Abstract
Field experiments were conducted during winter (August February) seasons of 2003-04 and 2004-05 under irrigated condition at Coimbatore to study the usefulness of bio-inoculants in reducing the inorganic nitrogen and phosphatic fertilizers for cotton. Four graded levels of N and P ( 0,50,75 and 100 % recommended dose (RDNP) and four bio inoculants viz ., Azospir illum from, Haryana, Tamil Nadu and Surat were combined with Phosphorus Solubilizing Bacteria (PSB) + Pink Pigmented Facultative Methylotrophs (PPFM) along with uninoculated control. Cotton LRA 5166 responded significantly to graded levels of N and P and bio-inoculants. Application of 75% RDNP along with Azospirillum (HAU) + PSB + PPFM yielded 2.91 tonne/ha seed cotton with higher net return (Rs 40,553) and net B:C ratio value of 1.94 while, application of 100% RDNP without bio-inoculants yielded only 2.54 tonne/ha. Judicious combination of bio-inoculants along with moderate use of chemical fertilizers is recommended for cotton.
