This treatment showed lower concentrations of Cd2+ and NO3 – than the control, increasing yield quality and maintaining the same yield quantity.
Results showed that increasing humic substances application rates up to 120 kg ha−1 enhanced tubers yield quantity, starch content and total soluble solids.
Subsurface drip irrigation system was found to be more efficient than surface drip irrigation system on improving tubers yield quantity, quality parameters and nutrients concentration content, in addition to soil fertility after harvesting.
Results showed a clear positively enhancement of plant vegetative growth parameters, chlorophyll, N, P, and K contents of leaves and seed yield quantity and quality positively by sowing large seeds compared with other seed sizes.
The aim of this study was to evaluate the effect of humic substances application in sandy soil under surface and subsurface drip irrigation systems on potato tubers yield quantity, quality, nutrients concentration in tubers and soil fertility after harvesting.
The paper also shows that the current relative definitions of ductility, as a ratio between an ultimate deformation/displacement and the corresponding yield quantity, should be replaced by absolute definitions of ductility, for example the ultimate deformation/displacement, as the latter ones better represent the ductile structural behavior.
In addition to yield quantity, yield quality is also an important parameter.
However, development of calibration curves or the use of internal standards can reveal important quantitative information, including oil content, conversion yield, quantity of biodiesel produced, and more.
At the time of this study, the SimplyRNA HT system was at the end of beta testing, and future refinements to the kit may increase yield quantity, quality and precision.
