QUALITY PARAMETERS OF MAIZE AS INFLUENCED BY APPLICATION OF FERTILIZERS AND MANURES

Abstract

An investigation to study the biochemical changes in maize under continuous application of fertilizers and manures was undertaken with ten treatments at Tamil Nadu Agricultural University, Coimbatore. The NPK + FYM treatment resulted in producing maize grain of better quality. The non-addition of any fertilizer, elimination of S and K significantly reduced the grain quality. No appreciable variation could be observed with different levels of NPK in the quality constituents such as starches, protein, carbohydrates, sugars and phenols.

Keywords: NPK + FYM, Starch, Protein, Carbohydrates, Sugars, Phenols
