Influence of the supply and uptake of nitrogen on the quality of potato tubersere four replications in all experiments and all were irrigated. Harvests were taken at 10, 8, 5, and 5 intervals during the growing seasons of the four years, respectively, when full sets of growth analysis measurements were made, including , , and the partitioning of N within the plants bet

Organic manures and mineral fertilizersic manures are bulky, expensive to transport and contain small amounts of nutrients per unit volume. In addition, the amount and rate of release of nutrients from organic manures is often difficult to predict with accuracy, especially for nitrogen. Some of the benefits and concerns about the use of organic manures are discussed in this paper.
