Abstract

Optimum nutrient management for good yields with reducing cost of cultivation is desirable for cultivation of fodder crops. In order to evaluate the best practice for nitrogen management in fodder bajra with urea and nano urea applications, the present investigation was carried out during rabi 2021 with 6 treatments and 4 replications in randomised block design at College farm, College of Agriculture, Rajendranagar, Hyd-30, Telangana, in sandy loam soils. The study disclosed that urea application @27 kg N/ha each at basal, 20 & 40 DAS (T2) recorded significantly at par with basal urea application @27 kg N/ha + foliar spray of nano urea liquid @2.5 ml/l each at 20 & 40 DAS with respect to fodder bajra growth and yield. 100 % RDN application through urea recorded higher results w.r.t economics over other treatment applications. Hence, N management through urea and also urea + nano urea liquid foliar spray @2.5 ml/l might be the best combination among other foliar spray rates for obtaining best use efficiency and sustainability.

Conclusion

Based on the present analysis, it can be concluded that basal urea application @ 27 kg N/ha & foliar spray of liquid nano urea @ 2.5 ml/l each at 20 and 40 DAS could be the best nitrogen management practice. However, urea application @ 27 kg N/ha each at basal, 20 and 40 DAS as 100% RDN application through urea recorded statistically on par with urea & liquid nano urea foliar sprays @2.5 ml/l each at 20 and 40 DAS w.r.t yield attributes and yield of fodder bajra. 100% RDN application through urea recorded higher returns and B: C ratio over other treatment applications.
