Impact of Various Nutrient Management Technique on Growth, Yield and Quality Attributes of Sweet Sorghum (Sorghum bicolor L.)

Background: These studies aim to determine the influences of various organic and inorganic nutrient sources on the growth, yield and quality attributes of sweet sorghum within the Indo-Gangetic region. Methods: The experiment utilized a randomized block design with ten treatments replicated three times. These treatments included various nutrient management strategies: two different doses of inorganic fertilizers (100% and 75% of the recommended dose) applied with or without zeolite, press-mud and bio-neema, as well as three foliar applications of nano NPK. Result: Among the nutrient management strategies, the application of 75% of the recommended dose of fertilizers (RDF) along with zeolite, press-mud and bio-neema showed a superior and significant improvement. This strategy enhanced growth attributes such as plant height by 23.73% and dry matter accumulation by 42.25%. It also improved yield attributes, including ear head length by 31.34%, grain yield by 53.25% and test weight by 30.67%. Furthermore, this treatment increased the Brix ratio by 37.67% and the juice extraction percentage by 39.04% compared to the control. This study underscores the crucial role of strategic nutrient management in sweet sorghum cultivation, demonstrating the most promising outcomes for enhancing growth, yield and quality.
