The effect of swimmer crab flour (Protunus pelagicus) and Arbuscular Mycorrhizal Fungi on flowering and yield of Japanese Cucumber (Cucumis sativus L.)

Abstract

Abstract Swimmer crab flour (Protunus pelagicus) which has high Ca content and Arbuscular Mycorrhizal Fungi (AMF) can be used to overcome acid soil. The aim of this research was to know the interaction effect of swimmer crab flour and AMF on increasing acidic dry soil productivity for the growth and yield of Japanese cucumber plant. The polybag research was conducted at Nagreg Subdistrict, West Jawa, Indonesia from May to July 2018 using Randomized Block Design with two factors and three repilactions. The first factor was swimmer crab flour doses (control, r1 = 9 g 5 Kg soil−1, 12 g 5 kg soil−1,15 g 5 kg soil−1 and 18g 5 Kg soil−1) and the second factor was AMF dosage (control, 5 g crop−1 and 10 g crop−1). The results showed that there was an interaction effect of swimmer crab flour and AMF on the root infection degree, there was main effect of swimmer crab flour on flowering time, dry weight of fruits, and harvest index of cucumber, and there was an main effect of AMF on the harvest index. Thus the application of swimmer crab flour more reliable to increase japanese cucumber production.
