Investigations on studies on organic farming in maize- sunflower- greengram cropping system were carried out for two consecutive years (2003-04 and 2004-2005) at S.V. Agricultural College Farm (ANGRAU), Tirupati (Southern Agro-Climatic Zone of Andhra Pradesh). In these investigations, maize was grown during late kharif season during both the years. Various quality parameters of maize were influenced differently by varied manurial practices tried. However, during both the years of investigation, the trend was largely similar between the two years, with respect to all the parameters. Grain quality parameters (protein content, starch content and amino acid content) of maize were at their best with recommended dose of fertilizer either with or without panchagavya spray. However, all the above mentioned parameters were significantly higher with the application of farm yard manure or pig manure or vermicompost in combination with foliar application of panchagavya than with any other organic manurial practices tried.
