Response of sugar beet to some mechanical management practices, irrigation and plant densities

Abstract

The aim of this study was to see the effect of four mechanical practices (shallow ploughing, laser deep ploughing and laser leveled soil + deep ploughing), three irrigation intervals (every 4 weeks, every 6 weeks and every 8 weeks) and three plant densities (35 cm (20000), 25 cm (28000) and 15 cm (46000) plants/fed.) on growth of sugar beet plants of Farida cultivar. Sowing of sugar beet at a laser leveled soil + deep ploughing, among lower plant densities 20.000 plants/fed (1 feddan = 0.42 ha) and irrigation intervals every 8 weeks gave a significant increase in root length, root perimeter , crop growth rate(CGR) and relative growth rate(RGR) in comparison to other treatments.

Influence of Drip Irrigation Management on Sugar Beet Yield and Some Water Relations at North Nile Delta

“…In the present study indicated that, proportionately; higher root length and lower root diameter might be possible by the application of relatively low amounts of irrigation water. Similar observations were reported by El-Maghraby et al (2008), Abo-Shady et al (2010 and Baigy et al (2012). Results reveal that water consumptive use increased with decreased intervals of irrigation, these obtained results were in good agreement with those of Rinaldi and Vonella (2006), Isoda (2007) and Hassanli et al (2010).…”

Effects of irrigation and nitrogen on chlorophyll content, dry matter and nitrogen accumulation in sugar beet (Beta vulgaris L.)

“…Proper irrigation can continuously increase the dry matter and nitrogen accumulation in crops during the whole growth period 48 – 50 . For example, Wang et al 51 found that irrigation significantly affected the nitrogen accumulation and grain yield in wheat.…”

Influence of stem cuttings, spacing, group planting, light, irrigation and harvesting period on yield in Plectranthus vettiveroides (K.C. Jacob) N. P. Singh & B. D. Sharma

“…Watering schedule more or less has no effect on plant growth may be due to the reason that water more than the optimum level cannot be utilized by the plant. Root length was recorded maximum when irrigated once in two days may be due to the reason that prolonged watering intervals lead to water deficit in soil and root will show a tendency to elongate for absorbing water from deep soil [23,24,25]. Maximum fresh root biomass was recorded when irrigated daily thrice that may be due to the presence of higher amount of water content in the root [26].…”
