Abstract

A field experiment was conducted at Karunya University in Coimbatore during the Rabi (2022) growing season to evaluate the impact of nano urea and neem-coated urea on the growth and yield parameters of sorghum. The experiment employed a Randomized Block Design with seven treatments and three replications. Among the treatments, the application of 50% N through neem-coated urea (NCU) + 50% N through nano urea (NU) + P and K demonstrated superior results, comparable to the treatment with 75% N through NCU + 25% N through NU + P and K. These treatments exhibited significant improvements, in plant height (242.1 cm), total dry matter production (14,481 kgha-1), leaf area index (0.95), grain yield (3,375 kgha-1), straw yield (9,843 kgha-1), higher gross return (Rs. 149,764ha-1), net return (Rs. 95,903 ha-1), and a benefit-cost ratio of 2.78.

Conclusion

Based on the field research findings, the application of 50% N through neem-coated urea + 50% N through nano urea, along with P and K, resulted in significantly higher grain and straw yields for sorghum in the southern region of Coimbatore. Additionally, the application of 75% N through neem-coated urea + 25% N through nano urea + P and K can be considered as the second option for achieving higher yields and improved economic returns in sorghum cultivation. This treatment exhibited favourable outcomes in terms of nutrient uptake, plant growth, and yield. These findings highlight the potential benefits of incorporating these fertilizers in sorghum cultivation, contributing to improved agricultural practices and increased crop productivity.
