Yield and physiological attributes of soybean as influenced by P mobilizers under varying irrigation regimes

Abstract

A field experiment was carried out during Summer 1994 and 1995 at Vamban, Pudukkottai to study the yield and physiological attributes of soybean (Glycine max (L) Marrill) as influenced by P management using P mobilizers under varying irrigation regimes. Irrespective of season, irrigation at IW/CPE ratio of 0.8 were significantly increased the various growth analysis parameters viz. DMP. LAI, LAD, CGR and NAR of soybean. The grain yield was increased by irrigation at IW/CPE ratio of 0.8 in both the experiments. An appreciable increase in physiological attributes and grain yield were recorded at 80 kg P,O, ha').

Keywords: Soybean, Physiological attributes. Yield. P management. "P" mobilizers, Irrigation
