Sugar beet yield and quality as affected by concentration of boron and methanol application.

Abstract

The aim of this research is to assess the effect of foliar spraying with boron and methanol levels and time of methanol application. Two field experiments were conducted at EL-Haamoul district Kafer EL-Sheikh Governorate, Egypt during 2012/2013 and 2013/2014 seasons. Strip-plot design was used in both seasons. Main plot (vertical) allocated with Boron levels (0, 1 and 1.5 Kg/fed.) sub plot (horizontal plots) takes Methanol rates (15%, 30% and 45% v/v) this solution were sprayed overhead 3 times in two weeks intervals starting after 55 and repeated at 70 and 80 days from sowing with (zero, one, two and three times) were distributed in sub-sub plots. Obtained results indicated that addition boron on foliage as foliar spraying at rate of 1.5 Kg/fed. Significantly increased affected on the values of most characters under study i.e. root dimension, yields of root, top and sugar per fed. In additions to impurities (Na, K and α-N) and quality traits as sucrose and sugar losses percentages. On the other hand purity and extractability percentage gave the highest values with control treatments. This was true in both seasons. Application of methanol solution at level 45% take the mentioned trend of boron and gave the highest values 45% compared with level 15% which recorded the lowest values with purity and extractability percentages. Times of foliar applications of methanol on sugar beet leaves at three times recorded the highest values for most traits as boron and methanol levels except impurities content (Na, K, α-N). alkalinity, purity, extractability% which recorded in significant effect on values of these traits in both seasons. Whereas, sugar losses% showed significant increase in the second season only, sugar extractable% and sugar yield (ton/fed.). Significant interaction effects were found between factors under study on some traits in both seasons.

OBIAL AND ENZYMATIC ACTIVITIES OF SOYBEAN EFFECT OF PLANT SPACING AND FOLIAR APPLICATION WITH BORON ON YIELD AND QUALITY OF TWO SUGAR BEET (Beta vulgaris, L.) VARITIES

“…The pronounced effect of boron on root length may be due to its effect on the growth which in turn affect root length of sugar beet. The results of boron on root length obtained in the study are in agreement with those obtained by Ahmed ( 2005), Moustafa and Omran (2006), Taha et al (2013) andNemeat Alla et al (2016).…”

“…This finding may be due to the healthy role of boron on the plant grown which directly affected growth vigor of the plants. This result is in harmony with those obtained by Ahmed (2005), Moustafa and Omran (2006), Taha et al (2013) andNemeat Alla et al (2016). reported that top yield was significantly affected by boron.…”

“…The increase in value of root yield as a result to the increase in boron lewef application could be due to the favorable effect of boron element on growth criteria in af root diameter and root fresh weight (Tables 3 and 4). These results agreed with those of Ahmed ( 2005), Moustafa andOmran (2006), Vince Lawson (2008); Taha et al (2013) and Nemeat Alla et al (2016).…”

“…The relative advantage of boron element on root thickness may be due to the distinct role on photosynthates translocation process. In those connection Ahmed ( 2005), Moustafa and Omran ( 2006), Taha et al (2013) andNemeat Alla et al (2016). they reported that root diameter increased by increasing boron levels.…”

Influence of Plant Density and Nitrogen Fertilizer Rates on Yield and Yield Components of Beetroot (Beta vulgaris L.)

“…In addition, Sogut and Arioglu [9] reported that plant density at 148 148, 111 111, and 88 889 produced higher root yields than 74 074 and 63 492 plants per hectare. Nemeat-Alla [10] reported that planting sugar at a population of 100 000 plants ha −1 caused significant increases in root diameter but did not affect root length and total soluble solids. On the other hand, Bhullar et al [11] stated that the plant population of 100 000 plants ha −1 produced the lowest beetroot diameter and highest root length and root yields.…”
