ABSTRACT
Experiments were undertaken to assess the effects of eight days waterlogging on growth parameters of 12 pigeonpea genotypes during kharif of 2011-12 and 2012-13 in Randomized Block Design replicated five times with normal conditions as control. KPBR 80-2-1, ICPB 2039 and ICPH 2431 accumulated the highest dry matter under normal and waterlogged conditions. A pattern of linear increase in LAI exhibited under all conditions. KPBR 80-2-1 attained higher LAI under both the conditions during most of the crop life span. ICPH 2740 and ICPL 20241 showed highest SLA at varying intervals under both the conditions. The RGR indicated higher magnitudes at very early stage of growth i.e. 30-60 DAS followed by reduction in remaining phase. KPBR 80-2-1 and ICPH 2431 had comparatively higher CGR during most of the growth period under both conditions respectively. Significant correlations were shown among the characters investigated under both the conditions. Due to waterlogging the highest reduction was observed in CGR (17.36%) followed by LAI (13.03%), RGR (8.19%), TDM (6.85%) and SLA (4.72%).
