Assessment Of Yield and Yield Components Of Maize-Hybrids Under High Plant Population Density in the Northern Guinea savanna of Nigeria

A field experiment was conducted during 2015 and 2016 rainy season at Tudun Wada, Kano and Samaru, Zaria in the Northern Guinea Savanna of Nigeria in order to assess the yield and yield components of maize-hybrids at high plant population. The experiment consisted of two plant populations of 53,333 plantha-1 and 88,888 plantsha-1 as main plot and 8 drought–tolerant maize-hybrids (M0826-7, M0926-8, M1026-10, M1026-13, M1124-4, M1124-10, M1227-12 and M1227-14) and 2 controls (Oba-98 and Oba super-1) as sub-plot laid out in a randomized split-plot design and replicated three times. Based on these results, increasing plant population significantly increased the yield and yield components of maize-hybrids. However recent hybrids were more tolerant to high plant population than the older hybrids. Therefore the recently released hybrids were more adapted to biotic stresses.
