Response of Two Maize Hybrids Productivity to Inter-and Intra-Rows Spacing

Abstract

Two field experiments were carried out during two summer seasons (2017 and 2018) at the Experimental Farm of the Faculty of Agriculture, Assiut University, Assiut, to study the response of two maize hybrids [Single Cross 128 (S.C. 128) and Triple Cross 310 (T.C. 310)] yield and its components for three interrows spacing (Rw 1 = 60 cm, Rw 2 = 70 cm and Rw 3 = 80 cm) and three intra-rows spacing (S 1 = 20 cm, S 2 = 25 cm and S 3 = 30 cm). Experimental design was randomized complete block design (RCBD) using split-plot in strips, where interrow spacing allocated in the main horizontally, maize hybrids were arranged in the main vertically and intra-row spacing were occupied the sub-plots. According to results, the maximum values of plant height and ear diameter in both seasons, ear length in the 1 st season, ear grains weight and grain yield/fed.
