Abstract
A field experiment was conducted during the rainy (kharif) seasons of 2019 and 2020 at Crop Research Centre of the Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut, Uttar Pradesh, to study the effect of zinc oxide nanoparticles (ZnO-NPs) application on growth and yield of basmati rice (Oryza sativa L.) in alkaline soil. The experiment consisted of 9 treatments, replicated thrice in randomized block design using rice variety ‘Pusa Basmati 1509’. The foliar application of ZnO-NPs increased the plant height by 17.9% at harvesting, number of tillers by 37.3%, dry-matter production by 15.1% and leaf-area index by 69.4% over soil application at 90 days after transplanting (DAT). Grain and straw yield also increased by 16.9% and 17.3%, respectively, compared with conventional fertilization of ZnSO4. Further, the foliar application of ZnO-NPs at the panicle and flowering stage was more effective with respect to the biological yield of rice and increased by 17.0% at harvesting stage. Hence foliar application of ZnO-NPs could be preferred for Zn fertilization in rice production than conventionally soil-applied sources.
