ABSTRACT
A pot culture experiment was conducted at Department of Crop physiology, S.V. Agricultural College,Tirupati during kharif 2013 to know the effect of waterlogging on certain biochemical and yield parameters of Redgram (Cajanus cajan (L.) Millsp).The experiment was conducted in a spilt pot design with different time periods of waterlogging as main treatments and genotypes as subplots. LRG 30, Maruti and Asha were the genotypes tested. Waterlogging affected all the biochemical and yield parameters viz., reducing and total reducing sugars, superoxide dismutase, membrane stability index, number of pods per plant, pod dry weight and seed yield. The three different periods of stress imposition were 40 DAS (vegetative stage), 80 DAS (reproductive stage) and 120 DAS (pod formation stage). Sensitive stage of crop to watelogging was recorded. Water logging at 40DAS affected super oxide dismutase, reducing sugars and total sugars. When stress was imposed at 80DAS only pod dry weight affected. A greater decrease in number of pods per plant and seed yield was observed when stress was imposed at 120 DAS. The present study forms a biochemical basis to understand the sensitive stage of redgram to waterlogging stress.
Key words: Redgram, Waterlogging, Biochemical, Yeld parameters.
