Download or read book Russet Burbank Response to Nitrogen Fertilization and Planting Date written by Robert Kim Thornton and published by . This book was released on 1997 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies addressed impacts of planting dates and variable N applications on numbers and size of Russet Burbank stems and stolon nodal position in relation to tuber growth and levels of hollow heart (HH) and brown center (BC). Low preplant N regimes produced larger tubers and final yields, and less HH and BC than the high N regime. Reduced preplant N regimes also lowered tuber grade and specific gravity. Negative effects of the low preplant N regime were offset by delaying planting or beginning application of post-BC initiation N earlier. Stem size influenced plants season-long and affected tuber size and yield, early- and late-season HHBC development, and HHBC dissipation and severity. These responses were related more to stem and tuber growth than to weather. Levels of HHBC increased as similar-sized tubers grew. Tubers expressed less HHBC, regardless of size or stolon nodal position, when growing at different rates or times than most other tubers. HHBC development began, declined, and increased at different times during the season. Tuber susceptibility to HHIBC increased throughout the season in association with increased stem size and/or reduced stems per plant. Plants with 3 or more stems produced higher tuber yields but less HHBC than plants with fewer than 3 stems. Large-stem tubers from 1- and 2-stem plants grew faster and were more susceptible to HHBC than large-stem tubers on plants with 3 or more stems. Delayed plantings reduced HHBC and increased stem numbers per plant, thereby reducing the proportion of high yielding, HHBC susceptible stem-types. Delayed plantings did not affect the growth stage(s) during which tubers became susceptible. Preplant N regime did not affect stem numbers per plant, but HHBC was reduced by low regimes. Low preplant N plants exhibited equal or increased tuber growth rates, but reduced vine biomass compared to high preplant N plants; consequently, large stems, especially from single- and double-stem plants, showed more BC dissipation, resulting in less early-season HHBC compared to high preplant N plants. Late-season HFIBC was less affected by N treatment.

Download or read book Management of nitrogen and water in potato production written by A.J. Haverkort and published by BRILL. This book was released on 2023-08-28 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potato is very sensitive to water and nitrogen applied during growth, affecting its profitability and impact on the environment. Recent scientific and technical breakthroughs enable us to make best use of water and nitrogen. This book shows how scientific knowledge works in practice, now and well into the new millennium. This systematic and comprehensive book on crop, soil and water technologies will assist producers to achieve optimal production with maximum benefit to themselves and to the environment. Crucial questions, such as: - Which sampling techniques of plants and soil are available and which should I use? - What do the data gathered mean and how do they assist me in water and nitrogen application? - Which decision support systems exist for rain-fed, irrigated, precision or organic farming? are answered. The book updates and interprets knowledge in a simple, easily understandable way. It is intended for farmers, farmers' consultants, researchers and decision makers and is also recommended for students in soil science and agronomy.

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.
