Leaf area index of potato crop under three nitrogen fertilization treatments
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias Agrarias, 2017-05-01)
Nitrogen fertilization has considerable effects on growth and yield of the potato crop. Additionally, leaf expansion is one of the most important growth parameters that can be used to optimize the management of agroecological ...
Can agronomic phosphorus recommendations for potato be environmentally sustainable?
(IPNI, 2017)
A better understanding of the relationship between the agronomic and environmental optimum for soil test P can guide potato growers in Buenos Aires province towards improved P fertilizer management.
Agronomic and Economic Interactions between Sidedressed Nitrogen and Potassium Fertilizations on ‘Atlantic’ Potato
(2020-01-01)
Nitrogen (N) and potassium (K) in potato crop planting synergistically increase tuber yield, but there are no studies on this interaction in sidedressing. In two experiments with ‘Atlantic’ potato combinations of four N ...
Use of a critical phosphorus dilution curve to improve potato crop nutritional management
(Springer, 2016-08)
Plant diagnostic methods to determine P deficiencies need the definition of a critical concentration value which represents the minimum P concentration required to achieve maximum growth. The critical P concentration (Pc) ...
Phosphorus Fertilizer Rate for Fresh Market Potato Cultivars Grown in Tropical Soil with Low Phosphorus Availability
(2016-08-01)
Knowledge on phosphorus (P) response of main potato cultivars is essential to rational fertilization management and maximize yield, mainly in tropical soils that usually have low P availability. An experiment was conducted ...
Reaction to late blight in response to nitrogen management in Argentine potato cultivars
(Elsevier, 2012-12)
The objective of this study was to evaluate the reaction to late blight of two potato cultivars in response to nitrogen (N) management under field and in Vitro conditions. In Balcarce trial a reduction in phenols with the ...
Testing critical phosphorus dilution curves for potato cropped in tropical Oxisols of southeastern Brazil
(2020-04-01)
One of the challenges of potato (Solanum tuberosum L.) production is to minimize phosphorus (P) fertilization without negatively affecting the yield progress. Therefore, critical P dilution curves [Pc = acW−b; where Pc is ...
Partition of biomass and nitrogen in a potato crop under three nitrogen fertilization treatments
(Universidad Central del Ecuador, 2020)
Phosphorus effects on biomass accumulation and nutrient uptake and removal in two potato cultivars
(2016-05-01)
Information on the effect of P fertilization on nutrient uptake and removal by potato (Solanum tuberosum L.) cultivars is required for proper soil nutrient management. This study was performed to evaluate how dry matter ...
