LAJU SERAPAN NITROGEN TANAMAN PADI DAN GULMA Fimbristylis miliacea PADA PEMBERIAN PUPUK NITROGEN DAN GENANGAN AIR
Abstract
Information about the effect of combination of
nitrogen dosages and amount of water flooding on
nitrogen upake rate and wetland rice growth and
weed Fimbristylis miliacea (L.) Vahl which
growth around of it, is important to know. Polybag
experiments was conducted on green house of East
Java Research Institute of Agricultural
Technology. Result showed that on 15 cm
flooding and 0.90 g nitrogen per polybag gave a
better nitrogen uptake, N tissue content, chlorophyl
content, better rice growth, and the lowest growth
of weed Fimbristylis miliacea.
