Two corn hybrids i.e. Pioneer 3062 and Pioneer 3012 were tested with farmyard and poultry manure along with urea in a field
experiment carried out on a sandy clay loam soil. The two hybrids differed significantly in number of cobs per plant, 1000-grain weight and grain yield. On the other hand, harvest index remained unaffected by treatments. Hybrid pioneer 3062
performed better with respect to all parameters, except number of grains per cob. Combined use of poultry manure and urea
performed the best amongst all treatments.
