ABSTRACT
The aim of this work was to evaluate mixed cropping triticale with legumes using different cattle manure levels for optimum forage productivity in a split plot arrangement having 3 main plots and 4 sub-plots with three replicates. Triticale was cultivated as monocrop, mixed cropped with hairy vetch and winter pea under 3 main plots. Four manure levels were also evaluated under 4 sub-plots: 0 kg N (nitrogen)/ha (control), 50, 100 & 150 kg N/ha. The collected data were analyzed using general linear model procedure through Statistical Analysis Software (SAS). Dry matter (DM) yield of triticale-vetch mixed crop was higher (P<0.05) at 150 kg N/ha level than that of control and not different (P>0.05) from that of 50 and 100 kg N/ha. The DM yield of triticale-pea was not different (P>0.05) from that of control and triticale-vetch mixed crop at all manure levels. Crude protein (CP) yield of triticale hairy vetch and pea mixtures was not different (P>0.05) across all manure levels. Yield of total digestible nutrients (TDN) was highest at 150 kg N/ha in triticale sole monocrop, followed by 100, 50 and 0 kg N/ha levels. The overall TDN yield in triticale vetch mixture with 100 kg N/ha was higher (P<0.05) than control and not different (P>0.05) from 50 and 150 kg N/ha levels. However, TDN yield of triticale-pea mixture was greater (P<0.05) than triticale monocrop. Carrying capacity for Hanwoo cows in triticale with vetch and pea were also not different (P>0.05) from triticale-vetch mixed crop at all nitrogen levels. Mixed cropping produced optimum CP yield and carrying capacity for Hanwoo cows even without manure application, whereas 50 kg N/ha manure could be needed for optimal DM and TDN yield. It was concluded that optimum forage productivity could be achieved by application of 50 kg N/ha from animal manure and mixed sowing of triticale with hairy vetch or winter pea.
