Abstract:
The quality of potato seeds is important to support increased production. The majority of farmers do not certify potato seeds, which can result in various risks for potato seed production activities. This research aims to identify the risks of potato seed production and formulate risk control strategies for potato seeds production. The research uses house of risk method. The results of this study show thirty-nine identified risk events. The most impactful risk event was rotten potato. Thirty-two identified risk agents with two priorities must be handled first. The most effective ways in handling strategy are training, the certification of potato seed breeder farmers, potato seed certification, as well as purchasing breeder seeds from vegetable crop research center and from other seed breeders. This research suggests the needs to produce quality potato seeds by certifying potato seed and to update the competency certification of potato seed breeders.

Abstract:
Potato is an important food and cash crop globally and faces many challenges in Pakistan. These challenges include issues with soil fertility, pest and disease pressure and shortages of high-quality seed potatoes. The scarcity of high-quality seeds is a massive hassle in Pakistan. Farmers in Pakistan, often reuse their seeds or obtain them from informal sources. This practice leads to increased seed quality deterioration and tuber-borne diseases, resulting in decreased yields. To address this situation, aeroponic techniques can effectively meet this challenge. Aeroponics is a novel technique for producing high-quality seed potato, aiming to address the challenge of seed production. Aeroponic techniques are commercially practised in many countries. Thus, in this review, we have highlighted the importance of aeroponic technology and how this technique can help uplift/boost up the seed potato production system in Pakistan. The overview concludes that aeroponic seed production offers numerous benefits, including improved yields, and resistance, even as keeping natural resources. Despite the challenges, the evaluation indicates that the implementation of aeroponic seed production technology in Pakistan may offers a promising and sustainable technique for seed potato production in Pakistan.

Abstract:
High yielding varieties and sound planting materials are prerequisites for sound seed potato production. Low multiplication rate, high seed (tuber) rate, dynamic amassing of degenerative infections, perishability and massiveness are the inherent issues in seed potato production. This may result in non-accessibility/non-availability of sufficient amounts of value seeds at reasonable cost and seed cost alone reflects 40% which is half of the aggregate expenses of development in potato. To go around a portion of these issues, a few alterations, for example, tuber ordering for infection opportunity, seed increase stages and seed accreditation guidelines have been created and incorporated with regular potato seed generation programs. The advent of tissue culture, in which virus-free plants can be produced through meristem culture, maintained indefinitely under controlled conditions and multiplied in artificial media under sterile conditions in the laboratory throughout the year irrespective of growing season, has revolutionized seed production in potato world over. Recent developments in automation of minitubers production have further enhanced adaptability of these techniques in potato seed production. In addition to quality assurance through meristem culture, aeroponic technique of minitubers production ensures high multiplication rate at initial stages of quality seed potato production.

Abstract:
The average food consumption for potato commodities in Indonesia is 2.20 kg/capita/year, an increase of 9% from 2013. The need for potato consumption will increase as Indonesia's population increases. The growth rate of potato production is lower than that of potato consumption; therefore, it is necessary to increase potato productivity. The productivity level of potatoes in Indonesia is still low and fluctuates, with an average potato productivity of 18.23 tons/hectare. Increasing potato productivity can be done by increasing technical production efficiency or using certified seeds. The purpose of this study is to analyze the effect of using certified seed on the production and technical efficiency of potato farming in the Pangalengan district as one of the potato production centers in Bandung Regency. The technical efficiency analysis of the potato crop was performed using the Cobb-Douglas Stochastic Frontier Analysis production function with a total of 70 potato farmers as respondents, with details that 30 persons are using certified potato seed and 40 persons are using not certified potato seed. The results indicate that using certified potato seed has increased potato production. Overall, the average technical efficiency of potato production in the Pangalengan district is 70.10%, which means efforts to improve efficiency are still required. There is no significant difference in technical efficiency between potato farms using certified seed and not certified seed which means using certified potato seed has yet to be able to increase the technical efficiency of potato farms. One of the factors that significantly affect technical efficiency is land ownership status.

Abstract:
Potato (<i>Solanum tuberosum</i> L.) is an important vegetable that plays a vital role in global food and nutritional security and alleviation of poverty, especially in Bangladesh. Although, the soil and climatic conditions of Bangladesh are favourable for potato cultivation, every year production is hampered due to use of low quality seeds. Seed potato industry is developing in Bangladesh. However, only 5-10% quality seeds are being produced and used by the potato farmers. Quality seeds alone can contribute to increased yield by 15-20%. Both public and private sectors together supply only 5% quality seed potato and the rest 95% is almost of low quality produced by the farmers themselves. In prioritizing different issues of agriculture, challenges of production and supply of quality seed to the farmers should be considered as a top priority issue. For increasing quality seeds, the whole seed system needs to be reviewed. The present work was an attempt to review the seed potato production systems, supply system and also to identify the possible challenges and policy implications in regards of the problems on seed potato in Bangladesh.The Agriculturists 2015; 13(1) 173-188

Abstract:
The present study analyses the gaps and issues in the production and distribution system of potato seeds in Nepal. Households’ survey combined with focus group discussions (FGDs) and key informant interviews (KII) were carried out to collect the information. Gross benefit and descriptive statistics were employed for the analysis of the data. Results revealed that National Potato Research Program (NPRP) and some private companies were responsible for the zero generation Pre-Basic Seeds (PBS) production. National Centre for Potato, Vegetables and Spice Crops Development Program (NCPVSCDP) collects the seed demand and helps in potato seed certification at the farmers’ level. The current production is inadequate to meet the demand. As the present potato productivity is 16.72 mt ha-1 which is less than projected by National Seed Vision (NSV), reducing the yield gap is one of the important ways to meet the demand. The Gross benefit per hectare of first-generation basic potato seed (BS1) was NRs 14, 66,667 ($ 12,759) and second-generation basic potato seed (BS2) was NRs 9, 20, 667 ($ 8,009). However, the potato seed system is not working effectively in Nepal. Therefore, the adoption of improved potato varieties should be extensive through a strong mechanism for maintaining the full seed cycle and its proper distribution. Further, it is equally important to change the perception of farmers by showing the comparative benefit of growing ware potato and seed potato.

Abstract:
Pre-basic seed potatoes are disease free potato minitubers produced by transplanting pathogen free in vitro potato plantlets under protected condition in aphid-proof glasshouse and/or screen house. Double antibody sand witched - enzyme linked immuno-sorbant assay is used to test six major potato viruses, namely PLRV, PVS, PVX, PVY, PVA and PVM. Thermotherapy cum meristem tip excision techniques are used to eliminate these viruses. Virus free in vitro potato plantlets are rapidly propagated by single nodal cuttings on modified MS media. For pre-basic seed production disease free in vitro potato plantlets are transplanted in the sterile sand soil substrate under glasshouse and screen house, once in autumn season and next in spring season. Since 1990, National Potato Research Program has been producing about 200,000 pre-basic seeds annually. So far, PBS of 19 different recommended and released potato cultivars has been produced. Till date 3,465,799 PBS had been produced and 3,217,666 pre-basic seeds distributed to the different seed potato growers groups, District Agriculture Development Offices, government farms/research stations, and NGOs/INGOs for subsequent basic seed potato production. After establishment of tissue culture facilities in National Potato Research Program, the productivity of potato has been increased by 71% due to utilization of pre-basic seed potatoes.Nepal Agric.

Abstract:
Rapid multiplication of potato seed using cuttings is a pivotal strategy for ensuring seed availability. This study aimed to elucidate the interactive effects of node number, paclobutrazol concentration, and planting density on seed potato and cutting productions. The study consisted of two experiments. The first experiment evaluated two genotypes (Granola and PKHT-6) with one or two nodes per cutting. The second experiment investigated planting density (one, three, or five plants per polybag) and paclobutrazol concentration (0, 15, 30, and 45 mg L-1). Notably, node number did not significantly influence cutting success, despite genotype-specific and interactive effects on vegetative parameters like plant height, stem diameter, leaf number, and root length. Planting density had no statistically significant impact on all vegetative parameters but demonstrably affected all production parameters. Conversely, paclobutrazol concentration significantly affected all vegetative parameters and influenced all production parameters except tuber weight per plant. From the results of this research, the use of single cutting is more recommended because it will obtain more plant material compared to two-node cuttings. Thus, in a more global context of potato development, this has the potential to increase the production of potato seeds from cuttings twice as much as the current seed production. The use of three plants/polybags is more recommended since it will produce more tuber but not different with five plants, and the use of paclobutrazol 15 mg L-1 is also recommended to increase the number of tubers. In this way, the production costs of G0 potato seeds can be reduced so that the availability of G0 potato seeds will be more guaranteed and affordable.

Abstract:
The technological process of growing potato seed material begins with the acquisition of the source material and its accelerated reproduction to the required volumes. To include new perspective varieties and hybrids in seed programs, they must be released from a viral infection. Exemption from viruses is a responsible, time-consuming and costly process that requires professionalism, but in the absence of this stage, promising varieties cannot participate in the implementation of seed programs. Only in vitro, a material thoroughly assessed with regard to the presence of pathogens, the varietal typicality and severity of the main variety distinctive features can ensure the high quality of seed potatoes in basic seed production.

Abstract:
Potato (Solanum tuberosum L.) varieties Atlantic and Granola are widely grown in Indonesia. The optimal method of cultivation in the tropics, due to the susceptibility of cut seed for disease, is by small (20 to 55 g) whole seed potatoes. However, the variety Atlantic produces mostly large tubers, which are not suitable for planting as whole seeds. Although Granola produces a reasonable proportion of small tubers it still produces a few in the larger size grades and there is no fresh market in Western Australia for the larger tubers for this variety. The aim of this study was to develop methods to be used in Western Australia that improve the yield of small seed potatoes for export to Indonesia. The influence of seed-potato storage duration (at 4°C) on subsequent stem growth was assessed after 30 days growth in a glasshouse (22°C/18°C, day⁄night). Seed potato storage for 22-28 (Atlantic) and 24-30 (Granola) weeks resulted in development of higher numbers of stems. A series of field experiment were designed to increase yield of small tubers. Apical sprout removal in Granola, but not Atlantic, increased the number of stems (by 27%), yield of 20-55 g potato (by 32%) and total yield (by 17%). Application of herbicide (paraquat + diquat) at low concentration during early tuber initiation decreased total yield in Atlantic (by 14%) and Granola (by 16%). Treating whole seed potatoes with carvone vapor two weeks before planting had no influence on stem or tuber number in both Atlantic and Granola but in Atlantic only, the total yield was reduced by 12%. Spraying plants with paclobutrazol during early tuber initiation inconsistently influenced tuber number and yield between the two varieties and two experiments. The influence of gibberellic acid (GA3) on stem number, total tuber number, yield of 20-55 g tubers and total yield was investigated by dipping seed pieces in a GA3 solution (20 mg⁄L) two days prior to planting. In Atlantic, GA3 treatment increased stem number (by 147%), total tuber number (by 75%) and yield of 20-55 g tubers (by 330%) without influencing total yield. In Granola, GA3 treatment increased stem number (by 50%), total tuber number (by 15%), yield of 20-55 g tubers (by 21%) and total yield (by 10%) The influence of gibberellic acid application (20 mg⁄L) to seed pieces before planting increased the number of small tubers through increased stem number. The shift toward a greater proportion of small tubers, without reducing total yield, had a greater influence in Atlantic than that in Granola. Treatment of GA3 and paclobutrazol together decreased total yield compared to that of GA3 alone

Abstract:
A protocol is presented for the rapid (28 days) induction of microtubers on micropropagated layered potato plantlets of 'Kennebec', 'Russet Burbank' and 'Superior' in medium devoid of growth regulators. With this method the addition of coumarin, 6-(2-chloroethyl)-trimethylammonium chloride and 6-benzylamino-purine to the microtuberization medium either had no effect or significantly reduced microtuber weight per plantlet. Increasing the incubation period from 28 to 56 days significantly increased the weight of microtubers per plantlet and the proportion of microtubers heavier than 1 gram. Increasing the volume of microtuberization medium from 50 to 100 ml significantly increased the number of microtubers per plantlet. Microtuber dormancy periods were cultivar-specific and microtubers $ le$250 mg had longer dormancy periods as compared to microtubers $>$250 mg. A positive correlation was established between endogenous abscisic acid levels and microtuber dormancy periods. Microtubers $ le$250 mg had lower specific gravity, fewer eyes and produce fewer sprouts than microtubers $>$250 mg. Microtuber-derived plants were generally single-stemmed. Severe physiological ageing treatment ($>$2500 degree-days) had no effect on microtuber sprout development, stem number, tuber number and only minimally influenced tuber weight of microtuber-derived plants. Decreasing field in-row planting density from 30 to 10 cm reduced tuber weights and numbers per plant but increased them on a per hectare basis. Economic analysis indicated that optimum planting density varied depending on plantlet cost. The optimum planting density was 10 cm if the cost of the plantlet was $0.10 or less, 20 if plantlet cost were from $0.10 and $0.20 and 30 cm for plantlet cost greater than $0.20. A potato seed tuber certification program adapted to the needs and constraints of Egypt is presented.

Thesis (MScAgric)--Stellenbosch University, 2014.<br>ENGLISH ABSTRACT: The potato can be considered as one of the most important food crops in many African countries. The potential of this crop is reflected in the large increase in area of production where Africa showed the highest rate of growth within the developing world over the past twenty years. The multiplication rate of potatoes is very low compared to other crops. Therefore it is essential to investigate methods of increasing the number of minitubers produced from disease free in-vitro plantlets. There is a number of potato propagation procedures that are currently being used worldwide to multiply seed potatoes. As aeroponics is still a relatively new technique that has not been researched extensively for the production of minitubers, a study relating to the production practises including the nutritional requirements of potato minitubers produced in a aeroponic system were undertaken. Potato plantlets, cv BP1, were grown aeroponically at two different densities (20 and 30 plants/m2) and four harvest intervals (7, 10, 14 and 18 days). The interaction between harvesting intervals and plant densities did not influence plant growth, minituber quality or yield. Best results were realised when harvesting every 7 days with a higher total tuber number over the growing period. Harvest interval also influenced the phosphorus and copper concentration in minitubers. To study the effect of Calcium (Ca) application rate, potato plantlets of cultivars Up-to-date, Mnandi, Buffelspoort and BP1 were grown at four different Ca levels (8.40, 6.75, 5.10 and 3.45 meq/L). The interaction between Ca application levels and cultivars significantly influenced the percentage stolon branching. BP1 had more stolons at the lowest Ca application level and Buffelspoort had more stolons at the full Ca application levels. However, low Ca treatments produced the highest yield. The minituber number and weight harvested were three times more for Mnandi. An aeroponic study on the irrigation frequency (20, 30, 40 and 50 minutes interval) was conducted on four potato cultivars (Up-to-date, Mnandi, Buffelsoort and BP1). Significant differences were noted in the interaction between irrigation frequencies and cultivars for the percentage tuberised plants and stolon and tuber dry mass. When irrigated every 40 minutes, 48% of the Buffelspoort plants produced tubers. Plant height was also significantly affected by the interaction between irrigation frequencies and potato cultivars, with Mnandi producing taller plants when irrigated every 30 minutes. Total tuber number and tuber fresh and dry weight was higher at the irrigation frequency of 20 minutes. The interaction between irrigation frequencies and cultivars on the response to macro and trace elements was not significant for sodium and iron but was for phosphorus, potassium, calcium, zinc and aluminium. A field study was conducted in a greenhouse where potato seed of BP1 obtained from the first trial were graded into different sizes (Small: >20, medium: 20–40 and large: > 40 mm of diameter) and stored at 3 different temperatures (3, 16 and 25oC) for 2 supplementary months before being planted. Sprouting capacity was mostly influenced by temperature regardless of other factors applied to potato seed minitubers such as harvest intervals and sizes. The higher storage temperature of 25oC resulted in tubers with a higher number of sprouts, longer sprouts and with a higher sprouting capacity.<br>AFRIKAANSE OPSOMMING: Aartappels is een van die belangrikste voedselgewasse in baie lande in Afrika. Die potensiaal van die gewas word gereflekteer in die groot toename in produksie areas, met Afrika wat die vinnigste van al die ontwikkelende lande gegroei het die laaste 20. In vergelyking met ander gewasse is die tempo van planvermeerdering by aartappels baie stadig. Dit is dus essensieel om metodes te ondersoek wat sal help om die aantal miniknolle wat per in vitro plantjie verkry kan word te verhoog. Daar is heelparty plant vermeerderings prosedures wat tans wêreldwyd gebruik word om saad aartappels te vermeerder. Aangesien aeroponika nog steeds ʼn relatiewe nuwe tegniek is wat nog nie ekstensief ondersoek is vir die verbouing van miniknolle nie, is ‘n studie geloods om te kyk na die produksie praktyke, wat insluit die voedingsbehoeftes van aartappel miniknolle in ʼn aeroponika sisteem. Aartappel plantjies, kultivar, BP1, is aeroponies verbou by twee plant digthede (20 en 30 plante/m2) en vier oesintervalle (7, 10, 14 en 18 dae). Die interaksie tussen oesintervalle en plantdigtheid het geen effek gehad op plant groei, miniknol kwaliteit of opbrengs nie. Die beste resultate is verkry waar die knolle elke 7 dae geoes is met ‘n hoër totale aantal knolle oor die groeiseisoen. Die oesinterval het ook ‘n effek gehad op die fosfaat en koper konsentrasie van die miniknolle. Om die effek van die Kalsium (Ca) toedieningspeil te ondersoek is aartappel plantjies; kultivars Up-to-date, Mnandi, Buffelspoort en BP1 gekweek by vier verskillende Ca peile (8.40, 6.75, 5.10 en 3.45 meq/L). Die interaksie tussen Ca toedienings peile en kultivars het ‘n beduidende effek gehad op die persentasie stolon vertakking. BP1 het meer stolons gehad by die laagste Ca toedieningspeil en Buffelspoort het meer stolons gehad by die volle Ca toedieningspeil. Die hoogste opbrengste is egter waargeneem by die laagste Ca toedieningspeil. Die aantal miniknolle en oes massa was drie keer meer vir Mnandi. ‘n Aeroponiese studie op die besproeiingsfrekwensie (20, 30, 40 en 50 minuut intervalle) is gedoen met vier aartappel kultivars (Up-to-date, Mnandi, Buffelsoort en BP1). Beduidende verskille is opgemerk in die interaksie tussen besproeiings frekwensie en kultivars vir die persentasie plante met knolle en stolon en knol droë massa. Met besproeiings elke 40 minute het 48% van die Buffelspoort plante knolle produseer. Plant hoogte is ook beduidend beïnvloed deur die interaksie tussen besproeiingsfrekwensie en aartappel kultivar met Mnandi plante wat hoër was wanneer dit elke 30 minute besproei is. Die totale aantal knolle en knol vars- en droë massa was hoër wanneer daar elke 20 minute besproei is. Die interaksie tussen besproeiings frekwensie en kultivars op die makro- en mikro element inhoud van die knolle was nie beduidend vir natrium en yster nie, maar wel vir fosfaat, kalium, kalsium, sink en aluminium. ‘n Potproef is gedoen in ‘n kweekhuis waar aartappel saad van BP1 verkry vanaf die eerste proef nadat knolle verdeel is in verskillende grootte klasse (klein: < 20mm, medium: 20-40mm en groot: >40mm) en gestoor is by drie verskillende temperature (3, 16 en 25oC) vir 2 addisionele maande voor plant. Spruit ontwikkelings kapasiteit was meestal beïnvloed deur temperatuur ten spyte van ander behandelings soos oes intervalle en knol grootte. Die hoër bergings temperatuur 25oC het aanleiding gegee tot knolle met ‘n hoër aantal spruite, langer spruite en ‘n hoër spruit ontwikkelings kapasiteit.

Abstract:
Poor quality seed is the major constraint limiting both the productivity of potato crops and the expansion of the potato industry in Vietnam. Despite numerous attempts to establish a certified seed system, the most practical solution is to import clean foundation seed of the desired variety and physiological age. With imports from Europe and North America proving to be immature and too expensive, Western Australia (WA) has emerged as a potential source of high quality seed. While seed imports from WA are unique in that the varieties imported have been selected by researchers in Vietnam as being suited to the agro-ecological environment in the Red River Delta (RRD), no assessment of the economic benefits to smallholder potato farmers from the use of WA potato seed has been undertaken. In 2006/08, the yield and profitability of three potato varieties Eben, KT3 and Atlantic in two locations were compared where the crops had been derived from new seed imported from WA (VN0), seed derived from crops cultivated in the RRD after one generation (VN1) and two generations (VN2). There was a significant difference in the yield produced between the three different seed sources but not between the locations. For all varieties, and in both years, the yield decreased with the number of multiplications in Vietnam. Furthermore, the marketable yield declined significantly from the first crop (VN0) to the third crop (VN2). The decline in yield and tuber quality with each successive generation was associated with an increase in PVY and PVX infection. Not unexpectedly, differences in yield and marketable yield between the seed generations had a significant impact on the gross income for each variety.VN0 seed of all varieties produced the highest gross income (VND 2.4 to 4.1 M/sao) compared to VN1 (VND 1.9 to 3.1 M/sao) which was significantly higher than VN2 (VND 1.4 to 2.4 M/sao). However, while high quality seed is more productive, it is also more expensive. As a result, significant differences were observed between the seed costs. VN0 seed was almost two times more expensive (VND 10,500 – 11,000 per kg) than VN1 and VN2 seed (VND 6,000 – 6,500 per kg). Despite the higher costs, VN0 seed provided the highest net incomes compared to VN1 which was significantly higher than VN2. Farmers who retained seed received a higher net income (VND 0.13 – 0.6 M/sao) than those who did not retain seed.

Abstract:
Poor quality seed is the major constraint limiting both the productivity of potato crops and the expansion of the potato industry in Vietnam. Despite numerous attempts to establish a certified seed system, the most practical solution is to import clean foundation seed of the desired variety and physiological age. With imports from Europe and North America proving to be immature and too expensive, Western Australia (WA) has emerged as a potential source of high quality seed. While seed imports from WA are unique in that the varieties imported have been selected by researchers in Vietnam as being suited to the agro-ecological environment in the Red River Delta (RRD), no assessment of the economic benefits to smallholder potato farmers from the use of WA potato seed has been undertaken. In 2006/08, the yield and profitability of three potato varieties Eben, KT3 and Atlantic in two locations were compared where the crops had been derived from new seed imported from WA (VN0), seed derived from crops cultivated in the RRD after one generation (VN1) and two generations (VN2). There was a significant difference in the yield produced between the three different seed sources but not between the locations. For all varieties, and in both years, the yield decreased with the number of multiplications in Vietnam. Furthermore, the marketable yield declined significantly from the first crop (VN0) to the third crop (VN2). The decline in yield and tuber quality with each successive generation was associated with an increase in PVY and PVX infection. Not unexpectedly, differences in yield and marketable yield between the seed generations had a significant impact on the gross income for each variety.<br>VN0 seed of all varieties produced the highest gross income (VND 2.4 to 4.1 M/sao) compared to VN1 (VND 1.9 to 3.1 M/sao) which was significantly higher than VN2 (VND 1.4 to 2.4 M/sao). However, while high quality seed is more productive, it is also more expensive. As a result, significant differences were observed between the seed costs. VN0 seed was almost two times more expensive (VND 10,500 – 11,000 per kg) than VN1 and VN2 seed (VND 6,000 – 6,500 per kg). Despite the higher costs, VN0 seed provided the highest net incomes compared to VN1 which was significantly higher than VN2. Farmers who retained seed received a higher net income (VND 0.13 – 0.6 M/sao) than those who did not retain seed.

Abstract:
In the highlands of the Northern Philippines, a model of long-term relationships between potato farmers and their preferred seed suppliers is proposed. In the absence of any certified seed system that might provide some guarantee of seed quality, farmers prefer to transact with those seed suppliers with whom they have had some favourable prior experience. Such suppliers provide both the best quality seed and, since most farmers must borrow the capital to purchase the seed, the most favourable terms of repayment. As there is much uncertainty in the exchange, the farmer's relationship with their preferred seed supplier is based on trust. However, since the farmer's satisfaction with the exchange cannot be ascertained until after purchase, trust is antecedent to satisfaction. As satisfaction is derived from the economic benefits the farmer obtains, satisfaction will lead to the farmer's desire to maintain the relationship. Satisfaction is enhanced both by the seed supplier's willingness to extend credit and to provide information. As there is much variation between alternative seed supplier's offer quality, satisfaction will result in the farmer becoming more dependent upon that seed supplier who makes the best offer. Furthermore, having provided the farmer with financial assistance, seed suppliers will find that they have constrained their opportunities to use coercive influence strategies, for in the absence of any formal contract, farmer's may readily default on the loan. The use of coercive influence strategies will reduce both the farmer's trust in their preferred seed supplier and the farmer's desire to maintain the relationship.While trust is more important in the transitional economies, critical problems emerge with the use of standardised item measures and scales developed in the industrial countries. Cultural specific adjustments are necessary to ensure social constructs such a trust are functionally equivalent. However, in the context of long-term relationships where satisfaction is also cumulative, introducing measures of both economic and social satisfaction have the potential to overlap with the generally accepted measures of trust.

Abstract:
The optimization of the protocols of micropropagation including micro- and minitubes development processes is carried out as a part of the program to increase the effectiveness of health-improved potato seed material production. The collection of Krasnoyarsk RIA consists of potato cultivars being most popular in the Krasnoyarsk Territory. A large amount of work to increase the reproduction index does not allow them to be carried out involving all the stocked genotypes. To select the most commercially promising varieties, a tasting of potato tubers was carried out. Both classical statistic methods and those recommended by experts as more representative, according to recent data, for processing the results of expert evaluations of products were used in the present study. Kendall's coefficient of concordance showed middle consistency of expert evaluations (W = 0,31, p&lt;0,01). Based on Cronbach's alpha criterion the panelist making the largest contribution to the evaluation unbalance were detected. That criterion also made it possible to point out the cultivars differed from others by unbalance in taste estimation of them: Meteor, Gala, Tuleevskiy, Aramis. According to the sum of Friedman's ranks, five cultivars with the best taste qualities, combined with great demand among agricultural producers, were selected: Kolomba, Tuleevskiy, Rozara, Tanay, Gala.

Abstract:
Onion (Allium cepa L.) is one of the most commonly used vegetable crops for human consumption. To control weeds in onion crops, herbicides are used with a pre-emergence application time for crops and weeds (PRE-EM herbicides), as well as those with a post-emergence application time for crops and weeds (POST-EM herbicides). Potatoes (Solanum tuberosum L.) are grown on an area of 25 million hectares worldwide. About 70% of the area under potatoes is in Europe, where 80% of the total production is produced. Field research on the floristic composition of weeds was conducted during May 2024 in onion and potato crops at three different locations. In onion and potato crops, 17 weed species belonging to 12 families were identified during field research in 2024. The aim of the work is to determine the dominant weed species in these vegetable crops that limit the production and yield of these crops. The analysis determined that the most common weeds present in onion and potato crops are the following: Abutilon theophrasti, Ambrosia artemisiifolia, Chenopodium album, Datura stramonium, Sorghum halepense. Thus, the analysis of the total biological spectrum in the studied area indicates the dominance of annual plants from the therophyte category 70.58% (12 species), among which the most abundant are T4 therophytes with 47.06% (8 species) that germinate in spring, and the seeds ripen in late summer. In the analyzed weed flora, as many as five plants (29.41%) have the status of intensive, namely: Abutilon theophrasti, Amaranthus retroflexus, Ambrosia artemisiifolia, Polygonum lapathifolium and Sorghum halepense.

Agriculture is an important area that contributes to food security at the national level, and at the EU level, Romania plays an important role in the market for agricultural products. Potatoes, the most consumed vegetable product in Romania, will show a decrease in both areas, by around 57% in 2021 compared to the reference year 2014, and total production by 60%. Calculating the Gini coefficient, it can be seen that in the case of imports, the degree of concentration is low, while in the case of exports, the degree of concentration is high. Applying the simple linear regression, potato imports are strongly influenced by the domestic consul.

The agro-industrial complex needs to achieve a stable growth in agricultural production, including by increasing the sown area for spring wheat and potatoes, using new domestic varieties of seeds and improving cultivation technologies. An important task facing agricultural producers is the import substitution of basic food products with domestic products and the use of Russian-bred seeds instead of foreign ones. Over the past 2019, the area under grain crops increased by 101.2% against the level of 2018, including under spring wheat crops by 34.1%. Due to the cultivation of potatoes on personal and peasant farms, the production area under potatoes decreased by 63.3% compared to 2018.

Full text
Abstract:
Abstract Hydrogen Sulphide (H2S) is a colourless, flammable and highly toxic gas with a strong odour of rotten eggs that is found in many reservoir fluids and aquifers in the world. This gas is commonly a result of "reservoir souring" – a process which increases the H2S concentration. Increasing amounts of this gas pose serious health, safety and environmental concerns. This can result in significant costs associated with replacement of downhole and surface equipment and increased processing costs, but more lethally a potential loss of life. Many reservoirs particularly those undergoing waterflooding face increasing levels of hydrogen sulphide (H2S) production with time. H2S is a highly toxic gas that can be fatal even at low concentrations. Being able to predict the risk potential of a particular reservoir to increasing H2S production with time would be highly valuable. The objective is to determine apriori whether a reservoir would likely see dangerously high levels of H2S being produced during the lifetime of the reservoir, and if so, be a catalyst in supporting further investigation and mitigation of H2S early in the reservoir development. There is very little published field data with regards to reservoir souring, hence a purely data driven model would not be possible to create. However, we do have a good understanding of the reaction kinetics that goes into the biological process that generates H2S. To this end the best modelling paradigm that can assimilate sparse data with first principles dynamics is fuzzy logic. A fuzzy logic model has been built around the reaction kinetics and then conditioned to the published field data. The model created matches the published field data fairly well. It is now a ready tool that can be used by engineers to make a quick assessment of their reservoirs before going into full blown expensive sampling and laboratory analysis. The novel aspect of this paper is being able to use fuzzy logic to combine the first principles chemistry together with sparse data to produce a model that can be used practically. Fuzzy Logic has been out of the news of late as machine learning and neural networks are the current hot potatoes, however it is often overlooked that fuzzy logic can still be used in low dimensional cases where only sparse data is available.

Barriers to Application of Weather and Climate Information in Smallholder Vegetable Farming in Benguet. Philippine Institute for Development Studies, 2020. https://doi.org/10.62986/dp2020.14.

Full text
Abstract:
Benguet provinces comparative advantage in the cultivation of high value crops such as cabbage, carrots, and potatoes are evident in the high volume of production experienced year on year. This may be attributed to the provinces favorable weather and climate. Climate change, however, may threaten the stability of the mountain farming systems in the coming years without proper measures for adaptation. This paper aims to understand the current barriers to the access and use of weather and climate information in agricultural decisionmaking as a means to cope with the changing climate. It was found that, while farmers see the value of using weather and climate information, there is a lack of localized weather and climate information applicable to the microclimate of Benguet. The provision of information must also be supported with other interventions, such as access to low cost credit, to provide the other lacking resources farmers need to enact the optimal decision alternative.

Gender mainstreaming in local potato seed system in Georgia. International Potato Center, 2020. http://dx.doi.org/10.4160/9789290605645.

Full text
Abstract:
This report presents the study findings associated with the project “Enhancing Rural Livelihoods in Georgia: Introducing Integrated Seed Health Approaches to Local Potato Seed Systems” in Georgia. It also incorporates information from the results of gender training conducted within the framework of the USAID Potato Program in Georgia. The study had three major aims: 1) to understand the gender-related opportunities and constraints impacting the participation of men and women in potato seed systems in Georgia; 2) to test the multistakeholder framework for intervening in root, tuber, and banana (RTB) seed systems as a means to understand the systems themselves and the possibilities of improving gender-related interventions in the potato seed system; and 3) to develop farmers’ leadership skills to facilitate women’s active involvement in project activities. Results of the project assessment identified certain constraints on gender mainstreaming in the potato seed system: a low level of female participation in decision-making processes, women’s limited access to finances that would enable their greater involvement in larger scale potato farming, and a low awareness of potato seed systems and of possible female involvement in associated activities. Significantly, the perception of gender roles and stereotypes differs from region to region in Georgia; this difference is quite pronounced in the target municipalities of Kazbegi, Marneuli, and Akhalkalaki, with the last two having populations of ethnic minorities (Azeri and Armenian, respectively). For example, in Marneuli, although women are actively involved in potato production, they are not considered farmers but mainly as assistants to farmers, who are men. This type of diversity (or lack thereof) results in a different understanding of gender mainstreaming in the potato seed system as well. Based on the training results obtained in three target regions—Akhalkalaki, Akhaltsikhe, and Marneuli—it is evident that women are keen on learning new technologies and on acquiring updated agricultural information, including on potato production. It is also clear that women spend as much time as men do on farming activities such as potato production, particularly in weeding and harvesting. However, women are heavily burdened with domestic work, and they are not major decision-makers with regard to potato variety selection, agricultural investments, and product sales, nor with the inclusion of participants in any training provided. Involving women in project activities will lead to greater efficiency in the potato production environment, as women’s increased knowledge will certainly contribute to an improved production process, and their new ideas will help to improve existing production systems, through which women could also gain confidence and power. As a general recommendation, it is extremely important to develop equitable seed systems that take into consideration, among other factors, social context and the cultural aspects of local communities. Thus, understanding male and female farmers’ knowledge may promote the development of seed systems that are sustainable and responsive to farmers’ needs and capacities.
