Abstract

Arthropods, the largest taxon in the animal kingdom, serve as indicators of ecosystem balance. This study aimed to assess the diversity, evenness, and dominance of arthropods in corn (Zea mays L.) with and without botanical insecticide application. The research was conducted in Oloboju Village, Sigi Biromaru District, Central Sulawesi, from September to November 2022. The study utilized pitfall traps, light traps, and sweep nets to observe arthropods. The results indicated higher arthropod diversity without insecticide application: 4 classes, 14 orders, 44 families, 57 species, and 1,112 individuals, compared to 4 classes, 14 orders, 39 families, 49 species, and 891 individuals with insecticide. The diversity index and evenness index were higher without insecticide (3.04 and 0.75) than with insecticide (2.81 and 0.72). Both treatments had low dominance index values (0.10 and 0.12), suggesting no single species was dominant.

Abstract

This study aimed to evaluate the drought tolerance of different local upland rice cultivars under various watering intervals. The research was conducted at the Greenhouse of Plant Breeding, Faculty of Agriculture, Tadulako University, Palu, from June to August 2020. A two-factorial completely randomized design was used. The first factor was the rice cultivar, comprising three types: Pulu Tau Leru, Jahara, and Uva Buya. The second factor was the watering interval, with five level watering: daily (P1), every other day (P2), every two days (P3), every three days (P4), and every four days (P5). This resulted in 15 treatment combinations, each replicated four times, totaling 60 experimental units. Observed parameters included plant height, leaf length, leaf curl, and number of tillers. The results indicated that the growth of the different local upland rice cultivars was significantly affected by the watering intervals across all observed parameters.

Abstract

The excessive use of non-organic fertilizers can lead to soil degradation. To address this issue, organic fertilizers, such as goat manure, can be used as an alternative to enhance soil fertility and improve crop production. This study aimed to determine the effective dosage of goat manure fertilizer on the growth and yields of soybean plants (Glycine max L. Merrill). The research was conducted in a screen house at Tadulako University, Palu, from November 2020 to 2021. The study used a Completely Randomized Design (CRD) with one factor: the dosage of goat manure. The treatments included: K0 (no fertilizer added, control), K1 (7 t/ha or 35 g/polybag), K2 (8 t/ha or 40 g/polybag), K3 (9 t/ha or 45 g/polybag), and K4 (10 t/ha or 50 g/polybag). The results of this study are expected to provide insights into optimal goat manure application rates for sustainable soybean cultivation.

Abstract

Lembah Palu shallot variety is a prominent commodity in Central Sulawesi, known for being a key raw material in the onion industry a regional trademark of Palu city. To enhance the shallot productivity, one effective strategy is the intercropping of shallots with chili plants, particularly with the F1 variety 'Dewa'. This study aimed to evaluate the growth and yield of Lembah Palu shallots when planted at different intervals relative to chili plants used as border crops. The research was conducted in Oloboju Village, Sigi Biromaru District, Central Sulawesi Province, from September to November 2019. The study employed a Randomized Block Design (RBD) with treatments based on different planting times of the shallots relative to the chili plants: T1 (simultaneous planting with chili), T2 (7 days after chili planting), T3 (14 days after chili planting), and T4 (21 days after chili planting). Each treatment was replicated four times, resulting in a total of 16 experimental plots. The results indicated that the different planting times of Lembah Palu shallots intercropped with chili plants did not significantly affect plant height, leaf number, or fresh root weight. However, significant effects were observed on the bulbdiameter and yield of Lembah Palu shallots.

Abstract

The objective of this research was to investigate the ability of Trichoderma harzianum to suppress the growth of Fusarium oxysporum f.sp. cepae, which causes damage to red onion crops. The study was conducted in Sidera Village, Sigi Biromaru Subdistrict, Sigi Regency, Central Sulawesi Province, and at the Plant Disease Laboratory, Faculty of Agriculture, Tadulako University, Palu, from August to December 2021. A randomized complete block design (RCBD) was employed, with six treatments: P1 (10-3 dilution, immersion), P2 (10-3 dilution, immersion and one foliar application), P3 (10-3 dilution, immersion and two foliar applications), P4 (10-6 dilution, immersion), P5 (10-6 dilution, immersion and one foliar application), and P6 (10-6 dilution, immersion and two foliar applications). Each treatment was replicated three times, resulting in 18 experimental units. The results indicated that the combination of immersion and foliar application at a 10-3 concentration was effective in suppressing the pathogen's growth and reducing moler disease incidence. Moreover, the 10-3 concentration was more efficient in enhancing onion growth and yield compared to the 10-6 concentration, likely due to its faster or more targeted application.

Abstract

The objective of this study was to investigate the response of sweet corn growth and yield to the application of rice husk biochar and NPK fertilizer, and to determine the optimal combination of biochar and NPK dosages that enhance sweet corn growth and yield. The study was conducted in Makmur Village, Palolo Subdistrict, Sigi District, Central Sulawesi, Indonesia from January to April 2022. A two-factorial randomized block design (RBD), namely biochar dosage and NPK fertilizer dosage, was employed. Each factor had three levels, and each treatment combination was replicated three times. The results showed that the interaction between NPK fertilizer and rice husk biochar was significant only for ear length and ear weight, regardless of ear type (tasselled or untasselled). The application of rice husk biochar significantly reduced the need for NPK fertilizer in sweet corn cultivation.

Abstract

This study aimed to evaluate the effect of different growing media on the growth and yields of tomato plants (Solanum lycopersicum). The experiment was conducted at the Academic Farm of the Faculty of Agriculture, Tadulako University, Palu, Central Sulawesi, from March to May 2021. A Randomized Complete Block Design (RCBD) was employed with six different treatments: P0 (Control, soil only), P1 (Soil + Rice Husk Charcoal 1:1), P2 (Soil + Rice Husk Charcoal 1:2), P3 (Soil + Rice Husk Charcoal 1:3), P4 (Soil + Rice Husk Charcoal 3:1), and P5 (Soil + Rice Husk Charcoal 3:2). Each treatment was replicated four times, resulting in a total of 24 experimental units, with each unit containing three plants, amounting to a total of 72 plants per polybag. The results demonstrated that the P3 treatment (Soil + Rice Husk Charcoal 1:3) significantly enhanced the growth and yields of tomato plants. This treatment yielding the highest performance: an average plant height of 99.44 cm, 81.58 leaves, 12.78 branches, 11.56 fruits per plant, and an average fruit weight of 363.12 g. These findings suggest that the P3 growing medium is particularly effective in promoting the optimal growth and productivity of tomato plants.
