Abstract

The use of cocoa pod husk biochar and various biological agents in the planting medium significantly increased the growth of cocoa seedlings. The research was conducted using a Randomized Block Design (RBD) with a Split Plot pattern.  The main factors consisted of 2 (two) treatment levels, namely: B0 (without biochar of cocoa pod skin) and B1 (15 g of cocoa pod husk biochar), while the child factors consisted of 4 (four) treatment levels, namely: A0 (without biological agents), M (arbuscular mycorrhiza 15 g), MR (arbuscular mycorrhizae 15 g + 15 ml rhizobacteria) and MT (arbuscular mycorrhizae 15 g + Trichoderma sp. 15 ml), so that there are 8 (eight) treatment combinations, namely: B0A0 (without biochar and without biological agents), B0M (without cocoa pod husk biochar + arbuscular mycorrhizae 15 g), B0MR (without cocoa pod husk biochar + arbuscular mycorrhizae 15 g + rhizobacteria 15 ml), B0MT (without cocoa pod husk biochar + arbuscular mycorrhiza 15 g + Trichoderma sp. 15 ml), B1A0 (cocoa pod husk biochar 15 g + without biological agents), B1M (cocoa pod husk biochar 15 g + arbuscular mycorrhizae 15 g), B1MR (cocoa pod husk biochar 15 g + arbuscular mycorrhizae 15 g + rhizobacteria 15 ml), B1MT (cocoa pod husk biochar 15 g + arbuscular mycorrhizae 15 g + Trichoderma sp. 15 ml), which repeated 4 (four) times so that there are 32 experimental units.  The variables observed were plant height, total leaf area, number of leaves, root length, root dry weight, shoot dry weight. The results showed that the interaction of cocoa pod husk biochar and biological agents had no significant effect on the growth of cocoa seedlings. Application of cocoa pod husk biochar 15 g/polybag had a significant effect in increasing the growth of cocoa seedlings compared to without cocoa pod husk biochar, while the application of biological agents was shown in the 15 g arbuscular mycorrhizae + Trichoderma sp. 15 ml / polybag has a very significant effect on increasing the growth of cocoa seedlings compared to without biological agents.Keywords:  Biochar, arbuscular  mycorrhizal, nutrient uptake.

Abstract

The experiment was carried out to characterize the ability of rhizobacteria isolated from the rhizosphere of healthy lowland rice in dissolving phosphate or fixing nitrogen.  The research was conducted from February to June 2011 at Agronomy Laboratory, Agriculture Faculty, Halu Oleo University. The experiment was arranged based on descriptive methods. Overall, the number of isolates characterized were 40 isolates.  The results of the isolate characterization were documentated with specific indicators (eg. the ability to dissolve phosphate in the form of halo/clear zone). The research indicated that most of these isolates had the ability to dissolve phosphate and fix nitrogen.  Isolates PKNW 6, PKMN 7,  PKNS 3, PKNS 9 and PKNW 4 showed better ability in dissolving phosphate and fixing nitrogen than other isolates evaluated. Further studies are still needed for the development of the potential isolates as biological agensts or biofertilizer. Keywords: healthy rice rhizosphere, rhizobacteria, fix nitrogen, dissolve phosphate

Abstract

This study aims to investigate the effect of combining Kinetin and IAA on the growth of kepok banana shoots in vitro. The research was conducted at the In Vitro Laboratory, Agrotechnology Unit, Faculty of Agriculture, Halu Oleo University, from January to April 2023. The study utilized a Completely Randomized Design (CRD) with six treatments: P1 = (Kinetin 1 mg L⁻¹ + IAA 2 mg L⁻¹), P2 = (Kinetin 3 mg L⁻¹ + IAA 4 mg L⁻¹), P3 = (Kinetin 5 mg L⁻¹ + IAA 6 mg L⁻¹), P4 = (Kinetin 2 mg L⁻¹ + IAA 1 mg L⁻¹), P5 = (Kinetin 4 mg L⁻¹ + IAA 3 mg L⁻¹), and P6 = (Kinetin 6 mg L⁻¹ + IAA 5 mg L⁻¹). Each treatment had five replicates, resulting in 30 experimental units, with four Kepok banana shoot explants per culture bottle. The observed variables included shoot emergence time, number of shoots, shoot length, and shoot growth percentage. Results indicated that the combination of Kinetin and IAA concentrations significantly affected the number of shoots and shoot emergence time and shoot length, but did not significantly affect the shoot growth percentage. The best treatment was P2 = (Kinetin 3 mg L⁻¹ + IAA 4 mg L⁻¹) for in vitro growth of Kepok banana shoots.

Abstract

Ultisol dry land is characterized by significantly low organic carbon content, an important factor influencing soil water content and physico-chemical dynamics. The addition of N fertilizer dissolved in seaweed liquid extract as an enrichment solution can change the character of biochar. Therefore, this study aimed to analyze the characteristics of cogongrass biochar enriched with dissolved N fertilizer in seaweed extract of different species and assess its impact on soil water content in Ultisol. Urea was used as a nitrogen source, and biochar enriched with N fertilizer dissolved in seaweed liquid extract from Kappapychus alvarezii, Sargassum sp., and Ulva lactuca was tested. Biochar dose used was 20% of soil weight with a 10% extract concentration for each type. Furthermore, five-level treatments were tested in a pot experiment, namely (i) without biochar, (ii) biochar unenriched, (iii) enriched with N fertilizer dissolved in K. alvarezii extract, (iv) enriched with N fertilizer dissolved in Sargassum sp. extract, and (v) biochar enriched with N fertilizer dissolved in U. lactuca extract. Each treatment was repeated three times, following a randomized block design. The results showed that cogongrass biochar enriched with N fertilizer dissolved in seaweed extract had a more amorphous surface morphology structure. The proportion of elements and functional groups in cogongrass biochar changed. Enriched biochar increased Ultisol moisture levels, but water holding capacity and retention were lower than the unenriched sample.

Abstract

The quality of acidic soil is determined by organic C content produced from rice straw biochar in agriculture. In this context, liquid extract from Kappapychus alvarezii (K-sap) is used as a biochar enrichment agent. Therefore, this research aimed to (i) analyze the character of K-sap enriched rice straw biochar with different volumes, as well as (ii) evaluate the impact on soil water holding capacity, size class distribution, aggregate stability index, respiration rate, and acidic soil chemical characters. The treatment tested was the volume of K-sap kg-1 biochar, namely (i) without biochar, (ii) 0 mL, (iii) 500 mL, (iv) 1,000 mL, and (v) 1,500 mL. Each treatment was repeated three times and placed according to a randomized block design procedure. The area covered by K-sap, pore size, and amorphous degree increased while the pore volume of the biochar surface decreased. The addition of 1,000 mL of K-sap kg-1 biochar released a new peak number associated with the aliphatic and aromatic groups. The K-sap enriched biochar increased the proportion of soil aggregate size of 1-2 mm, water holding capacity, carbon storage, pH, total N, available P and K, exchangeable base cations as well as base saturation. Meanwhile, the concentration of Al3+ and H+ were decreased in the acidic soil solution. The results showed that the performance of rice straw biochar, K-sap volumes, soil chemical quality, water holding capacity, and ability to store carbon of the acidic soil was improved by adding K-sap volume.

Abstract

Earthworms as ecosystem engineers can modify the quality of vermibed assembled from mixed soil with organic material in a vermireactor. Various in shapes of the vermireactor are used to produce a vermicast for biofertilizer in agriculture. The objective of this research was to study the vermicast production and its quality produced from a variety of vermireactor shapes. Earthworm (Pheretima sp.) which was applied to the vermireactor consists of: with- and without of earthworms. Three shapes of the vermireactor, namely cylinder, square, and rectangular has been tested. Compost of Chromolaena odorata pruning mixed with soil was used as vermibed. The vermicast process ran until 28 days. The results showed that vermireactor with earthworms which were successfully converted to vermicast was about 49.24% from the vermibed volume, however, no vermicast formed was found from vermireactor without earthworms. The difference in vermicast produced from different vermireactor shapes was not significant. The value of pH, total-N, and C/N ratio among the vermicast was different. The number of the morphological character of bacteria colonies in the vermicast produced from the square vermireactor was the highest, while from cylinder vermireactor was the lowest. We concluded that the quality of vermicast from earthworm (Pheretima sp.) activity was determined by the shape of the vermireactor.
