondary branch length, and number of branchs and cuttings potential. The results showed that the Beta 1 variety had better growth than the Antin 3 variety based on the criterion  of shoot growth, secondary branch length, and cuttings potential. Beta 1 has a longer shelf life than Antin 3, which can be stored for 1 week. Cuttings planting material storage can reduce all observation criterion, specifically growth capacity, primary branch length, number of branchs, secondary branch length, and cuttings potential. Cuttings derived from the shoots produced better plant length than stem cuttings in the treatment without storage.

Abstract

The decreasing area of agricultural land due to conversion to residential use threatens food security and the sustainability of the agricultural sector, so efficient and nutritious cultivation alternatives are needed. Microgreens, young vegetables that are rich in nutrients and can be cultivated on limited land, are a potential solution whose success is greatly influenced by the growing medium. This study aimed to analyze the effect of growing media on the growth and protein of spinach and kale microgreens. The research was conducted in Jambewangi in August-November 2024 using a two-factor completely randomized design (CRD), namely planting media (husk charcoal, cocopeat, Malang sand, and rockwool) and vegetable types (kale and spinach greens), each with three replications. The results showed a significant interaction between vegetable species and planting media on the fresh weight of plants at the age of 14 HST. The best treatment was found in husk charcoal × kale, cocopeat × kale, and rockwool × kale. The highest protein content was recorded in sand × spinach (6.05%), while the highest total chlorophyll was in cocopeat × kale (38.80 µmolm-²). The selection of appropriate growing media proved to have a significant effect on the vegetative growth and nutritional quality of microgreens.

Abstract

Shallot (Allium ascalonicum L.) is an important horticultural commodity that contributes significantly to Indonesia's economy. However, its production declined in 2022–2023 compared to 2021. Fertilization plays a key role in improving soil fertility and supplying nutrients for optimal plant growth. This study aimed to assess the growth and yield response of the Brebes shallot variety to various doses of bokashi fertilizer and to determine the most effective dose. The experiment used a Randomized Complete Block Design (RCBD) with one factor: bokashi dosage, consisting of six treatments—B0 (control), B1 (1 kg/m²), B2 (1.5 kg/m²), B3 (2 kg/m²), B4 (2.5 kg/m²), and B5 (3 kg/m²). Each treatment was replicated four times with ten plants per replication, totaling 280 experimental units. The results indicated that bokashi application significantly affected leaf length, leaf diameter, bulb length, bulb diameter, fresh and dry bulb weight, as well as total yield per clump. The highest growth and yield were observed at the 3 kg/m² dosage. Thus, bokashi at 3 kg/m² is considered the most effective dose for improving the growth and productivity of the Brebes shallot variety.

Abstract

Organic farming is an environmentally friendly cultivation system that prioritizes natural ingredients and avoids the use of synthetic chemicals. To support peanut growth, this system relies on compost as a source of nutrients. Compost is believed to be rich in natural nutrients and can improve soil conditions. The proper use of compost is expected to increase peanut productivity in Indonesia, which is currently still low. The purpose of this study was to determine the effect of compost fertilizer dosage on the growth and yield of peanut plants. This study used a Completely Randomized Design (CRD), with one factor, namely the compost fertilizer dosage, repeated 3 times. The treatment consisted of several compost fertilizer dosages, namely C0 without compost; C1 compost 20 ml/L; C2 compost 40 ml/L; C3 compost 60 ml/L. The results of this study were that the C1 dosage (20 ml/L) was the most optimal for vegetative growth, producing much better plant height compared to other dosages, and pod weight (yield): the C3 dosage (60 ml/L) was the most effective for the generative phase, producing significantly the highest pod weight. Keywords: Compost, Dosage, Organic, Peanuts, Production

Abstract

The presence of Rottboellia exaltata weeds is one of the factors causing crop failure in agricultural land such as corn cultivation. Praxelis clematidea weeds and lerak fruit were found to have allelopathic effects in suppressing the growth of many plants. This study aims to determine the effect of P. clematidea and lerak fruit extract formulations on the germination and growth of R. exaltata weeds. The study was conducted from July to October 2025 in Bandar Lampung City and the Weed Science Laboratory, Faculty of Agriculture, University of Lampung. The study used a completely randomized block design (CRBD) with 5 replications. The treatments consisted of 5 formulations of P. clematidea and lerak fruit extracts, namely P0 = control (without extract); P1 = 50% P. clematidea extract; P2 = 50% lerak fruit extract; P3 = 25% P. clematidea extract + 75% lerak fruit extract; P4 = 50% P. clematidea extract + 50% lerak fruit extract; P5 = 75% P. clematidea extract + 25% lerak fruit extract. The results showed that post-emergence application of a mixture of P. clematidea extract + lerak fruit extract inhibited weed growth. The inhibitory effect of 75% P. clematidea extract + 25% lerak fruit extract was higher than that of other formulations on weed height, number of leaves, dry weight of shoots, dry weight of roots, and total dry weight of weeds. The low crown/root ratio, weed toxicity level of 78.67%, and the highest weed suppression percentage of R. exaltata at 67.64%.
