Abstract

This experiment aims to evaluate the effects of vermicompost produced from sheep manure on growth, yield and quality of 2 fruit cucumber (Cucumis sativus L.) varieties (cv. ‘Sultan F1’ and cv. ‘Storm F1’)
under greenhouse condition. Four vermicompost treatments at the rate of 0 (control), 10, 20 and 30 t ha-1 were incorporated into the top 15 cm of soil. During the experiment, fruits were harvested three times
per week and fruit number and weight were recorded for 3 months. Leaf number, plant height and chlorophyll content were measured at 30, 60 and 90 days after transplanting, while leaf area, stem and leaf dry weight and fruit qualitative properties were evaluated at 90 days after transplanting. The results showed that leaf number, plant height and chlorophyll content increased significantly (P 0.05) compared to control plots for both varieties at 30, 60 and 90 days after transplanting. The plots treated
with 30 t ha-1 vermicompost showed increase in leaf are, stem and leaf dry weight for both varieties. The application of vermicompost at 30 t ha-1 increased total fruit yield 26% for cv. ‘Sultan F1’ and 25% for cv.
‘Storm F1’ compared to the control. The plots treated with vermicompost at 30 t ha-1 enhanced fruit number per plant 26% for cv. ‘Sultan F1’ and 25% for cv. ‘Storm F1’ than plot without vermicompost. Fruit harvested from plants receiving vermicompost had higher total soluble solid (TSS), lower juice acidity and more dry matter than plots without vermicompost. Growth and yield parameters were improved with increasing vermicompost rates up to 20 t ha-1. There are no significant different between plots at 20 and 30 t ha-1 vermicompost in all evaluated parameters.
