Abstract

Nyatoh (Palaquium obtusifolium Burck) is a type of tree that is very much in demand by local and international communities. Nyatoh stands (Palaquium obtusifolium Burck) which is adjacent to the agricultural crops owned by residents in the village, is interesting because it will show that, the level of soil fertility is influenced by vegetation. Not only that, according to local residents, after the land was planted with Nyatoh plants (Palaquium obtusifolium Burck) erosion and landslides had not occurred again.The research was conducted from October to December 2017 located in the village of Sindosa, Sindue Tobata district, Donggala district. This research was started from a field survey, determination of sampling points, soil sampling and analysis of soil samples in the laboratory of the Faculty of Agriculture, University of Tadulako. Soil sampling is done by taking intact soil samples at several predetermined locations namely peaks, backs, and valleys. Each slope is determined by 5 soil sampling points to represent each location with 2 types of depth, namely 0-30 cm and 30-60 cm. Then the samples obtained from these 5 points will be compiled. From the three locations there were 30 soil samples before they were compiled. Overall soil samples after being compiled will get 6 soil samples analyzed at the Soil Science Laboratory of the Faculty of Agriculture to determine the chemical condition of the soil. Data obtained from the laboratory are then analyzed descriptively, namely by describing the chemical properties of the soil, namely pH, CEC, C-Organic and soil organic matter.The results showed an average pH with a depth of 0-30 cm, which is 6.64, while at a depth of 30-60 cm showed a pH with an average of 6.43, Cation Exchange Capacity (CEC) on average below the Nyato stand at Sindosa village Sindue Tobata District Donggala Regency at a depth of 0-30 cm, which is 25.87 (cmol (+) kg ¹) is in the medium category, while at a depth of 30-60 cm is 3.23 (cmol (+) kg kedalaman ¹) belongs to the very low category.

Abstract

Ketapang (Terminalia catappa L.) is one of plant that can grow in critical land like reeds field. Imperata cylindrical (L.) Raeusch is one of plant that can secrete allelopathic substances that is chemicals and it is found on the plants body which is put outside into the environment so it can inhibit or ruin the other plants by using Arbuscular Mycorrhiza Fungi (FMA) as biological fertilizer can increase water absorption and nutrient from the soil. This research used Complete Random Design (CRD) method, and consisted of 4 treatments of arbuscular mycorrhiza fungi that are P0= Without treatment (control), P1= FMA 10g/seedling, P2= FMA 15g/seedling, and P3=FMA 20g/seedling. From the 4 treatment levels, each of them is repeated for ten times, so the total of seedling units that be needed are 4x10=40 (forty) seedling units. The result of this research showed that by giving some dose of arbuscular mycorrhiza fungi type of inoculums consortium by 4 genus (Acaulospora, Gigaspora, Glomus, and Scutellospora), have a real impact toward all the observation parameters that are the high accretion, the diameter accretion, the number of leave accretion, canopy wet weight, root wet weight, crown dry weight, and root dry weight. The treatment dose FMA for 20g (P3) on the polybag gives the mean score of high accretion, diameter, and the biggest number of leave. It show that more and more the high dose of FMA that is applied, than the growth of Ketapang seedling is also getting better because by giving FMA, it can influence the allelophatic substance in the growing media.Keyword: Ketapang, Allelophatic, and Mycorrhiza.

Abstract

Ultisols are mineral soils that develop from old parent materials and have undergone further weathering. Constraints to the utilization of ultisol soils have low organic matter content, acidic soil reactions, low base saturation, high Al content and have a clay to sandy clay texture. Therefore, to reforest it, it is necessary to look for tree legumes that are adapted to grow in these soil conditions. The purpose of this study was to determine the growth of several species of legume seedlings on ultisol soil in polybags. This research was conducted for three months, from November 2020 to January 2021, located in the BPDASHL Permanent Nursery in Palu-Poso, Palu, Central Sulawesi. This study used a completely randomized design (CRD) method with four treatments and ten replications, so that there were 40 experimental units. The treatments were applicated, namely: L1 = Sengon (Paraserianthes falctaria (L.) Nielsen); L2 = Acacia (Acacia mangium Willd); L3 = Johar (Senna siamea Lamk); L4 = Turi (Sesbania grandiflora L). The parameters observed in this study were seedling height, diameter, number of leaves, value of stem stiffness and number of root nodules. The result of study showed that legume seedlings had different growth responses on ultisol soil in polybags. The Sengon (Paraserianthes falctaria (L.) Nielsen) legume species had higher height, diameter, leaf number, seedling firmness and number of noduoles compared to (L4) Turi (Sesbania grandiflora L), (L3) Johar (Senna siamea Lamk), (L2) Acacia (Acacia mangium Willd) legumes.Keywords: Legume tree, ultisol soil

Abstract

Hazelnut (Aleurites mollucana Willd.) is one type of MPTS plant so that hazelnut plants can be used as pioneers in rehabilitation activities. Hazelnuts have a thick seed skin and impermeable or dormant seed properties against water and gas, blocking water imbibisi and oxygen entry into the seeds. Skarification is one of the seed treatment efforts, aimed at breaking dormancy, as well as accelerating the occurrence of uniform seed germination (Sholicha, 2009). There are three types of skarification, namely physical, chemical and mechanical skarification. The treatment of various skarification of hazelnut seeds can increase the germination of hazelnut seeds (Aleurites moluccana Willd.) in real time. This can be seen from the real influence of giving treatment of various skarification to the germination of hazelnut seeds such as the percentage of the number of germinated seeds (G), the average percentage of the number of germinated seeds per day (MDG), the average germination day (GR), and the speed of tumb. Immersion skarification treatment using KNO3 with a consentaration content of 0.2% for 24 hours gives a better influence in the percentage of the number of germinated seeds with an average amount of 44%, the average percentage of germinated seeds per day with an average amount of 0.69%, the average germination day with the number of 42 days, and the speed grows with an average amount of 0.034%/etmal. When compared to other perpetrators.Keywords: Hazelnut, skarification, KNO3, germination
