Abstract


In the cultivation of cucumber plants is a common problem faced by low soil productivity as Ultisol the fertility rate, as well as unfavorable physical properties. Organic fertilizers like vermicompost can be a solution to improve soil fertility so that growth, cucumber crop production can be increased. The study was conducted from August to December 2015 in the Integrated Field Laboratory, Faculty of Agriculture, University of Lampung. The study used a randomized block design (RAK) factorial 2 x 4. The first factor is the dose of vermicompost 0%, 10%, 20%, 30%, and the second factor, soil depth 0-20 cm (S1) and 20-40 cm (S2), Variance homogeneity test data using Bartlett test, test additivity by Tukey's test. Variance data and differences in the median value of treatment tested with Honestly Significant Difference (HSD) at 5% level. Correlation test to see the relationship between plant growth by pH, organic C, total-N, P-available, uptake of N and P plant at 5% level. The results showed that (1) Application vermicompost at a dose of 30% is best for fruit weight, fruit diameter, the weight of dry stover and pH of the soil, uptake of N and P uptake cucumber plants. (2) The number of female flowers cucumber plants and soil pH is higher at a depth of 0-20 cm compared with a depth of 20-40 cm Ultisol Natar. (3) There is no interaction effect between soil depth is given a dose of vermicompost for growth, the production of cucumber plants, soil pH, uptake of N and P uptake by plants cucumbers.
