International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad T5-19P-1141 Effect of Nano Fertilizers on Growth Yield and Water Use Efficiency of Potato (Solanum tuberosum l.) under Varying Irrigation Schedules Manimala Mahato and Dhananjoy Dutta Department of Agronomy, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal, India 741252 Indiscriminate and over application of irrigation water and chemical fertilizers led to several detrimental effects on crop production system and environment. Therefore, introduction of nano fertilizers as an alternative source of conventional fertilizers has become a new area of research. Besides that, irrational irrigation to water demanding crop, like potato during the post monsoon season affects the growth and productivity. Therefore, a field experiment was delineated with the objective to assess the effect of nano fertilizers on growth, yield and water use efficiency of potato under various irrigation schedules based on cumulative pan evaporation (CPE). Methodology Field experiment was conducted at B.C.K.V. during rabi seasons of 2019-20 and 2020-21 in sandy loam alluvial soil (inceptisol) designed in split plot with three irrigation schedules at I 1- 15 mm, I 2-30 mm and I 3-45 mm of CPE kept as main plot treatments and five nutrient management practices like N1-100% RDF (200:150:150 kg/ha of N: P2O5: K2O), N2-75% RDF+ nano fertilizers (N, P, K at 80:40:40 ppm), N 3-100% RDF+ Nano-Zn (10 ppm), N 4-75% RDF+ nano fertilizers (N, P, K and Zn at 80:40:40:10 ppm) and N5-Nano-fertilizers (N, P, K at 80:40:40 ppm) as subplot treatments replicated thrice. All nano fertilizers were applied as foliar spray at 25 and 50 DAP. Potato (variety Kufri Himalini) was planted in 60 cm ×15 cm spacing during middle of November in 4.8 m × 3 m plot along with other standard package of practices. Results Pooled result reported that irrigation at 15 mm CPE along with 100% RDF and Nano-Zn (10 ppm) (I 1N 3) treatments recorded significantly higher plant height (61.76 cm) at 60 DAP, dry matter accumulation (579.85 g m -2 ) at 90 DAP, tuber no per hill (8.59) and tuber yield (23.04 t ha -1 ). In all cases lower values were obtained from irrigation at 45 mm CPE with nano fertilizers (N, P, K) alone treatment (I 3N 5). However, irrigation at 45 CPE along with 100% RDF and Nano-Zn (10 ppm) (I3N3) treatment recorded higher water use efficiency (9.96 kg m -3 ). 741 | Page Emerging approaches (RS, AI, ML, Drones etc) for crop management &assessment
