| Abstract Field experiment was were conducted in Afak AL-Qadissaya Governorate at autumn season of 2010 to study the effect of concentration of (LIQ HUMUS) humus liquid fertilizer on some quality parameters of two potato cultivators. The experiment included 8 interaction treatments which were the result of two potato cultivars ( Aladin and Burren ) and four concentrations of Liquid humus fertilizer (0,50,75 and 100 ml/L) that donated as b0 , b1, b2 , b3. Spraying was done three times during the growing season with an interval of 14 days. The results showed significant supremacy of Burren cultivar for, the percentage of Nitrogen, phosphorus and potassium, and vitamin C in tubers. Aladin cv. Was significantly super in the percentage of dry matter, starch, nitrate in tubers compared to.Spraying results for all liquid humus concentrations were significant on the percentage of nitrogen, phosphorus and potassium, vitamin C, percentage of dry matter and starch in tubers, for both locations. (100 ml/L) conc. gave the highest means for the above studied parameters compared with control treatments that gave the lowest means for the same parameters. Meanwhile, b0 conc. was significantly super in Nitrate in tubers compared to b3 conc. Interactions treatments between two the parameter showed significant effect. The Interaction treatment (100 m/l × Burren cv ) produced the highest means for the aforementioned parameters; (Total yield, percentage of (N, P and K) and vitamin C) in tubers which gave (27.40, 1.25, 0.414 ,1.98 and 24.89) in comparison to the control treatment, which gave (10.83, 0.77, 0.165, 1.05 and 20.16 ) respectively. While the treatment a1b3 gave the highest means for the aforementioned parameters; dry matter percentage, starch, Nitrate in tubers showing the values (19.90 و13.734 ) in comparison to a2b0 treatment, which gave (16.60, 10.790) respectively. While the a1b0 treatment gave the highest mean for the aforementioned parameter, nitrate quality in tubers. It gave the value of (0.283 ) in comparison to a2b3 treatment, which gave the lowest mean (0.153 ). | ||
