“…4) with the increase in the position in the toposequence was 20% (Fig. 4), which was similar to those reported in actual rainfed rice areas in Asian monsoon regions (Homma et al, 2003;Samson et al, 2004;Boling et al, 2008). Our results showed smaller reduction in shoot dry matter production against the increase in position in the toposequence than in the study using a similar sloping experimental setup but with more severe drought stress (Fujii, 1993), and showed significant genotypic differences in the vertical root system distribution against the increase in the position in the toposequence (Fig.…”

“…In such a case, IRAT109 exhibited better performance than KDML105 because it was able to match its root plasticity to soil moisture, which is more available in the deeper soil layer. This pattern of root plasticity exhibited by IRAT109 may be one of the possible reasons why some rice genotypes maintained their yield potential even when planted at higher toposequential positions with limited soil moisture supply in the upper soil layer (Tsubo et al, 2006;Boling et al, 2008).…”

“…Entre os segmentos de vertente, verificou-se que nas áreas de topo (alto e baixo) os teores são mais elevadosresultados atribuídos às melhores condições de drenagem, acumulação de matéria orgânica, ciclagem de nutrientes (Boling et al, 2008), além de menor incidência de erosão. Quanto aos teores de P disponível, observou-se que no topo alto os valores são mais baixos que nas áreas de encosta, sopé de transporte e topo baixo.…”

“…Top positions are more likely to have water stress problems while the low position to flood problems, and the fertilizer application may accompany more risks. While Boling et al (2008) did not find the toposequence position effect on fertilizer responsiveness in Ubon Ratchathani, Northeast Thailand, this may be related to their inconsistent effect of toposequence position on chemical and physical characteristics.…”

“…In the Mekong region, it is widely recognized that there can be large variations in grain yield among rainfed lowland rice (Oryza sativa L.) fields within relatively small areas, this variability reflecting a combination of differences in water availability, soil fertility and fertilizer inputs (Anbumozhi et al, 1998;Wade et al, 1999;Homma et al, 2003;Inthapanya et al, 2000;Tsubo et al, 2006Tsubo et al, , 2007Boling et al, 2008). Ouk et al (2006) reported significant variability in water availability around flowering time in the rainfed lowland environment, with water stress often being associated with reduced yield.…”
