Abstract
The research was conducted in a farm and in a refrigerated warehouses in the private sector in the governorate of Diyala , In order to study the effect of seed size and spraying with two types of foliar fertilizers, on phenotypic and marketing characteristics of potato tubers Lola variety stored for three months . Used three sizes of tubers, small tubers average weight of 50 g, medium-sized tubers average weight of 75 g and large tubers average weight of 100 g. And planted in the autumn loop at the end of August 2011. The plants sprayed in the field with two kinds of leafy fertilizers Ferity green and Grow more twice, after 28 days of tubers germination , and the second after 21 days from the first spray. The conducted sorting was done after harvesting and had excluded infected tubers, distorted and unfit for marketing, then mobilized those tubers with nylon bags clamp weighing 5 kg for each experimental unit , and those bags were distributed on three replications and stored at temperature 4 + 1 for three months . Used complete randomized block design CRBD, and after the expiration of the storage conducted the statistical data collection process. Results showed superiority significant differences in the percentage of the lost in tubers weight and in percentage of total damage , Where medium-sized tubers outperformed compared with small and large , during periods of storage (30, 60 and 90 days) . Spray with foliar fertilizers achieved a significant superiority of nutritious Grow more, compared with Ferity green in these tow traits . Interaction between tuber size during periods of storage, was in favor of medium-sized tubers sprayed with Grow more foliar fertilizer. Had achieved significant superiority over all other interventions . In the percentage of germinated sprouts, Large tubers was achieved significantly on both medium and small , while medium tubers was excelled than small tubers . For the spraying with foliar fertilizers, Ferity green relatively achieved superiority than Grow more fertilizer, but this superiority was not significant . Interference between the average weight of the tubers and the type of foliar fertilizers, showed significant superiority of large tubers sprayed with Ferity green .
