Mineral nutrition and fertilization of sweet potatoNutrição mineral e adubação da batata-doce
(2020-01-01)
Sweet potato (Ipomoea batatas L.) is a versatile crop, but it is often grown in marginal and low-fertility areas, which reflects storage root yields far below its potential. For this reason, balanced liming and fertilization ...
INFLUENCE OF ORGANOMINERAL FERTILIZATION IN THE DEVELOPMENT OF THE POTATO CROP CV. CUPID
(Univ Federal Uberlandia, 2019-01-01)
The potato crop is very demanding regarding the presence of nutrients in the form readily available in soil solution and the climatic conditions to ensure satisfactory production of tubers. Each potato cultivar has specific ...
Use of seasonal forecasts of sea surface temperature anomalies for potato fertilization management. Theoretical study considering EPIC model results at Valdivia, Chile
(ELSEVIER SCI LTD, 2004)
The use of perfect and imperfect forecasts of sea surface temperature anomalies (SSTA) in the Equatorial Pacific for potato fertilization strategies is presented in this study. The applications of SSTA forecasts and the ...
Nitrogen balance for potato crops in the southeast pampas region, Argentina
(Springer, 2013-01)
The aim of this work was to build an N mass balance for the potato crop under irrigation conditions in the southeast pampas (Argentina) as a function of N rate and gravitational water. The experiment was developed in a ...
Biomass Accumulation and Nutritional Requirements of Potato as Affected by Potassium Supply
(2020-09-01)
Potassium (K) supply affects the growth and tuber yield of potato (Solanum tuberosum L.) as well as the uptake and removal of certain nutrients. However, information on this is scarce or inconsistent. Thus, this study was ...
Chlorophyll meter-based leaf nitrogen status to manage nitrogen in tropical potato production
(2021-01-01)
Potato (Solanum tuberosum L.) is a N intensive crop, and meeting its requirements with N fertilization is the primary practice to improve N recovery and achieve suitable tuber yield. A 3-site-year (SY) study was conducted ...
Yield and nitrogen use efficiency of sweet potato in response to cover crop and nitrogen management
(2018-09-01)
Selected cover crops can provide N to sweet potato (Ipomoea batatas [L.] Lam) crops cultivated in succession and reduce the need for mineral N application. This study was conducted to determine the growth, leaf N concentration, ...
Performance of conventional and enhanced-efficiency nitrogen fertilizers on potato tuber mineral composition and marketability
(2021-01-01)
BACKGROUND: Potato is an essential crop for global food security, and its cultivation requires a significant amount of readily available nitrogen (N) to ensure tuber quality. Therefore, managing N with enhanced-efficiency ...
Tuber Yield and Quality of Two Potato Cultivars in Response to Nitrogen Fertilizer Management
(2020-01-01)
In Brazil, the potato cultivar Agata is used for fresh market, while the cultivar Markies is used for both fresh market and frying industry. However, these cultivars may respond differently to nitrogen (N) management. Thus, ...
Fertilization management strategies for 'Agata' potato production
(Assoc Brasileira Horticultura, 2021-10-01)
Fluctuations in potato prices and invariably rising production costs need sustainable fertilization strategies. For this purpose, two experiments were conducted in the southwestern region of Sao Paulo state to evaluate ...
