The Splicing Technique for Different Sizes

In grafting activities we often face different sizes between the rootstock and the upper stem (entres), of course this requires a separate way to be able to do so that the resulting seed provides a percentage of growth that remains optimal.

The following techniques to connect different sizes between the rootstock and upper stem:

1. The rootstock is bigger than the rootstock

a. The rootstock that has been prepared is cut to the height of the recomencation height of 15-20 cm from the base of the stem
b. Middle part of the rootstock with a depth / length of hemisphere between 1.5 - 2 cm
c. The look on one side of the rootstock that has been divided into the size of the stem
d. Spur-shaped stems with lengths between 1.5 - 2 cm
e. Insert the top stem that has been knotted in the lower half of the stem
f. Make binding on the connection
g. 2 - 3 weeks can see the results of the connection

 

 

2. Rootstock is smaller than the rootstock:

a. The rootstock that has been prepared is cut to the height of the recomencation height of 15-20 cm from the base of the stem
b. Middle part of the rootstock with a depth / length of hemisphere between 1.5 - 2 cm
c. The shape of the stem is spur with a length of between 1.5 - 2 cm and another shape the size of the stem
d. Insert the top stem that has been knotted in the lower half of the stem
e. Make binding on the connection
f. 2 - 3 weeks can see the results of the connection

Land Optimization: Plant Papaya Between Mango Plants

In an effort to efficiency and optimization of land and financing requires the right steps so that land is more productive, but farm financing can be reduced. To implement this technology, Balitbu Tropika tried to optimize the mango crop land by planting the Pomegranate Red papaya plant among the mango plants conducted in September 2015. The method used was to plant Red Pomegranate mango and papaya in almost the same time in the same month. After entering the first year 8 months after planting papaya has been able to produce, this is the beginning of the independence of the land to finance itself both for the pepeya plants themselves and for the maintenance of mango plants as the main crop.
Entering the third year of the mango variety Agri Gardina planted has begun to produce fruit even though it has not been able to provide an economic impact, but this gives hope that land optimization is starting to be felt.
Entering the fourth year, several varieties of Red Garifta mango varieties have raised flowers among the papaya plants that are already in production and the new papaya plant replaces the old plants that have decreased production. With this pattern, it is increasingly giving hope that funding for managing mango crop land can be reduced and even providing optimal benefits for mango crop farmers by planting papaya intercrops.
With optimal maintenance and cultivation of papaya plants will have a production time span of 3-4 years, meaning that the land is able to finance itself with crop yields in this case is Pomegranate Red papaya.

Boosts Quality Production of Quality Banana Seeds, Initiated Tropical Balitbu and Cultivators

Community interest in developing and doing fruit commodity business is increasing. This is indicated by the high demand for seeds. In 2017-2019, the tropical Balitbu produced 625,000 seeds of various tropical fruits. Most of the seeds have been distributed and received with enthusiasm by the community. Until now the production of fruit crop seeds continues to run, both by the Tropics of Balitbu, Seed Centers and by the Department of Agriculture and the private sector.
Bananas are one of the tropical fruit commodities whose demand for seeds is very large, especially the cape varieties. Kepok cape varieties are superior varieties of bananas released by the Tropics of Balitbu in 2009 with SK 379 / Kpts / SR. 120/1/2009. The advantage is high production (20-30 tons / ha), tolerant of fusarium wilt and escape (avoid) from bacterial wilt disease. This variety is a solution and can replace ordinary kepok bananas which are susceptible to bacterial wilt disease.
Provision of high quality banana seeds in good quality is very much needed in the development of banana commodities. BALITBANGTAN as a technology producer must make efforts to accelerate the politicization of technology to the users. Cooperation of various parties is needed in the success of this banana commodity development program. Quality seed breeders / breeders are very important in providing certified superior seeds. The formation and formation of banana seed breeders is a solution in overcoming the scarcity of banana seed availability.
Breeders of the Seven Brothers bananas led by Firdaus tenacious farmers from Jorong Batu Palano Nagari Salayo, Kubung District, Solok Regency, West Sumatra is one of the cultivators of bananas under the guidance of BALITBANGTAN and the Regional Government of Kab. Solok is starting to be known by the public. Starting with the cultivation of superior Tanjung Kepok bananas in his garden since 2013. Firdaus obtained two seedlings from Tanjung Kepit Tanjung Tropical Researchers, now the population of Kepok Tanjung cape in Firdaus has reached 3,000 clumps (3 ha) and is well maintained.
Through technology assistance from BALITBANGTAN Firdaus banana cultivation is growing rapidly and subsequently developed as an official breeder of banana seeds. BALITBANGTAN (Balitbu Tropika) teamed up with West Sumatra BPSB and the Solok District Agriculture Office, to jointly assist in growing and developing the Tanjung Kepok banana seed breeder. BPSB as a government institution authorized to carry out the task of supervision and certification of seeds, has helped accelerate the registration of 200 parent trees and the process of labeling seeds.
When visited by the Balitbu Tropika, BPSB and the Regional Representative Office of Solok Regency recently, the official breeder of the Kepok tanjung banana has produced approximately 14,000 seeds that have been spread to various regions such as Aceh, Riau, Java and West Sumatra itself.
Firdaus hopes his efforts will bear fruit so that he can send his seven children to school and raise the economic level of the family.
Head of Tropical Balitbu Dr. Ellina Mansyah MP stated that seed production is one of the simplest forms of bioindustry that can be applied in the community. Activities can accelerate the downstreaming of BALITBANGTAN technology to the community, through community empowerment. In this case the seed breeder can reap the benefits directly in increasing the level of the economy.

New Superior Varieties of Agrihorti Mango Palace

With the mango collection owned by the Tropical Fruit Crops Research Institute - Agricultural Research and Development Agency, it certainly provides enough opportunities to produce new high yielding varieties, either releasing from existing collections or crossing between existing varieties. To answer the challenge of the availability of mango rootstocks that have good character and are compatible with all varieties of Balitabu Tropical Mango breeder researchers have been testing varieties from the collection in the Palace Experiment Garden, and the result is VUB Kraton Agrihorti with SK Mentan No .: 051 /Kpts/SR.120/D.2.7/3/2019.
