I have determined the shoot dry weight yield per pot, P concentration, P uptake and available P in soil. I am now looking for the approach of calculating P use efficiency by wheat grown in pot experiment.
do you have data on applied p.
you can calculate physiological p use efficiency which is most appropriate for pot provided you have maintained uniform number of plants per pot across treatments.
you can calculate agronomic p use efficiency which for pot culture will be little far from reality but you can compare treatment differences if you have kept same soil mix in all pots, and maintained uniformity in soil weight pot size watering schedules and plant number per pot across treatments.
do you have soil available p data before planting and after harvest.
Thanks Bhupinder Singh for your reply. We have only dry shoot weight not grain yield.soil available P was calculated only after sowing. What is the best way to get PUE? For physiological PUE what is the Formula?
Regards
Physiological efficiency is the best way to express nutrient use efficiency. Its need data of nutrient uptake in treated and control pot. its formula is given below
Physiological use efficiency = [P uptake in treated pot (g/pot) - P uptake in control pot (g/pot)]/ P applied (g/pot)
