Response of coriander to the mode of phosphorus application.

Three modes of phosphorus application, partly or fully through the soil or foliage, were conducted to evaluate the effect of P application mode on green and fruit yields of coriander and their chemical constituents. The highest values in plant height, green and dry matter production as well as fruit yield, were recorded when P was given partly through soil and foliage. Generally, the three methods of P application increased carbohydrate and protein concentrations in shoots and fruits as compared to the control, in the two seasons in both cuts. The addition of P partly through soil increased the volatile oils concentration of shoots and fruits in the two cuts in both seasons, over the all treatments. The identification of volatile oils in shoots and fruits varied according to the mode of P application.
