Abstract

Lodging is a common phenomenon in rice cultivation. Occurrence of lodging reduces yield. Factors associated with lodging include varietal characteristics, rate of nitrogen fertiliser applied and season. Results indicated that varieties MR 84 and MR 101 were more tolerant to lodging than MR 81 and MR 71. Varietal characteristic associated with susceptibility to lodging was plant height. Increasing the nitrogen rates (up to 160 kg/ha) increased lodging susceptibility (3–38%). Occurrence of lodging was found to be more severe in the off-season. Interaction of variety, nitrogen and season effect on lodging is also discussed. Based on the results, recommendations to overcome the lodging problem and thus increase yield are suggested.
