GREEN MANURING FOR RICE WITH RHIZOBIUM INOCULATED Sesbania grandiflora

Abstract

                                The Rhizobium isolates were obtained from root nodules of Sesbania grandiflora (L.) grown in different soil samples. In Leonard jar experiment, the plants inoculated with the isolate. SG-5 gave maximum dry weight (1 g/plant), nodule number (47 per pl int) and total nitrogen content (51.80 mg/plant). Similarly pot culture experiment also revealed that plant inoculated with SG-5 isolate gave maximum dry weight (1.51 g/plant) and total nitrogen content (43.34 mg/plant). The response of rice crop to the incorporation of inoculated green manure was encouraging with respect to nitrogen content, phosphorus content and grain yield.

Key words : Rice, Green Manuring, Rhizobium, Sesbania grandiflora
