      Abstract: ABSTRACT            Shallot caterpillar (Spodoptera exigua Hubner.) is a major problem in onion cultivation. Spodoptera exigua can cause yield loss of 45-57% and can cause crop failure. Controls are generally carried out using synthetic insecticides, but the continuous use of synthetic insecticides can have a negative impact on humans and the environment. One alternative control that can be used is a vegetable insecticide with organic solvents from Bintaro leaf extract (Cerbera manghas L.). The study was aimed to obtain the concentration of bintaro leaf extract using an effective organic solvent to kill Spodoptera exigua larvae on shallots. This research was conducted at the Laboratory of Organic Chemistry and Natural Materials, Faculty of Engineering, Laboratory of Plant Pests and Laboratory of Experimental Gardens, Faculty of Agriculture, Riau University from July to September 2021. This research was conducted experimentally using a Completely Randomized Design (CRD) with six treatments and four treatments. replicates to obtain 24 experimental units. The treatments were bintaro leaf extract concentrations of 0%, 0.2%, 0.4%, 0.6%, 0.8%, and 1%. The results showed that a concentration of 1% was an effective concentration in killing Spodoptera exigua larvae of 87.50% with the fastest early death time at 12 hours after application, Lethal time 50 at 53 hours after application, and the highest daily mortality occurred on the third day, namely 35% after 5 days after application.Keywords : Bintaro leaf, Shallot, Spodoptera exigua Hubner

      Abstract: Seedling fall disease caused by the fungus Rhizoctonia solani is one of the limiting factors in the cultivation of mustard plants. This pathogen can attack plants in the nursery as well as after the plants in the field. The aim of this study was to determine the effect of using biological fertilizers Azoto-Trico and KIBPF with different application time intervals on the development of seedling fall disease and the growth of mustard in the nursery. The study used Azoto-Tricho and KIBPF biological fertilizers with application intervals of 2 days, 4 days and 6 days. The results showed that the application of biological fertilizers Azoto-Tricho and KIBPF with different application time intervals had an effect on controlling seedling fall disease and increasing plant height and plant fresh weight. The application of Azoto-Tricho biofertilizer and KIBPF if applied at intervals of 2 days or 4 days or 6 days had the same ability to control seedling fall disease and increase plant height and fresh weight of mustard plants in nurseries.

      Abstract: Broccoli (Brassica oleracea L.) is one of the vegetables that has high selling power and is quite promising for cultivation. This plant can grow in fertile soil conditions, loose and rich in organic matter that is able to meet the nutrient needs of broccoli plants. The fertilization process is very important in determining the quality of cultivated plants. Fertilization using organic fertilizers is believed to be able to produce much higher production than expected by farmers and is environmentally friendly. The application of adding solid and liquid organic fertilizers to broccoli plants is expected to increase growth and production. The research design used was a Factorial Randomized Block Design consisting of two factors. The first factor is doses of solid organic fertilizer which consists of three levels, namely 0%, 25% and 50%. The second factor is doses of liquid fertilizer which consists of four levels, namely 0 ml, 10 ml, 20 ml and 30 ml. The results showed that the addition of solid and liquid organic fertilizers had a significant effect on the parameters of plant height, number of leaves, crop diameter and production of broccoli plants with the highest production in the treatment of 50% solid organic fertilizer with 10 ml of liquid organic fertilizer of 87.4 g.
