A field experiment was conducted to study the response of microbes and bioregulators on yield growth and productivity of chickpea (Cicer arietinum L.) under rainfed condition during 2010-11 and 2011-2012 on sandy loam soils with factorial randomized block design consisting of four levels of biofertilizers inoculation viz., no inoculation, phosphate solubilizing bacteria (PSB), vesicular arbuscular mycorrhizae (VAM) and PSB+VAM with two bio-regulators viz., homo-brassinolide @ 1 ppm and gibberelic acid @ 1000 ppm at pre-flowering and pod-filling stage. Result showed that the yield attributes like number of grains plant-1and test weight were highest in treatment

receiving homo-brassinolide and dual inoculation of PSB+VAM. Grain yield was highest (2139 and 2211 kg ha-1) in treatment receiving PS+VAM application over no inoculation (957 and 1072 kg ha-1). The grain yield was highest (1705 and 1797 kg ha-1) in treatment receiving homo-brassnolide and lowest grain yield (1481 and 1569 kg ha-1) at gibberelic acid during 2010-11 and 2011-12, respectively.
