Field experiment was conducted to study the influence of organic manures and biofortification of selenium on growth, yield and selenium contentof cucumber (CucumissativusL.) during 2019 at Koneripalayam village in Perambalur district, Tamil Nadu. The popular variety Green Long suitable for this region was used for the present study. The experiment was carried out during two seasonsviz., Season I (February-May) and Season II (July-October)in randomised block design with fifteen treatments and three replications. The results of the experiment revealed that application of 25 tFYM ha -1 and 2 kg CBF ha -1 along with foliar application of Se (20 µg L-1) significantly recorded the highest vine length (209.1 cm and 214.6 cm), number of leaves (108.2 and 113.7), leaf length (15.7 cm and 15.9 cm) and leaf breadth (16.2 cm and 16.5 cm) in first and second season, respectively. The highest number of fruits per vine (13.3 and 16.5), fruit length (19.6 cm and 20.8 cm), fruit girth (17.1 cm and 18.2 cm), mean single fruit weight (78.1 g and 81.2 g), fruit yield vine-1 (723.5 g and 1009.2 g)and selenium content per fruit (8.1 µg kg-1 and 10.6 µg kg-1) in first and second season respectively was obtained with1 t EM ha -1 + 2 kg CBF ha -1 + Se (20 µg L-1) as foliar application. Among all the organic manures, farmyard manure was proved to be superior in respect of growth parameters and enriched manure in respect of yield parameters. The foliar application of selenium was found to be the best method of its supplementation in plants and relatively higher values of Se content in fruits were noted with higher dose of Se as folior application.
