| 英文摘要 | In contemporary agriculture, sustainability challenges like climate change, declining productivity, and nutrient deficiencies threaten food production. Judicious use of methodologies, dosages, and timing is crucial for sustainable practices. Nano-fertilizers gain importance due to their nutrient-release properties and increased use efficiencies. Chili is a commercial crop that requires high nutrients, the present field trial was carried out at AHRS, Bavikere, Shivmogga (India) during 2020 and 2021, to investigate its growth and yield responses to foliar applications of nano nitrogen (nN) and zinc (nZn) alongside conventional urea and ZnSO4. The experiment comprised combinations of recommended doses of nitrogen (RDN) (75, 100 & 125%) along with two foliar sources, nano (nN & nZn @ 0.4%) and conventional (urea @ 2% & ZnSO4@ 0.2%) against control. Foliar application of nN and nZn @0.4%+125% RDN (T-3) improved growth and yield attributes & green chili yield (33.07 t ha(-1)), compared to RDF (T-1, 23.8 t ha(-1)) and conventional sources (T6, 30.9 t ha(-1)). The utilization of nano-fertilizers in T-3 resulted in a substantial enhancement of 39.0% in yield. Increments of 57.2% and 49.3% in net returns compared to conventional N and zinc sources respectively were also noted. Further, the land productivity reached $13.5 per day in T-3, indicating economic viability. Application of 75% RDN with nN and nZn saved 25-50% of RDN compared to conventional sources. The results propose cutting nitrogen fertilizer by up to 50%, showcasing the eco-friendly aspect of nano-fertilizers. They boost productivity and profitability while supporting sustainable farming by reducing nitrogen usage. |
