Two field experiments were carried out during two summer seasons 2018 and 2019 at the Experimental Farm of the Faculty of Agriculture, Assiut University, Assiut, to study the response of two maize hybrids [Single Cross (S.C.) 10 (H1) and Trible Cross (T.C.) 321 (H2)] on yield and its components of three irrigation
intervals (I1= 11 day, I2= 16 day and I3= 21 day) and three foliar proline application (P0= control (water only), P1= 100 ppm and P2= 200 ppm. Experimental design was randomized complete block design (RCBD) using split-plot in strips, where irrigation intervals allocated in the main vertically, proline were arranged
in the main horizontally and maize hybrids were occupied the sub-plots.
According to research results, the maximum values for plant height, yield components and grain yield/fed. were obtained by the irrigated plants at 11 day interval in both seasons.
- The highest values of plant height, ear grains weight and 100 grain weight in both seasons; as well as grain yield/fed. in the 1st season were recorded by control, while grain yield/fed. as well as ear length and ear diameter in the 2nd season were realized by 100 and 200 ppm proline, respectively.
- The hybrid S.C. 10 grave the highest values for plant height and ear length in both seasons, as well as ear grains weight and grain yield/fed. in the 1st season, while hybrid T.C. 321 surpassed for traits of ear diameter and 100 grain weight in both seasons.
- The first order interaction H1xI1 (S.C. 10 x 11 day interval) achieved the maximum values for plant height and grains yield/fed. (21.1 and 22.5 ard.) in both seasons, while H2xI1 interaction (T.C. 321 x 11 day interval) achieved the maximum values for ear diameter in both seasons and 100 grain weight in the
1st season only.
- The interaction H1xP1 (S.C. 10 x 100 ppm proline) and H2xP2 (T.C. 321 x 200 ppm proline) gave the maximum grain yield/fed. (19.5 ard.) and ear diameter in the 2nd season only, respectively.
- The interaction P1xI1 (100 ppm proline x 11 day interval) and P2xI1 (200 ppm proline x 11 day interval) showed the maximum grain yield/fed. (22.5 ard.)
and ear diameter in the 2nd season only, respectively.
- The second order interaction H1xP0xI1 (S.C. 10 x control x 11 day interval) and H2xP2xI1 (T.C. 321 x 200 ppm proline x 11 day interval) in both seasons gave the highest values for plant height and ear diameter, respectively, moreover, H1xP1xI1 interaction (S.C. 10 x 100 ppm x 11 day interval) gave the maximum
one for grain yield/fed. (23.9 ard.) in the 2nd season only.
