ABSTRACT
A field experiment was conducted at Instructional Farm, Rajasthan College of Agriculture, Udaipur during rabi season in 2013-14 and 2014-15 to study the efficacy of organic, inorganic and biofertilizers on yield and nutrient uptake by wheat (Triticum aestivum L.) in Haplustepts. The results revealed that grain yield (5.04 t ha-1), straw yield (9.69 t ha-1) and biological yield (14.73 t ha-1) significantly increased with the application of poultry manure @ 5 t ha-1 over other organic manures. Further results showed that the application of 75 per cent RDF significantly increased the grain yield (4.84 t ha-1) straw yield (9.24 t ha-1) and biological yield (14.07 t ha-1) over 50 per cent RDF and statistically at par with 100 per cent RDF and inoculations of seed with Azotobacter + PSB significantly increased the grain yield (5.01 t ha-1), straw yield (9.65 t ha-1) and biological yield (14.67 t ha-1) over single inoculation. However 5 t ha-1 poultry manure , 75 per cent RDF and Azotobacter + PSB significantly increase the N (1.538 & 0.535 %), (130.23 kg ha-1), (1.519 & 0.530 %), (123.02 kg ha-1), (1.547 & 0.537), (129.98 kg ha-1), P (0.355 & 0.224 %), (39.93 kg ha-1), (0.345 & 0.216 %), (37.05 kg ha-1), (0.358 & 0.221), (39.68 kg ha-1) and K (0.548 & 1.482 %), (171.69 kg ha-1), (0.539 & 1.462 %), (162.06 kg ha-1), (0.543 & 1.479), (170.55 kg ha-1) content and uptake respectively in wheat crop. So the results revealed that application of poultry manure @ 5 t ha-1, 75 per cent RDF and dual inoculation of biofertilzers gave higher yield of wheat there by a saving of 25% of nutrients.
