Abstract

Sand mining which continuously done may cause the sand of amount in the bottom of river decreasing and may result, to the destruction of the river if occured for a long period. Revegetation activity must be done on some former sand mining river boundaries. Acacia (Acacia mangium) might be able to grow in low nutrient soil. The purposes of this research is to get information about sub soil and coconut charcoal granting effects towards acacia seedling growth on former sand mining medium.The research showed that the interaction of the added sub soil and coconut shell charcoal is significant to the heightand diameter parameter of acacia seedling while sub soil addition is significant to Dry Weight Total (DWK) parameter. Interaction of 250 g sub soil, 60 g charcoal on 750 g sand is the best treatment to enhance seedling tall growth for about 88.73%. Interaction of 750 g sub soil on 250 g sand is the most significant treatment for diameter parameter for about 71.21% diameter growth. The best treatment for Dry Weight Total (DWK) is shown by interaction of 250 g sub soil and 250 g charcoal on 500 g sand. Charcoal granting independently is not significant to addition acacia seedling growth. The addition of sub soil only showed the best result of 750 g sub soil granting with diameter growth around 71.21%. Key words: Acacia mangium. Willd., charcoal, sand mining, sub soil

Abstract

Mindi is one of commercial tree species for its timber. Sustainable management of mindi community forest can be obtained by inter-planting the trees with agricultural crop such as soybean. This study aimed to analyze physiological respond of mindi and soybean, which were planted in an organic agroforestry system. The research was done in Conservation Unit for Medicinal Plants at Cikabayan, Bogor Agricultural University (IPB). The first study was about the growth of mindi saplings in monoculture and agroforestry systems (with soybean). The experiment used completely randomized design (CRD). The second study was about the growth of soybean in monoculture and agroforestry systems (with mindi), and used split-plot design. The result show that nutrient uptake of N, P, and K in agroforestry system was higher than in monoculture. The increase of nutrient content in agroforestry system led to the higher increase of growth dimensions of mindi tree than the ones in monoculture. The content of soybean chlorophyll planted in agroforestry system was higher than the ones in monoculture. Soybean in agroforestry system had higher nutrient uptake of N, P, and K compared to the ones in monoculture. Soybean productivity in monoculture system showed higher result than the ones in agroforestry. Keywords: chlorophyll, monoculture, root, tree dimension, varieties

Abstract

The environment is a complex system where various factors affect on the plant community in the forest. This theory should be proven by study of the influence of environmental factors to the vegetation of forest stands. This study aimed to analyze the effect of environmental factors, particularly edaphic factors such as soil physical and chemical properties to the vegetation and to examine the effect of edaphic variations to the vegetation variation of Pinus merkusii stands on the plot of 163, Dramaga Forest Research, Bogor. The sample of soil were disturbed sample and undisturbed sample taken by systematic sampling method. There was a tendency that the greater the properties of soil the better the vegetation growth in terms of height and diameter of pine tree. However, that effect was not significant due to the great durability of P. merkusii against marginal soil condition. The soil properties must be supported by other factors such as shading so that the two factors are able to manage the optimal growth of pine trees and maintain the function of forest. Keywords: Pinus merkusii, physical properties, chemical properties, land unit, Dramaga
