Abstract: A field trial was conducted at the Student’s Instructional Farm (SIF) of Chandra Sekhar Azad University of Agriculture and Technology, Kanpur during Kharif Season of 2018 to find out the used time of sea weed extract (Ascoplyllumnodosum) to soil health improvement, root development and economics on paddy. The experiment comprises of ten treatments combinations viz. Control (RDF), RDF + SoliGro Gr @ 10 kg/ha at FLP, RDF+SoliGro @ 10 kg/ha at 25 DAT, RDF+SoliGro @ 10 kg/ha at 45 DAT, RDF+SoliGro @ 10 kg/ha at 65 DAT, RDF+SoliGro @ 10 kg/ha at FLP & 25 DAT, RDF+SoliGro@ 10 kg/ha at FLP & 45 DAT, RDF +SoliGro @ 10 kg/ha at FLP &65 DAT, RDF+SoliGro @ 10 kg/ha at FLP, 25 & 45 DAT, RDF+SoliGro@ 10 kg/ha at FLP, 25, 45 & 65 DAT. The field was laid out in Randomized Block Design with three replications. The paddy variety NDR-359 was transplanted at spacing of 20cm×10cm a part. Results observed that significantly higher root hairs/hill, was found with the application of RDF+ two times application of SoliGro Gr @ 10 kg/ha at final land preparation time and 25 days after transplanting of rice. The treatment of recommended dose of fertilizer along with two times applied SoliGro Gr @ 10 kg/ha at final land preparation time and 25 days after transplanting of rice crop statistically increased the grain yield, net income and return per rupee, compared to all remaining treatments, respectively.
