Influence of Seaweed Sap and Organic Manures on Growth and Yield of Baby Corn

A field experiment was carried out during Rabi 2022 season at Crop Research Farm, Department of Agronomy, Naini Agriculture Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh, to study the response of Seaweed Sap and Organic Manures on Growth and Yield of Baby Corn. The treatments consists of three level of Seaweed sap (5%, 7.5% and 10%), Organic manures (FYM, Poultry manure, Vermicompost) and control. The experiment was laid out in Randomized Block Design (RBD) with ten treatments and replicated thrice. The soil of the experimental field was sandy loam with pH (8.0), EC (0.56 ds/m), Organic Carbon (0.62%), Available N (225 kg/ha), Available P (38.2 kg/ha), and Available K (240.7 kg/ha). The results showed that application of Seaweed sap (10%) + Vermicompost – 8.5t/ha recorded significantly higher plant height (167.58 cm), maximum dry weight (98.48 g), No. of cobs/plant (2.47), cob length (21.40 cm), Cob weight with husk (49.84 g/cob), Cob yield (11.03 t/ha) and stover yield (35.33 t/ha). Maximum gross returns (281216.67 INR/ha), net returns (216726.67 INR/ha) and Benefit Cost (B.C) ratio (3.36).
