Abstract
An experiment was conducted during kharifseason of the years 2021 to 2023 (Three years) at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar having loamy sand soil to study the Nitrogen management in kharif pearlmillet. The experiment was laid out in randomized block design and replicated four times with seven treatments. On three years pooled results application of 80 kg N/ha being at par with 75% RDN as chemical fertilizer in addition with 25% RDN through castor cake or vermicompost or FYM recorded significantly higher plant height at 60 DAS, at harvest, length of earhead over rest of treatments. Further, it also significantly increased seed yield (1631 kg/ha) and stover yield (3754 kg/ha). Maximum net realization and benifit : cost ratio (BCR) were registered with application of 80 kg N/ha as chemical fertilizer followed by 75 % RDN as chemical fertilizer + 25 % RDN through castor cake in pooled results. Higher yield and net realization can be secured with the application of either 100% RDN (Recommended Dose of Nitrogen) i.e. 80 kg/ha through chemical fertilizer + 25 % RDN through castor cake or vermicompost (20 kg N/ha) in addtion to recommend dose of phosphourus 40 kg/ha as basal under North Gujarat Agro climatic conditions.
