Production and Marketing of Potato in Middle Gujarat

Background: This paper presents the economic analysis of potato cultivation in middle Gujarat. The area under total vegetable and production of vegetables in the state has increased over the years. The study focuses on production and marketing of potato in middle Gujarat. Methods: Primary data were collected using pre-tested schedule. The cost of production was calculated using cost concept and marketing efficiency was calculated using Acharya’s formula. Result: The study found that the cost C2 was ₹ 208587.5 per hectare for potato cultivation. Yield of potato was found to be 242.5 quintal per hectare, while gross income was ₹ 247370.4 per hectare. The net return was observed to be at ₹ 38782.9 per ha for potato cultivation. Benefit cost ratio over cost C2 was observed to be at 1.19. There were two marketing channels found in potato in study area. The market efficiency was found higher in channel I. Unavailability of labour, long distance of input market and increasing prices of inputs were the major production constraints, while low price received by farmer, delayed in payment and higher cost of transportation were the major marketing constraint found in study area.

A Scale to Measure the Level of Management Orientation of the Members of Farmer Producer Company with Reference to Potato Production in Assam, India

In the absence of a suitable scale to measure the management orientation of potato growers in relation to potato planning, potato production and potato marketing in Assam, there was a need to construct a management orientation scale. Therefore, effort was made to construct a scale to measure the level of management orientation of the members of the Farmer Producer Company with reference to potato production in Assam. A scale was developed with Likert’s summated rating technique. A list of 90 statements resulted after edition of 110 statements as per the fourteen criteria suggested by Thurstone and Chave. Statements were sent to 80 extension specialist working in various field of Assam Agricultural University for the critical evaluation of statements on a 3 point continuum. Based on the responses received from 60 out of 80 judges, the relevancy percentage (RP), Relevancy Weightage (RW) and Mean Relevancy Scores (MRS) were estimated. 74 items with RP > 60, RW > 0.60 and overall MRS > 2.0 were considered for item analysis. These items were administrated to 40 farmers for item analysis and items with ‘t’ value equal or greater than 1.75 were selected and those with ‘t’ value below 1.75 were rejected. Out of 74 statements, 30 statements were retained on the final scale through t-test item analysis. Thus, the instrument developed to measure the level of management orientation of the members of farmer producer company with reference to potato production in Assam consists of 20 positive and 10 negative statements. The dependability coefficient was determined using Rulon's formula and it was 0.8994. As a result, the developed scale was proven to be highly reliable. The scale developed to measure the level of management orientation of the members of Farmer Producer Company with reference to potato production in Assam is found to be reliable and can be utilized by researchers in similar studies. This scale will be very advantageous and convenient for researchers to examine the management orientation of potato growers in relation to potato planning, potato production and potato marketing.

Early Tuberization: A Heat Stress Escape Strategy in the Fresh Market Potato Variety Vanguard Russet

Early Tuberization: A Heat Stress Escape Strategy in the Fresh Market Potato Variety Vanguard Russet

Effect of Temperature, Relative Humidity, and Incubation Time on the Mycotoxin Production by Fusarium spp. Responsible for Dry Rot in Potato Tubers.

Potato is the fourth most consumed crop in the world. More than half of the crop is stored for three to nine months at cold temperatures (3-10 °C) for the fresh and seed market. One of the main causes of fresh potato waste in the retail supply chain is the processing of fungal and bacterial rots during storage. Dry rot is a fungal disease that mainly affects the potato crop during storage and is responsible for 1% of tuber losses in the UK. It is produced by Fusarium spp., such as Fusarium sambucinum and F. oxysporum, which can lead to the accumulation of mycotoxins in the potato tuber. Little is known about the impact of environmental factors on the accumulation of mycotoxins in potato tubers. Understanding the ecophysiology of these fungi is key to mitigating their occurrence under commercial storage conditions. Therefore, this work aimed to elucidate the effect of three different temperatures (5, 10, and 15 °C) and two different water activities (aw; 0.97, 0.99) on the ecophysiology and mycotoxin accumulation of F. sambucinum and F. oxysporum in a potato-based semi-synthetic medium. The mycotoxin accumulation was then studied in vivo, in potato tubers cultivated under organic farming conditions, stored for 40 days at 8.5 °C. Results showed that higher temperatures and aw enhanced fungal growth, lag time, and mycotoxin accumulation in vitro. Growth rate was 2 and 3.6 times higher when the temperature increased from 5 to 10 and 15 °C, respectively. Six different mycotoxins (T-2, HT-2, diacetoxyscirpenol, 15-acetoxyscirpenol, neosolaniol, and beauvericin) were detected in vitro and in vivo. T-2 was the most abundant mycotoxin detected in vitro, observing 106 ng of T-2/g media after 21 days of incubation at 10 °C and 0.99 aw. Due to the long period of time that potato tubers spend in storage, the fluctuations of environmental factors, such as temperature and relative humidity, could promote the development of fungal rot, as well as mycotoxin accumulation. This could result in important food and economic losses for the potato market and a threat to food safety.

Exogenous nicotinamide accelerates pyridine nucleotides metabolism and redox homeostasis: A novel strategy for extension of potato dormancy

The sprout of potatoes during storage threatens the post-harvest potato market supply chain. To reduce the massive economic losses in potato production industry, herein, the exogenous nicotinamide (NAM) was taken into consideration to maintain the potato quality. This study focused on the role of NAM on potato sprout development and revealed the possible mechanisms from the perspectives of energy and pyridine nucleotides metabolism. It was found that NAM delayed the sprouting and quality deterioration by down-regulating respiration rate and energy charge. Additionally, NAM stimulated the synthesis of nicotinamide adenine dinucleotide (NAD+) and nicotinamide adenine dinucleotide phosphate (NADPH) in pyridine nucleotides cycle, which maintained redox balance and reduced the burst of reactive oxygen species (ROS) at the sprouting site. Our findings provide a novel perspective on the possible strategies of NAM for improving the quality of fresh produce.

Primary Non-Inversion Shallow Tillage Versus Moldboard Plowing Prior to Growing Potatoes: Short-Term Impacts on Potato Yield and Soil Properties in Eastern Canada

Potato (Solanum tuberosum L.) production often requires intensive tillage with the moldboard plow (MP), which involves deeper soil tillage and turning of the soil to provide enough loose soil for proper tuberization. Although tillage with the MP allows better potato seedbed preparation and lower weed pressure, it is also associated with increased soil compaction, soil aggregate destruction, and increased soil organic matter (SOM) mineralization. The objective of this four-year (2019–2022) study conducted in 14 commercial fields was to compare the use of MP with primary non-inversion shallow tillage (ST) in terms of their effect on selected soil health indicators, soil moisture, potato petiole nitrate concentration, potato yield, and specific gravity. Commercial fields ranged from 1.5 ha to 19 ha where the main field was split in half, with one side tilled using MP (22.5–30 cm plowing depth) and the other half using ST (15–30 cm plowing depth). Soil and plant tissue samples were taken within four sub-replicates (91 m2) created per each treatment per each site and three to four sites were used as replicates per each year. Compared to MP, ST increased active carbon by an average of 9%, soil respiration by an average of 26%, and aggregate stability by an average of 8%. Biological N availability (BNA) increased by an average of 20% with ST, and the effect was statistically significant in three out of four years. Soil moisture at 20 cm depth tended to be higher with MP than ST in three out of four years. Although not statistically significant, when averaged across four years, potato petiole nitrate concentrations were 5% and 12% higher with ST than MP in samples collected at the flowering and post-potato flowering stages, respectively. Total and marketable potato yields, along with specific gravity, were comparable for the two tillage regimes. Signs of soil improvement were observed at the early stages of ST adoption. Marketable yield was negatively correlated with the soil nitrate levels measured during the growing season but was positively correlated with active carbon, aggregate stability, and soil moisture. Future studies could compare both tillage regimes over multiple growing seasons to assess their impacts over a full cycle of rotation. The novelty of the present study was that it was conducted in real-life conditions across large growers’ fields with different conditions and across four years.

Harnessing Soil Diversity: Innovative Strategies for Potato Blight Management in Central-Eastern Poland

Faced with increasing climate challenges, this pioneering study introduces groundbreaking approaches to ensure the resilience of potato crops in east-central Poland. Our research was aimed at developing an innovative, cost-effective system tailored to the diverse local conditions of this region. Conducted between 2018 and 2020, the study analyzed integrated and organic production systems across different soil types and potato varieties. The experiment was conducted using a randomized block design with three replications in two locations. Integrated production systems involve the strategic use of mineral fertilization and chemical protection to optimize crop growth and health, whereas organic production systems rely solely on natural inputs and biological pest control methods. Integrated practices, enhanced by mineral fertilization and chemical protection, notably delayed the onset of late blight by 16 days and extended the critical infection period by 17% compared to their organic counterparts. Remarkably, the integrated systems resulted in a 49% increase in total production and a 52% increase in commercial yields, demonstrating their effectiveness in enhancing crop resilience. Different potato varieties exhibit varied responses to cultivation systems, influencing both yield and disease resistance. Further investigation into these varietal responses can help optimize cultivation practices, leading to improved efficiency and sustainability in potato farming. Location and soil conditions have a significant impact on potato yield and the spread of potato blight. Specific soil properties such as pH levels, organic matter content, soil texture (clay, silt, and sand composition), moisture retention capacity, and nutrient availability are crucial in determining potato productivity and disease dynamics. Further research into these soil properties and the adaptation of varieties to local conditions can contribute to increased productivity and stability in potato production. This study not only paves the way toward sustainable agriculture but also highlights the crucial role of soil diversity in shaping resilient farming practices. Potato producers in the eastern-central region of Poland should implement integrated production systems using mineral fertilization and chemical plant protection, adapted to local soil conditions and potato varieties. These practices can delay the appearance of late blight and increase the total and marketable potato yield. Further research on soil properties and variety adaptation may increase production stability and efficiency. Promoting soil diversity and modern technologies will ensure resilient and sustainable agricultural production in the face of climate change.

A Complex Approach to Control Black Dot Disease in Potato

In recent years, skin blemish diseases of potato (including black dot (BD) caused by Colletotricum coccodes) have begun to be important for global potato marketing, since consumers often reject tubers with an imperfect appearance, which results in financial losses caused by the disposal of unwanted potatoes. Like for many non-fatal plant diseases, BD severity may depend on the immune status of plants influenced by other infectious agents. Using a set of 98 potato cultivars differing in their late blight (LB) resistance, we examined the correlation between the intensity of their infection with LB determined by their LB resistance and the occurrence of the BD disease under field conditions with a high background level of both diseases. Using LB-susceptible (Arizona) and moderately susceptible (Sante) cultivars, we also evaluated the effect of a crop protection against LB on BD development under the same field conditions. A strong negative correlation (r = −0.81, p < 0.05) between the LB resistance and the BD occurrence has been revealed. An experiment using the two cultivars, chemically protected against LB, showed a significant reduction in BD occurrence of 30% (cv. Arizona) and 20% (cv. Sante) compared to the untreated controls; the total yield and marketability of potatoes increased by 103.6 and 62.5% for cv. Arizona and by 65.9 and 43.8% for cv. Sante. The reduction in the LB affection of potato is one of the key factors improving the immune status of potato cultivars in relation to BD infection, so methods of LB protection should be included in a complex approach to BD control.

The results of this study show that the potato marketing margin of each institution in Modoinding sub-district is different between Manado, Bitung, and Kotamobagu channels. Farmer's share received by farmers in the Bitung channel is higher than farmer's share in the Manado and Kotamobagu channels, but farmers still get the same purchase price. Channel (farmer - intermediary - retailer - consumer). Farmers still get the same price and the costs of labor and transportation are borne by buyers, namely collectors and retailers.

Breeding for potato cyst nematode resistance in Solanum tuberosum

AbstractTwo species of potato cyst nematodes (PCNs), Globodera rostochiensis (Woll.) and Globodera pallida (Stone), threaten potato (Solanum tuberosum L.) production worldwide. PCNs are remarkably persistent in soil and can reduce potato yield significantly. The most sustainable approach to PCN control is deploying resistant cultivars. This review focuses on the knowledge needed to conduct a successful PCN resistance breeding program, including identifying resistance sources in wild species, introgressing them into cultivated potato, and sifting through clones to identify a marketable potato.

Study of potato variety numbers in the breeding process in the northern regions of Russia

In the conditions of the Arkhangelsk region in the nurseries of the breeding process the study of potato hybrids was carried out and the varieties with high yield, resistance to pathogens and various environmental factors were selected. In 2019, 759 hybrid samples of 9 populations were received from the breeding department of the All-Russian Research Institute of Potato Farming by A.G.Lorh with further study and selection of the best of them in the nurseries of the breeding process: hybrids of the 1st and 2nd year, preliminary and main trials of the 1st year. As a result of research and complex evaluation in the nursery of the main trial of the 1st year in the first dynamic digging (60 days after planting) in the group "medium early" hybrid 2553/1 stood out on the total and marketable yield exceeding the standard variety Kholmogorsky by 2.4 times, in the main harvest – only by 11%. In the group "medium early" in the main harvesting hybrid 2553/4 stood out exceeding the standard variety Elizaveta on the total yield by 7.4 t / ha, on marketable – by 3.2 t / ha. High total and marketable potato yields in the main harvest were obtained in sample 2462/3 (44.3 and 42.5 t/ha, respectively). Observations of potato plants during vegetation periods showed that no clone was affected by rhizoctoniose, microsporiosis and viral diseases. High resistance to late blight of potato hybrids in the first observation period and decrease of its resistance to the end of the vegetation period, before removal of haulm, was also revealed. This is probably due to low air temperature and significant precipitation during this period. Selection samples that showed high productivity and resistance to major diseases will be studied in further breeding process in order to create new varieties for cultivation in the conditions of northern regions of Russia.

DDDM Concept: Completeness and Reliability of Potato Market Data in the Republic of Kazakhstan

In the context of current global challenges, the usual course of development of economic markets, including the food market, is changing. The effectiveness of management depends on the quality of decisions based on the concept of Data Driven Decision Making, which relies on the use of data. In this connection, the issue of reliability and completeness of the data used becomes relevant. The purpose of this work is to analyze the data of official statistics on the potato market in terms of their completeness and reliability for decision making. The methods of statistical and comparative analysis were applied in the course of the study. As a result, inconsistencies were revealed in the data on the volume of harvest and the share of losses, which indicates unreliability or incompleteness of information. Measures to avoid the above mistakes were proposed.

Price Behaviour and Market Integration Amongst the Major Potato Markets in India

Variation in potato output over time causes wide price fluctuations, subjecting its producers to a high-risk situation. Using a monthly wholesale price of potato from January 2012 to December 2020, the current study examined the price behaviour of major potato-producing and consuming markets. The study employed correlation analysis, the Johansen Co-integration Test, the Vector Error Correction Model, and Granger Causality Test. As determined by the seasonality index, farmers received higher-than-average prices between June and December. Johansen's co-integration result demonstrated that all the selected markets were well integrated in the long run. The Patna market had the fastest adjustment rate (80 per cent), followed by the Mumbai market. Most states had uni-directional price transmission, with Patna being the only state to establish a bidirectional flow of potato prices with the Kolkata market. The Delhi market was discovered to be the key market influencing the prices of all other markets.

Identification and reproduction of dagger nematode, Xiphinema americanum, in potato

Summary Plant-parasitic nematodes limit potato production by feeding on roots, reducing tuber yield and quality, and resulting in poor growth. Dagger nematodes (Xiphinema spp.) can pose a significant threat to crop production even in low numbers. Dagger nematodes have been reported in North Dakota, USA, potato fields. In this study, a dagger nematode species was identified and its reproduction potential in 21 potato cultivars was evaluated. The dagger nematode was identified as X. americanum via morphometric measurements and DNA sequence analysis. At the molecular level, D2-D3 of 28S ribosomal RNA (rRNA) and internal transcribed spacer (ITS)-regions of rDNA were targeted. Sequencing data of D2-D3 (749 bp) showed 98.18% similarity with three isolates of X. americanum. ITS sequence (860 bp) analysis showed 97.68% similarity with an isolate of X. americanum but lower similarity with other species of Xiphinema. The phylogenetic analysis of ITS region further confirmed the species of dagger nematode as X. americanum. Using naturally infested soil, two glasshouse experiments were conducted to assess the reproduction rate of X. americanum on 21 potato cultivars belonging to four distinct market potato classes (yellow, red, white and russet). The reproduction rates were found to vary among the potato classes and cultivars. Numerically, X. americanum population density was higher in ‘Soraya’, whereas ‘Ranger Russet’, ‘Manistee’, ‘Kennebec’, ‘Russet Norkotah 278’, ‘Modoc’, ‘Pomerelle Russet’ and ‘Dakota Rose’ reduced nematode reproduction in both trials. This is the first study demonstrating the reproduction of X. americanum in potato cultivars and could be helpful to manage dagger nematodes.
