Abstract

A two year field experiment was conducted at Patancheru, AP., India during season 2009 and 2010 in Alfisols to study the direct and interaction effects of row ratio (4:1 and 3:1), row spacing (75 cm and 150 cm), plant-to-plant spacing (30 cm and 50 cm) and irrigation (every 14 and 18 days interval during flower initiation till pod development) on the growth and yield of ICPA2043. The total effects of irrigation and row ratios and its interactions including the interaction of row ratio, plant spacing and irrigation was found not significant on the total seed yield (kg/ha) of ICPA 2043. However, the direct effect of the different plant spacings did influenced the agronomic and yield traits of parental linedue to variations in plant population. The study further suggests that 75 cm x 30 cmis the optimum plant spacing coupled with the adoption of either of the two row ratios and irrigation frequencies will produced ample amount of seeds of parent line materials of hybrid pigeonpea.
