Effect of Organic Manure and Potassium Fertilizer on Productivity and Quality of Fodder Beet (Beta vulgaris. L.) at South West Suez Canal

Abstract

Two field experiments were carried out during 2015 / 2016 and 2016 / 2017 winter seasons in the Kabret El-Bahara area -Suez Governorate, Egypt to study the response of fodder beet (Beta vulgari, L.) Rotta cultivar to the combination between four levels organic manure fertilizer treatments at a rates of 10, 20, 30 and 40 m 3 / fed and application with four levels of potassium fertilizer treatments (24, 36, 48 and 60 kg k 2 O / fed. Using the split-plot design which, the organic manure treatment were distributed in the main plots, whereas, the potassium fertilizer treatments in sub-plots in four replicates.The obtained results could be summarized as follows:The results showed that the higher levels of organic fertilizer gave the highest values and the best was the level of 40 m 3 / fed Compared to the level of 10 m 3 / fed In all the characteristics of the study at 100 and 150 days from sowing and also the characteristics of the yield and its components at harvest in both seasons.The increase of potassium fertilization added to soil at a rate of 60 kg k 2 O / fed resulted in the highest values of growth traits at (100 and 150 days from planting), yield and its components at harvests compared to the levels of potassium fertilization at the levels of 24, 48, 60 kg k 2 O / fed, respectively in both seasons.The results also showed that the addition of organic fertilization at a rate of 40 m 3 / fed along with potassium fertilization at a rate of 60 kg K 2 O / fed gave the highest values in the studded characteristics of growth, yield and its components in both roots and tops. It was also found that the increase in the protein content of the top and roots as well as total carbohydrates was detected due to the treatment 40 m 3 / fed organic fertilizer plus 60 kg K 2 O / fed added to the ground, respectively, in both seasons.Likewise the results revealed that the content of the top of nitrogen and potassium was highest in the roots and reached to the using the 40 m 3 / fed organic fertilizer along with 40 m 3 / fed potassium fertilization of 60 kg K 2 O/ fed.The results of the calculation of the economic yield of the crop showed that the cultivation of beet crop by using organic fertilization at a rate of 40 m 3 / fed plus potassium fertilization at a rate of 60 kg / K 2 O/ fed proved to be is the best experimental economic experiment for the farmers.

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).…”

“…Such effect of NK may be refer to its role in improving cell division and elongation which reflected on root elongation. These results are in according to Ibrahim et al (2002), Turk (2010, Albayrak and Yuksel (2010), Shalaby et al (2011), Hussein and Hanan (2012), Kassab et al (2012, Eman El-Sarag (2013), Shaban et al ( 2014), Abdelaal and sahar (2015), Merwad (2015), Nemeata Alla (2016), Mehanna et al (2017) and, Abdel-Lateef (2018.…”

“…Averages of top dry weight/plant as affected by humic acid application, NK treatment and their interaction in the two seasons are illustrated in Lateef (2018).…”
