Greater Growth and Yield Response of Nano Urea with Conventional Urea for Potato (Solanum tuberosum) Cultivation

In today’s world, adopting new technology is essential to sustain future production. Nanotechnology is becoming increasingly popular due to its efficiency in various scientific applications. In agriculture, nanomaterials significantly enhance the effectiveness of fertilizers and pesticides. Nano fertilizers, in particular, require very small quantities and leave negligible residues, making them environmentally friendly. With this in mind, an experimental trial was conducted during the winter (Rabi) season of 2023-2024 at the Department of Soil Science, HSTU, Dinajpur. The trial used a randomized complete block design (RCBD) with 7 treatments and three replications, focusing on nano-urea i.e., T1 = Control, T2 =100% RDF, T3 = Only Nano urea (3 sprays), T4 = Nano urea (3 sprays) + rest all (no urea), T5 = 50% urea + Nano urea (3 sprays) + rest all, T6 = No urea + no Nano + rest all and T7 = Only urea, respectively. The results revealed that most of the growth parameter with tuber yield was achieved highest in treatment T5, which involved 50% urea combined with nano-urea (3 sprays) and all other standard practices, followed by treatment T2 with 100% recommended doses of fertilizers (RDF). Nano-urea showed promising results in terms of dry matter percentage, chlorophyll content, % protein, and starch levels. It proved to be economically viable by reducing the use of chemical fertilizers by 50%, controlling nutrient release from the soil, providing crops with precise nutrient amounts, increasing yield, and maintaining environmental safety through improved nutrient use efficiency.
