Abstract:
A field experiment was conducted during zaid season of 2020 and 2021 at crop research farm in Department of Agronomy, Naini Agricultural Institute, SHUATS, Prayagraj on sandy loam soil to investigate the response of seaweed sap foliar application on maize cultivars under eastern UP condition. The experiment was laid out in Split Plot Design along with two factor viz., four maize cultivar (VMH-27, VMH-53, VLMH-57 and VLQPMH-59) as main plot and two seaweed (Kappaphycus sp. & Sargassum sp.) sap at different concentration (5%, 7.5% & 10%) as sub-plot factor treatment along with one water spray and their combination of 28 treatments replicated thrice. Each main plot (4 plot) was divided into 7 subplots to allocate the different concentration of both sap, i.e. 5, 7.5, 10% and water spray along with recommended dose of nutrients. Pooled results indicated that foliar application of seaweed extracts at different concentrations (5.0, 7.5 and 15.0% V/V) significantly enhanced the growth and yield of maize cultivars. Cultivars V₃: VLMH-57 which produced maximum plant height (186.67 cm), number of leaves/plant (11.99) and grain yield (5868.17 kg/ha). While, foliar application of S₇: S-Seaweed sap 10% (Sargassum sp. sap) were produced highest plant height (181.62 cm), number of leaves/plant (12.00) and grain yield (5427.59 kg/ha).
