SUMMARY
The experiment on effect of primary biomethanated spentwash on physico-chemical properties of sodic vertisols and yield of fodder maize was carried at Post Graduate Farm, MPKV, Rahuri during 2011-12. The effect of varying doses of primary biomethanated spentwash (100, 200, 300, 400 and 500 m3/ha) and combination of FYM+RDF, FYM+50% GR and FYM+RDF+100 per cent GR+RDF on soil properties, nutrient uptake, growth and yield of fodder maize was studied. The experimental soil was Vertic Haplustepts with alkaline (pH 8.90), calcareous (CaCO3 10.50%), clay in texture, high in exchangeable sodium (10.60 cmol (p+)/kg) and ESP (25.20) with low in available nitrogen and phosphorus and high in available potassium. The available N, P and K after harvest of fodder maize crop were significantly higher in PBSW treatment applied @ 500 m3/ha, however, uptake and yield of fodder maize were significantly higher in 400 and 500 m3/ha treatments (495.30 and 517.31 q/ha green yield, respectively) followed by FYM+RDF+ 50 per cent GR and FYM+RDF+100 per cent GR.
