Abstract

The mini cucumber (Cucumis sativus L.) variety was characterised by a crunchy texture and low seed content, making it well-suited for lowland cultivation. Mini cucumbers typically produce short, capsule-shaped fruits. This study investigated the effects of plant growth-promoting rhizobacteria (PGPR) dosage and different pruning strategies on the growth and yield of mini hybrid cucumbers. The experiment was arranged in a factorial randomised complete block design (RCBD) with 2 factors. The first factor consisted of four PGPR dosages derived from bamboo roots, namely 0, 20, 40 and 60 mL L-1. The second factor comprised four pruning treatments: no pruning, main stem pruning, pruning of three lateral branches and pruning of five lateral branches. The results demonstrated that both PGPR application and pruning significantly affected vegetative and generative growth parameters of mini hybrid cucumbers. Application of PGPR at 60 mL L-1 significantly increased plant height by 26.11 %, leaf number by 30.00 % and fruit weight per plant by 44.04 % compared to the control. Meanwhile, pruning of three lateral branches significantly increased plant height by 24.90 %, fruit diameter by 13.22 %, fruit length by 28.50 % and total fruit yield per hectare by 47.36 % relative to the control. These findings indicate that appropriate PGPR application combined with strategic pruning practices can substantially enhance the growth and productivity of mini hybrid cucumbers.
