Evaluation of Growth , Yield and Yield Components of Six maize Genotypes in Khartoum state

Abstract

A field experiment was carried out at the demonstration farm of College of Agricultural Studies, Sudan University of Science and Technology during the winter season (2014-2015). The experiment was aimed to evaluate six genotypes of maize (Zea mays L.) for growth , yield and yield components. The experiment a randomized complete block design (RCBD) with three replicates was layed out. The treatments were: Var 113, Mugtama 45, Sweet corn, Golden corn, Hudiba 1 and Hudiba 2.The growth parameters studied included: Plant height, Number of leaves, Stem diameter and Leaf area. Yield components were: Grains weight /cob, 100 grain weight, Number of grains /cob, Number of rows/cob, Number of grains/line and yield t/ha. All genotypes obtained showed significant difference in plant height in both 30 and 45 days. Also Var 113 and Hudiba 2 have significance difference in number of leaves per plant over all other genotypes. Var 113, Hudiba 2 and Sweet corn gave significan difference in leaf area in 30, 45 and 60 days. There are no significan difference in Stem diameter, Grains weight /cob, Number of grains /cob and Number of rows cob, but there was significant difference in both Number of grains/line and yield( t/ha).
