Four soil water content lest thresholds (relative to the percentage of field water capacity) for starting the irrigation (45%-I45, 55%-I55, 65%-I65, 75%-I75) were compared inside plastic greenhouse experiment in 2009. Amount of applied irrigation water for four treatments varied from 120.1 ...
Percentage of the surface and maximum wetted radius to wetted depth under dripper were increased. Also, the percentage of the soil surface wetted radius for all treatments compared to continuous flow without soil conditioner was increased. Predicted and observed values were compare...
Although the effect of irrigation strategies was statistically significant on weight of fruit in a previous study (Parvizi et al., 2014), the aril and peel percentage and juice density for different irrigation strategies were the same and non-significant in this study (Table 5). For Rabab cult...
摘要: Investigates the effect of subsurface drip irrigation and fertigation of broccoli in Arizona. Percentage of acceptable yields and net return of maximum predicted response within the treatments; Accumulation of NO[sub 3] solution in the top of the soil; Boundaries of overlap areas....
Walk into the irrigation department of a big box home improvement store in most parts of the country, and you will probably see hundreds of drip/low-volume products displayed. But be careful, a high percentage of those products should only be installed in residential situations. In order to ...
2,Control the valve position by percentage 3,Irrigation water capacity setting, to control water consumption 4,Malfunction warning,water shortage warning(work with flow meter),low power warning etc,to provide secure user experience 5,When it start watering, the real-time...
9a). We then calculated the percentage of RPF weight at each 5 cm interval to the total RPF weight at each cotton field, i.e., the relative amount of RPF along the soil profile (Fig. 9b). We found that except for the field with 5-year of mulching practice (indicated by the ...
Nitrogen apparent recovery fraction (Nrf) is an index to express the percentage of nitrogen fertilizer recovery in plants30. In this study, there were no significant differences in Nrf among F1, F2 and F3. In the view of N rate, F3 (0.16 g N per kg soil) had the potential for ...
A two-year field experiment was conducted to examine the effects of biochar addition, irrigation level and water salinity on soil N2O emissions, maize yield and grain N uptake in Northwest China. Eight treatments in total included the combination of two biochar addition rates of 0 t/ha (B0) ...
