Greenhouse cucumber cause high yield had high nutritional need, therefore shall pay attention on fertilization
and optimum utilization of chemical and organic fertilizers in this plant. So, present study were carried out in
oerder to investigated interaction between different levels of chemical fertilizer, poultry and dairy manures on
cucumber growth and yield as a factorial experiment in completely randomized design with three factors
including poultry manure in three levels consist of 0, 1 and 1/5 kg/m2, dairy manure in three levels consist of 0,
2 and 4 kg/m2 and chemical fertilizer in three levels consist of 0: 0: 0, 20:33:33 and 40:66:66 g/m2 as urea,
amonium phospate and potasium phosphate, in three replications in greenhouse condition. Various combinations
of chemical fertilizer, dairy and poultry manures had significant effect on bush length, leaf area and yield of this
crop. Application of chemical and organic fertilizers increased yield compared to control. Most yield obtained in
treatment of 4 kg/m2 dairy manure with 1 kg/m2 poultry manure and 20: 33: 33 g/m2 ratio of chemical fertilizer.
Fertilizer combination of 0 kg/m2 dairy manure with 1 kg/m2 poultry manure and 20: 33: 33 g/m2 ratio of
chemical fertilizer had most bush length and fertilizer combination of 4 kg/m2 dairy manure with 0 kg/m2
poultry manure and 20: 33: 33 g/m2 ratio of chemical fertilizer had most leaf area. According to obtained results,
at type and quantity of available fertilizer can use suitable compilation of mineral and organic fertilizers.
