RESPONSE OF YIELD AND ITS COMPONENT OF FOUR MAIZE CULTIVARS FOR FOLIAR SPRAYING WITH GLUTATHIONE
Abstract
A field experiment was conducted in the experimental field affiliated to the college of Agricultural Engineering Sciences, the University of Baghdad, Jadrya during the fall season 2018 to investigate the response of the yield of four varieties of corn to the spray of glutathione. The Randomized Complete Block Design (RCBD) was used with three replications in order of factorial experiments. The experiment included two factors, the first was represented by four maize varieties (Fajer 1, Baghdad 3, 5018, and Al-Maha) and the second by four Glutathione concentrations 0, 100, 200, and 300 mg.L-1 sprayed at the two plant stages of 6 and 12 leaves for 75% of the total plants. The results showed a significant difference among varieties, The variety 5018. was superior in most of yield traits. So It produced the highest averages of the traits, ear length 20.79 cm, number of rows per 18.433 rows. ear-1, number of grains per a row 77.6 grains.row-1, area unit yield 9.076 Mg.ha-1, and biological yield 18.202 Mg.ha-1 compared to the other varieties. The Spraying with Glutathione had significant effect on the yield and its components. The concentration 300 mg.L-1 was superior in the most studied traits such as ear number 1.800 ears.plant-1, ear length 20.78cm, row number per an ear 19.317 rows.ear-1, 100-grains weight 32.68g, area unit yield 9.202 Mg.ha-1, and biological yield 19.500 Mg.ha-1, whereas the plats treated by spraying 200 mg.L-1 of Glutathione gave the highest averages of the traits, number of grains per a row and number of grains per an ear 44.82 grains.row-1and 809.ear-1 respectively, and the spray treatment 0 mg.L-1 gave the lowest averages of the most studied traits. We can conclusion from this study, it can be foliar spraying maize plants 5018 variety with 300 mg L-1 concentration from glutathione, because it improved from yield traits and its components.
