Grain Yield and Yield Components of Quality Protein Maize Genotypes as Influenced by Irrigation and Plant Population in the Nigerian Savannah

Abstract

An experiment was conducted to assess the yield and yield components of QPM genotypes to plant population under irrigated conditions in a semi arid ecology of Northern Nigeria. Field trials were conducted at the Irrigation Research Station, Institute for Agricultural Research, Kadawa (11° 39′N, 08° 20′E) and 500 m above sea level) during dry seasons 2007, 2008 and 2009 to study the effect of (Zea mays L.) genotypes (TZE-W Pop X 1368, EV-DT W99 STR and DMR-ESRW), four plant population (33333, 44444, 55555 and 66666 plants ha -1 ) and three irrigation scheduling (40, 60 and 80 centibars soil moisture tension) on the growth and yield of quality protein maize. A split plot design was used with combinations of genotypes and irrigation regimes assigned to the main plot and plant population assigned to the sub-plot. The treatments were replicated three times. The study revealed that genotype EV-DT W99 STR had significantly higher weight of ears per plant, cob length, cob diameter, number of rows per cob, 100 grain weight, grain yield, shelling percentage and harvest index than the other two genotypes used in the trial. Irrigating at 40 and 60 centibars significantly increased weight of ears per plant, while delayed irrigation significantly depressed total dry matter production. Based on the results obtained in this study, it can be concluded that the use of genotype EV-DT W99 STR, at 60 centibars irrigation scheduling and population of 55,555 plants ha -1 had resulted in good agro-physiological characters of QPM at Kadawa.

Weed Persistence, Crop Resistance and Phytotonic Effects of Herbicides in Maize (Zea mays) Production Under Different Weed Control Method and Poultry Manure in Kano State Nigeria

“…The varietal differences were only significant in 2016 at Dangora in which SAMMAZ 21 and SAMMAZ 35 statistically recording higher grain yield compared with the SAMMAZ 15. Similar findings were reported by Sani et al (2015) that, varieties of maize differ in their potential productivity. The ability of SAMMAZ 21 and 35 to efficiently smother and intercept more solar radiation might have led to its higher production of grain yield.…”

Effect of Municipal Solid Wastes On Grain Yield of Three Maize Cultivars

“…According to Ma et al (1999), Younas et al (2002), and Nasim et al (2012, who noted that genetic potentials had a major impact on yield and yield components of maize, the varietal differences in yield have a similar approach. Similar to this, other studies have documented differences in growth and yield among various maize varieties and genotypes (Hamidu, 1999;Bello, 2001;Ogunbode et al, 2001;Mani, 2004;Abdulai et al, 2007;Abdelmula and Sabie, 2007;Sharifi and Taghizadeh, 2009;Badu-Apraku andFontem-Lum, 2010 andSani et al, 2013). The variance in yield seen between the various maize cultivars may be due to environmental conditions.…”

Nitrogen Source and Rate Management Improve Maize Productivity of Smallholders under Semiarid Climates

“…Hokmalipour et al (2010) reported significant variation in N use efficiency, productivity and growers income among various maize cultivars. Many other workers (e.g., Akram et al, 2010; Sampath et al, 2013; Hejazi and Soleymani, 2014; Sani et al, 2014) reported variations in yield and yield components among different maize cultivars. Cui et al (2009) reported that the interaction between genotypes and nitrogen significantly influence grain yield and NUE in maize.…”
