“…Similarly, Krauss and Marschner (1984) observed cessation of starch accumulation when developing tubers were subjected to soil temperature of 30°C. It could also be possible that allocation of assimilated carbon into nonstructural and structural carbon was altered by the high soil temperature (Arai-Sanoh et al 2010).…”

Integrating crop species with different photosynthetic pathways has great potential to increase efficiency in the use of scarce resources. In order to tap the resource complementarity emanating from this mix, this study intercropped potato (Solanum tuberosum L.) with lima bean (Phaseolus lunatas L.) and dolichos (Lablab purpureous L.), and related soil temperature with radiation use efficiency and crop water productivity of rainfed potato in the upper midland (1552 m above sea level (masl), lowerhighland (1854 masl) and upper-highland (2553 masl)) agro-ecological zones of Kenya. Leaf area index (LAI), light interception, soil temperature and soil water contents (SWC) were quantified at different stages of potato growth and related with the radiation use efficiency (RUE) and crop water productivity (CWP) of potato. Intercropping increased crop LAI by 26-57% relative to sole potato stands and significantly lowered the soil temperatures in the 0-30 cm depth by up to 7.3°C. This caused an increase in SWC by up to 38%, thus increasing RUE by 56-78% and CWP by 45-67%. Intercropping potato with legumes is coupled with optimum root-zone soil temperature and soil water content, thus potentially exerting additive relations in radiation interception and subsequent conversion into crop biomass. ResumenLa integración de especies de cultivos con diferentes rutas fotosintéticas tiene un gran potencial para aumentar la eficiencia en el uso de escasos recursos. A fin de aprovechar la complementariedad de la fuente surgida de esta mezcla, en este estudio se intercaló la papa (Solanum tuberosum L.) con el frijol lima (Phaseolus lunatus L.) y frijol de Egipto (Lablab purpureous L.), y se relacionó con temperatura del suelo, con el uso de la eficiencia radioactiva y la productividad del agua del cultivo de la papa de secano en área de altura media (1552 metros sobre el nivel del mar, masl), tierra elevada baja (1854 masl) y tierra elevada alta (2553 masl) en la zona agroecológica de Kenia. Se cuantificó el índice de área foliar (LAI), la intercepción de la luz, la temperatura del suelo y su contenido de agua (SWC), a diferentes etapas del crecimiento de la papa y se relacionó con el uso eficiente de la radiación (RUE) y la productividad del agua del cultivo de la papa (CWP). Los cultivos mezclados aumentaron el LAI en 26-27% en relación al cultivo de la papa sola y bajó significativamente las temperaturas del suelo en los 0-30 cm de profundidad hasta 7.3°C. Esto causó un incremento en SWC por hasta 38%, incrementando, por ende, la RUE en 56-78% y la CWP en 45-67%. Intercalando papas con leguminosas se acopla con la temperatura óptima de la zona radical del suelo y el contenido de agua, ejerciendo, en consecuencia, potencialidad en las relaciones aditivas en la intercepción de la radiación y la subsecuente conversión hacia la biomasa del cultivo.

“…Direct climate change-induced abiotic stressors such as increased temperature and rising atmospheric CO 2 clearly affect plant physiology and thus rice yields (Arai-Sanoh et al 2010;Lin et al 2010;Myers et al 2014;Welch et al 2010;Ziska et al 1996), but the indirect effects of climate change are less well understood. These indirect or secondary effects include more release and uptake of toxic metal(loid)s such as As due to higher transpirational water flux, microbial activity, and elemental cycling in paddy fields (Guo et al 2011) if dry seasons get drier, and increased susceptibility to infection by devastating fungal pathogens such as Magnaporthe oryzae (Kobayashi et al 2006), causal agent of rice blast if wet seasons get wetter.…”

Biogeochemical impacts of silicon-rich rice residue incorporation into flooded soils: Implications for rice nutrition and cycling of arsenic

Aim Soil incorporation of Si-rich rice residues may aid smallholder rice farmers in improving crop yields and may affect As uptake. Here, the biogeochemical impacts of rice residue incorporation into flooded soil without plants were evaluated. Methods Various particle sizes of fresh rice straw (FS), fresh rice husk (FH), rice straw ash (RSA) and rice husk ash (RHA) residues were incorporated into soil (1 % w/w) in a flooded pot experiment. Pore-water chemistry was monitored weekly and dissolved CH 4 concentrations and genes specific for methanotrophy and methanogenesis in DNA extracts of soil were evaluated. Results FH-amended soil had the highest level of dissolved Si, followed by FS and then ash (RHA or RSA). Particle size had little effect on the dissolved Si concentration for any residue tested. No amendments had any substantial effect on pore-water pH. FS-amended soil had much higher As, Fe, and CH 4 concentrations in pore-water compared to ash and FH, and its extracted DNA also had higher amplifications of genes indicative of methanogenesis. Conclusion FH, RHA, or RSA are attractive amendments for smallholder rice farmers to increase plantavailable Si without exacerbating CH 4 emissions, which may improve rice nutrition through the beneficial impacts of Si on combating biotic and abiotic stress including decreased arsenic uptake.

“…Interestingly, significantly more biomass was allocated to the shoot than to the root of birch seedlings at 23°C compared with 18°C indicating that either control of PAC was more costly at 23°C or the rate of nutrient acquisition per unit root biomass was higher at 23°C, and consequently, at higher temperature, a small root system was as efficient as a large one at lower temperature. Also Xu and Huang (2000) and Arai‐Sanoh and colleagues (2010) could observe a decreasing root/shoot ratio with increasing temperature for Agrostis palustris and Oryza sativa , respectively.…”

Interactions of Betula pendula and Picea abies with dark septate endophytes of the Phialocephala fortinii-Acephala applanata species complex (PAC) were studied. PAC are ubiquitous fungal root symbionts of many woody plant species but their ecological role is largely unknown. Sterile birch and spruce seedlings in monoculture and mixed culture were exposed to four PAC strains, added either singularly or paired in all possible combinations at 18°C and 23°C. Plant and fungal biomass was determined after 4 months. The most significant factors were strain and host combination. One of the strains significantly reduced biomass gain of spruce but not of birch. Plant biomass was negatively correlated with total endophytic fungal biomass in half of the strain - plant combinations. Endophytic PAC biomass was four times higher in spruce (≈ 40 mg g(-1) drw) than in birch (≈ 10 mg g(-1) drw). Competition between strains was strain-dependent with some strains significantly reducing colonization density of other strains, and, thus, attenuating adverse effects of 'pathogenic' strains on plant growth in some strain - plant combinations. Biomass gain of spruce but not of birch was significantly reduced at higher temperature. In conclusion, host, fungal genotype, colonization density and presence of a competing PAC strain were the main determining factors for plant growth.
