The subject "influence of varieties, nitrogen, phosphate, potassium wages to productivity growth, cucumber (Cucumis sativus l.) on grey soils in the Country" have been made in the city of Pleiku, Gia Lai province from November 2014 to 2015, in order to determine the amount of cucumber, like nitrogen, phosphorus and potassium are suitable for growing cucumber trees reach productivity and economic efficiency best for farmers planting cucumber in Pleiku, Gia Lai province. The subject of two experiments the two elements are arranged according to the type of extra batch, repeated three times. The first experiments to determine the amount of fertilizer and seed and suitable to the growth and yield of cucumber with the main plot (A) are the three just like cucumber (NH 815 (d/c); TN 327; TN 172); extra batches (B) are the four levels of phosphate (70; 95 (d/c) 145 120 kg P2O5/ha;. The second experiment in order to determine the appropriate amount of nitrogen and potassium to the growth and yield of cucumber with the main plot (A) four levels of potassium fertilizer (115; 155 (d/c); the 184 235 kg K2O/ha;); extra batches (B) are the four levels of nitrogen (110; 150 (d/c); 190; 230 kgN/ha).The results showed in laboratory experiments determine appropriate fertilizer and seed for the growth and yield of cucumber, on the 500 kg/ha of lime fertilizers 15 tons/ha animal manure + + 150 kg N/ha + 155 kg/ha K2O growing cucumber plants grow good for productivity (39.86 tons/ha), profit (126,644,890) and earnings (1.57) reached the highest results when planted NH815và 145 kg P2O5/ha. For the experiments determined the amount of potassium and nitrogen fertilizer to growth and yield of cucumber tree, the results showed on the 500 kg/ha of lime fertilizers 15 tons/ha animal manure + the + 95 kg P2O5/ha cucumber tree growth and good development for highest productivity (47.77 tons/ha) , profits are 180,436,155/ha and the earnings gain is 2.38 when manure K2O 190 kg and 195 kg ends N/ha.
