a tree for tomorrow

Jabon and sengon were lined up neatly, relatively uniform height, about 15 meters. Among both grow coffee. That's how Agus Sumarno secure income.Agus Sumarno, a grower in the village of Karangwuni, Pringsurat District, County Waterford, Central Java, know exactly rust threatens sengon tumor. Many planters crop failure due to fungal attack Uromycladium tepperianum. If many sengon stricken land, threatened that its supply would also likely increase the selling price. On the other hand, staying jabon-gadangkan can grow fast like sengon. Therefore, it combines three commodities on land 1,000 m2: 200 m2 to jabon, the rest a mix sengon and coffee.
Agus obtain seeds from a researcher in Yogyakarta. At first he thought jabon are fruit trees. However, after receiving an explanation that jabon hardwood plants like sengon, he enthusiastically cultivated. 'I am sure that whatever kind of woody plants must be sold. Moreover, if rapid growth, the velocity of money too fast, 'said sengon planters since 2004. Therefore, at the end of 2005, he planted 30 seeds jabon.
Spacing
According to Dr Supriyanto, silviculture specialist of the Southeast Asian Regional Centre for Tropical Biology (SEAMEO BIOTROP), a fusion sengon, jabon, and coffee in one area is possible. Sengon Fabaceae plant family members famous as the 'producer' of being able to bind nitrogen nutrients from the air. While jabon rapid growth upward and branching are not widened. 'Secondly it gives room for plants growing coffee, "said Supriyanto. Sengon and jabon fitting used as a shade that Coffea sp.
According to Dr Eko Bhakti Hardiyanto, lecturer at the Faculty of Forestry Gadjah Mada University (UGM), jabon spacing minimum of 4 mx 4 m. 'If the spacing is wider better growth, "said Eko. When planting mixed with sengon jabon, adjust the spacing for jabon not overshadow sengon. According Supriyanto, if jabon used as shade coffee, spacing needs to be widened, for example 5 mx 5 m.
Every 6 months when jabon ages 1-3 years, Agus routinely fertilize with manure and NPK. After a 3-year-old plants, fertilization is stopped. However, he still cultivate coffee with NPK. When dry Agus do not flush, but still a good crop growth. Now jabon plants that were 4 years old that have reached a diameter of 18 cm.
A year later sengon Agus attacked caterpillars in the garden bags - caterpillar married sengon skin color cones, but the pest was not transmitted to the jabon. According to Dr Ir Sri Rahayu MP, forest pathologist from FKT UGM, the disease is unlikely to attack plants sengon jabon. Family both crops was different. Sengon: Fabaceae, jabon: Rubiaceae.
According to Sri Rahayu and Eko, jabon more risky than the disease infestations. Pests jabon known at this time of leaf-eating caterpillars and stem borer. 'To date I have not received reports of cases of disease in jabon,' said Sri Rahayu. The other pests that are known to attack plants and need to be aware planters jabon among others uret leaves and caterpillars.
Teak
Options other crops can be grown together jabon still a lot. 'One of my clients have tried to plant teak and sengon jabon together,' said Santi Mia Sipan, marketing director of PT Jaty Arthamas. Still the largest proportion of teak because they're expensive. Unfortunately, all three plant growth has not been determined because the activity has only run a year. According to Eko, if jabon would be planted with slow-growing plants, the plants should be planted before planting planters jabon. If no headers jabon blocking sunlight dibutiuhkan companion plants to grow. Sri Rahayu never find planting sengon and jabon in polyculture. Sengon growth slow due to be planted later so that the closed canopy jabon. Though sengon need sunlight to photosynthesize.
In addition to perennials, jabon can also be intercropped with crops such as maize, cassava, and peanuts. It's as did Muhammad Insyaf in Cirebon, West Java. Alternate crops planted in beds 1 m-wide beds Yields could support its own garden ready for cutting waiting jabon 7 years later.
