Basically the rubber plants require the terms of climatic conditions for growth and soil conditions as the growth media.
ClimateAreas suitable for rubber plants is on the zone between 150 and LS 150 LU. Beyond that somewhat hampered the growth of rubber plants that began production too late.RainfallRubber plant requires optimal rainfall between 2,500 mm to 4,000 mm / year, with rainy days ranges from 100 to. 150 HH / year. However, if frequent rain in the morning, the production will be reduced.
High placesBasically the rubber plants grown in optimal lowland with an altitude of 200 m above sea level. Altitude> 600 m from the sea surface is not suitable for growing rubber trees. Optimal temperature range between 250C required to 350C.

WindWind speed is too fast in general is not good for rubber cultivation
GroundDry land for the growth of rubber plants in general require more physical properties of soil as compared with their chemical properties. This is due to the chemical treatment of soil to grow crops in accordance with the terms of rubber can be implemented more easily than with improved physical properties.Different types of soil can grow plants in accordance with the terms of either rubber young and old volcanic soil, even on peat soil <2 m. Volcanic soils have a fairly good physical properties, especially the structure, texture, sulum, depth of soil water, aeration and drainage, but their chemical properties are generally poor due to low haranya content. Usually quite fertile alluvial soil, but the physical properties, especially drainage and poorly aerasenya. Soil reaction ranges from pH 3, 0 - pH 8.0 but did not fit at pH <3.0 and> 8.0 pH. Soil properties are suitable for rubber plants in general are:- Sulum ground to 100 cm, there are no rocks and rock layers- Aerase and adequate drainage- The texture of the soil crusts, and can withstand water poreus- The structure consists of 35% clay and 30% sand- Land bergambut no more than 20 cm- The content of NPK nutrients and not enough of micro nutrient deficiencies- Reaction of the soil with pH 4.5 - pH 6.5- The slope of the land <16% and- Surface soil water <100 cm.
Rubber clones Recommendations
Natural rubber prices improved at this time should be a momentum to boost the acceleration of reform and rejuvenation of the rubber is less productive by using superior clones and cultivation of other technological improvements. The Government has set a target of the development of Indonesia's natural rubber production by 3-4 million tons / year in 2025. Production targets can only be achieved when at least 85% rubber plantation (the people) are currently less productive successfully rejuvenated byusing superior clones.Breeding activities in Indonesia have a lot of rubber produced klonklon excels as a producer of latex rubber and timber. National Workshop on Rubber Plant Breeding, 2005, has recommended a new high yielding clones for the generation-4-year period from 2006 to 2010, the clones: IRR 5, IRR 32, IRR 39, IRR 42, IRR 104, IRR 112 and IRR 118. Clone 112 IRR 42 and IRRstyle = "font-size: medium;"> release will be filed while the other IRR clones have been released officially. Clones showed that both productivity and performance in various locations, but agronomic characters and varied properties of the secondaryother. Therefore, the user must choose carefully the appropriate clones agroecological areas of development and other types of rubber products to be produced.Clones that have removed the old GT 1, AVROS 2037, PR 255, PR 261, PR 300, PR 303, RRIM 600, RRIM 712, BPM 1, BPM 24, 107 BPM, BPM 109, PB 260, RRIC 100 still allow to be developed, but must be done carefully in both the placement and location of its management system. Clones GT 1 and RRIM 600 at various locations reported experiencing problems and Corynespora Colletotrichum leaf disease. Whereas clone 1 BPM, PR 255, PR 261 has a problem with the quality of latex latex so use is limited only suitable for certain types of rubber products. PB 260 clone is very sensitive to drought and the disruption of tapping the flow of wind and drought, therefore its management must be done correctly.
Planting materials
The most important thing in rubber planting the seeds / planting material, in this case a good planting material is derived from rubber trees grafting. Preparation of planting materials dilakuka least 1.5 years prior to planting. In terms of planting material, there are three components that need to be prepared, namely: rootstock (root stoct), entres / upper trunk (budwood), and grafting (grafting) in preparation of planting materials.Rootstocks is a preparatory activity to obtain planting materials that have strong roots and good nutrient absorption. To achieve these conditions, required the development of seedling rootstock that meets the technical requirements which include nursery soil preparation, seed handling, germination, seedling planting, and plant maintenance business at the nursery.
Planting rubber seedlings to be on time to avoid the high mortality rate in the field. Appropriate planting time is during the rainy season. Besides labor need to be prepared for these activities to the manufacture of the planting hole, unloading, transporting, and planting seeds. Seedlings should be planted has been dismantled and are allowed a grace period of at least one night after the demolition. In more detail the preparation of rubber planting material can be seen grafting Books Rubber Farming Sapta Bina (1996, 2nd edition) or the orders of Rubber Materials Management Booklet (in 2005) issued by Sembawa Research Institute, Rubber Research Center.
