If people irrigate the crops with waste water, will that influence the rate of growth of the plants?
All depends on the kind of plant and waste water you are dealing with. The presence of heavy metals could be poisonous to the plants. The presence of NaNO3 or KNO3 or NH4NO3 may enhance plant growth. Phosphates may enhance growth and formation of wheat- ear.
The question is whether the waste water contains those nutrients required by the crop plants to grow, flourish, and produce or not.
@ Sudip Saha: As mentioned above, the most important is if wastewater composition (presence of nitrogen, phosphorus, potassium and other chemicals, which can be utilized by plants for growth) is feasible for plant growth enhancement.

Along with the nutrient composition , the microbial community in the wastewater also needs consideration. Wastewater microbes may affect the soil bacteria and will compete for the available resources.
Also it may also be a potential hazard if there are any pathogenic microbes and the plants will come in contact with humans.
The best solution would be disinfection of wastewater before use.
i think that the kind of wastewater is a vital rule in this field due to level of toxicity, such as the composition of olive mill wastewater is a variable and complex including polyphenols and tannis which are not easily degradable .
It depends upon the suitability of that water to the growth of the plants.
Some factors can affect the composition and growth of microbial biomass (bacteria, fungi and yeasts) in biological wastewater treatment system including: wastewater characteristics (nutrient contents, pH, temperature, dissolved oxygen, etc.) and operational parameters (solids retention time (SRT), returned activated sludge (RAS), food to microorganisms (F/M) ratio, mixing system, plant configuration, etc.).
pH, dissolved oxygen (DO), nutrients content, organic matter and temperature are the most important parameters
I do agree with Dr Omar Al-Khashman. The pH, DO, temperature and OM content of wastewater are essential components.
TO ANSWER ABOUT THIS QUESSTION FIT, WHAT TYPE OF WASTEWATER YOU NEED?
It depends upon the suitability of waste water to the growth of the plants and the quality of water it depend on major parameters such as; salinity, TSS, pH, DO, nutrients contents, metals and organic materials
Wastewater contains various types of contaminants which generally affect the growth. There are some common lab procedures to determine such effects.
However, wastewater must be treated before using it.
Wastewater is the by product of any water that has been affected by human use. It is used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff or rain water, and any sewer inflow or sewer infiltration . Soil and environment are under tremendous pressure due to industrial expansion and discharge of effluents. Unlike healthy irrigation water, Wastewater has an adverse effect on the life history of plant growth.
domestic w/w & municipal w/w these two are fitted to plant growth faster . It
contents inorganic , organic, & biodegradable matter which accelerate photosynthesis process in plants. First one was practically proved by Hon. Late
karmaveer Bhaurao Patil in Dhananichi Bhag in SATARA last 25 yrs ago. same
solution be a long term answer if everyone does it in own Prasbag. Latter one need some simple treatment I agree , but having moderate cost/ 1000 lit.
pH and temperature of the waste water is very important for the growth of the plants.
It is important to determine what kind of wastewater are you talking about. When you employ wastewater containing waste stream from kitchen, the content of surfactant and other cleaning and washing agents could br toxic for plants. It is onla an example. So you have carefully evaluate a quality of wastewater to be used for plant watering and then make a decission.

Thanks!
It depends on what type of waste water. Municibal waste water has alot of hazard factors and definitly will affect negativelly plant growth. However, treating it may remove these detterorating factors. On the other hand, industrial waste water is the worst to affect plant growth specially because of heave and toxic metal contents. Agricultural waste water is the best to reuse because usually it needs just to be mixed with fresh water to reduce its EC.
Thanks Sir Professor A. M.R. Abdel-Mawgoud for your invaluable remarks.
I agree with you agricultural waste water can be reused. But in this case I think we should be careful about pesticides.
Of course, due to contents high levels of toxic metals such as (Pb, As, Hg,Cd Cu.....)
