Effect of Cobalt and some Vitamins as Foliar Application Treatments on Productivity and Quality of Williams Banana Cultivar

Abstract

This study was conducted during two successive seasons (2012/2013 first ratoon and 2013/2014 second ratoon) on Williams banana cultivar grown in clay loam soil under flood irrigation system in a private banana orchard located at El-Hagabey district, Meet Ghamr Dakahlia Governorate, at 3x3.5 m apart. Forty five stools/(mat) ,each containing two plants of Williams cultivar were chosen to evaluate the effect of foliar spray with Cobalt , Vit B 12 and ascorbic acid ( Vit C) singly, double or in triple combinations, beside control treatment on yield and fruit quality of the tested Williams banana cv. These treatments were arranged in a randomized complete blocks design with three replicates. The obtained results could be summarized as follows:Sprayed banana plants with the mixture of cobalt sulphate + Vit B 12 + Vit C at 50+50+500 ppm each (T 14 ) recorded increases in bunch weight, yield /fed. and number of fingers /bunch were about 63.34 , 65.49 and 15.22 % over control treatment, respectively. The plants which sprayed with the mixture of cobalt sulphate + Vit C at 100+1000 ppm each (T 11 ) gave the highest values of hand and finger weight and recorded increases about 54.00 and 62.82% over control treatment, respectively .The highest values of total sugars , SSC/TA and Vit.C were obtained by the plants which sprayed with cobalt sulphate + Vit B 12 + Vit C at 100+100+1000 ppm each (T 15 ) average two seasons and recorded the relative increases were about 24.62, 100.56 and 44.34% over control, respectively.

Effect of Yeast and Ascorbic Acid Application on Growth and Fruiting of Williams Banana Plants

“…The above mentioned findings are in accordance with those obtained by Samiullah (1988), Ahmed et al (2003), Mostafa (2004), Abdel-Rahman (2005), Merwad (2011) and El-Baz et al (2016). They revealed that some vitamins foliar spray enhanced the growth, nutritional status and improved the yield and fruit quality of banana plants.…”

“…Ascorbic acid has an auxinic action and synergistic effect on flowering and fruiting of fruit trees as well as, ascorbic acid is a natural and safety used instead of synthetic auxins. Six sprays of 100 ppm ascorbic acid were very effective in improving the yield of banana plants (Alscher et al, 1997;Ahmed et al, 2003;Mostafa, 2004;Abdel-Rahman, 2005;Marwad, 2011 andEl-Baz et al, 2016).…”

“…Recentemente, tem sido constatado uma participação de forma indireta das vitaminas sobre o desenvolvimento da planta, aumentando os níveis endógenos de Irriga, Botucatu, v. 1, n. 1, p. 79-91, Edição Especial 30 anos PG Irriga, 2018 vários fatores de crescimento, como citocininas e giberelinas (EL-BAZ et al, 2016). Sendo que, a variação de sua disponibilidade afeta a biossíntese de hormônios, absorção de nutrientes, água, bem como a síntese de clorofila e proteínas (SAMIULLAH; ANSARI e AFRIDI, 1988).…”

Effect of Spraying GA3 and Cyanocobalamin (Vit. B12) on Fruit Set, Yield, and Fruit Quality of Le-Conte Pear Trees

“…Since methionine synthase is also required for both the regeneration and the biosynthesis of Met. It is the convergence point for two major biochemical domains in cellular metabolism, the Met biosynthetic pathway and the one-carbon cycle (E. E. T. El-Baz, Lo'ay, Ibrahium, & El-Deeb, 2016;Lo'ay, 2005;Zeh, Leggewie, Hoefgen, & Hesse, 2002). However, concerning to the effect of the GA3 and B12 on chlorophyll content, data in table 1.…”

“…It is the connectionpoint for two major biochemical spheresin cellular metabolism, the Met biosynthetic pathand the one-carbon cycle (Zeh et al, 2002). Many studies of cyanocobalamin were carried out on fruits to improve fruit quality attributes such Kaki fruit (Lo'ay, 2010 ), and in Thompson seedless (Lo'ay, 2011), and mango (Samaan et al, 2011), guava (Samaan et al, 2012), banana (El-Baz et al, 2016).…”
