Abstract

Tamarind (Tamarindus indica) is a multipurpose tree that can be developed either vegetative or generative propagation. Vegetative propagation of tamarind can produce abundant fruit if the plant organs derived from superior parent trees. However, due to the rare availability of natural tamarind stands now days, then the generative propagation by seed, can be the right choice for its cultivation. Generally, tamarind seeds are dormant, so it requires a pre-treatment to break its dormancy. One way to break it was using potassium nitrate (KNO3). This study aimed to determined the response of soaking treatment to the germination of tamarinds seeds with KNO3 solution at various concentrations and the most effective concentration of KNO3 solution to stimulate tamarind seeds germination. The experiment was conducted at the Greenhouse Seed Control and Certification Institute of Food Crops and Horticulture (BPSBTPH) Lampung Province, from July to August 2013. This research used Completely Randomized Design (CRD), with 5 treatment of KNO3 solution soaking (0.1%, 0.2%, 0.3%, 0.4% and without KNO3) and 3 replications. Every unit of experiments consisted of 100 seeds. Observed parameters included percentage of germination, mean of day germination and percentage of germination seeds per day. Bartlett test was employed to figure out the homogenity of datas. Then, analysis of variance was used to analyse datas. Honestly Significant Difference (HSD) was used to the advanced analysis. The entire data tested on 5% significant level. The result showed that soaking of tamarind seeds in water (without KNO3) during 24 hours gave the best response to break its dormancy, and the most effective concentration to break dormancy of tamarind seeds was 0.4%.

Abstract

Sekampung Hulu watershed that is located in Batutegi Forest Management Unit (KPH) is one of Watershed priority due to the most area has been cultivated by the community. 59% of the community cultivate the forest area have acquired community forest utilization license (IUPHKm). The objective of the license is so that the community could return the forest function at the same time increasing their prosperity. Agroforestry was silviculture system that is believed as the most appropriate mean to realize those objectives. This research was aimed to figure out the silviculture system done by the farmers in KPHL VII Batutegi and its relation with income increasing and soil fertility. Data collection was conducted on August-September 2016 in Batulima Resort KPHL VIII Batutegi, through interview method of 98 respondents of two Gapoktan (farmers group) that have IUPHKm. The research result showed that there is no significantly correlation between IUPHKm appropriations with the change of silviculture system. There was a negative influence of silviculture system to soil fertility and farmer income. Monoculture system on the IUPHKm area provide the highest income. It was influenced by the duration of forest land utilization that has reached 4,2 years in average, therefore harvesting has been done. The other influence factor was fertilization intensity, so that the plantation would be more productive. Keywords: community forest, farmers' income, silviculture, soil fertility

Abstract

Mahagony is one of plants that could fill the needs of wood in Indonesia. The need of wood recently reached 10 million m3 per year. Basically Mahagony plants were very well associated with endomycorrhizal, but there was study that showed the Mahagony plants were able to associated with ectomycorrhizae spore. The aims of this studied were to determine the effected of ectomycorrhizae on Mahagony plant seedlings and the best dose of ectomycorrhyzae inoculation to improved the growth of Mahagony plants. This study was carried out in the greenhouse of the Faculty of Agriculture, University of Lampung on October 2017 - March 2018. The method used is completely randomized design with 4 treatments, 5 replications and 5 units of each experimental unit so that the entire plant amount were 100 experimental units. The dosage applied in this research were 0 ml/polybag, 10 ml / polybag, 20 ml / polybag and 30 ml / polybag. Parameters observed in this study were leaf area, height, diameter, number of leaves, root length, percentage of colonization, and dry weight. The research data obtained then analyzed using a homogenity test, Bartlett test and then proceed with smallest real difference test. The results showed that giving of ectomycorrhizae at a dose of 20 ml/polybag and 30 ml/polybag significantly affected to have higher percentage of colonization than the dose of 10 ml/polybag which is equal 0.67% to 0.84%. In leaf area parameter, the application of ectomycorrhizae with dossages of 30 ml.polybag, significantly showed the lowest leaf area compare to other treatments. It conclude that mahagony plants were not compatible with ectomycorrhizae there for percentage of inoculation in mahagony plants seeds was low and could not help plant grow.
