Discover the essentials of wheat fertilization with an emphasis on new nano urea technologies, application methods, timing, and optimal nutrient management. This quiz covers key facts to help improve yields and promote sustainable agriculture.
What is the primary purpose of applying fertilizers, such as urea, to wheat crops?
Explanation: The main reason for fertilizing wheat is to provide nutrients, mainly nitrogen, required for healthy growth and higher yield. Fertilization does not directly prevent pests or diseases, nor does it primarily alter soil acidity, and it is not aimed at speeding up seed sprouting.
Compared to traditional granular urea, what is a key advantage of using nano urea on wheat crops?
Explanation: Nano urea is designed for more efficient nutrient delivery, resulting in better absorption. It does not drastically affect water needs, cannot fully replace all other nutrients, and does not directly influence seed germination rates.
What is the recommended method for applying nano urea to wheat crops in the field?
Explanation: Nano urea is typically applied by diluting and spraying it onto leaves, allowing plants to rapidly absorb the nutrients. Burying granules and broadcasting are appropriate for traditional fertilizers, and while fertigation is used for some products, foliar spray is recommended for nano urea.
At which growth stage of wheat is the application of nitrogen fertilizer most beneficial?
Explanation: Nitrogen is most effective when applied during tillering and early stem elongation, supporting vigorous growth. Application after maturity or during storage is ineffective, and pre-sowing nitrogen may be lost before plants can use it.
What is a possible outcome of applying too much nitrogen fertilizer to wheat crops?
Explanation: Overuse of nitrogen can cause wheat plants to become weak and fall (lodging), and can also result in nitrogen runoff, contributing to water pollution. Excess fertilizer does not induce seed dormancy, provide disease immunity, or go without impact.
