POTENSI SERAPAN NITROGEN OLEH GULMA DAN JAGUNG MANIS (Zea mays var. saccharata sturt) PADA SISTEM TOT

Abstrak

The objective the study was to know N uptake potential by weed and sweet corn at no-tillage system. Design used in the experiment was CRD (Completely Randomized Design) with 4 X 3 factorial pattern replicated three trials. Two factors treated were nitrogen fertilizer dosage of four levels, those are (0, 100, 200, 300 kg Urea ha^-1) and no-tillage system. The result indicated that there were dominated weeds, shifting from Digitaria Cilliaris to Synedrella nodiflora (L) Gaertn. And  Cyperus rotundus L. N uptake potential by weeds was higher than sweet corn at no-tillage system
