Fig. 10.—Influence of supplementary P fertilization on heavy N fertilization: all cultures received equal heavy doses of N in form of NaN03; cultures nos. 41 and 104 received equal dosage of extra P; nos. 41 and 44 grown in warm house; nos. 104 and 108 in cool house; P failed to counteract effects of N at higher temperature; chemical analyses made of leaves from this set of cultures. at ioo° C. in an electrically heated oven.
