Abstract

ABSTRAK Chili (Capsicum annuum L.) is one of the horticultural commodities which is classified as a vegetable and is most widely cultivated in Indonesia. In addition, chilies contain minerals such as iron, potassium, calcium, phosphorus and niacin. Tricho-compost is a fertilizer derived from organic materials containing the antagonistic fungi Trichoderma sp. Tricho-compost as fertilizer is able to provide nutrients in the soil for plants. Plant Growth Promoting Rhizobacteria (PGPR) is a group of soil microorganisms that live and develop well in soils that are rich in organic matter and which are beneficial because they can spur plant growth and production. This study aims to determine the effect of the application of Tricho-compost and PGPR (Plant growth promotion rhizobactery) biological agents on the vegetative growth of chili plants. This research was conducted at the green house of the Faculty of Agriculture, Sam Ratulangi University (UNSRAT) Manado. The study lasted for 3 months using RAK (randomized block design) with 4 treatments, namely Control (NPK), Tricho-compost, PGPR (Plant Growth Promoting Rhizobacteria) and Tricho-compost added with PGPR (Plant Growth Promoting Rhizobacteria). Observation of growth parameters in the form of plant height, number of leaves, number of branches and stem diameter. Growth is carried out every week and starts at 2 week after transplanting until the plants are 2 months old. The results showed that the application of Tricho-compost and PGPR treatments given together gave the largest number of branches, number of leaves and stem diameter, while the parameters of height the largest plants were produced in the Tricho-compost treatment, although sta

Abstract

ABSTRACTGolden snail (Pomacea canikulata L.) or also known as mulberry snail is one of the main pestsof rice plants in North Sulawesi, including in the City of Tomohon. This golden snail pest likesyoung rice plants with the intensity of damage varies from 10-100% depending on the level ofpopulation on each land. This pest destroys plants by grating plant tissue and eating it. In responseto help the problems faced by farmers, research has been carried out on the population of thegolden snail pest (Pomaceacaniklata L) in bait and traps on lowland rice plants (Orzya sativa L).The purpose of this study was to determine the effect of the use of papaya leaf baits and watertrench traps on the population of golden snail pests on lowland rice plants. The study wasconducted in Taratara 1 Village, West Tomohoon District, Tomohon City. The duration of thestudy is approximately four months, which took place from March to May 2020. The researchmethod was carried out by quantitative descriptive methods with direct experiments in the field.This experiment uses two lowland rice fields consisting of bait and trap. Observations were madeat the age of plants 21 days after planting, 28 days after planting, and 35 days after planting. Theresults of the research on the treatment of bait using papaya leaves an average of 24.8 individuals/ m2 and on the treatment of traps using an average water trench of 31.4 individuals / m2. Thepopulation of golden snail pests in both treatments decreased from plants aged 21 days afterplanting to 35 days after planting. The age factor in plants can increase the height of golden snailpests. Gold snail can easily attack plants by grating the plant tissue and eating it. Because thestructure of the stems, stems, and leaf blades in the plant is still young. Both treatments contributeto positive results, so that further research is needed by combining bait and trap treatments on alarger scale and can be integrated with other environmentally friendly control methods.

Abstract

ABSTRACTP. blanchardii is the major insect pest. Adult and nymph insects, suck nitrogen andmacro elements in leaves. In high-level attacks, P blanchardii causes major damage in the formof decreased P. blanchardii attacks causing date palms to cover a very thick leaf surface so thattranspiration, respiration and photosynthesis are disturbed, causing leaf wilt, inhibiting growthand reduction of mature tree yields and death of trees young. The research was carried out fromNovember 2019 to February 2020 at the Green House of Balit Palma Manado, North Sulawesi.The research method used was RAK with 7 treatments in the form of date varieties and 3replications. This research was conducted by means of quantitative descriptive data collectionmethods or primary data which was carried out directly in the field and saw firsthand P.blanchardii attacks on palm leaves. The things that were observed in this study were, symptomsof P. blanchardii pest attack on date palm leaves, attack on 5 leaflets and 10 leaflets, and 7varieties of date palm attacks per tree. The results showed that the percentage of attacks by P.blanchardii on dates was the highest attack on the Fard variety 55.41% and the lowest attackpercentage was the 9.32% Barhee variety. So it is necessary to do further research on P.blanchardii pests and also control using natural enemies against P. blanchardii pests on datepalms in Indonesia.Keywords: attacks, P. blanchardii, date palm variety
