Abstract:
The research was conducted during 2021season at a field in Talkalakh region in Western Area-Homs to investigate the effect of foliar spraying of different concentrations of bread yeast extract (0, 5, 10, 15, 20 g. l-1) on yield and its components of two genotypes of maize( Bassel1 and Bassel2). Split-plot design with three replications was used. Results showed that Bassel2 genotype surpassed on Bassel1 in: ear length(16.47)cm, ear diameter(4.45)cm, number of rows per ear(14.37)rows, number of grains per row(28.04) grains, ear weight(90.48)g, grains weight per ear(75.81)g, weight 1000 grains(163.70)g, shelling percentage(83.74%) and grain yield(4120.85)kg/ha.. Spraying of yeast extract caused a significant increase in all studied parameters compared with control and 15g/l treatment exceeded in : ear length(16.47)cm, ear diameter(4.63)cm, number of rows per ear(12.57)rows, number of grains per row(28.72) grains, ear weight(88.20)g, grains weight per ear(74.13)g, weight 1000 grains(164.61)g, shelling percentage(83.94%) and grain yield(4181.17) kg/ha. The interaction between Bassel2 genotype and spraying15g. l-1 of yeast extract gave the best results and highest grain yield(4318.17)kg/ha compared with other treatments.
