Abstract

This study aims to determine the effect of various doses of bokashi fertilizer on the growth response and production of local Konawe corn plants and to determine which treatment has the best effect on the application of various doses of bokashi fertilizer on the growth response and production of local corn plants in Konawe. This research took place at the Field Laboratory of Experimental Gardens II, Faculty of Agriculture, Halu Oleo University, Kendari. From January to March 2021. This study used a randomized block design consisting of 5 levels of treatment, namely control without bokashi fertilizer (B0), bokashi fertilizer 5 t ha-1(B1), bokashi fertilizer 10 t ha-1 (B2), bokashi fertilizer 15 t ha-1 (B3), bokashi fertilizer 20 t ha-1 (B4). Each treatment was repeated 3 times so that there were 15 experimental units. The results showed that the observed variables had a very significant effect on plant height, stem diameter, number of leaves, leaf area, cob weight, ear length (cm), wind-dried shell weight, weight of 100 seeds and productivity. The best treatment was obtained at doses of bokashi fertilizer of 20 t ha-1 (B4) and 15 t ha-1 (B3).

Abstract

This study aimed to evaluate the effect of clove oil to control pathogens associated with tomato plants in screen houses. The study was carried out using a completely randomized design (CRD) with 5 treatments repeated 3 times and each treatment consisted of 3 plants for a total of 45 plants, the treatments given were P0 (without application), P1 (pathogenic fungus Sclerotium sp. without clove oil application). , P2 (pathogenic fungus Sclerotium sp. with clove oil application), P3 (pathogenic fungus Helminthosporium sp. without clove oil application), P4 (pathogenic fungus Helminthosporium sp. clove oil application). The variables observed were plant height, stem diameter, number of branches and disease severity of tomato plants. The results showed that clove oil was able to increase plant growth as indicated by the highest average height and diameter of 18.61cm and 0.31cm, respectively. Clove oil application also suppressed the development of the pathogen Sclerotium sp. As indicated by the average incubation period and disease severity 18.67 days and 6%, respectively.

Abstract

Peanut (Arachis hypogaea L.) is an agricultural commodity that acts as a protein and vegetable oil source, but in Southeast Sulawesi, its productivity is still relatively low. This study aims to determine the effect of giving bokashi tofu waste and phosphate fertilizer on the growth of peanut plants. The research was conducted at the Experimental Field Laboratory II, Faculty of Agriculture, Halu Oleo University, Kendari, from June to September 2021. The study used a factorial randomized block design consisting of bokashi tofu waste with four treatment levels, namely 0, 5, 10, and 15 tons per hectare, and phosphate fertilizers with three treatment levels, namely 0, 100, and 200 kg per hectare. The total combination of treatments was 12, with three replications. Observational data were analyzed using analysis of variance and UJBD. The analysis results showed that the interaction of bokashi with tofu waste and phosphate fertilizer had a significant effect on plant heights 28 and 35 DAP, stem diameter 21 DAP, leaf area 14, 21, and 28 DAP, and root loss ratio. Bokashi tofu waste independently significantly affected plant height, stem diameter 28 DAP, leaf area, and root loss ratio. Phosphate fertilizer independently significantly affected plant height at 28 and 35 DAP, leaf area at 14 and 21 DAP, and root loss ratio. The combination of 15 tons of tofu waste bokashi per hectare and 100 kg of phosphate fertilizer per hectare was the best treatment for increasing the growth of peanut plants.

Abstract

Nickel mining activities in Southeast Sulawesi have triggered the physical, chemical and biological degradation of soil. Therefore, the application of organic amendment was an alternative solution to restore the degraded soil. This research aimed to study the effect of ameliorant on soil chemical properties and the effect of ameliorant on yield of cayenne pepper on ex-nickel mining soil. This research was conducted on Field Experimentation Station. Faculty of Agriculture Halu Oleo University, from January to April 2021. This study was carried out using a Randomized Block Design (RBD), which consists of 4 treatments namely without ameliorant (B0), cow manure 60  (B1), biochar husk 60  (B2), cow manure + biochar husk (1:1) 60  (B3) with 4 replications. The results showed that overall ameliorant had an effect on increasing soil pH, Organic-C, available-P, available-K, and Cation Exchange Capacity. Soil pH increased from 4.32 to 6.1, C-organic increased from 0.78% to 1.89%, available-P increased from 3.87ppm to 16.87ppm, available-K increased from 10 mg 100g-1 to 40 mg 100g-1, Cation Exchange Capacity increased from 0.1 me 100g-1 to 75.11 me 100g-1, while total-N increased from 0.21% to 0,38%. Application of 60  (B1) of cow manure increased the plant height and the number of leaves by 29.65 cm and 51,25 respectively.

Abstract

Excessive use of insecticides will have a negative impact on the development of ecosystem and the environment, kill non-target insects and kill natural enemies and pollinating insects. One solution to control pests on chili plants is to engineer ecology using refugia plants. Kenikir is a refugia plant that plays an important role in increasing the population of useful insects such as predators and pollinators. This study aims to determine the effect of flower color of kenikir plants on insect diversity in chili plants (Capsicum annum L.). This research was observed on kenikir plants planted around chili plants with the color treatment of kenikir flowers, namely yellow kenikir (C1), orange kenikir (C2) and pink kenikir (C3). The treatment was repeated 6 times so that there were 18 units of observation plots. The variables observed were the number of insect species and their roles, diversity index, species dominance index and evenness index. Observational data were analyzed by simple tabulation to see differences between tretments. The results showed that there were various types of insects that landed on the kenikir flower in different flower colors, but the diseversity index value is in the low category or ≤ 2. The highest index value of diversity and insect population was obtained in the treatment of yellow flowers, then orange and the lowest was in pink flowers.
