Abstract The high-quality potato seed availability in Indonesia always to be attempted continuously by Indonesian governments to encourage national potato production optimization. One of the efforts is through aeroponic potato seed production. The G0 (zero generation seed) aeroponic potato produces a better yield and healthier tuber compare to G0 conventional potato production. IVegRI has undertaken studies related to G0 potato aeroponic. The results have been disseminated and some of them have been adopted by the potato producers in various regions in Indonesia. The study aimed to investigate the potato aeroponic seed production in Indonesia based on the producers’ perception of the benefits and challenges. The study was conducted from April to December 2017, in 8 districts from 6 provinces, engaging 18 G0 aeroponic potato producers. Data were analyzed descriptively. The resulting study showed that G0 aeroponic producers perceived the production of G0 aeroponic potato as more profitable compared to G0 conventional. The advantages covered: the production was higher, the yield tuber was healthier and sterile, and also it could be produced anytime. Meanwhile, challenges faced were: initially investment cost was quite expensive, electricity installation frequently was unstable and, the challenge concocted a suitable potato aeroponic nutrition.

<p>Kentang merupakan sayuran yang memiliki prospek untuk mendukung program diversifikasi pangan. Akan tetapi saat ini produksi di dalam negeri masih rendah akibat penggunaan benih yang kurang bermutu. Sistem irigasi tetes berpeluang untuk diterapkan pada produksi benih kentang G0. Penelitian  bertujuan untuk mengetahui pengaruh frekuensi dan volume fertigasi terhadap produksi benih G0 kentang pada sistem irigasi tetes. Penelitian  dilaksanakan sejak bulan Mei sampai dengan September 2016 di Rumah Kassa Desa Cikahuripan, Lembang, Bandung Barat, Jawa Barat dengan ketinggian 1.200 m dpl. Percobaan menggunakan rancangan petak terpisah (split plot design) dengan rancangan acak kelompok lengkap dan tiga ulangan. Sebagai petak utama adalah frekuensi fertigasi sebanyak 3, 5, dan 7 kali. Sebagai anak petak adalah volume fertigasi (ml) setiap aplikasi, yaitu 100, 200, 300, dan 400. Hasil penelitian menunjukkan tidak terjadi interaksi antara perlakuan frekuensi dan volume fertigasi terhadap semua peubah pengamatan. Frekuensi fertigasi terbaik terhadap bobot ubi per tanaman umur 100 HST adalah lima kali, yaitu jam 7, 10, 12, 14, dan 16. Volume fertigasi terbaik terhadap jumlah ubi ukuran besar umur 100 HST adalah 300 ml per aplikasi per polibag. Volume dan frekuensi fertigasi terbaik ini diharapkan tidak saja meningkatkan produksi benih, tetapi juga keuntungan usahatani yang diperoleh. Perlu dilakukan penelitian lebih lanjut untuk menginduksi pengumbian dengan mengalihkan ukuran ubi menjadi peningkatan jumlah ubi sebagai tujuan produksi benih G0.</p><p><strong>Keywords</strong></p><p><em>Solanum</em> tuberosum L.; Irigasi tetes; Fertigasi; Frekuensi; Volume</p><p><strong>Abstract</strong></p><p>Potato is one of vegetables that can be used as an alternative to support food diversification programs. But the potato production domestically is still low because of low quality seed. One of the potato seed technologies that can be developed is arragement of fertigation volumes and frequencies on drip fertigation. The objective of this research was to determine the best fertigation volume and frequency in G0 potato seed production in drip irrigation. This research was conducted from May to September 2016 at Screen House Cikahuripan Village, Lembang, Bandung on 1,200 m asl. The treatments were arranged in split plot design with randomized complete block design and three replications. The main plot was fertigation frequency which was consisted of three levels; 3, 5, and 7 times per day. The subplot was fertigation volume which was consisted of four levels; 100, 200, 300, and 400 ml per aplication. The result showed there was no interaction between fertigation frequency and volume on all observation. The best fertigation frequency on tuber weight per plant at 100 day after planting was five  times, i.e. 7, 10, 12, 14, and 16 o’clock. The best fertigation volume on number of big tuber at 100 day after planting was 300 ml per application. The best fertigation volume and frequency will increase not only seed production, but also profit of bussiness. Next research will be done to induction tuberization by transfering measurement of tuber to increase the amount of tuber as goal of production of G0 potato seed.</p><p> </p>

This experiment was carried out in the greenhouse of the sub-region agrarian direction at Kishuara district in the province of Andahuaylas of the Apurimac region of Peru under the aeroponic production system. Growth-associated factors and pre-basic seed production were evaluated in ten varieties of native potatoes using aeroponic conditions in Kishuara - Peru. A complete randomized blocks design was used, and the experimental unit consisted of 12 plants spaced at 20 cm x 18 cm. The variables under study were: height of the plant (average of 12 sampling plants), days to the tuber formation, survival rate (%), days to senescence of the plant, diameter of the stem at senescence, days to the first harvest, yield, number of tubers per plant, and the average weight of tubers. Huayro variety reached the highest growth in plant height (133 cm), the highest yield (981 g / plant), and the highest average weight of mini tubers/plant (12.5 g / plant). The Q'ompis variety was the most precocious (39 days to tuber formation). The days to the first harvest were 96 days for the varieties: Duraznillo, Yana Suytu, Q'ompis and Camotillo, and 125 in Q’eq’orani. Huayro seems to be the best variety to be used for generation of new cultivars and exploitation as native variety for potato seed tuber under aeroponic production system. Our study open the possibility for production of best quality pre-basic seed for native potato production in Peru.

Utilization of healthy planting material is a key factor to improve potato yields to reduce the dissemination of diseases and pests. Quality seed is one of the major bottlenecks hindering the production and productivity of potato in major potato growing regions of the country. Therefore, participatory on-farm seed production and improved potato technologies promotion have been carried out during the year 2014-2016 at five districts, Jeldu, Dendi, Wolmera Degem and Kersana Malima of central Ethiopia. To produce quality potato seed various rapid multiplication techniques were used. Thus, improved potato technologies were demonstrated using different methodologies such as the farmers’ field schools, the farmers' research group and field days. To supply clean tubers about 138,886 high-quality mini-tubers of improved varieties of Belete, Gudanie, Jalenie and Awash were produced. Moreover, a total of 257.08 tons of seed tubers of 15 released potato varieties were produced and disseminated in different parts of the country for research and developments. The participant farmers produce 442.9 tons of relatively clean seed tubers and sold to different parts of the country. During, this activity positive selection technique was demonstrated and participant farmers applied the techniques that helped them to improve the yield and quality of seed potato. Farmers obtained a 40% yield increase and a 33% vigour improvement when positive selection techniques were applied. Training on improved potato production and postharvest handling technologies have also been given for farmers, development agents, agricultural experts and home agents. Therefore, decentralized quality seed production reduces the movement of dangerous diseases like bacterial wilt and viruses from invading areas with high potential for seed production due to purchase of seed only from within one’s same region.

The main objective of this study was to determine the extent of adoption of improved potato production technologies by the potato growers. Data were collected from 231 potato growers of three highly concentrated potato growing Upazilas, namely Pirgachha (Rangpur), Munshiganj Sadar (Munshiganj), and Shibganj (Bogra) during October 2010 to February 2011. The potato growers showed marked individual differences in their socio-economic characteristics and majority of them belonged to middle age category having small family size, primary level of education, small farm size, medium innovativeness, and medium contact with extension personnel. The study revealed that highest proportion of the respondents in Munshiganj Sadar belonged to high adoption category in case of BARI recommended potato variety (72.6%), optimum planting time (87.7%), use of balanced fertilizers (45.2%), whereas medium adoption categories were found in quality potato seed (52.1%), proper seed size (47.9%), fertilizer application methods (71.2%), optimum irrigation (89%), earthing up (84.9%), plant protection (74%), and low adoption categories were found in maintaining proper spacing (42.5%). In Pirganj of Rangpur, highest proportion of the respondents belonged to high adoption category in case of BARI recommended potato variety (77%), optimum planting time (83.8%), whereas medium adoption categories were found in the use of quality potato seed (64.9%), balanced fertilizer (43.2%), proper seed size (52.7%), fertilizer application methods (87.8%), optimum irrigation (97.3%), earthing up (86.5%), plant protection (93.2%), and low adoption categories were found in maintaining proper spacing (64.9%). In Shibganj of Bogra, highest proportion of the respondents were found in high adoption category in case of BARI recommended potato variety (75%), optimum planting time (86.9%), whereas medium adoption categories were found in use of quality potato seed (52.4%), balanced fertilizers (47.6%), fertilizer application methods (78.6%), optimum irrigation (95.2%), earthing up (88.1%), plant protection (76.2%), and low adoption categories were found in maintaining proper spacing (59.5%) and proper seed size (57.1%). The study also revealed that highest (53.4%) proportion of the respondents in Munshiganj Sadar belonged to high potato yield (above 29 ton/ha) farmer category while medium potato yield (between 19 to 29 t/ha) category were found in other two areas i.e., Shibganj (58.80%) and Pirgachha (79.50%). Education, farm size, subsistence pressure, annual income, contact with the sources of information, farming experience, attitude, and knowledge on potato production showed significant positive relationship with adoption of improved potato production technologies.

The availability of Indonesian potato seed and production of potato for consumption depends on the availability and quality of Generation 0 (G0) potato seed. This study aims to observe G0 potato seed production management in Indonesia. Data were collected through Focus Group Discussion (FGD) and survey. Thirty-seven G0 potato seed producers participated in the survey. Data were analyzed descriptively, while the feasibility of the farm budget of G0 potato production was calculated using the enterprise budget method. The results showed that the producers had challenges on capital to broaden the screen house to extend the production scale and limited plantlet availability. Meanwhile, they did not have any problems with other production aspects, such as controlling pests and diseases and the marketing of the G0 seed. Government supports to provide screen houses to fulfil producers' necessity and delegate the legality of potato plantlets are needed to create a better Indonesia's potato seed system.

The yield of seed size tubers was assessed in five standard potato cultivars (Cardinal, Multa, Ailsa, Heera, and Dheera) in relation to dates of dehaulming (65, 70, and 80 days after planting) in a Seed Potato Production Farm, Debijong, Panchagarh during 1996-97 and 1997-98. Dehaulming at 70 days gave maximum seed size tubers (19.75 t/ha ≈ 76%) but significantly identical to 75 days (19.56 t/ha ≈70%) and 80 days (18.69 t/ha ≈ 63%). Considering all the parameters studied, the performance of Heera proved to be best among the cultivars grown. Among the cultivars, the maximum seed tuber yield was recorded from Cardinal at 80 DAP followed by Heera and Cardinal at 70 DAP, Dheera and Ailsa at 75 DAP. In general, most of the cultivars gave the maximum seed tuber yield when the crop was dehaulmed at 70 and 80 DAP and the lowest from 65 DAP. Key Words: Dehaulming, potato, seed production.

Potato (Solanum tuberosum L.) is one of the sought-after horticultural commodities and has a high economic value. Potato production in Indonesia is still relatively low compared to potato production in other countries. One obstacle in producing potato is the use of sufficiently high capital in potato seed production activities. Kertasari Subdistrict is one of the areas of potato seed production in West Java, especially in Bandung District. Capital constraints have caused farmers have to look for sources of financing that can meet their needs in order to continuously produce potato seeds. Some farmers rely on formal and non-formal financing sources while some others are able to meet capital needs with personal costs. The purpose of this research is to identify funding sources and potato seeds produced by farmers in Kertasari Subdistrict, Bandung District. This research uses a quantitative research design using a descriptive approach. Data analysis tools used are descriptive analysis using cross tabulation analysis. The results showed that farmers who produced potato seeds in Kertasari Subdistrict, Bandung District with funding sources from commercial banks, relatives or neighbors, and private funds had higher production yields compared to farmers without funding from these sources. Whereas farmers without funding from farmer groups, buyers, and agricultural kiosks, had higher production yields compared to farmers who had funding from these sources.
