Abstract
A field experiment was conducted during the two consecutive summer seasons of 2021 and 2022 at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar to asses the effect of drip fertigation on growth and quality parameters of summer pearlmillet under North Gujarat condition. There were 18 treatment combinations comprising two irrigation intervals viz., One and Two days interval; three moisture regimes viz., 100, 80 and 60% ETc in the main plot and three levels of N fertigation viz., 100, 80 and 60% RDN in sub-plot were tested in split plot design with three replications. The pooled results of irrigation interval, moisture regime and fertigation practice show that application of irrigation at alternate day under 100% ETc along with 100% RDN through drip fertigation had a significant effect on crop growth, yield and yield contributing characters and quality parameters and their values were significantly higher than other irrigation interval, drip irrigation regimes and fertigation levels. It also uptake significantly higher nitrogen and phosphorus in grain and straw of pearlmillet raised during summer season.
