Abstract:
The present experiment was conducted at Horticultural Research Farm, SKN College of Agriculture, Jobner, Rajasthan during 2017. The experiment was conducted in a randomized block design with sixteen treatments replicated thrice. The treatments include different organic manures (control, FYM @ 20 t ha^-1, vermicompost @ 6 t ha^-1 and poultry manure @ 8 t ha^-1) with biofertilizers (control, Azospirillum, PSB and Azospirillum+ PSB). The results showed that application of FYM @ 20 t ha^-1 recorded the maximum values of soil organic carbon (2.5 mg g^-1), available nitrogen (127.49 kg ha^-1); dehydrogenase (15.86 μg TPF/g soil/hr) and alkaline phosphate activity (11.85 μg PNP/g soil/hr) and microbial population (actinomycetes, fungi and bacteria). Among different biofertilizers Azospirillum+ PSB resulted significantly increased all soil parameters (soil organic carbon, available N, P and K content, enzymatic activities and microbial population.
