The experiment was designed to evaluate the effect of sheep manure (SM), its application timing (AT) and N fertilizer (urea) on dry matter partitioning and harvest index. The study was conducted on RCBD split plots arrangement at Agronomic research farm during 2015. Sheep manure (SM1=3 t ha-1, SM2=4 t ha-1, SM3=5 t ha- 1) and application timing (AT1=15 days before sowing, AT2=At sowing time) were allotted to main plots however, fertilizer N (N1=0 kg ha-1, N2= 90 kg ha-1, N3=120 kg ha-1) were applied to sub-plots. Application of 5 t ha-1 of sheep manure at 15 days before sowing significantly enhanced pre-tasseling (stem and leaves) and physiological maturity (stem, leaves, cobs and grains) dry matter partitioning and harvest index. Pre-tassel and physiological maturity dry matter accumulation were higher with application of 120 kg N ha-1 however, Application of 5 t sheep manure ha-1 at 15 days before sowing and 120 kg N ha-1 was recommended for higher dry matter accumulation of maize crop.
