Download or read book Sustainable Potato Production Global Case Studies written by Zhongqi He and published by Springer Science & Business Media. This book was released on 2012-05-24 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potato (Solanum tuberosum L.) is grown in over 100 countries throughout the world. As a staple food, potato is the fourth most important crop after rice, wheat, and maize, and has historically contributed to food and nutrition security in the world. Global interest in potato increased recently as world food prices soared, threatening the global food security and stability. Unlike major cereals, potato is not a globally traded commodity, and prices are usually determined by local production costs. Thus, potato is increasingly regarded as a vital food-security crop and as a substitute for costly cereal imports. With such importance, the 29 chapters in the edited book address the issues of sustainable potato production. This book begins with an introduction on sustainable potato production and global food security, and then presents eight case studies selected globally and covering different issues relevant to sustainable potato production in both developed and developing countries.

Download or read book Decision support systems in potato production written by D.K.L. MacKerron and published by BRILL. This book was released on 2023-08-28 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Models of crop growth and development were conceived originally for scientific purposes. Typically, they describe the mechanisms of crop production, development from emergence through tuber initiation to senescence determined by temperature and day-length. Growth is driven by solar radiation intercepted by the foliage. Yields are enhanced by the availability of water and nutrients and may be reduced by pests, diseases and weeds. The scientific models describing the processes involved are leaving the research institutes and increasingly are becoming a means of knowledge transfer for students, and most importantly, to growers and their intermediaries such as extensionists and consultants. Many decision support systems (DSS) have a mechanistic model core that assures their robustness and reliability. This book gives an overview of model-based DSS in potato production. Decision support systems are used by the processing industry to guide them to promising production areas and by breeders to identify the ideal genotype for such environments. Consultants and soil laboratories use them as well as farmers to optimize the use of nitrogen, water and chemicals to control insects, nematodes, late blight and weeds. The systems, making use of models and sensing techniques, improve yield and quality while allowing their users to improve the efficiency of use of resources, thus generating positive effects for profits and for the environment. The book also gives examples of new introductions of DSS and farmers responses. The book is intended for researchers wanting to bring their models to practice, students to learn bout DSS, intermediaries and growers to improve the performance of the potato industry or of other commodities for which potato serves as an example.

Available in PDF, EPUB and Kindle. Book excerpt: The study focused on optimizing potato production and nitrogen (N) management practices on sandy soils. The research covered several key areas, including the effect of N rates on yield and nitrogen use efficiency (AE), variations in dry matter and N uptake patterns among potato varieties, the use of visible-near infrared (vis-NIR) spectroscopy to estimate leaf N status, and the influence of soil organic matter (SOM) on potato productivity in sandy soils. The study began with a systematic review and meta-analysis, which examined the relationship between N rates and yield, as well as N rates and agronomic N use efficiency. The analysis showed that N fertilization had a significant effect on yield, with an optimal N rate of 236 kg N ha-1. Additionally, it revealed a linear decrease in agronomic N use efficiency as N fertilization increased. Furthermore, investigating potato varieties, the research found variations in dry matter and N uptake patterns in both vines and tubers. Different potato varieties responded differently to N fertilization, affecting vine response patterns. However, variations in tuber biomass were primarily attributed to the specific potato varieties rather than N fertilizer rates. The thesis also validated the use of vis-NIR spectroscopy as a cost-effective and efficient method for monitoring leaf N status in potatoes. A model using partial least square regression (PLSR) was developed, demonstrating high predictive performance in estimating total N content in leaves. However, the accuracy of the model was decreased when total N contents exceeded 6 %. Finally, the study examined the impact of SOM levels on potato productivity in sandy soils. Soil samples from various fields were collected, and a greenhouse study was conducted. The results indicated that SOM positively influenced plant productivity, with significant effects observed in multiple productivity metrics. It was also found that N mineralization acted as a partial mediator of the SOM effect on productivity, demonstrating that SOM enhances plant productivity through mechanisms beyond simple N acquisition. In summary, the thesis provides valuable insights for potato production in the Midwestern agroecological region. The findings emphasize the importance of variety-specific responses to N fertilization, validate vis-NIR spectroscopy as a tool for monitoring leaf N status, and highlight the importance of SOM on potato productivity in sandy soils. These findings can help farmers and researchers optimize potato production, reduce N losses, promote sustainability, and maximize resource utilization in agriculture.
