ThesisItem Open Access Soil and Foliar Application of Boron on Growth and Yield of Sesame (Sesamum indicum L.)(University of Agricultural Science, Dharwad, 2016-07) Akshatha, S.; Rajkumara, S.A field experiment was conducted during the kharif season of 2015at UAS, Dharwad to study the effect of soil and foliar application of boron on growth and yield of sesame. The experiment was laid out in FRBD with six treatments. Soil application of borax (1, 2 and 3 kg/ha) along with and without FYM enrichment and foliar application of 0 and 0.2 % solubor spray at flowering stage was compared with control. Significantly higher seed yield of 956 kg/ha was obtained with application of RDF (FYM @ 5 t ha-1 + 50: 25: 25 kg ha-1 N: P2O5: K2O) + 3 kg/ha borax soil application. Enriching the FYM with 2 kg or 3 kg /ha of borax (832 and 936 kg/ha respectively) was better in comparison to 1 kg borax (722 kg/ha). Solubor foliar spray of 0.2 per cent recorded the higher seed yield (917 kg/ha) compared to no foliar spray (824 kg/ha). Seed yield per plant, length of capsule, number of capsules per plant and stalk yield followed the same trend with soil and foliar application of boron. Higher oil content was found with the application of RDF +FYM enriched with 1 kg borax/ha (52.18 %). Foliar spray of solubor at flowering stage did not influence the oil content of sesame but higher oil content was with the spray (51.54 %). Interaction was significant for oil content. Higher oil content of 53.55 % in RDF + 2 kg borax/ ha without solubor spray. Higher net returns was found with the application RDF + 1 kg borax soil application along with 0.2 % solubor foliar spray (` 41,108/ha) with a benefit cost ratio of 3.03. Application of RDF alone resulted in lower net returns (` 25,410/ha) and B:C ratio of 2.51.
