The development of potato crops in West Nusa Tenggara Province has been carried out in the Sembalun plateau. However, the Sembalun region faces limited infrastructure support capacity, so one of the strategies to increase potato production is to expand potato development to areas outside the Sembalun region, namely to potential medium plain areas.  North Lombok regency has a potential medium plain for the development of potato crops, namely in the santong area of Kayangan subdistrict and Senaru area of Bayan Subdistrict. The National Strategic Excellence Research Team of Mataram University has conducted research for the development of quality potato seeds in the Santong region, followed by the assistance of its development. The results of this sideways show from the aspect of potato cultivation can grow and produce well, but the obstacle faced is the high intensity of attacks of plant destruction organisms. The expansion into this medium plain demands technological innovation of potato production in the medium plain. Therefore, it is considered necessary to conduct sustainable assistance of potato development in North Lombok Regency

Abstract Virus diseases are of key importance in potato production and in particular for the production of disease-free potato seed. However, there is little known about the frequency and distribution of potato virus diseases in Ireland. Despite a large number of samples being tested each year, the data has never been collated either within or across years. Information from all known potato virus testing carried out in the years 2006–2012 by the Department of Agriculture Food and Marine was collated to give an indication of the distribution and incidence of potato virus in Ireland. It was found that there was significant variation between regions, varieties, years and seed classes. A definition of daily weather data suitable for aphid flight was developed, which accounted for a significant proportion of the variation in virus incidence between years. This use of weather data to predict virus risk could be developed to form the basis of an integrated pest management approach for aphid control in Irish potato crops.

Growing potato demands considerable external inputs of pesticides due to its susceptibility to various pests and pathogens. Here we present an attempt to differentiate the Slovak rural landscape with respect to the possibility of effective potato cultivation and to characterise soil parameters of current potato cultivation areas with the aim to increase the sustainability of the potato production. The selection was based on soil climatic, production and economic parameters. By using the GIS tools and existing databases on soil characteristics in Slovakia, maps of soil suitability categories for potato cultivation were generated. In Slovakia, it was found that 12.3% of farmland is very suitable for potato cultivation and that as much as 43.1% is not suitable. Later the specified categories were characterised in detail and specified with respect to geographic, soil, climatic, production and economic parameters. Currently, most potato crops are cultivated on Eutric Cambisols (27%), Chernozems (20%) and Mollic Fluvisols (18%). Loamy soils (65%), soils without gravel (62%), deep soils (74%) and soil situated on plains (55%) are dominant in these regions. We suggest that potato cultivation should be concentrated on the most suitable areas, thereby increasing the economic profitability, improving the ecological stability of the country and supporting the sustainability of the agriculture.

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.

SUMMARYFourteen experiments which studied effects of date of planting in July, date of harvesting and seed rate on seed tuber yields (10–51 mm) of several potato varieties were carried out in four seasons in East Anglia. Seed tuber yields of c. 30 t/ha in Estima, Wilja and Maris Piper and 20 t/ha in Record were produced from the early planting and in all varieties c. 20 t/ha were produced from planting in late July. For maximum seed yield in all varieties, seed rates of 1·5–2 t/ha were sufficient for most harvests from both dates of planting but for the earliest harvest of the late-July planting, seed rates of only 1–1·5 t/ha were required. The value of seed crops was assessed as the number of ware hectares that could be replanted from the seed yield of one hectare graded 10–51 mm. In all varieties, the number of seed-size tubers and replantable hectares increased with increasing seed rate over most of the range, but numbers were close to the maximum at the early harvests. With delay in harvesting, the number of seed tubers and replantable hectares decreased in many experiments, especially from low seed rates, as more tubers exceeded the upper seed size limit. Maximum numbers of replantable hectares of 15, 15, 20 and 25 were found in Record, Estima, Wilja and Maris Piper, respectively.The monetary value of seed crops of Record and Maris Piper was calculated using (i) a fixed price per tonne of seed and (ii) cost of seed per replantable ware hectare. Sale values from the latter were substantially higher than from the former at early harvests in Record and at all harvests in Maris Piper. In Record, differences in sale value between the two pricing methods decreased with delay in harvesting as yields increased while number of replantable hectares varied little. The results showed that high multiplication rates and monetary returns can be obtained from short-season seed potato crops which may follow crops harvested earlier in the same season. The implications for potato production in the UK are discussed.

In the Andean region of Peru, the predominant production system for potatoes is family farming, oriented towards self-consumption, seed provision, and the sale of surplus production. Labor force activities for land preparation, sowing, maintenance, harvest and postharvest are under the responsibility of the family and eventually they hire farm laborers, when parcels are of a considerable size. Approximately 95% of the cultivated surface of potato crops is located in the high Andean zone, from 3000 to 4200 meters above sea level (masl), employing native varieties of tuber seeds and modern seeds introduced to production systems in the past 50 years. Potato systems in Peru, like the majority of underdeveloped countries, are characterized by the co-existence of formal and informal systems. Formal systems prioritize production and commercialization of seeds of just a few varieties positioned in modern markets which are regulated and accredited by a certification body according to the current legislation, while in the informal system the guarantee of seed quality falls under the responsibility of the very producers and users of those seeds.

Conventional farming for potato production in Indonesia has been using NPK fertilizer at high application rates. Any adverse environmental effects that might arise trough this fertilizer use shall be avoided. Application of bioferrtilizer consisted of ArbuscularMycorrhizal Fungi (Glomus sp.) isolated from the potato farming area and Mycorrhizal Helper Bacteria (Pseudomonas diminuta) have been tested to reduce the use of NPK rates in the production of potato crops. The inoculant has been pot-cultured prior to its application on potato crops. The controlled-field site experiment, used the mixtures of spores of Glomus sp. and inoculant of Pseudomonas diminuta, applied at different rates of NPK fertilizer. Results of the experiment showed that the application of Glomus sp. and Pseudomonas diminuta reduced the use of NPK up to 50%, where the growth, nutrients uptake(N,P,K), and tubers of potato had similar effect to the highest recommendation rate of NPK fertilizer (being applied by the farmers). Findings from this experiment confirmed the evidences that application of AM fungi and mycorrhizal helper bacteria could reduce the use of chemical fertilizer which support sustainable farming system. Further step has been done to scale up the production of inoculants for the wider use by local farmers. Keywords:Glomus, Pseudomonas, mycorrhiza, potato, NPK fertilizer.

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.

Maintaining the health, and therefore productivity, of agricultural soils is vital for continued sustainable agricultural production to support the world’s growing population. Potatoes are grown in a variety of agro-ecological systems and are one of the most important food crops worldwide. Potato crops are demanding on the soil with significant heavy machinery traffic, intensive tillage operations and high inputs of fertiliser, pesticides and water. Maintaining or improving soil health can therefore be challenging for growers. This review considers the different aspects of soil health in a potato production context, how to measure them and how they can be influenced by management practices. Soil health is a complex concept encompassing the physical, chemical and biological properties of the soil and their role in ecosystem services and the growth of plants. Although our understanding of soil health and its impact on crop productivity has improved in the last 30 years, many knowledge gaps remain.

Development of black scurf on potato tubers (cv. Nicola) was compared in plants inoculated with isolates of Rhizoctonia solani of three anastomosis groups (AG2-1, AG3 and AG5) which occur in potato crops in Finland. All isolates induced stem canker lesions but only isolates of AG3 formed efficiently black scurf on progeny tubers. Among the AG2-1 and AG5 isolates tested, only one AG2-1 isolate formed a few sclerotia on 13.5 % of the progeny tubers in one experiment. The data indicate that isolates of AG3 differ from those of AG2-1 and AG5 in having a higher ability to form sclerotia on tubers. Therefore, while AG2-1 and AG5 isolates have a broader host range, AG3 is more efficient in producing black scurf, which provides this anastomosis group with more efficient means of dissemination on seed potatoes. These differences probably explain the predominance of AG3 (98.9 % of isolates) in potato crops in Finland and other northern potato production areas.;

Both Globodera rostochiensis (Wollenweber, 1923) Behrens, 1975 and Globodera pallida (Stone, 1973) are considered the most economically important nematode pest. Annual regional survey conduct in Poland have revealed high infestation of pathotype Ro1 to the northwest of the country and presence of new pathotype Ro5 of G. rostochiensis. In 2009-2013 fifty eight soil samples were tested. parasitic root organisms cause significant losses in quantity and quality of potato crops. In many European countries PCN have become a major problem in potato production mainly in starch potato cultivars. The pathotype Ro1 was detected mostly in central and northern Poland and pathotype Ro5 in four separated provinces: malopolskie, lubuskie, lubelskie and pomorskie. The abundance of cysts in location where the new pathotype was detected suggests that is a thread of further spread of pathotype Ro5 of G. rostochiensis in the country. Consequently, producers and farmers need to grow resistant potato cultivars to keep nematode population below damaging level. These results indicate the urgent need to prevent the spread of PCN to non-infested areas. This report focused on identification of nematode pathotypes in soil samples from infested polish fields and presentation of G. rostochiensis distribution on territory of Poland.
