We used a factorial arrangement A x B, implemented in Design of Random Complete Blocks (D.B.C.A.) in which 24 treatments with 3 replications were analyzed, and two factors under study were evaluated: varieties and fertilization doses. The research is based on determining the influence of temperature and water requirement on the efficiency of nitrogen in two varieties of potato (super chola and supreme) in Salache area, the emergency, of the variety Suprema with the dose D1 Fertilization (200 N - 400 P - 100 K - 60 S) Kg./ha presented the 92.67% emergency. The Superchola variety with the dose D1 Fertilization (200 N - 400 P - 100 K - 60 S) Kg. / Ha with 84.67% being the maximum percentage. The height in the variety Superchola in the dosage D3 = Fertilization (450 N - 400 P - 100 K - 60 S) Kg. / Ha with a height of 98.11cm, while in the variety Supreme in the dosage D1 = Fertilization (200 N - 400 P - 100 K - 60 S) Kg. / Ha with a height of 95,98 cm at 120 days, average height in the two varieties of potatoes. The Superchola variety with the dose D3 Fertilization (450 N - 400 P - 100 K - 60 S) Kg. / Ha with a flowering percentage of 96.33%, the Supreme variety with the D1 dose with a flowering percentage of 97 , 33% being the maximum at 96 days, the variety Superchar in the variable senescence with the dose D2 Fertilization (300 N - 400 P - 100 K - 60 S) Kg. / Ha with 43%, the variety Supreme with the dose D0 = Without fertilization it obtained a 56% of senescence at 155 days.The level of apical nitrogen present in the Superchola Variety with the dose of 450 N - 400 P - 100 K - 60 S Kg. / Ha, presents variability, of 1,83% of Nitrogen in the month of August, 4,52% of Nitrogen in the month of September and 3.59% of Nitrogen in the month of October, the nitrogen of the middle part with a percentage of 4.32% of Nitrogen in the month of September and 3.40 of Nitrogen in the month of October which shows relationship with the temperature of (13.1 ° C) August, (13.6 ° C) September and (14.6 ° C) October and rainfall in August (16.8 mm), September (21 , 1 mm) and October (41.9 mm). The Supreme Variety with a dose of D3 Fertilization 450 N - 400 P - 100 K - 60 S Kg. / Ha, with a percentage of 1,77% of Nitrogen in the month of August, 4,31% of Nitrogen in the month of September and 3.37% of Nitrogen in the month of October, the nitrogen of the middle part is 4.27% of Nitrogen in the month of September, 3.24% of Nitrogen in the month of October, which shows a relationship with the temperature of (13.6 ° C) September and (14.6 ° C) October and the precipitations in September (21.1 mm) and October (41.9 mm). |
