Effect of Cattle Slurry on Growth, Biomass Yield and Chemical Composition of Maize Fodder

초록

An experiment was carried out to study the effect of cattle slurry on maize fodder (Zea mays) production. Maize fodder was produced at 4 cattle slurry levels T-0 (0 ton/ha), T-1 (10 ton/ha), T-2 (12 ton/ha) and T-3 (14 ton/ha) in a randomized block design. Agronomic characteristics, plant heights, circumference of stems, number of leaves, leaf area and dry matter yield of maize fodder were measured. Maize plant height and stem circumference were significantly (p<0.01) influenced by the increasing rate of cattle slurry at 15, 30, 45 and 56 days after sowing. Number of leaves of fodder plants was not significant but leaf area was significant (p<0.05) among the treatment groups. The highest biomass yield (p<0.01) of maize fodder was observed in T-2 (44.0 ton/ha). For crude protein content, a significant difference (p<0.01) was observed in the treatment groups and the highest value was observed in T-2 (11.99%). Organic matter content of maize fodder showed a significant difference but ash, ADF and NDF contents showed no significant differences among treatment groups. From this study it may be concluded that the application of 12 tons of cattle slurry/ha was optimal for production of biomass and nutrient content of maize fodder.
