Effect of Sowing Methods and Weed Control Treatments on Growth of Sugar Beet and Weed Characters Under Nitrogen Fertilizer Levels

Abstract

Two field experiments were carried out at Kafr El-Hamam Research Station, Zagazig district, Sharkia Governorate, Agricultural Research Center during 2008/2009 and 2009/2010 seasons to study the effect of sowing methods (manual and mechanical), weed control treatments (one hand hoeing, Goltix 70 WG (metamitron) as herbicide, Goltix + one hand hoeing and two hand hoeing) and nitrogen fertilizer levels (60, 80 and 100 kg N/fed) on growth of sugar beet (Beta vulgaris L.) cv. Hanrike as well as weeds characters. The obtained results could be summarized as follows: 1. Mechanical sowing method of sugar beet by planter machine significantly surpassed the traditional sowing method (manual) in all studied growth and minimized weed characters in both seasons. 2. Controlling weeds associated with sugar beet plants by two hand hoeings before the second and the third irrigations significantly recorded the highest values of studied growth attributes and minimized weed characters in both seasons. While, using Goltix 70 WG (metamitron) as herbicide + one hand hoeing before second irrigation came in the second rank in this respect in both seasons. On the other hand, the lowest values of all growth attributes and weed characters were resulted from the control treatment (one hand hoeing) in both seasons. 3. Fertilizing sugar beet plants with 100 kg N/fed significantly increased all studied growth and weed characters and markedly recorded the highest values of these characters in both seasons. However, application of 60 kg N/fed produced the lowest values of all studied characters in the two growing seasons. From the obtained data in this study, it can be concluded that sowing sugar beet using mechanical sowing method (planter machine), controlling weeds by hand hoeing at two times and mineral fertilizing with 100 kg N/fed could be recommended in order to maximize its growth attributes and reduce weed growth under the environmental conditions of Sharkia Governorate.

Effect of different single herbicide doses on sugar beet yield, quality and associated weeds

“…Also, he added that the total broadleaf and total broadleaf and grassy weeds were significantly reduced by 54 and 91%, respectively, compared to untreated check in the second season. Our findings are consistent with those obtained by Attia et al (2011), Vasel et al (2012), Wujek et al (2012) and Deveikte et al (2015).…”

“…Similar results were obtained by Soroka and Gadzhiev (2006) who reported that when sugar beet and weeds grow together 30 days after emergence of sugar beet, the root yield decreased by up to 45%. Also, Attia et al (2011) and Majidi et al (2011) reported that the use of herbicides may reduce yield losses, as herbicides can reduce the weed infestation. Mehmeti (2004) showed that using a combination of broadleaved herbicides caused weeds to be controlled and root yield to be increased.…”

Effect of nutrients management on yield attributes of fodder beet under sandy soil conditions.

“…This may be due to nitrogen affects growth and in turn on root weight through its effect on cell division, expansion, and elongation resulting to large leaves and enhanced root weight/plant. These findings were in harmony with those reported by Geweifel and Aly (1996), Abdallah and Yassen (2008), Attia et al (2011), Shalaby et al (2011), Hussein and Hanan (2012, Kassab et al (2012), Sakr et al (2014), Shaban et al (2014, Abdelaal and sahar (2015), Merwad (2015), Enan et al (2016), Khatab et al (2016, Aly et al (2017), Abdel-Lateef (2018) and Nemeata Alla (2018. The interaction between humic acid treatment and NK treatment (H×F) was significant regarding root fresh weight trait in the both seasons (Table 7).…”

“…This may be due to nitrogen affects growth and in turn on yield through its effect on cell division, expansion, and elongation resulting to large leaves and enhanced yield (Onyango, 2002). These findings were in harmony with those reported by Geweifel and Aly (1996), Abdallah and Yassen (2008), Attia et al (2011) values of top fresh weight/plant (1100 and 701g in the two respective seasons) were obtained from H2F9 and H1F9 respectively. Otherwise, the lowest mean values in this respect (490 and 227g) were obtained from H0F1treatment.…”

Agronomic Performance Sugar Beet ( Beta vulgaris L.) in Egypt Using Inorganic, Organic and Biofertilizers

“…Monreala et al (2007) stated that the highest values of quality parameters were achieved from the lowest level of nitrogen application (30 kg N/ha). Meanwhile, Abou Zeid & Osman (2005), Seadh (2008); El-Sarag (2009); and Attia et al, (2011) found that bacterial inoculation of sugar beet seeds caused insignificant increases in either root quality or growth parameters, while significant increase was registered in root and sugar yields/fed. There is high potential for using sugar beet to reducing the imported sugar from abroad.…”
