Nutrient management plays a crucial role in the yield and quality of sweet corn. A field experiment was conducted during the years 2018 and 2019 to investigate the effect of organic and standard sources of fertilizer on the yield and quality of sweet corn within the new soil of West Bengal, India. The organic sources (OS) of fertilizer were vermicompost (VC), (Ascophyllum nodosum) Soligro granular (OS1), Bioenzyme liquid (OS2), and Opteine (Ascophyllum nodosum) filtrate (OS3). The traditional input was chemical fertilizer (CF) applied at the recommended dose of 150:75:75 kg ha-1 of N: P2O5:K2O for the sweet corn. The organic source VC was wont to supply 100% N recommendation as one source or 50% N recommendation when combined with CF or organic sources. Maximum fruit yield was recorded when recommended dose of Fertilizer (RDF) CF was applied at full dose, which was on a par with 50% recommended dose of chemical fertilizer together with 50% recommended dose of vermicompost on a nitrogen equivalent basis and VC at the total recommendation. A better percentage of large-size cob (> 25 cm) was obtained in VC-based treatments compared with CF treatment. Vermicompost at full dose increased antioxidant, carotenoid, and phenol content compared with its half dose together with other sources. The potential exists to enhance sweet corn cob quality through better nutrient management, whether or not it's conventional, organic, or a mix of both. |
