Abstract

Mutation induction by colchicine is one method to improve plant genetic diversity (polyploidy). This study aims to 1) obtain growth regulators composition suitable in inducing callus, 2) obtain the LC50 value in callus of P. amboinicus, 3) to determine the effect of colchicine on callus growth, 4) to get shoots (putative mutant) varian, regenerating from indirect organogenesis (callus) in MV1. The study is conducted at the Laboratory of Agricultural Seed Management, Plantation Research, and Development Center from June 2018 to June 2019. The study uses a complete randomized design with four treatments and three replications. Explants use ware the nodes. Callus induction uses MS0 medium with 0.5 ppm 2.4-D, 2 ppm 2.4-D, 0.5 ppm 2.4-D + 1 ppm BAP, and 0.5 ppm 2.4-D + 0.5 ppm TDZ treatment. Mutation induction was performed using colchicine concentration at 0%, 0.02%, 0.04%, and 0.06% treatments. The regeneration media is an MS0 medium. The results show the best combination of plant growth regulators to induce the callus is 0.5 ppm 2.4-D. The LC50 colchicine concentration is at 0.0275%. However, this phenotype is reversible. An additional subculture period is required to move to normal morphology

Abstract

A high population of Crocidolomia pavonana larvae reduces Brassicaceae crop productivity. To control the pest population, mixed plant extract as botanical insecticides is one of the alternatives. The purpose of this research is to evaluate the joint action between mixed extracts of Azadirachta indica and Barringtonia asiatica seed extracts against C. pavonana larvae and the effect on feeding behavior. The seeds are extracted with ethanol using the maceration method. Bioassays are conducted by a feeding method. Each level of concentration tested and controlled is repeated five times. The concentration-mortality relationship is analyzed using probit. Feeding behavior assayed by choice and no-choice at concentrations equivalent to LC25, LC50, and LC75. The results show the mixture of A. indica and B. asiatica seed extract at a ratio of 3:2.3 has a strongly synergistic action with an LC50 of 0.04% and a combination index of 0.27. The extract mixture at a concentration of 0.02-0.08% is reduced feeding activity 77.16-92.84%. Further research is needed to evaluate the extract mixture in the field.

Abstract

 This research aims to determine the best pH media for the production of Pseudomonas fluorescens P20 raw secondary metabolites, its effect on controlling damping-off, and on cucumber seedling growth. In vitro test uses completely randomized design with four replicates and seven treatments consisted of pH 5.0; 5.5; 6.0; 6.5; 7.0; 7.5; and 8.0. In planta test uses a randomized block design with three replicates and ten treatments consisting of control, mancozeb 80%, and raw secondary metabolites with pH 7.0 and 7.5, and 4 concentration levels, i.e., 5, 10, 15, and 20%. Variables observe population density, inhibition ability, protease and chitinase qualitatively, germination ability, incubation period, disease incidence, the area under disease progress curve (AUDPC), crop height, number of leaves, root length, and crop fresh weight. The result shows that the best pH for the production of raw secondary metabolites is 7.0, indicated by population density as 5.68 × 1024 cfu/ml, inhibition ability as 50.8%, and the best protease and chitinase qualitatively. Application of the secondary metabolites on pH 7.0 could suppress disease intensity, incubation period, and AUDPC as 66.67, 77%, and 0%-day, respectively, and increase crop height, the number of leaves, root length, and crop fresh weight as 57.65, 37.19, 63, and 74%, respectively.

Abstract

The objective of this study was to examine the effects of four different elevations on Acacia mangium volume in Bintulu, Sarawak. A total of 60 felled trees of A. mangium were used to develop a volume equation by measuring the volume at four different classes of elevation. The study of stand volume estimation in Malaysian plantations, particularly in Bintulu, is sparse. To get the average cross-sectional area, the volume of each tree in each part of the felled trees was estimated using Smalian’s and Newton’s formulas. Four equations were developed in this study to predict the volume from the diameter and analyze the effect of elevation on tree volume. According to the regression analysis, there was a significant relationship between the volume and diameter for each slope steepness. The Very Slope site had the highest volume with an R² value of 0.948 for the model’s fit, which revealed that 94.8% of the data could be evaded. Volume estimation using the regression model can be used to determine and categorize according to its class of elevation, and there is an effect of elevation on standing volume. A. mangium has better growth performance in a very slope area in terms of tree volume compared to different elevations.

Abstract

Soil health decreases and residual pesticides increase due to the application of inorganic fertilizers and pesticides continuously during the cultivation of crops. The effect of 12 hours or 24 hours soil submersion and chicken litters or zeolite application before planting on residual pesticides in soil and bulbs of shallots (Allium ascalonicum L.) are studied. Samples of soils and bulbs have proceeded after shallot cultivation conducted in Brebes, Indonesia. Then organophosphate residues in the samples are analyzed using gas chromatography in the Laboratory of the Indonesian Agricultural Environment Research Institute, Bogor. The data are compared to the standard of maximum residue levels (MRL) of pesticides in agricultural products. Results show that residual pesticides in treated soils are below the detection limit of the GC equipment, except malathion is detected with values ranging from 0.039-0.050 ppm. However, residual organophosphate pesticides in the bulbs are mainly below the maximum residue levels. The only exception is chlorpyrifos which has a value above the maximum residue levels of pesticides (0.076 ppm). Farmers should be educated in integrated pest management and applying synthetic pesticides as the last option for controlling pests and diseases.

Abstract

A field experiment was conducted at Kediri, East Java, to examine the influence of row spacing on the yield of five promising clones from August 2018-June 2020. The investigation was of a Split-Plot design with three replications. The main plot consisted of three planting arrangements: SR, single row spacing at 110 cm, DR1, double rows spacing 50+135 cm, and DR2, double rows spacing 50+170 cm. Sub-plots consisted of five promising clones and one check variety: MLG 5, MLG 9, MLG 14, MLG 52, MLG 55, and PS 881. The results suggest no overall significant effect of planting arrangement on sugar yield, though clones may vary. There are significant differences in yield between some clones. Wider rows, DR2, show the highest yield in tonnes of cane per hectare (TCH) in PC (153.94 t/ha) with a slight decrease (14%) in RC-1 due to reduced plant population. Sugar yield in tonnes of sugar per hectare (TSH) in various planting arrangements ranges from 12.26-13.99 t/ha in PC and 10.68-11.93 t/ha in RC-1. MLG 9 can be released as a new variety with high cane and sugar yields.

Abstract

Varieties with high yield stability are required to increase the yield. This study examines the strength and adaptability of seven Bambara groundnut lines in three areas. The seven lines used are CCC 1.6, PWBG 6, PWBG 521, SS 342, SS 242, BBL 11, and TVSU 86 as checks. The research sites are Brawijaya University Experimental Station, Farmer field in Madiun and Indonesia Legumes, and Tuber Crop Research Institute (ILETRI) Research Station. Research is conducted from February to October 2020. The study used a randomized block design with three replications. The Eberhart-Russel and FinlayWilkinson methods were used to analyze stability and adaptability. The Genotype x Environmental interaction (GxE) results of the 7 Bambara groundnut lines are at 50% flowering time, seed weight per plant, 100-seed weight, yield, and harvest age. The stability and adaptability analysis shows that BBL 1.1 line is the variety with an earlier harvest period, highest yield potential, good stability, and wide adaptability. The CCC 1.1, PWBG 6, PWBG 5.2.1, and SS 2.4.2 production lines are stable in all experimental environments but low productivity. The SS 3.4.2 is suitable for planting in a production environment. TVSU 86 is ideal for producing in marginal habitats such as drought conditions.

Abstract

Multi-nutrients deficiency of soil in southwest Ethiopia is among the primary constraints for the very low productivity of potatoes (Solanum tuberosum L.). The combined use of organic and inorganic fertilizers is vital for resolving the common productivity issue. Thus, experiments were performed on potato variety “Belte” in Masha district, southwestern Ethiopia, in both Belg (February to May) as well as Meher (June to October) seasons of 2019 to evaluate the potato response to the vermicompost, mineral phosphorus, and nitrogen’s integrated applications. The experiment had three vermicompost rates with the factorial combination (2.5, 5, 7.5 t/ha) and three recommended rates inorganic NP’s 25%, 50% and 75% (124 kg N/ha and 103 kg P2O5/ha) fertilizer. Results have discovered that 75% inorganic NP and 7.5 t/ha vermicompost’s combined application significantly increase total tuber yield, marketable tuber yield, and individual tuber weight, giving the maximum net benefits and marginal return rate. Thus, it has been discovered from this work that for potato production at Masha area, 7.5 t/ha vermicompost with inorganic NP’s 75% recommended dose’s combined applications are best-integrated nutrient management options.

Abstract

The study aims to observe coconut shell liquid smoke as a bio-fungicide in controlling F. oxysporum growth. The treatment was applied on sample i.e., coconut shield liquid smoke as a bio-fungicide, compared with a chemical fungicide as a positive control, and without treatment as a negative control. The direct observation was conducted for four weeks, with treatment application every seven days. The analysis of variance test shows the difference of three treatments in controlling the F. oxysporum growth for each observation period. Still, it has no difference in average in fungal growth after treatment. According to the results of weekly observations, coconut shell liquid smoke biofungicide reduces the disease severity on the tapping fields infected by F. oxysporum in the range of 13-21%, whereas chemical fungicide reduces the disease severity in the range of 1-10%. In conclusion, the ability of coconut shell liquid smoke bio-fungicide to control is relatively shorter compared to chemical fungicide. Based on the inhibition ability of coconut shield liquid smoke, it is recommended that utilize various grades of coconut shell liquid smoke as a comparison.

Abstract

Indonesia is a major producer of palm oil. Consequently, the use of chemical fertilizers has become more extensive. Microalgae represent a potential alternative for enhancing and protecting crops based on their cell elements. This study applies dry biomass or liquid culture formulation of the green microalgae Haematococcus pluvialis to the rhizosphere of oil palm pre-nursery as a biofertilizer. Soil application of microalgae biomass of 0.5 g/l (MA) or liquid culture of 10% (v/v) (BCMA) is carried out to assess its effects on 4-months-old oil palm at the nursery stage. The compatibility test between microalgae and bio fungicide agents in agricultural practices, Trichoderma spp., is also tested on both microalgae formulations. The result shows that both microalgae biomass and liquid culture, alone or combined with Trichoderma spp., give a better growth performance to the oil palm. The application of MA and BCMA result in a maximum increment of plant height, leaves count, and chlorophyll content. Furthermore, the application of BCMA gives better oil palm growth performance, which may probably be influenced by the accessibility of nutrients for microalgae growth. The study reveals that soil application of microalgae as biofertilizers can improve oil palm growth performance.
