SUMMARY

A field experiment was conducted atduring, IGKV, Raipur, Chhattisgarh rabi, 2011-12 to study the effect of tillage practices and nutrient management on growth, fodder yield and quality of oat (Avena sativa L.). The treatments comprised zero tillage, minimal tillage and conventioanal tillage I main plots and 75 % RDF, 75% RDF + Bio-fertilizers, 100% RDF, 100% RDF + Bio-fertilizers in sub plots. The experiment conducted showed that highest green and dry fodde yields were recorded in the plots treated with conventioanl tillage.Highest net returns and B:C ratio was ecorded under plots treated with conventioanl tillage. In case of nutrient management highest green fodder and dry foder yields and net returns and B:C ratio was recorded in the plots treated with 100% RDF + Bio-fertilizers (Azotobacter and PSB).

key words: tillage practices, nutrient management, oat,  fodder yield and  quality
