Description |
Greenhouse studies were conducted on two different alfisols, Bajaura (Loam) and Junga (Sandy loam), that are deficient in boron (B) for cauliflower (Brassica oleracea L. var. botrytis). The calcium:boron (Ca:B) ratio in cauliflower leaves with applied B (1 to 3 mg kg−1 soil) varied from 1276 to 521 in the Bajaura soil with high exchangeable-Ca and no deficiency or toxicity symptoms were evident. In the Junga soil with low exchangeable-Ca, however, the Ca:B ratio varied from 505 to 223 with toxicity symptoms visible when 2 and 3 mg kg−1 B has been applied. This corresponds to a Ca:B ratio of 256 and 223. Farm yard manure application showed an ameliorating effect on Ca:B ratio with a tendency to decrease a high Ca:B ratio in the absence of B application and increase a lower Ca:B ratio when incorporated with higher levels of B. The B mobility from leaves to curd decreased with increasing levels of B application and thus provided a circumstantial evidence for B retranslocation under conditions of low B supply i.e. conditional mobility.
