Abstract

Chaya leaves (Cnidoscolus aconitifolius (Mill.) I.M. Johnst.) are leafy vegetables that contain many vitamins and minerals. Information about the intensification of chaya cultivation is still rare. Chaya propagated by stem cuttings. The maturity level of stem cuttings and planting media were expected to affect the success of plant propagation. This study aims to determine the maturity level of cuttings material that can grow well and deter-mine the type of media that can support the growth of chaya propagation. This research has been carried out from July to October 2022 in an off-campus experimental outdoor facility located in Inderalaya, South Suma-tra. This study was conducted using a randomized block design with 2 factors. The first factor was the level of maturity of stem cuttings material (upper, middle, and basal), and the second factor was the type of growing medium (control, chicken manure, and cow manure). The results showed that the use of cuttings from the mid-dle and basal has a better percentage of growth ability than the upper cuttings. Chaya plants used basal stem cuttings exhibited slower shoot grow but produced higher number of leaves, greater leaf area, canopy area, and biomass. The use of cow manure in a mixture of growing medium gave the best results on growth of chaya plants.

Abstract

Red chili (Capsicum annuum L.) is one of important types of vegetables and also has many varieties that have distinctive colors and shapes, chili is also considerd as one of vegetable that has high economic value. Chili is usually consumed in from of fresh, dried and processed as vegetables and also seasonings, in addition to functioning as a food flavor enhancer. Many obstacles faced by farmers in chili cultivation are plant disturbing organisms such as pests and diseases. Some important pests that commonly attack chili plants are fruit flies (Bactrocera spp), armyworms (Spodoptera litura) and aphids (Aphis gossypii). The purpose of this field practice was to determine the diversity of arthropods and the intensity of pest attacks in Pagaralam City on ten chili fields with different ages. This field practice is expected to provide information about arthropod diversity and attack intensity, especially to farmers as the main actors in agriculture. This insect observation method is carried out using the Diagonal sampling method, Scan sampling (Visual observation) and observing the intensity of the attack. The results of the observations obtained are that the chili farmers have carried out the concept of integrated pest management, but they are not aware of it, and the pests obtained in the field are fruit flies (Bactrocera spp), armyworms (Spodoptera litura) and aphids (Aphis gossypii), and for arthropod diversity it varies on each land.

Abstract

Environmental growth will have an impact on plant morphology. This condition also involves shading and nutrient availability for Brazilian spinach as an introduced leafy vegetable. The study aimed to evaluate Brazilian spinach growth and yield on different shading intensities and organic fertilizers. The study adopted a split-plot design with artificial shading intensities (0%, 50%, and 70%) as the main plot and the type of organic fertilizer (guano, vermicompost, liquid organic fertilizer) as the subplot. The results showed that Brazilian spinach could adapt to canopy areas. However, the Brazilian spinach growth was dominant in a no-shade environment (S0). It was evident by shoot fresh weight (SFW), stem dry weight (SDW), branch dry weight (BDW) and leaf dry weight (LDW). Guano fertilizer (F1) was an organic fertilizer that increased the observed variables, including canopy growth, nutrient and water absorption ability and absolute growth of Brazilian spinach. Although the shoot-root ratio for each single treatment did not show a significant effect. There was a significantly interaction between shade and organic fertilizer in Brazilian spinach growth for all morphological traits including shoot-root ratio. Generally, leaf growth was a positive correlation to stem (R2= 0.9918), branches (R2= 0.7258) and shoots (R2=0.9105). In conclusion, the most suitable growing environment for Brazil spinach growth and yield is in no-shading areas, while guano fertilizer application is recommended to be selected to enhance Brazil spinach growth and yield.
