IndonesiaFinished Planting 1,000 Tejakula Tangerine Seeds, Unud Commitment to Accompany the Society
Udayana University Research and Community Service Institute (LPPM) once again planted 400 Tejakula tangerines and 40 turi plants in 3 villages in Tejakula District of Buleleng, Sunday (02/07/2020). 200 Tejakula tangerines and 20 turi plants were planted in Tejakula Village, while 100 Tejakula tangerines and 10 turi plants were each planted in Les Village and Bondalem Village.
"With this activity today we planted 1,000 Tejakula tangerines and 200 turi plants in 4 villages in the Tejakula region," said Prof. Dewa Ngurah Suprapta was accompanied by the research team Prof. I Gede Rai Maya Temaja, Dr. Khamdan Khalima, and local village farmers. Previously, LPPM Unud had planted the same tree seedlings in Sembiran Village, which is also the target of Buleleng's superior citrus cultivation.
He believes Tejakula tangerines which are planted using an intercropping planting system with the turi plant are able to develop properly. At least in a period of at least 2 years, Tejakula tangerines are able to show the ability to bear fruit. "We can evaluate it in about 2 years, this plant learns to bear fruit. Optimally 3 to 4 years, plants will show optimum fruiting ability, "he added.
Prof. I Gede Rai Maya Temaja, a researcher who is also the Chairperson of the LPPM of Udayana University, admitted that he was committed to conducting assistance and monitoring the field. Assistance is carried out since the research, planting to the village, to the evaluation by involving students and related agencies. "We are committed to monitor what we submit to the community to be well maintained, whether to grow well, if there are disturbances, also involve KKN students, student scientific activities, and monitoring from the local government," he said.
LPPM Udayana University also submitted biostimulants or plant stimulants developed by the Faculty of Agriculture Biopesticide Laboratory to local village farmers. According to Prof. Dewa Ngurah Suprapta, this biostimulant is useful to spur growth and plant resistance to pathogens such as the attack of CVPD (citrus vein phloem degeneration) engender the death of Tejakula tangerines. With this biostimulant, plants can increase the amount of root hairs, so they can better absorb water and nutrients. Biostimulants are given to citrus seedlings before planting and again given to the soil planted with seeds. "At the time of nursery we have given (biostimulant), then when planting we also add more so that in the land where we plant the seedlings can develop," added Prof. Dewa Ngurah Suprapta.
The turi plant which is planted next to Tejakula tangerine seed serves to maintain the humidity of the garden and reduce stress levels in the plant due to drought. In addition, flowers, fruit and leaves can be consumed as vegetables. Turi plants can also increase the biodiversity of insects that are beneficial to plants.
Tejakula tangerines flourished in the 1980s. However, due to CVPD disease, the population has declined and has become extinct since 1983. LPPM Udayana University is also trying to re-breed this Tejakula Teangerine with the innovation developed by the research team. The intercropping system between Tejakula tangerines and turi plants is the first innovation to be studied and developed. (Udayana Media)
