CORRELATIONS AMONG GRAIN YIELD AND YIELD ATTRIBUTES IN MAIZE VARIETIES AS INFLUENCED BY TIMING NITROGEN SECOND DOSE APPLICATION

Ladan K Muhammad, Hassan A Hamidu

Abstract


Three maize varieties (SAMMAZ 14, SAMMAZ 15 and SAMMAZ 16) were compared for yield and yield components and correlation were worked out among the yield parameters against timing of second dose application of nitrogen fertilizer at 4, 5, 6, 7, 8 and 9 weeks after sowing (WAS) conducted at Institute for Agricultural Research Farm (Lat.11o 11’ N, Long. 07038’ E, 686m above sea level), Samaru-Zaria and Jaji Military Cantonment Farm located at 30 Km from Zaria along Kaduna – Zaria road (Lat. 10o 49’ 25” N, Long. 07o 34’ 10” E, 600m above sea level), both in Northern Guinea Savannah of Nigeria, during 2016 wet season. The treatments were factorially combined and laid out in a randomized complete block design (RCBD) with three replications. SAMMAZ 16 recorded significantly highest grain yield (3237.3kg/ha) over SAMMAZ 14 with (3002.5kgha-1) and SAMMAZ 15 with (2513.8kgha-1) and application of second dose of N fertilizer at 6 WAS recorded highest grain yield than other timings evaluated. Correlation coefficient in maize revealed at both locations that grain yield of maize was positively correlated with yield components. All the yield components are positively correlated with grain yield except crop growth rate (CGR) at Samaru and Leaf area index/Dry matter weight at Jaji. Among the varieties tested in this trial, SAMMAZ 16 and time of second dose of nitrogen fertilizer application at 6 WAS appeared to be the optimum for increased maize grain yield production in the Savannah region of Nigeria.  Based upon correlation, harvested cob weight and 100 grain weight were found to be suitable for selecting a maize variety for higher grain yield along with other attributes i.e. plant height, dry matter production, number of leaves and crop growth rate.
