The present study was aimed to determine the efficiency of different combinations of seed inoculation with micronutrients [Ammonium Molybdate: (NH4)6Mo7O24) and cobalt sulphate: CoSO4] on chickpea plant height, nodule count and seed yield. The experiment was carried out for three consecutive winter seasons from 2010 - 2011 to 2012 - 2013 in Gujarat State of India. The inoculation treatments influenced significantly the chickpea plant height, nodules/plant and therefore, the seed yield. Application of recommended dose of fertilizers (RDF) + ammonium molybdate (2.0 g/kg seed) + Rhizobium (Mesorhizobium ciceri) + phosphate solubilizing bacteria (PSB species Bacillus subtilis) recorded significantly highest chickpea plant height (40.9 cm) and nodules/plant (26.5) and remained equivalent with application of RDF + ammonium molybdate (2.0 g /kg seed) + CoSO4 (2.0 g /kg seed) + Rhizobium + PSB. In contrast, RDF without inoculation (control) had the lowest chickpea plant height (37.4 cm) and nodules/plant (21.0). Significantly, the highest chickpea seed yield (1882 kg/ha) was produced with combination of RDF + ammonium molybdate (1.0 g/kg seed) + Rhizobium + PSB over control (1538 kg/ha) and remained equal with RDF + ammonium molybdate (2.0 g/kg seed) + Rhizobium + PSB (1832 kg/ha) and RDF + Rhizobium + PSB (1805 kg/ha) and produced 22.4, 19.1, and 17.4% more seed yield over control, respectively.
