Effects of urea nitrogen and residual composted municipal waste and sheep manure on the growth and chemical composition of two triticale genotypes

ABSTRACT

In 2012, a greenhouse experiment was conducted to investigate the effects of field soil (C0), residual composted municipal waste (CMW), and residual composted sheep manure (SM) on the growth of triticale in pots previously growing oilseed rape in 2011. To each soil group, one of three levels of urea nitrogen (N) fertilizer was added. Results demonstrated that triticale grown in pots previously containing oilseed rape plants containing SM or CMW with 150 kg urea N ha⁻¹ had the highest N content. Plants grown in SM with 150 kg N ha⁻¹ had the greatest seed yield, but yield was not significantly different from plants grown in CMW receiving 150 kg N ha⁻¹. Triticale plants enriched by either SM or CMW had a higher amount of N, copper, zinc, and manganese compared to the field soil control.
