Abstract

Agroforestry is land used system which combines woody plants (trees, shrubs, rattan) with woody plants or may not with the grass (pasture), sometimes there is a component of the cattle and other animals that formed the ecological interactions between woody plants and other components. The selection of inappropriate agroforestry pattern will affect the growth of staple crops with a high competition to get nutrient elements, air, and light from the sun. This research aims to analyze the influence of agroforestry patterns of gmelina growth and analyze the relationship of land management system on the gmelina growth. This research was done in  Village Sekarwangi, Malangbong, Garut in December 2011 to February 2012. This study used  RAL  analysis with one factorial, agroforestry pattern. There are three patterns of agroforestry  chosen as the treatment. Parameters was observed is  gmelina  dimensions form of  total high, diameter, high free branches, and diameter of  crops. The result showed that agroforestry pattern one exert most good against growth gmelina. It obtained based on the fingerprint variety test and duncan test. Pattern agroforestry one give highest average on each parameter. Besides that, system land management of agroforestry one also exert best to the gmelina growth.

Abstract

Agroforestry was had two main components, those are forestry plant and agricultural plant. Plant species which developed in agroforestry area was been expected to give benefits to communities, those are multifunction characteristic and commercial value. One of potential plant to be developed in agroforestry area was Sentang. The objective of this research was to know the effect of agroforestry to the dimension and rooting system of Sentang. This research used Randomized Complete Block Design (RCBD) two factorials with six treatments; those are sweet sorghum in planting space 2.5 x 25 m, sweet sorghum in planting space 2.5 x 5 m, grain sorghum in planting space 2.5 x 2.5 m, grain sorghum in planting space 2.5 x 5 m, no sorghum in planting space 2.5 x 25 m and no sorghum in planting space 2.5 x 5 m. Those six treatments were located in three blocks; those are block 1, block 2 and block 3.Plant dimension (bottom diameter, diameter on breast height, total height, branch-free height, crown height, crown length, crown width) has an approximately same result for each variable. Research results show that best plant dimension was obtained in treatment of sweet sorghum and grain sorghum in both of planting space.Rooting system was had different result for each variable. The shortest horizontal root length towards planting line was found in treatment of no sorghum in planting space 2.5 x 2.5 m; while the deepest root was found in treatment of sweet sorghum in planting space 2.5 x 2.5 m. The shortest upright root length towards planting line was found in treatment of no sorghum in planting space 2.5 x 5 m; while the deepest root was found in treatment of grain sorghum in planting space 2.5 x 5 m.

Abstract

Jabon (A. cadamba (Roxb.) Miq.) is one of forestry plants that be developed widely nowadays in planted forest or public forest. Jabon included in fast growing species with straight and cilindris stem. It can make Jabon is very intrested for raw material of wood industry. However rapid development of jabon have not been followed with land usage with agroforestry system. Land usage with agroforestry system with appropiate pattern can increase economical revenue and also can realize conservation activity of soil and water below the stand. setting of good planting pattern is affected by root system of plants. It is related with competition of nutrient absorption between main plant and agricultural plant. Beside that, root system also affect crown growth that continually affect on sun light availability, temperature, and humidityfor agricultural plants. This research aims to examine the length and depth of lateral root of jabon on mixture pattern and monocultural pattern. benefit of this research is for giving reference of agricultural species that is appropiate with root condition. The result showed that root system on mixture pattern has longerand deeper root than root on monocultural system. Setting of appropiate planting spaces between main plant with agricultural plant is very needed for avoiding nutrient copetition, water, and light.

Abstract

Soybeans demands in Indonesia is higher than soybeans supply. One of the effort to increase soybeans supply is by agroforestry of soybeans and sengon. The aims of this research were to analyze the physiological response and production of soybeans tolerant shading, as well as the influence of soybeans planting on the growth of sengon. Research was conducted by split plot design with 5 repetitions and 2 factors. The main factor was shading and second factor was varieties of soybeans. The results showed the chlorophyll a, b, carotene and total chlorophyll on N1 (with shading) treatment were higher than soybeans on N0 (without shading). The N, P, and K nutrients absorbtion on N0 treatment were higher than soybeans on N1 treatment. Pangrango variety on N0 treatment was better than the others varieties in both of shading treatment. The production of soybeans tolerant shading in sengon (4 year age) was very low than soybeans without shading. The differences of cropping pattern in sengon did not give significant effect on the growth of sengon diameter. Sengon horizontal roots in agroforestry were more than monoculture. The depth of the roots that <20 cm in agroforestry were more than monoculture. That were might be caused by the differences of nutrients element existence in each area.

Abstract

In Indonesia, natural resources have not been maximally utilized yet, so it brought some problems such as food crisis and restricting the conversion of forest-land into agricultural-land. The presence of agroforestry that developing right now could be one of the solution in order to fix the restricting of forest-land conversion problem. Agroforestry of red canna and sengon could be one of the solution. The aim of this study is to determines the influence of NPK and compost fertilizer dose on the growth of canna under sengon stand. NPK fertilizer dose used in this study are 0 g, 1.5 g, 3 g, and 6 g, while the compost fertilizer dose used are 0 g, 50 g, 100 g, 200 g. Experimental design used in this study are complete random sampling (RAL). The result of this study shows that NPK fertilizer dose affected toward the parameter of height, while the dose of compost did not affected the parameters.

Abstract

Sengon (Falcataria moluccana L.) public forests is still becoming planted by Monoculture system. Alternative solution to optimalize the use of land is agroforestry system. Agroforestry system gives income benefits in non timber product. This research aims to measure shading influence of sengon, kinds of fertilizer, and dosages of organic fertilizer against white ganyong growth. The shading treatments consist of the open area (shade intensity 0%) and sengon shaded area (shade intensity 42%). The fertilizer treatments consist O0 (no fertilizer as control), O1 (POC 350 mL/ha, 450 mL/ha), O2 (POC 700 mL/ha, 900 mL/ha), O3 (POC 1400 mL/ha, 1800 mL/ha) and NPK. The experiment was analyzed by nested design. The results showed that growth of white ganyong on sengon shaded area is higher than open area to parameters hight of plant, length of leaves, width of leaves and plant biomass. Treatments of shading and fertilization did not significantly affect to tuber wights of white ganyong.Key words: agroforestry, Canna edulis, Falcataria moluccana, fertilization, shading

Abstract

A Survey in West Java shows that Mindi (Melia azederach Linn.) is frequently found on the community forest lands as part of a mixed cropping system. These community forest lands have a potential to support food security. Soybean is an important food crop as source of protein in Indonesian. This study aimed to observe the growth of Mindi and soybean in an agroforestry system. This study used a split plot design which consists of two factors. The main factors was Mindi which planted using shade and without shade and the second factors are soybean variety (Argomulyo, Anjasmoro, Grobogan, and Wilis) using four replication. The results showed that differences of Mindi cropping method did not significantly affect the Mindi growth (height and diameter) which has been observed for three months. Wilis had the highest survival rate than others varieties. Both factor shade and varieties giving a very significant effect on the kedelai height at the 3-7 MST age. In addition, it's also very significantly affected the number of leaves trifoleat at the age of 3, 4, and 5 MST. Soybean production in Mindi agroforestry system gaves the higher yield than monoculture system at three months age.Key words: Agroforestry, mindi, soybeans, shade, variety.

Abstract

System which integrating forestry and agriculture is known by agroforestry. Utilizing of unproductive land below the trees will be more optimum. Sentang (Azadirachta excelsa Jack) is one of the plants that can be used in agroforestry system. The aim of this research was to know the effect of agroforestry toward tree dimension and production of some soybean varieties. Research design that was used in this research is split plot design that consisted of 2 factors and three repetitions. Planting pattern as a main plot is a the first factor, consisted of planting pattern of agroforestry (S1) and monoculture (S0). The second factor that was a submain plot is some varieties of soybean which consisted of variety of Grobogan, Anjasmoro, Tanggamus, and Wilis.The results shows that accretion mean of tree height, stem and crown diameter of Sentang in agroforestry plot are bigger than in monocultural plot. Lateral root in monocultural plot is deeper than in agroforestry plot. The difference of plant growth in each planting pattern of agroforestry is affected by interaction among plant component. Utilizing of some soybean varieties in agroforestry of sentang one year old did not result significant production than in monoculture pattern. In this research, variety Tanggamus and Wilis on monoculturural plot has better growth and production than variety of Grobogan and Anjasmoro.Key words: agroforestry, tree dimension, sentang (Azadirachta excelsa Jack), soybean, varieties.

Abstract

One of less known timber species is Azadirachta excelsa (Jack) M. Jacobs known with the trading name as Sentang. Fertilizer as a nutrient supply was given to gain high quality seedlings. One of organic material which can be utilized as organic fertilizer is the waste of soybeans harvesting. Soybeans waste could be used as compost. This research aimed to examine the fertilizing frequency of soybeans compost to the growth of Sentang seedlings and compare them with cow manure fertilizer fertilizer. The frequency of fertilizing used were once a week, once in two weeks, once in three weeks, and once in four weeks during 12 weeks observation. The result shows that fertilizing soybeans compost to the Sentang seedlings once in two weeks give significant impact to the growth of diameter, height, total wet mass, total dry mass, and root-crown ratio of Sentang. Key words: Azadirachta excelsa, frequency fertilizing, soybeans compost
