Effect of foliar spray of urea and Nano-urea on the productivity of late-sown irrigated wheat

Experiment Background
Wheat is an important cereal crop of the globe and is sensitive to terminal heat stress imposed at the reproductive stage. Due to climate change, the temperature in February and early March raised which causes heat stress at the reproductive stage (terminal growth phase of a wheat crop) which has become the major causative factor towards low wheat production. In this context, we want to access the effects of wheat productivity by the foliar application of urea fertilizer, and modern Nano Urea fertilizers over the conventional recommended dose of fertilizers. Nitrogen is an essential nutrient for plant growth and is involved in the important synthesis and formation of many important substances and compounds in plants such as amino acids, enzymes, DNA, RNA, and chlorophyll. It is responsible for greenness, vigorous growth, and overall crop development, therefore it must be available for plants in adequate amounts. Nano Urea emerged as a promising alternative for ensuring high crop yield while remaining environmentally friendly. Liquid Nano fertilizer is currently the best alternative to conventional urea fertilizer. The aim of these experiments is to study the effectiveness of Urea, and Nano Urea over conventional urea fertilizers by the foliar application at critical crop growth stages, and try to know the response and fulfills its nitrogen requirement and leads to higher crop productivity and quality in comparison to conventional urea.
