The potato (Solanum tuberosum) is the fourth most important crop in the world, after wheat, rice and corn, and is a staple food for a large part of the population, being rightly considered the second bread of mankind. Along with its nutritional importance and culinary use, the potato is also appreciated as a raw material in the food and bakery industry, but also for its therapeutic effects. By using varieties with different vegetation periods, consumption is ensured throughout the year. The experiments aiming at the organic fertilization of the potato culture took place in Cralovăț locality, Timis county. The potato crop was sown by hand, in bundles, and the treatments against pests were of ecological type, the potato fertilization being done with manure, sheep manure and complex mineral fertilizers. The highest yields of 26.6 t / ha of potatoes were determined by applying 20 t / ha of manure. Among the fertilization variants applied, for which the best quality indicators were determined, the manure variant in a dose of 20 t / ha was noted, the manure being a complex fertilizer that ensures the balanced nutrition of the potato. The cumulative effect of organic fertilizers applied in the first year of experience and mineral fertilizers applied in the second year resulted in higher and higher yields.
