“…These include: (1) in low lying areas of Vietnam, a zero tillage potato production system has been used in rotations after rice harvest, with rice straw used as a mulch in potato fields (FAO, 2012c); (2) in many parts of Asia, rice fields are integrated with aquaculture so that rice plants gain additional nutrients and people gain protein from the fish (FAO, 2004); (3) in China, planting a blast-resistant hybrid rice prevents fungal disease and thereby reduces the fungicide usage and related GHG emissions (IRRI , 2015); (4) some farmers in South Asia have used laserassisted precision land levelling in about 4 Mha of irrigated land, increasing water use efficiency, saving water and increasing productivity by up to 16% compared to the traditional wood-based levelling system (Jat et al, 2009); (5) alternate 10 day wetting and drying (AWD) regimes in rice fields have saved 15e30% of water use without impacting yield (Richards and Ole., 2014), enhancing the root function, microbial activity, and mineral transformations (Bhattarai et al, 2005) and reducing water pumping costs and CH 4 emissions by up to 70% (Lampayan et al, 2015). Given the significant water and GHG benefits, the AWD method is now included in national programmes in Vietnam, Bangladesh, the Philippines and Myanmar (Buresh and Wopereis, 2014); (6) in many parts of Asia, direct seeding is used instead of transplanting as it saves time and water application by up to 33% (Kumar and Ladha, 2011); and (7) recently, substitution of compost manure by urban sewage sludge has been found to be an effective means of emissions mitigation (Fusi et al, 2017).…”

“…La oxifertirrigación pura consiste en la inyección de oxígeno gaseoso a presión en el agua de riego (Bhattarai et al, 2005;Marfa et al, 2005). En la oxifertirrigación física o mecánica se aplica agitación mecánica o inyección de aire directamente en el tanque de solución nutritiva (Castellanos, 2006;Alcayde, 2009).…”

“…Bajo condiciones de hipoxia, la oxifertirrigación asegura un óptimo funcionamiento de la raíz, y mejora la actividad microbiana, las transformaciones minerales y la eficiencia de uso del agua (Bhattarai et al, 2005). Además, compensa los efectos negativos de la compactación y la salinidad sobre la aireación del medio de cultivo, mejorando el crecimiento y el rendimiento de las plantas.…”

El objetivo del presente trabajo fue evaluar el efecto del peróxido de hidrógeno (H2O2) como fuente de oxígeno en la rizosfera, en tomate injertado (cv. Durinta/cv. Maxifor) y utilizando fibra de coco como sustrato. El estudio se llevó a cabo entre los años 2009 y 2010. Se utilizaron dos tratamientos: un control sin H2O2 (T0) y otro con H2O2 (T1) aplicado en cada riego. Se evaluaron parámetros de: i- fertirrigación: oxígeno (O2), pH, conductividad eléctrica (CE) y porcentaje de drenaje; ii- crecimiento: diámetro basal y altura de planta; iii- rendimiento y iv- calidad de fruto: firmeza, grados Brix, peso seco y pH. Durante el ciclo de vida del cultivo, el valor promedio de [O2] en la solución de riego fue 9,92 mg/l en T0 y 12,1 mg/l en T1, mientras que en la solución drenada la [O2] fue de 8,75 mg/l en T0 y de 9,22 mg/l en T1. Aunque se presentaron diferencias significativas (P<0,05) en [O2] entre tratamientos durante algunos periodos del ciclo de cultivo, en el T0 la [O2] no alcanzó un valor crítico que afectara la adecuada oxigenación de las raíces. Por tanto, no hubo efecto del tratamiento con peróxido de hidrógeno (T1) sobre parámetros de fertirrigación, crecimiento, rendimiento y calidad del fruto del cultivo.

“…Several methods have been tested for improving the oxygen supply to crop roots (Bhattarai et al, 2005;Marfà et al, 2005;Urrestarazu and Mazuela, 2005). The supply of pure, pressurized oxygen gas to the nutrient solution is an oxygen-enriched method often used for research purposes (Chun and Takakura, 1994).…”

This work assessed the seasonal dynamics of the substrate oxygen content and the response to oxygen enrichment of nutrient solution (oxyfertigation) of autumn-winter sweet pepper and spring melon crops grown on rockwool slabs (2003/04 season) and perlite grow-bags (2004/05), compared to non-enriched crops. Dissolved Oxygen (DO) values in the nutrient solution were higher for all the oxygen enriched treatments (> 20 mg L -1 ) than for the non-enriched ones (~4 mg L -1 ), but no significant differences were found in the substrate solution. For pepper crops, DO values were highest at the onset and, especially, at the end of the cycle in winter, while the lowest DO values (3 to 4 mg L -1 ) occurred during September and October. For melon, DO values decreased progressively from the onset of the cycles to values ≤ 3 mg L -1 during the second half of the cycles. For pepper crops, there were no significant differences between oxygen treatments for fruit production, which could be attributed to the fact that DO values were > 3 mg L -1 throughout each crop cycle. However, a significant 7% increase in total and marketable yield, associated with a higher fruit number, was observed for the oxygen enriched melon grown on rockwool slabs, whereas no significant differences were found for the melon grown on perlite grow-bags. In conclusion, the use of inexpensive systems of substrate oxygen enrichment should be restricted to rockwool substrates and to crop periods when a high oxygen demand coincides with low oxygen availability, such as the period from melon flowering phase.Additional key words: Capsicum annuum; Cucumis melo; dissolved oxygen; hypoxia; melon; perlite grow-bag; rockwool slab; sweet pepper.
