Application of Paclobutrazol and Electrical Conductivity value of nutrient solutions to improve yield and quality Cucumis sativus L var Japanese on the hydroponic system

Many factors influence the yield and quality of hydroponically cultivated Japanese cucumber plants. This study aims to study the interaction of Paclobutrazol and the Electrical Conductivity (EC) of nutrient solution to improve the yield and quality of cucumbers. The study was conducted in February 2019-April 2019 at the greenhouse of Universitas Padjadjaran, Jatinangor. The research method used was a split-plot design consisting of two factors and three replications. The first factor is the value of EC n1 = (2.0-3.2 mS cm−1), n2 = (2.0-3.4 mS cm−1) and n3 = (2.0-3.6 mS cm−1) ) and the second factor is Paclobutrazol concentration p1 = 0 ml l−1, p2 = 0.375 ml l−1 and 0.75 ml l−1. The parameters of growth and yield of plants observed were leaf area, day of flowering, number of male flowers, number of female flowers, number of fruits, fruit weight, and percentage of normal fruit shape. The observational data were then analyzed by the variance analysis of 5% significance level and continued with Duncan's test at 5% level. The results showed there was no interaction of Paclobutrazol factors and EC of nutrient solution values. Plant growth without the application of Paclobutrazol and EC generative stage 3.2 mS cm−1 yields better crop quality and yield.
