Effects of waterlogging on microbial activity, soil nutrient availability, nutrient uptake, and yield of tolerant and sensitive onion genotypes.

ABSTRACT:

Introduction

Rainfall variability during the monsoon season poses a major challenge to onion production, especially due to waterlogging stress in clay loam soils. Saturated conditions reduce soil aeration, disrupt microbial activity and nutrient transformations, and impair nutrient uptake and crop performance.

Methods

To investigate these effects, a field experiment was conducted under a split-plot design with flatbed layout to assess changes in soil physical properties, microbial activity, nutrient availability, and their combined effects on nutrient uptake and bulb yield in eight onion genotypes (two tolerant and six sensitive).

Results and discussion

Waterlogging increased bulk density by 5.30% and reduced infiltration rate by 76.5% compared to control. At 50 days
