Yield and Quality of Some Promising Sugarcane Varieties as Affected by Planting Pattern

Abstract

The present study was carried out at El-Mattana Agriculture Research Station Qena Governorate, Upper Egypt in 2007/2008 and 2008/2009 growing seasons to evaluate three sugarcane varieties (two promising varieties viz. G. 98-28, Phil. 8013 and the commercial variety G.T. 54-9) grown at three planting pattern; whole stalk as one, two and three pieces. Treatments were arranged in a split-plot design with three replicates. The main plots were assigned to three sugarcane varieties while planting pattern were distributed in the sub plots. Results showed that sugarcane varieties were significantly differed in stalk diameter, sucrose percentage and sugar yield ton/fed in the second season only. Cane yield was significantly affected by grown varieties in both seasons. Phli. 8013 showed superiority in all significant traits. Under this study as compared with of her varieties planting pattern were significantly affected in all studied traits except stalk height, brix and sucrose percentages in the second season and number of millable cane/m 2 in both seasons. Planting sugarcane with by cutting cane stalk into three pieces gave the highest values in all studied traits except, stalk diameter which obtained with planting whole stalk. The interaction effect between varieties and planting pattern was insignificant in all studied traits except in purity percentage in the first season. The height values were obtained when planting Phli.8013 variety by cutting cane stalks into three pieces. Under conditions of the present work, growing sugarcane varieties i.e., G.T. 54-9, Phil. 8013 and G. 98-28 by cutting cane stalk into three pieces recommended for getting the highest cane and sugar yields/fed.

Effect of Harvesting Age on Yield, Yield Components and Quality of Some Promising Sugarcane Varieties.

“…This observation was true in the two sugarcane crops. This result is in accordance with those reported by Sohu, et al (2008); Ahmed, et al (2011) and Yousif, et al (2015) they found that significant differences in millable cane diameter were found among the tested sugar cane varieties.…”

“…This result may be due to the genetic differences among varieties in their ability of the formation of stalks which reflected in stalk which reflected in stalk height and stalk cane millable cane diameter as shown in Table (1and 2). The results of the present investigation are in line with those of Ahmed et al )2011(;Galal, et al (2015) and Yousif, et al )2015) they found that G.T.54-9 variety was superior to the two other varieties in stalk weight.…”

“…While the variety of G. 98-28 gave the lowest sucrose percentage in plant cane and first ratoon crops. The differences among varieties in sucrose percentage depend on the interaction between varieties and environmental factors during growth, sucrose formation and storage periods.The differences among sugar cane varieties obtained by Kumara and Bandara (2002); Ahmed, et al (2011) and Mehareb, et al (2016) they found that significant differences among evaluated cane varieties for sucrose percentage. Sucrose percentage was significantly affected by the interaction between harvesting age and varieties in the two crops.…”

“…al. )2008(;Ahmed, et al (2011) and Yousif, et al )2015 (they pointed out that the significant variance between the sugarcane varieties in stalk height in both seasons. Table (1) cleared that the interaction between varieties and harvesting age was significantly in both of plant cane and first ratoon crops.…”

“…The new sugarcane varieties is considered one of the essential wings for Production. Many investigators pointed out the important role of varieties in respect to their influence one yield and quality (Kumara and Bandara 2002 ;Sohu, et al 2008;Ahmed, et al 2011;Islam, et al 2011;Galal, et al 2015;Yousif, et al 2015 andMehareb, et al 2016).…”
