Var. Desiree(Class-A). The tubers were sprouted, theinfected and mechanically damage tuber were discarded . The tuber seeds wereplanted using spacing of 4.5 *1.6 m. The field experiment included eighttreatments as follows:-1- Haulm distractions by hands and stopping irrigation ,22 days before harvest.2- Haulm distractions by hands before 22 days and stopping irrigation 11days before harvest.3- Haulm distractions by hands before 22 days and stopping irrigation 6days before harvest.2013 ، 53 الحمداني و آخرون - 38 : ( 1 ) مجلة ديالى للعلوم الزراعية ، 5534- Haulm killing by gramoxone and stopping irrigation 22 days beforeharvest.5- Haulm killing by gramoxone before 22 days and stopping irrigation 11days before harvest.6- Haulm killing by gramoxone before 22 days and stopping irrigation 6days before harvest.7- Haulm killing by Basta before 17 days and stopping irrigation 6 daysbefore harvest.8-The plants left without distractions and stopping irrigation 6 daysbefore harvest. In this experiments the qualitative characters of thetuber yield were studied . Two groups of 5 kg tubers were taken fromeach replicates and bagged in bags . The first group were kept in coldstore at 4 ± 1 ◦c and 85 ±5 % relative humidity with out curing.The second groups were cured at 10-15 ◦c and relative humidity of80-85 % for 15 days then transported parts to cool store for three months andthe tubers were reconditionized at 31- 35 ◦c and relative humidity of 46-53 %for 10 days. The experiment included 16 treatments distributed in factorialexperimental in three replicates using R.C.B.D. and the means of thetreatments were compared using L.S.D. at level of significance of 5%.The experiment results showed that :-The haulm killing with gramixone , and stopping irrigation 22days before harvest significantly increased the corke cell layer while thehaulm killing with basta before 17 days and stopping irrigation ,6 daysbefore harvest increased the percentage of cured tubers anddecreased the percentage of sprouting and the percentage of weight loss.All the haulm killing by hand treatments before 22 days and stoppingirrigation before 22, 11 , 6 days from harvesting significantly reduced thepercentage of microbial infection to zero level. Haulm killing with gramixonebefore 22 days and Stopping irrigation 11 days before harvest increased thepercentage of protein , while haulm destruction by hand before 22 days andstopping irrigation 11days before harvest significantly increased thepercentage of vitamin C . The curing of potato tubers significantly increasedvitamin C content while the non cured tuber significantly showed a highercork cell layer thickness and lowest percentage of sprouting and weight loss .No significant differences between the cured and non cured tubers in thepercentage of cured tubers , microbial infection and protein content.
