Irrigated wheat, vermicompost, FYM, Azotobacter & PSB, grain yield.


An experiment was conducted during two consecutive winter seasons (rabi) of 2011-12 and 2012-13 to assess the response of superimposed nutritional levels consisted vermicompost @ 5t/ha, FYM @ 10 t/ha, seed inoculation with Azotobacter and PSB, individually and in combination over recommended dose of fertilizers in wheat crop under irrigated condition. The response of fertility levels was analysed on growth characters, yield attributes and yield as well as economic parameters of normal sown wheat variety PBW-502. Seven superimposed fertility levels compared with only recommended dose of fertilizer treatment (control) laid out in Randomized Block Design replicated three times. The soil of field was sandy loam in texture, deficient in nitrogen, medium in phosphorus and potash. The integration of vermicompost, FYM, Azotobacter & PSBalong with inorganic fertilizers dose in different treatments exhibited significant response in terms of increasing grain yield of wheat from 12.66 to 18.36 per cent and 16.21 to 27.90 per cent compared to control treatment which recorded lowest 46.29 and 41.33 q/ha grain yield during 2011-12 and 2012-13, respectively. Treatment-8 (RDF + vermicompost 5.0 t/ha + Azotobacter and PSBas seed treatment and spraying at Ist and IInd irrigation) recorded maximum grain yield (56.70 and 57.33 q/ha), straw yield (72.92 and 88.67 q/ha), gross income (Rs. 87443.50 and Rs. 97127.50/ha) and net income (Rs. 37001 and Rs. 45462) during 2011-12 and 2012-13, respectively.
