Abstract
A field experiment was conducted during rabi 2022 on carrot variety ‘Super kuroda’ in sandy loam soil at Horticultural Garden, Professor Jaya Shankar Telangana State Agriculture University, Rajendranagar, Hyderabad. To study the effect of seaweed extract on the growth parameters of carrots. The experiment was laid out in randomized block design (RBD) with eight treatments and replicated thrice. The treatments include various sources of biostimulants viz., Seaweed extract liquid, seaweed granules, vermicompost and vermiwash given as foliar application on three stages viz., first spray on 2-3 leaves stage and thereafter at every 20 days interval and as soil application twice at the time of sowing as well as 30 DAS.The various growth parameters were recorded. The results revealed that on application of RDF + soil application of seaweed extract twice at the time of sowing and at 30 DAS + foliar spray thrice 2.5 ml l-1 of water significantly increased the growth parameters viz., plant height, number of leaves per plant, chlorophyll content.
Keywords: Carrot, seaweed extract, plant height, number of leaves per plant, chlorophyll content
