A field experiment on next generation technology for nutrient and water management in maize were carried out during kharif 2019-20 and 2020-21 at H-8 Block, GKVK, Bengaluru. Consisting of twelve treatments replicated three times, assigning three levels of irrigation as main plot treatment with four sub plots of nutrient management practices in a split plot design. The results revealed that sensor based drip irrigation at 50 per cent depletion of available soil moisture (DASM) (M_2) along with software based nutrient expert tool (N_1) recorded significantly higher plant height at 30, 60, 90 DAS and at harvest (67.3, 188.9, 206.5 and 220.9 cm, respectively), leaf area at 30, 60, 90 DAS and at harvest (2362, 9105, 12645 and 9020 cm~2 plant~(-1), respectively), SPAD readings at 15,30,45,60,75 DAS (30.6,32.3, 33.2,40.4 and 38.5, respectively) and higher kernel yield (9725 kg ha~(-1)) and stover yield (10352 kg ha~(-1)) on pooled basis compared to sensor based drip irrigation at 75 per cent depletion ofavailable soil moisture (DASM ) (M,) combined with site specific nutrient management (SSNM) (N_2) and also the treatment receiving surface irrigation (M_1) along with recommended dose of fertilizers (N_4) recorded significantly lower plant height (40.1,153.9, 172.2 and 185.6 cm, respectively), leaf area (1633, 5977, 8304 and 5817 cm~2 plant~(-1), respectively), SPAD values (23.2,24.7,25.1,30.6 and 29.2, respectively), lower kernel weight (6916 kg ha~(-1)) and stover yield (7820 kg ha~(-1)).
