Distribution of boron and its uptake in the plant parts of two tomato varieties

Abstract

 The effect of micronutrient boron application on dry matter yield, uptake and distribution in the plant
 parts of two tomato varieties (Roma VF and Dandino) were studied in a rainfed trial. Results obtained
 showed variations in boron distribution among plant parts.  The concentration of boron ( B )  ranged
 from  6.0-109.0, 5.8-18.3 and 3.1-13.6 mgkg-1, in leaves, stem and roots, respectively. The effect of born
 rates on the DMY, B. concentration and uptake was highly significant (P=0.010) on the leaves and stem,
 but not on the roots. The concentration of B in both varieties was more in the leaves, than in the stem.
 The roots had the least B concentration. Among the varieties. Dandino, recorded higher B concentration
 in the various plant parts than Roma VF. Application of B increased fruit yield of tomato fruit by 233
 and 192 % relative to the control for Roma VF and Dandino varieties respectively.
