EFFECT OF PHOSPHORUS AND BIO FERTILISERS ON LEGHAE- MOGLOBIN AND NITROGEN FIXATION OF CHICKPEA

Abstract

The effect of different levels of phosphorus and biofertilisers on the leghaemoglobin and nitrogen fixation of chickpea was studied under field conditions at the Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, during 1978-79 and 1979-80 rabi seasons. Fresh weight of nodules increased significantly with increasing levels of phosphorus as well as with Rhizobium inoculation. Rhizobium inoculation had marked influence on leghaemoglobin content of nodule tissue. The total leghaemoglobin content in the nodules is directly related to the total nitrogen fixed by the chickpea.
