Effects of Applying Nitrogen on Yield of Silage Maize Grown after Forage Legumes
Abstract
In a 2-year study, it was determined how winter planting
various forage legumes (Hungarian vetch, narbon vetch and forage pea) before
applying nitrogen (0, 5, 10, 15 and 20 kg N da-1) affected the yield
components of silage maize grown afterward. Fallow was applied for control
treatment. The results showed that among the forage legumes cultivated from
October to May, forage peas afforded the highest fresh weight (4279 kg da-1)
and the dry matter ratio (20.50%). However, narbon vetch affected all other
yield components of silage maize except dry matter ratio more positively than
the other legumes and increased the green yield by 30.3% compared yields
achieved in control plots. The dry matter ratio of silage maize was higher in
plots grown with Hungarian vetch and forage pea plots because of their later sowing
and harvest times. Later, applying nitrogen positively affected the green
yields of silage maize by up to 15 kg N da-1. Such results readily
apply to cultivating crops with high nitrogen demands (e.g., maize) in soils
with low organic matter content. It was concluded that narbon vetch as a
previous crop should be advised for silage maize and top-dressing of 15 kg N da-1
could be beneficial for increasing green maize
yield.
