Abstract: A field experiment was conducted during the rabi 2015-16 at Instructional Farm, Department of Agronomy, College of Agriculture, Junagadh Agricultural University, Junagadh to study the ‘‘Response of Indian mustard (Brassica juncea L.) to different levels of organic manures and bio-fertilizers’’. The experiment was comprised of sixteen treatment combinations in which four levels of organic manure viz., no organic manure, FYM @ 5.0 t/ha, vermicompost @ 1.0 t/ha & castor cake @ 1.0 t/ha and four levels of bio-fertilizer viz., no inoculation, inoculation with Azotobacter spp. @ 10 ml/kg seed, inoculation with PSB spp. @ 10 ml/kg seed & inoculation with Azotobacter spp. + PSB spp. (each @ 10 ml/kg seed). The experiment results revealed that application of FYM @ 5.0 t/ha enhanced growth parameters viz., plant height, number of primary & secondary branches per plant; yield attributes viz., number of siliquae per plant and number of seed per siliqua and ultimately higher seed and stover yield with higher net returns of 82037 Rs/ha and B: C ratio 2.97 over control (no organic manures). Seed inoculation with azotobacter spp. + PSB spp. (each @ 10 ml/kg seed) promoted growth parameters viz., number of primary & secondary branches per plant; yield attributes viz., number of siliquae per plant and number of seed per siliqua and ultimately higher seed and stover yield with higher net returns of 86629 Rs/ha and B: C ratio 3.40 over control (no inoculation).
