Influence of foliar application of boron on growth and yield of beetroot (Beta vulgaris L.)

The present investigation entitled “Influence of foliar application of boron on growth and yield of beetroot (Beta vulgaris L.).” was carried out at Hi-Tech Unit, Department of Horticulture, Rajasthan College of Agriculture, MPUAT, Udaipur. The twelve treatments comprising of various combinations of 4 levels of boron, viz., B0 - 0, B1 - 100, B2 - 150 and B3 - 200 ppm and three spray application times, viz., D1 - 30, D2 - 45 and D3 - 60 DAS. The treatments for beetroot crop were evaluated with three replications under factorial randomized block design. The experimental results show that different concentrations of boron, application times and their combinations significantly affected the growth, yield and quality of beetroot. The results showed that among different combinations of concentration of boron and time of boron spray, maximum plant height (41.48 cm), number of leaves (14.53), length of root (14.66 cm), diameter of root (10.31 cm), fresh weight of tops (140.42 g), fresh weight of roots (190.67 g), leaf area index (4.80), yield per plot (47.67 kg) and yield of root (476.68 q/ha) were recorded with treatment B3D1 (200 ppm boron spray at 30 DAS). Boron increases metabolic activity in plants, as well as growth and yield.
