 ABSTRACT

Water logging is one of the environmental stresses that affect the growth, physiology and yield attributes injured due to the anaerobic environment. The objective of above investigation was to study the variation in Growth, physiological   and yield characteristics in soybean genotypes/varieties. The genotypes were grown under excess moisture condition and recommended cultivation (control). The experiment was carried out   at the research of Plant Breeding & Genetics, RAK College of Agriculture, Sehore (M.P.) during 2014 seasons. A total of 25 soybean genotypes/varieties were grown in complete randomized block design with three replications having 5 rows 40cm apart with 3meter row length of every genotype. Water logging was created at 20 DAS, 40 DAS and 60 DAS in event of no rains after planting by applying water level about 5 cm above the soil surface. The mean   data of the all characters viz.  plant height, number of branches/plant,  number of nodules/plant , dry  weight of nodules/plant, ascent of sap  in (%), transpiration rate in (mmol H2O mˉ ² s-1),harvest index (%) and yield (q/ha.) were computed for statistical analysis as per the standard procedure given by (Panse & Sukhatme 1989). The results revealed that soybean could grow and produce grains even under water logging condition. The significant differences were observed among the genotypes for major growth physiological and yield attributes except number of branches, number of nodules and ascent of sap in the year. Further the result revealed that high magnitude of characters like plant height, dry weight of nodules, transpiration rate harvest index and yield per hectare were found in genotypes/varieties RVS2007-7, JS2069, RVS2007-1, RVS2001-4 and JS 2059 in the year as compare to control. Hence these genotypes/varieties were found suitable under waterlogged condition.
