Sodium chloride increases the yield of fodder beet (Beta vulgarisL.) in two New Zealand soils

Abstract

Fodderbeet(BetavulgarisL.)wasgrown on two New Zealand soils (Inceptisols) to which five rates of sodium chloride (NaCl) were added (0, 295, 590,885, and 1180 kg/ha). Yields offresh roots and fresh sugar trends increased linearly with increasing rates of NaCI in the Templeton soil but the highest yield occurredat295 kg NaCl/ha in the Wakanui soil and decreased at higher rates. In both soils, the sugar concentration was unaffected. The difference between soils was attributed to differences in soil chloride (CI) status and CI inputs from irrigation water (Templeton: 5 kg CI/ha; Wakanui: 33 kg ClI ha). CI inputs from rainfall during the cropping period were similar at the two sites (Templeton: 37 kg Cl/ha; Wakanui 41 kg Cl/ha). Overall, yield responses observed from NaCI applications were mainly a result of Cl. In both soils, NaCI applications increased CI concentrations linearly, but did not affect sodium or potassium concentrations in tops or roots.

Effects of potassium, sodium and chloride fertiliser rates on fodder beet yield and quality in Canterbury

“…The proportions of bulb (0.83) and leaf (0.17) to total DM yield, and their respective DM% of about 17% at Bankside were similar to those reported by Matthew et al (2011) and Goh & Magat (1989) for 'Rivage' and 'Trestel' fodder beet cultivars, respectively. The differences in the mean leaf DM% between the sites in the current experiments can be related to the different cultivars used, as Matthew et al (2011) used the same cultivar as at Bankside with the same results.…”

“…Stephen et al (1980), working with complete mixtures of nutrients, showed that both bulb and shoot DM were affected by the withdrawal of nitrogen, phosphorus and sodium (Na), but did not respond to the withdrawal of other nutrients. Relevant local research on the effects of chloride fertilisers (Goh & Magat 1989;Magat & Goh 1988), has demonstrated increased tissue mineral concentration and uptake of potassium (K), Na and chloride (Cl) but with variable and inconsistent DM yield response. Although these data are important in understanding the growth requirements for fodder beet in New Zealand, it is not clear whether these responses are due to the effects of single elements or their interactions.…”

Comparing salt tolerance of beet cultivars and their halophytic ancestor: consequences of domestication and breeding programmes

“…The RGR of sea beet at 10 dS m −1 was higher than that at 0.4 dS m −1 ; analysis of pooled RGR data (‘all cultivars') for sugar beet demonstrated an increased RGR at 5 dS m −1 when compared with that at 0.4 dS m −1 . Similarly increased growth rate of the sea beet under ‘mild salinity’ (EC 5.5 dS m −1 in Hajiboland et al (2009) ) when compared with the control treatment has been reported in field studies by Goh and Magat (1989) , Almodares and Sharif (2005) , Sepaskhah et al (2006) , Hajiboland et al (2009) and Szulc et al (2010) . The detailed physiological background of such NaCl-stimulated growth remains unclear ( Flowers and Colmer 2008 ; Rozema and Flowers 2008 ; Katschnig et al 2013 , 2014 ; Rozema and Schat 2013 ).…”

Dry matter intake and body condition score change of dairy cows grazing fodder beet, kale and kale-oat forage systems in winter

“…The DM yield of fodder beet of 18.5 and 21.8 t DM/ ha in 2012 and 2013, respectively, are within the range of 11 to 27 t DM/ha reported in an early study (Goh & Magat 1989) but less than the average DM yield of 32.8 t DM/ha found in a recent study by Chakwizira et al (2012). The lower DM yield may reflect the cultivar used ('Rivage' vs 'Colesse') and soil type (Balmoral stony loam vs Waimakariri sandy loam) between the current study and that of Chakwizira et al (2012).…”
