Concerning public health are deficits in zinc, folate and the B vitamins, among other micronutrients. Micronutrient malnutrition, often referred to as hidden hunger, represents one of humanity’s most pressing challenges. Iron deficiency anaemia affects more individuals globally than any other prevalent disorder. However, iron supplementation can exacerbate infectious diseases, necessitating careful evaluation of iron therapy policies. In this review, we explore biofortification strategies to combat hidden hunger, considering recent medical and nutritional advancements. Enhancing iron content in edible plant parts can improve human nutrient status through crop consumption. Mineral and vitamin density in staple foods, particularly for impoverished populations, can be increased using traditional plant breeding or transgenic approaches, collectively known as biofortification. Microbial iron biofortification is especially valuable in developing countries where expensive supplements are unaffordable.

Among the most notorious diseases is late blight, caused by <i>Phytophthora infestans</i>, famously responsible for triggering the Irish Potato Famine in the 1840s. Late blight swiftly devastates potato foliage and tubers, particularly in damp, humid conditions. Another common disease is early blight, attributed to <i>Alternaria solani</i>. This disease affects various parts of the potato plant—leaves, stems, and tubers. It mainly shows up in the form of dark stains around the center of a bull’s eye on the leaves, bringing down both the yield and the crop quality. A model consisting of a Convolutional Neural Network - Long Short-Term Memory (CNN-LSTM) enhanced for potato disease detection was proposed in our paper. The dataset used was Z-score standardized before the training and testing process using the proposed CNN-LSTM model was started. The performance of the implemented model, CNN-LSTM, was analyzed alongside five traditional machine learning algorithms, namely Random Forest (RF), Extra Trees (ET), K-Nearest Neighbours (KNN), Adaptive Boosting (AdaBoost), and Support Vector Machine (SVM).

Contract farming in high-value crops such as potato is seen as one of the several ways to develop new market linkages with the farmers and improve farming income consistently through the dissemination of new production and post-harvest processing technologies. In this context, a comparative analysis of contract farmers associated with the PepsiCo company and non-contract farmers growing potato for local markets is carried out in Punjab to determine the empirical gains that accrue to contract farmers and the role of contract farming in farm diversification. The findings revealed that the company procures potatoes at farmers' fields through quad-partite and written contractual agreements, extends extension and training facilities at the farmers' doorstep, and provides yield-based incentives to the farmers. Contract farmers earned more profits than their counterpart non-contract farmers mainly due to their better price realization, although contract farmers had lower yields and higher cost of production than non-contract farmers. However, the imposition of the condition of growing at least 4 ha of area under potatoes led to the exclusion of small farmers and did not lead to diversification away from traditional crops to high-value crops such as potato. The study argues that the Punjab government needs to play a proactive role in facilitating the participation of small farmers through group contracts and Farmer Producer Organizations (FPOs) to enhance farmers' income and crop diversification through potato contract farming.</p>","PeriodicalId":20378,"journal":{"name":"Potato Research","volume":"25 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141567560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, analyzing the potential yield of potato as affected by global warming is of great significance to direct the production of crops worldwide. However, up to now, most research reports estimated the potential yield of potatoes by models which are based on the theory of production functions while there are few theoretical studies on the time-series approach based on stationary stochastic processes. Thus, in this paper, both average and top (national) yields of potato between 2021 and 2030 are projected creatively using an auto-regressive integrated moving average and trend regression (ARIMA-TR) model basing the projection on historic yields from 1961 to 2020 to explore the potential yield of the crop in the future; the effects of global warming on both average and top (national) yields of potato from 1961 to 2020 are analyzed using binary regression models in which global mean temperature is treated as the independent variable and the yield as the dependent variable, to reveal how climatic events drive the variation trend of these two types of yield. Our results show that between 2021 and 2030, the average yield of potato is projected to be from 21,234 to 23,773 kg/ha while the top yield ranges from 50,240 to 51,452 kg/ha; the average will approach from 42.26 to 46.20% of the top, or the gap between these two yields will be gradually narrowed in the ensuing decade; from 1961 to 2020, global warming exerts a positive effect on the average yield of potato with a quadratic function (<i>R</i>-squared = 0.772 and <i>F</i> = 96.417) more than on the top yield with an inverse function (<i>R</i>-squared = 0.568 and <i>F</i> = 76.201), which partly makes the gap between these two types of yields shrink. Our study concludes that for potato by 2030, the opportunities for improving global production should be dependent on both high- and low-yield countries as the average yield is in the main body of an <i>S</i>-shaped curve in the evolutionary trend in the long run. These insights provide the academic circle with innovative comprehension of the potential yield of potato for global food security under climate change.</p>","PeriodicalId":20378,"journal":{"name":"Potato Research","volume":"51 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141567561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this perspective, optimization techniques are vital in improving disease classification accuracy, thus helping in early detection and timely intervention.
