Abstract


Field experiments were conducted for two consecutiveKharif seasons of 2003 and 2004 at S.V. Agricultural college farm (ANGRAU), Tirupati , Southern plateau and Hills zone of India on red sandy soils with fourteen treatments comprising of six different sources of nitrogen viz., farm yard manure, vermicompost, neem leaf, poultry manure, pig manure and fertilizer to supply recommended dose of nitrogen on equal nitrogen basis and one absolute control. All the seven treatments were tried with and without the foliar application of Panchagavya, thus, making the total treatments to fourteen. Various 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. All the growth and yield attributes, yield (grain as well as stover) harvest index, nitrogen uptake and the grain quality parameters (protein content, starch content and amino acid content) and gross returns as well as net returns of maize were at their best with recommended dose of fertilizer either with or without Panchagavya spray. However, among different organic manures 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. Foliar application ofPanchagavya could not exert any pronounced effect in combination with recommended dose of fertilizer, while combination of foliar application of Panchagavya would be fruitful only with certain organic manures only
