“…At the latter stage, the tomato root activity decreased as the root reached senescence, during which the root activity between the treatments was not significant. Rhizosphere ventilation treatments could significantly enhance root activity [17][18][19][20][21][22][23][24][25][26][27][28][29], increase root absorption capacity [12][13][14][15][16][17][18][19], and promote the growth of aerial parts of tomato. The effects of ventilation treatment in the M soil moisture treatment on root activity were relatively larger, indicating that the appropriate combination of water vapor can effectively promote tomato root growth, thus contributing to promote the tomato plant height, stem diameter, and leaf area growth [19][20][21][22][23][24][25][26][27][28][29].…”

“…According to Li et al [15,16], rhizosphere aeration treatment could promote root metabolism and improve the cucumber root and shoot growth. Furthermore, Bhattarai et al [17] reported that oxygenation could invariably increase season-long water use efficiency (WUE) for fruit and biomass yield and instantaneous leaf transpiration. On the basis of these studies, we used an air compressor in setting different combinations of ventilation volume and soil moisture in order to find a combination that can effectively increase root growth.…”

Soil rhizosphere aeration status is an important aspect of soil quality and soil ecology. The objective of the current study was to determine the appropriate moisture environment that facilitates rhizosphere soil aeration and ensures normal root respiration in tomato. In the potted experiment, five treatments of soil aeration were used (0.4, 0.8, 1.2, 1.6 ventilation volume of 50% porosity of soil, and no ventilation) under conditions of the different soil moisture upper limits. The effects of different rhizosphere soil aerations on the physiological indicators and water absorption of tomato were studied. Under the same soil moisture condition, plant growth and root vitality initially increased, and then decreased when the soil ventilation volume increased. The combination of soil moisture with 80% of field capacity and 0.8 ventilation volume with 50% soil porosity raised the chlorophyll content by 29.98% and the root vitality by 61.55%, as compared with the non-ventilated treatment. Therefore, the appropriate volume of rhizosphere ventilation can effectively improve the capacity of water absorption in tomato. The result provides a new view about soil quality and soil ecology in terms of soil-root system.

“…Aeration through subsurface trickle irrigation tubes stimulated root growth (Bhattarai et al, 2006(Bhattarai et al, , 2008. Studies have indicated that continuous aeration, and aeration after irrigation, performed better than periodic intermittent aeration (Vyrlas and Sakellariou-Makrantonaki, 2005).…”

Sensitivity to low rhizosphere soil aeration may change over time and therefore plant response may also depend on different growth stages of a crop. This study quantified effects of soil aeration during 5 different periods, on growth and yield of trickle-irrigated potted single tomato plants. Irrigation levels were 0.6 to 0.7 (low level) or 0.7 to 0.8 (high level) of total water holding capacity of the pots. Soil was aerated by injecting 2.5 l of air into each pot through the drip tubing immediately after irrigation. Fresh fruit yield, above ground plant dry weight, plant height, and leaf area index response to these treatments were measured. For all these 4 response variables, means of post-infiltration aeration between 58 to 85 days after sowing were 13.4, 43.5, 13.7, and 37.7% higher than those for the non-aerated pots, respectively. The results indicated that: post-infiltration soil aeration can positively impact the yield and growth of sub-surface trickle-irrigated potted tomato plants; positive effects on plant growth can be obtained with aeration during the whole growth period or with aeration for partial periods; positive growth effects of partial periods of aeration appears to persist and result in yield benefit.

“…Options to aerate irrigation water have been developed, and trialled for delivering water to the root zone to alleviate hypoxia, and such system using aerated water for DI and SDI has been referred to as oxygation (Bhattarai et al, 2008). We have measured the occurrence of hypoxia in the root zone of drip-irrigated crops in a range of soil types as it affects the performance in controlled environment experiments (Bhattarai et al, 2004).…”

Lack of oxygen due to sustained wetting fronts associated with drip and subsurface drip irrigated crops in heavy clay soil can negatively impacts on yield, fruit quality and water use efficiency of cucurbit crops. This study evaluated the effects of aerated irrigation water (oxygation) with subsurface drip irrigation, employing an in-line air injector (Mazzei venturi to introduce 12% air by volume of water) on fruit yield, quality and water use efficiency of watermelon (Citrullus vulgaris) and pumpkin (Cucurbita maxima) in a heavy clay soil. The fruit yield with oxygation increased from 14.5 t ha -1 to 24.6 t ha -1 , and 26.3 t ha -1 to 28.9 t ha -1 , for watermelon and pumpkin, respectively. The total soluble solids (TSS) increased by 19% with oxygation (13.2 vs. 11.1%), and internal fruit crack decreased for watermelon, whereas in pumpkin fruit dry matter increased by 4% (40 vs. 38.4%) and TSS by 7% (13.7 vs. 12.8%). Season long water use efficiency was greater with oxygation compared to the control in both crops. The higher yield with oxygation was associated with a more rapid canopy cover, more leaf chlorophyll, and an increase in leaf photosynthetic rate, and leaf transpiration and an increase in fruit number and size. The results suggested that oxygation can ameliorate temporal hypoxia-associated with drip irrigated cucurbit crops in heavy clay soil and also offer yield and fruit quality benefits.
