Tsunami-affected rice fields productive again

Lukas Sebayang, BPTP Sumut

Many rice areas in subdistrict Teluk Dalam in

Southern Nias were inundated during the tsunami event two years ago and became saline. This had a damaging effect on plant growth, leading to failed crops. As part of an ACIAR project BPTP Sumut supported the Nias Dinas Pertanian in measuring soil salinity using an EM38 in two tsunami-affected areas: Botohilitano and Nanowa villages, where rice demonstration trials are also located. Results of EM38 surveys in 2006 in both villages indicate that soil salinity levels in these soils were low.

The high rainfall in Southern Nias (>2500 mm/yr), has helped leach salt from the upper layers of the soil profile. Rice yields (tonnes/ha) from the demonstration plots (Ciherang 6.7, Sunggal 6.1, Kapuas 5.9, Cilosari 5.8 and Banyuasin 5.2) demonstrate that salt is no longer limiting rice production on these sites.





Vice Minister of Agriculture to Langkat - North Sumatra: "IP 400 ...?? Well ... it was good"

asfdaf That’s comments submitted by Vice-Minister of Agriculture, Dr. Ir. Krisnamurthi, when listening to the explanation of researcher BPTP North Sumatra, Ir. Akmal, MSi, at the exhibition stand of BPTP North Sumatra at Langkat District on February 9, 2010. Mr. Vice-Minister of Agriculture further said that the ideas for improving rice production must continue to be developed to meet national food needs.

The participation of the BPTP North Sumatra in that exhibition is one method to bring innovative agricultural technologies to stakeholders such as farmers and agricultural extension. In that exhibition, BPTP North Sumatra show some innovation of agricultural technology that has been produced by the Indonesian Agency for Agricultural Research and Development such as new varieties of rice (Inpari, Inpara, Indragiri, and Mekongga), new varieties of soybean (Anjasmoro), new varieties of groundnut (Kelinci and Jerapah), PUTS and PuPS, all of this was introduced to support the program SL-PTT in 2010. BPTP North Sumatra also introduced technology components to support programs IP 400 such as varieties Inpari 1, Silugonggo, Dodokan and the rice harvest equipment type mower.

The farmers' responses to the presence of BPTP North Sumatra stand in that exhibition were positive. It can be seen from the height of the farmers and agricultural extension officers who visit. In stand BPTP North Sumatra, both paddy varieties and harvest equipment type mower is preferred by farmers. Many farmers asked where they can obtain these rice varieties. While the rice harvest equipment type mower very interesting because the farmers using the tool they need not be bent again to harvest rice. Seeing the high interest of farmers, paddy seed producer should be grown in the Langkat district. BPTP North Sumatra are ready to facilitate by providing rice seed source. (esu, ak, rn).


Appreciation and Field Day In Technology Innovation Of Barangan Banana

Banana (Musa paradisiaca) cultivar Barangan is one of local spesific banana in North Sumatera most cultivated as commercial produce. The production of banana in North Sumatera in 2008 was amount of 233,124 ton and approximately 25% as barangan banana production. Barangan banana was used as a fruit table, the flesh of barangan banana has a specific aroma. Barangan banana used as a fresh consumption was fond of by many people and its marketing was to Jakarta, Bekasi, Riau, and Batam. In Jakarta barangan banana was called as Medan banana.

Agribusiness of barangan banana has a potencial to increase farmer’s income, but its availability is not enough due to wilting desease totally can not be controlled. The first effort conducted by Prima Tani Program at Talun Kenas village Deli Serdang district was to produce good quality seeds of barangan banana free from wilting desease. Started from the year of 2008 had been done a pioneering effort to build seed producer of barangan banana by farmer’s group in partisipative way. Had been conducted several meeting with extension workers from Agricultural Services of Deli Serdang district. The first step in 2008 was to introduce to two farmer’s group a complete technology inovation of producing seeds and preparing for seed producer.

Meanwhile, in October 2009 that seed producer owned by one farmer and it is not able to supply barangan banana seeds for the needs of farmers at Talun Kenas village, STM Hilir sub-district, Deli Serdang district. In oder to fresh again the technology of barangan banana started from seeds up to postharvest technology, in December 2009, Manager Prima Tani Deli Serdang district had conducted appreciation and field day activity for innovation technology of barangan banana. This activity was presented by 40 barangan banana farmer from 3 farmer’s groups such as Dalam, Asada Arih and Mandiri farmer’s group and also 2 traders. This event also was presented by extension workers and the Head of Talun Kenas village and the representative Head Agricultural Serices of Deli Serdang district.

To the barangan banana farmers were again introduced the technology for preparation of seeds from bits, seeds from tissues culture technology and technology innovation preparing for plant media in polibag and screen house for the aclimatization process of seeds from tissue culture. All the technology innovation were directly implemented as participative way by farmers at agribusiness clinic of Prima Tani. For the sustainability in good quality seeds was informed with ACTF ( Assessment Center for Tropical Fruits) IPB Bogor in preparation for tissue culture plantlet of barangan banana. Several technology information distributed as a folder were seed technology of barangan banana, treatment and planting system at the field, technology of plastic wrapping, crown banana cutters and delayed ripening in harvested barangan banana. For those farmer’s group were given 150 sheets of blue plastic wrapping and 3 crown banana cutters each.

The representative of the Head of Agricultural Servives Deli Serdang district (Ir. Lomo Hutabalian, MSi) appealed barangan banana farmers in order to make use of technology given by BPTP Sumut, agricultural tools given to Farmers Group during the Prima Tani Program at Talun Kenas village should be taken care and made use of for increasing the production and income.

The leader od Sada Arih Farmer Group and also as a secretary of Gapoktan PUAP Jaya Bersama (Mr. Kumpulen Ginting) asked about the next activity of Prima Tani Program whether is still continued or not in the year of 2010 ? The responses to this question was as followed : the similar activities such as desimination alike in Prima Tani Program will be continued by local government and Assessment Institute for Agricultural Technology (AIAT) North Sumatera would be still active to cooperate with the institutions involved to carry out supervision. The question of participant also asking why the seed from tissue culture are very small compared with the seeds from bits , and how much the price of that seeds if is it ready for planting at the field ? Participant from the member of Dalam Farmer Group (Mrs. Martaulina Kembaren, SP) said : ” Thank you for BPTP Sumut, we have much received technology information of barangan banana started from seeds up to postharvest handling technology, and to the future we still need also guidance from BPTP Sumut”.


North Sumatera AIAT Doing First Harvest of New Improved Variety of Rice in Labuhanbatu District

The harvest of new improved variety of rice was conducted in Selat Besar village, subdistrict of Bilah Hilir on medio January 2010 done together by Head of North Sumatera AIAT (Dr. Didik harnowo), representatives of District Agricultural Office, representatives of District Information and Extention Office, Field Extentionist of Bilah Hilir subdistrict, The manager and the members of Group of Farmers, as well as researchers of North Sumatera AIAT. This was demo plot under the FEATI activity of North Sumatera AIAT. The new improved varieties harvested in this moment were Ciherang, Mekongga, and Inpara 3.

The most popular rice planted by farmers in this region is local varieties called Kuku Balam (KKB) and Tolas. These local varieties have good taste. However, the productivity was low, ranging 2.5 – 3.5 t/ha. Besides, the crop duration was longer (around six months). According to farmers in the area, there was no different in the rice grain price between the local and new improved variety. Since the new improved varieties have shorter in crop duration (around 3.5 months), higher productivity (5.0 – 7.5 t/ha), and no different in the price, it is potential to change the rice varieties with the new improved ones. It is hoped that such changes the income and the welfare of farmers will increase.

Speaking during the ceremony of this activity, the manager of Group of Farmers “Sepakat Tani”, Mr. M. Yakub said that by the demo plot activity guided by North Sumatera AIAT, it would trigger group of farmers to became seed producer of rice in this area. We hoped that in the future this village would become the central of seed multiplication so that we could supply certified seed for other areas, he stressed.

Head of North Sumatera AIAT, Dr. Didik Harnowo during this activity stated that new improved varieties in the form f high quality seeds is one of technology most easiest and most cheapest to be developed by farmers. To implement this, seed producers need to be developed in this area. For this purpose, North Sumatera AIAT ready to help the local government as well as group of farmers, especially in term of expertises and source seed.

FEATI team from North Sumatera AIAT presence in this field day are Jonharnas, Lermansius Haloho, and Cyrus Hutapea. They hoped that the development of seed multiplication in this area was sustainable so that the need of quality seed of new improved variety can be fullfilled.


Gurgur Farmers Interested In Planting New Varieties Of Composites Maize

Up to now, the farmers in Gurgur plants locally maize composite type continously  without any changing of the local varieties. These local varieties have a long crop duration that is about 6 mounths and the results are low at arround 4 tonnes per hectare. Local variety also has a very high plant height (up to 3 m), because it has a high trunk so that in the rainy season and high winds often make this maize plant stem falls and fractures. It also makes farmers to crop fall harvest or the results obtained will be low.
On 19 January 2010, the head of AIAT of North Sumatra Dr.Didik Harnowo to harvested new superior varities of maize under the technology disemmination activity in Gurgur with farmers, field extension officers and local government properly according to the crops need, the yield will be higher. As it proved in Gurgur-Tobasa, Sukmaraga, Srikandi and Anoman could produced 7.7 ton/ha, 7.1 ton/ha, and 7.0 ton/ha of dry grain respectively.
Based in this activity, it could be concluded that farmers in Gurgur interested in using new improved composite maize because it has shorter maize duration and higher yield potential. This implied that the socialization activity for new improved composite maize is needed. The availability of seed for farmers was also important
