Popis:	Although lowland soils in Asia are frequently fallowed between rice (Oryza saliva L.) crops, little is known about the effects of fallow management on N cycling and growth of a subsequent lowland rice crop. A 2-yr field study was conducted in the Philippines on a Typic Tropaquept to determine the interactive erects of pre-rice land management and urea fertilization on rice growth, N uptake, and response to applied N. Management treatments before transplanting wet-season rice were (i) weedy tallow (WF), (ii) weed-tree tallow (WFF), and (iii) Sesbania rostrata Bremek. & Oberm. grown in situ for either 45 or 60 d as green manure (SR). Weeds and S. rostrata were incorporated after soil flooding on 23 June of each year, and rice was transplanted on 30 June 1989 and 4 July 1990 [...]
