ANALYSIS OF GROWTH AND DEVELOPMENT OF MAIZE IN RESPONSE TO INTEGRATION OF POULTRY MANURE WITH CHEMICAL FERTILIZERS IN MAIZE (Zea mays L.)

The experiments were carried out in experimental farm at faculty of agriculture, Annamalai University during 2015, with an objective to explore the response of maize to incorporation of graded dose of poultry manure and chemical fertilizers. Twenty different treatments with two replications each were carried out in the plot in RBD design. The percent increase in grain yield ranged from (41.5 to 100.8) and stover yield ranged from (21.8 to 41.6) due to poultry manure alone. The percent increase in the grain yield ranged from (24.4 to 81.7) and Stover yield ranged from (10.7 to 35.6) due to fertilizer alone and percent increase in grain yield ranged from (51.5 to 235.5) and stover yield ranged from (16.6 to 78.9) due to poultry manure and fertilizers. The highest grain yield 6214.3 kg ha-1 and stover yield 8454 kg ha-1 was noticed with poultry manure @6 t ha-1 + 100 % NPK.
