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

The application of arbuscular mycorrhizal fungi and compost is one of the environmentally friendly technologies to improve the fertility of the planting media so that the results of the seeds are higher of quality. Banana weevil or banana stem is an organic material that has several macro and micro nutrient content, for example N, P and K, and contain chemical compounds in the form of carbohydrates that can stimulate the growth of microorganisms in the soil. Furthermore, arbuscular mycorrhizal fungi (AMF) can increase nutrient uptake from the soil into the roots. The purpose of this research was to determine the effect of the addition of banana weevil compost (Musa balbissiana Colla) and arbuscular mycorrhizal fungi on growing media on the growth of cempaka seedlings (Elmerrillia ovalis (Mig) Dandy). The result of this research showed that the combination of banana weevil compost and arbuscular mycorrhizal fungi on growing media significantly influences the growth of leaf number and dry weight, but no significant effect on growth in height, diameter and wet weight. The combination of banana weevil + soil (P1) compost treatment on growth media gave the growth of cempaka seedlings (Elmerrillia ovalis (Mig) Dandy) better than other treatments. The treatment of banana weevil + soil compost (P1) gives the best effect on all parameters, which is the increase in diameter with an average of 0.70 mm, height increase with an average of 2.70 cm, increase in the number of leaves of 1.70 strands, wet weight with an average of 2.90 g, dry weight with an average of 0.60 g.Keywords: compost,arbuscular mycorrhizal fungi, Elmerrillia ovalis (Mig) Dandy

Abstract

Biomass is the mass of the living vegetation, which also plays an important role in the carbon cycle. Meanwhile, carbon stock is the carbon content stored either on the soil surface as plant biomass, necromass, or in the soil as soil organic matter. Before counting the biomass and carbon stock, we have to count the volume in the tree first. The purpose of this research was to estimate the volume, biomass and aboveground carbon stock stored in the Village Forest area in Lampo Village. This research was conducted for three months, from July 2020 - September 2020 in the Forest Area in Lampo Village, Banawa Tengah District, Donggala Regency. The results of this research showed that the total volume of vegetation in the Lampo Village Forest was 140.17 m³ / ha (trees) and 9.86 m³ / ha (poles); vegetation biomass in Lampo Village Forest is 137.09 tonnes / ha (trees) and 10.00 tonnes / ha (poles); and carbon reserves in Lampo Village Forest are 68.55 tonnes / ha (trees) and 5.00 tonnes / ha (poles). The dominant species group is Bayur (Pterospermum javanicum), of the 8 identified stands.Keywords: Allometrics, Biomass, Carbon Stock
