A field experiment was carried out at Perampattu coastal farmer’s field during July-October, 2018, to study the effect of boron and silicon fertilization on the growth, yield and nutrients uptake by tomato in coastal saline sandy soil. Texturally, the experimental soil was sandy loam and taxonomically classified as Typic Ustifluvent with initial soil characteristics (0-15 cm layer) of the experimental site were, pH–8.41 and EC–2.85 dS m-1. The soil registered low organic carbon status of 2.31 g kg-1, 134.56 kg ha-1 of alkaline KMnO4 –N; 9.43 kg ha-1 of Olsen–P and 159.31 kg ha-1 of NH4OAc-K, respectively. The available hot water soluble B content of 0.07 mg kg-1 and silicon content of 84.0 mg kg-1 in soil. The various treatments included were, T1- Control (RDF alone), T2 –RDF + Composted coirpith (CCP) @ 12.5 t ha-1, T3–RDF + Borax @ 15 kg ha-1 + Silixol granules @ 20 kg ha-1 soil application (SA), T4-RDF + Borax + Silixol granules foliar application (FA) @ 0.5% twice at pre-flowering (PFS) and flowering stage (FS), T5 -RDF + CCP + Borax @ 15 kg ha-1 + Silixol granules @ 20 kg ha-1 (SA), T6-RDF + CCP + Borax + Silixol granules (FA) and T7–RDF + CCP + Borax + Silixol granules (SA+FA). The above treatments were arranged in a Randomized Block Design (RBD) with three replications and tested with tomato var. Shivam hybrid as test crop. The results of the study clearly indicated that the yield benefit of the treatment (T7), combined application of recommended dose of NPK fertilizer + borax @ 15 kg ha-1 + silixol granules @ 20 kg ha-1 (SA) through soil as well as foliar spray of borax @ 0.5% + silixol @ 0.5 per cent twice at pre flowering and flowering stage along with CCP @ 12.5 t ha-1 superior in increasing the growth, yield and nutrient uptake by tomato.
