The results showed: By giving different liquid slurry bio fertilizerdoses gave a significant effect on the leaf area of cucumber plants at the age of 21 HSTobservations. The best treatment for organic fertilizer dosage is in the treatment of 120 L ha -1(P3). The application of spacing has a significant effect on the stem diameter variable at the ageof 28 HST observations, and on leaf area variables at all ages of observation. The best treatmentof spacing on the variable stem diameter and leaf area on the treatment spacing of 60x60 cm(J4). There were no significant interactions on the treatment of liquid bio slurry fertilizer dosesand the spacing of growth and yield of cucumber plants at all ages of observation.
