The best storage technique for tuber conservation _ potato consumption was determined in this study. The post-harvest behavior of the potato varieties understudy was evaluated. Finally, a cost report was made for the treatment of the storage systems. A completely randomized block design (DBCA) was applied, for this research, with a factorial arrangement with three repetitions; factor A (ancestral techniques) and factor B (varieties of potatoes). The following indicators were proposed (sprouting, pests, diseases, weight, firmness, Brix degrees, acidity, starch percentage, moisture percentage, dry matter percentage, and color. Infostat statistical analysis was applied. The best ancestral post-harvest storage technique is "yatas," which reaches the first rank in the variables sprouting (77%), firmness (2.68 lb *f /cm2), humidity (79.07%), dry substance (27.43%); in the variable pests and "putza" diseases reaches the first rank with 13%; for the post-harvest behavior, the "super chola" variety reached the first rank of significance in the variables sprouting (64%), pests and diseases (11%), weight (65gr), weight variation ( 10%), firmness (3.04 lb * f / cm2), Brix degrees (5.06 ° Bx) and starch (16.28%). The T1 "yatas" with "super chola" reaches the first rank in the variable sprouting (53%), firmness (3.23 l*f /cm2), Brix degrees (4.93 ° Bx), humidity (78.23%), color (7.5yr 7 / 8) in the epidermis (5 and 7/6) in the endodermis; definitely the T2 ("yatas con chaucha") obtained a lower cost of preparation and storage with a value of $ 106. |
