3.3.2. Accumulation of nitrogen (N), phosphorus (P) and potas-

sium (K) as influenced by proline accumulation in maize leaves

Data depicted in Table (3) and Fig. (2) conspicuously dis-
played changes of (N, P, K) concentrations as affected by sprayed

proline for T0, T1, T2 and T3 treatments. Proline accumulation per-
centage values for T0, T1, T2 and T3 were 12, 16, 14 and 13 %,

respectively.

The corresponded percentages of (N, P, K) concoctions were
0.30, 0.18, 0.18 % with control treatment (T0), whereas (N, P, K)

concentrations associated with T1 were 0.86, 0.52 and 0.84 %, re-
spectively. On the other hand, (N, P, K) percentages were 0.77, 0.36

and 0.74 % with T2, while concentrations of (N, P, K) with T3 treat-
ment were 0.34, 0.29 and 0.51, respectively. Fig. (3) obviously re-

vealed that increment of (N, P, and K) was directly proportional to
proline accumulated under all treatments applied.
