- Abstract
A field experiment was conducted at College of Agriculture, V.C. Farm, Mandya during summer 2020, Rabi 2020 and summer 2021 to study the response of maize to precision water and nitrogen management. The experiment was laid out in strip block design with 21 treatments. Among different levels of irrigations, IW:CPE ratio of 1.0 (I3) recorded significantly higher kernel and stover yield (100.85 and 138.08 q ha-1, respectively) in pooled analysis. Green seeker based N at NDVI 0.8 (N6) recorded significantly higher kernel and stover yield (104.56 and 144.73 q ha-1, respectively). In the interaction, irrigation at IW : CPE ratio 1.0 and Green seeker based N at NDVI 0.8 (I3N3) resulted in significantly higher kernel and stover yield in pooled analysis (114.88 and 166.67 q ha-1, respectively). It was on par with I3N4 i.e., scheduling of drip irrigation at IW : CPE ratio of 1.0 and SPAD based N at threshold 50 (113.18 and 163.95 q ha-1, respectively). Similar trend was observed in all the seasons.
