Abstract

The mass propagation of coffee plants requires seeds with high-viability characterized by good germination and germination growth. One way to increase the viability of coffee seeds is the provision of Gibberellic acid (GA3). This study aims to determine the effect of several concentrations of GA3 on the viability of Catuai variety of Arabica coffee. The experiment used a completely randomized design (CRD). Treatment with Control and 5 levels of GA3 concentration, namely 0 (Control), 100, 200, 300, 400 and 500 ppm respectively where coffee seeds were soaked for 24 hours before being germinated. The results showed that the concentrations of 300 and 200 ppm GA3 showed the best results for germination percentage and rate Germination, however, did not appear to have a significant effect on the root and hypocotyl length.

Abstract

The nickel (Ni) content in a post-mining soil of Pomalaa mines reached 14,200 mg.kg-1 and became a limiting factor in the plant growth process. A Ni reduction in the soil by using phyto-accumulator such as Jack bean (Canavalia ensiformis L.) can be improved by combining it with arbuscular mycorrhizal (AM) fungi. The purpose of this study was to determine the effect of the mycorrhizal fungus Acaulospora sp. on the efficiency of Ni reduction by C. ensiformis. This experiment was carried out by using a randomized block design with three different treatments, include: 1) C. ensiformis without Acaulospora sp. inoculation (negative control), 2) C. ensiformis inoculated with indigenous Acaulospora sp. and 3) C. ensiformis inoculated with non-indigenous Acaulospora sp. The study was conducted in the nursery that belongs to PT. Vale Indonesia Tbk., Sorowako, South Sulawesi, Indonesia. The results showed that highest nickel accumulation was found in the root inoculated with indigenous Acaulospora sp. (9500 mg.kg-1), followed by stem (1400 mg.kg-1), leaf and pod (1300 mg.kg-1), seed (1200 mg.kg-1), and flower (1100 mg.kg-1). This study indicates that application of the indigenous Acaulospora sp. can improve C. ensiformis efficiency to reduce Ni content at Sorowako post-mining area.

Abstract

The study was conducted to determine the effect of weed management level on the abundance of insect natural enemies in cabbage fields. Two levels of weed management were applied in the field, namely with and without herbicide application in two growers’ cabbage fields in Malino, South Sulawesi, Indonesia. Results demonstrated that insect natural enemies were more abundant in the field without herbicide application than those in the field with herbicide application. Five species of predatory insect species were collected from both fields, anmely Solenopsis sp., Ophionea sp., Euborellia sp., Cicindella sp., and Paederus fuscipes. The herbicide and its surroundings were kept weed-free during the growing season. Four most abundant weed species were found in the field without herbicide treatment including Nasturtium indicum (Brassicaceae), Galinsoga parviflora (Asteraceae), Ageratum conyzoides (Asteraceae) and Cleome rutidospema (Capparidaceae).

Abstract

Mycorrhizal fungi that are capable of adapting and resistant to heavy metal contaminated environments have received special attention for phytorhizoremediation researchers. The aim of the study was to explore native mycorrhizal fungi from areas contaminated with heavy metals to be used as starter biological agents in the phytorhizoremediation program. This research was carried out in two phases, i.e. rhizosphere sampling of Polypodium glycyrrhiza, Sumasang sp (local name) and Spathoglottis plicata at coordinates 2O31'57,6"S and 121O22'50,7"E. Rhizosphere of Chromolaena odorata, Melastama affine and Nephrolepis exaltata at coordinates 2O31'53,5"S and 121O22'35,4"E, Sorowako, Indonesia; While the other phase is isolating and identifying mycorrhizal spores in the Microbiology Laboratory, Research and Development Center for Environment and Forestry in Makassar, Indonesia. The results showed that be discovered three genus of mycorrhizal fungi were able to adapt and resistant in areas contaminated with Cr, Co, and Cu, i.e. 44.44% to 75.86% Acaulospora sp; 9.52% to 44.44% Gigaspora sp, and 3.38% to 19.05% Glomus sp.  which could be used as source of inoculum in Phyto-rhizoremediation program.   We recommend using native mycorrhizal fungi combined with endemic plant of location to rehabilitation heavy metal contaminated soils.

Abstract

The armyworm Spodoptera frugiperda, which damages corn plants, is one of the invasive pests. The armyworm S. frugiperda damages corn plants by eating leaf tissue from one side so that the remaining epidermal tissue then makes holes in the leaves and eats from the edge of the leaf to the inside, which causes perforation in the leaves. Control efforts using insecticides have not been practical due to the feeding behaviour of the second and third instar larvae that settle on the inside of the leaves under protected conditions. Therefore, it is necessary to carry out other control techniques that can suppress the development of environmentally friendly S. frugiperda by considering economic and ecological aspects, namely biological control. Biological control optimizes the role of natural enemies as biological control agents in efforts to manage pest populations which are part of the chain in agroecosystems. Utilization of natural enemies, parasitoids, predators, and pathogen, can suppress the development of the S. frugiperda pest in corn, reducing the use of synthetic pesticides. Natural enemies of S. frugiperda include the egg parasitoid Telenomus sp. and Trichogramma sp.; larva parasitoid Glyptapanteles creatonoti (Viereck), solitary larval parasitoid Campoletis chlorideae Uchida, and parasitoid larvae of the order Hymenoptera: Ichneumonidae: Ichneumoninae and G. creatonoti. as well as an entomopathogenic species, Nomuraea rileyi (Farl.) Samson. Natural enemies can control S. frugiperda pests to save sustainable maize yields based on the basic principles of sustainable agriculture models. Agroecological steps are taken to reduce the population of S. frugiperda in corn plants by:/ (1) sustainable management of soil fertility, primarily actions that maintain or store soil organic carbon; (2) intercropping with properly selected companion plants; and (3) diversification of the agricultural environment through the management of (semi) natural habitats at various spatial scales.
