“Keprokisasi”, meaning to plant more mandarin varieties, is one of the programs launched by the government to develop more mandarin varieties due to its high economy value and its potential to compete and substitute the imported citrus fruits. However, there are several obstacles in mandarin development, notably its long juvenile period that is longer than that of tangerines, about 4 year after planting. This is the main reason of farmers favor for tangerines which could bear fruits just after 2,5 year after planting. One of the ways to cut short the juvenile period on mandarin is by using ‘branch bending’. With this method, farmers do not need to worry about the juvenile period since the mandarin varieties could bear fruits at relatively similar age with the tangerines and with high yi
Mandarin cv Terigas has good quality of taste which similar to the taste of honey. This variety is originally adapted in low land as in its center of development, Sambas West Borneo. The taste attracts consumers which in turn opens an opportunity for further development. Though originated from low land area, Terigas could also bear potential to be developed in high land. One of the experiments to investigate this potential development has been done by IAARD in Kliran Experimental Field, Batu East Java. The plants were planted in late 2012. They are now in fruit production phase and will soon followed by harvest time. The plants shows good growth and bears quite heavy fruits which may reflects the application of innovation technology from IAARD. This also means that Terigas could ...
Soil in everyday life means land areas on which variety of works such as agriculture, housing, and so on can be established. While for agriculture, soil has a special meaning, which is a natural medium for plants’ growth. Soil is the result of evolution, has a unique and organized arrangement and consists of layers or horizons that develop genetically. Vertical cross section of the soil shows the structure of the soil horizon called the soil profile. Constituent of the soil profile from top to bottom respectively are O, A, B and C horizons; and so called solum is A and B horizons (Fig beside). O horizon is an organic horizon formed on the top layer of mineral soil, found mainly in forests soil that has not been disturbed. A horizon is the surface soil horizon which consists of a mix
Pacitan sweet orange (Citrus Sinensis) is one of the most popular sweet orange in Indonesia. Within the group, ‘Pacitan’ has the sweetest taste. It has sweet taste even before ripe, so that it often given to a baby and earned the nickname sweet orange "baby" Compared with tangerine, sweet orange has some advantages, which are: it has wider environmental adaptation, grows faster, has higher production, easy to maintain, and suitable for land conservation because of the wider and dense canopy. Farming system of ‘Pacitan’ will achieve maximum profit in the long term if the development and cultivation are done properly starting from the site selection, the provision of quality seeds, crop maintenance and harvesting. Site selection ‘Pacitan’ has a wide environmental adaptability so that i
Currently, Pummelo (Citrus grandis) has been commercially developed in its production center, Magetan Region. In the past, it was planted in the backyard as a minor crop. The growth and yield of the crop could be optimally obtained if planted in appropriate environmental along with good management from land preparation to harvest. Managing pummelo is easier than that of other citrus. It is also rarely attacked by CVPD. Soil Optimal yield of pummelo could be obtained when planted in lowland up to 400 m above sea level. In highland, the growth tends to vegetative phase, fruits need more time to mature, fruit taste gets a little bitter and it prones to fungal disease. It also needs full sunlight and temperature around 22º—33ºC. Rainfall needed is about 1500—2000 mm and 3-4 dry month
