Abstract

Pakchoy plants (Brassica chinensis L. ) is a plant that much in demand by the public because of high nutritional content. The limited agricultural land currently caused pakchoy cultivation declined, one of the ways that can be used to overcome this problem is to utilize the limited land by verticulture manner. Nutrients and water is a very important factor for plant growth of pakchoy, thus providing a variety of growing media and the provision of water can improve plant growth and production. Research has been conducted on the home screen Technical Services Unit Faculty of Agriculture, University of Riau from September to November 2014. The research conducted experimentally using Completely Randomized Design (CRD) consist 2 factors: embedding medium and the volume of water. The first factor is the growing medium consisting of three types of medium, M1=inceptisol soil, M2= 75% Inceptisol  and 25% cocopeat, M3= 75% inceptisol and 25% ash sawdust and the second factor consists of 3 volumes of water that V1=100 ml/day, V2=200 ml/day, V3= 300 ml/day. Parameters measured were plant height, number of leaves, leaf area, fresh weight, weight suitable for consumption and root volume. The results showed that the volume of water with planting medium ash sawdust effect on growth and yield of pakchoy. Provision of water volume of 200 ml and the embedding medium ash sawdust with vertikultur system gives the best effect on plant height, number of leaves, leaf area, plant fresh weight, fresh weight of plants suitable for consumption, and root volume.   Keyword: pakchoy, medium, water volume, verticulture

Abstract

Red chilies are one of the horticultural commodities that have high economic value in Indonesia. Red chili production in Indonesia in 2021 will reach 136 million tons, with Riau province experiencing a decline in production which causes a production deficit in the province. To increase production, it is necessary to improve red chili cultivation techniques. The growth of red chili plants is influenced by internal and external factors, including ideal rainfall ranging from 600 mm/year to 1,250 mm/year. Rainfall that is too high can cause air humidity to increase and plants are more susceptible to disease. Red chili plants also require slightly hot daytime temperatures and sufficient water availability. In the rainy season, the risk of red chili crop failure is high because the plants cannot tolerate standing water. Excess water can cause plant root rot and diseases such as bacterial wilt and anthracnose. Therefore, it is necessary to develop red chili cultivation techniques in the rainy season, such as making the right planting schedule, understanding cultivation techniques, and using technical cultural measures such as making higher beds and using appropriate pesticides. With the right cultivation techniques, it is hoped that it can increase farmers' income and welfare. Red chili cultivation can also provide large profits if revenue is high and production costs are low. Therefore, it is important to optimize efforts to increase red chili production by using appropriate cultivation techniques during the rainy season. The aim of this community service activity is to increase public knowledge about cultivating chili plants during the rainy season in Teluk Piyai Pesisir.

Abstract

The oil palm plant is one of the plantation commodities that plays an important role in economic activities in Indonesia. Cultivating oil palm plants as monocultures causes the environment to be favorable for insect pests to attack the plants. To overcome this, it is necessary to observe the types and populations of pests on palm oil plants. This research aimed to obtain information and data regarding the types and populations of pests and insects on palm oil plants (Elaeis guineensis Jacq.) in Kuantan Singingi Regency. The research was conducted from June to August 2024. The research method was a survey method, and plant samples were taken randomly (purposive random sampling). There were 9 sample plots, where each plot was observed on 13 plants, and the total number of plants observed was 117. The observed parameters were the condition of the agroecosystem, the type of pest on the palm oil plants, the percentage of attacked clumps, the percentage of attacked plants, and the intensity of pest attack. The result showed that the found pests were Metisa plana, Orgyia sp., Oryctes rhinoceros, Setora nitens, and Tirathaba mundella. The dominant pests were Metisa plana (208 individuals), Setora nitens (98 individuals), Orgyia sp (129 individuals), and Tirathaba mundella (42 individuals). There were also non-pest insects, Spinaria spinator, Utethesia pulchelliodes, and Creatonotos gangis.

Abstract

This study aims to evaluate the effects of super K organic fertilizer application on the flowering phases, yield components, and the relationships among observed variables of oil palm (Elaeis guineensis Jacq.), as well as to determine the fertilizer dose that provides the best response in yield components. The study was conducted over six months, from March to September 2024. The experiment was arranged in a Completely Randomized Design (CRD) with four levels of super K organic fertilizer application, namely K1 = 3 kg plant⁻¹, K2 = 4 kg plant⁻¹, K3 = 5 kg plant⁻¹, and K4 = 6 kg plant⁻¹. Each treatment was replicated five times, yielding 20 experimental units. Each experimental unit consisted of two sample plants, for a total of 40. The collected data were analyzed using analysis of variance (ANOVA) and further tested using Duncan’s New Multiple Range Test (DNMRT) at the 5% significance level. The results showed that super K organic fertilizer application had no significant effect on the time to spathe emergence, time to flower emergence, time to female flower receptivity, time to male flower anthesis, sex ratio, and the number of fresh fruit bunches harvested per plant. However, super K organic fertilizer significantly affected the fruit maturation period and fresh fruit bunch weight per plant, with the 5 kg plant⁻¹ dose providing the best performance. Correlation analysis revealed strong to powerful relationships among several flowering variables and oil palm yield components.
