Impact of different sources of nutrition and Plant Growth Promoting Rhizobacteria (PGPR) on growth and yield of cucumber (Cucumis sativus L.) Under naturally ventilated polyhouse

Abstract

An experiment was conducted during Late kharif 2025 at College of Agriculture, KSNUAHS, Shivamogga, to study the impact of different sources of nutrition and plant growth promoting rhizobacteria (PGPR) on growth and yield of cucumber under naturally ventilated polyhouse conditions. The experiment was laid out in Randomized Completely Block Design (RCBD) design by using KPCH-1 (F1 Hybrid) with eleven treatments and replicated thrice. The results revealed that application of 80% RDN + 20% through Vermicompost on N equivalent basis + PGPR consortia (T9) was recorded significantly higher growth parameters like maximum vine length (361.67 cm), vine girth (12.13 mm), number of nodes per vine (19.28), number of leaves per vine (37.73), internodal length (12.25 cm) and total number of branches per vine (11.97). Whereas, yield related traits such as like fruit length (15.35 cm), fruit width (4.33 cm), fruit weight (191.67 grams), number of fruits per vine (9.65), yield per vine (1.85 kg), yield per plot (36.96 kg), yield per 1000 m2 (30.47 q) and yield per hectare (304.73 q) are also recorded as higher in T9 treatment under polyhouse condition.
