Abstract

Maize (Zea mays) is one of the most significant staple food crops in the world, it is a monocotyledonous plant that is a member of the Poaceae family. It is crucial to close the maize yield gap in order to fulfil the demand pressure brought on by a fast-expanding population for food. One of the best methods to bridge the gap between actual and prospective production was to provide an adequate quantity of nutrients at the appropriate time and through the appropriate source. The trial was accomplished during the Kharif season in the year 2022-2023 on the PMH13 Variety of Maize. In this study, eight treatments were used to study their influence on Maize growth and yield. The experimental design followed was a Randomized block design which consists of 8 treatment combinations and was replicated three times. The study revealed that the maize has shown a significant response to nano urea with regard to growth and yield attributes. It had observed that the growth and yield parameters of the maize have shown an increasing trend in all the parameters. The maximum plant height was observed at 197.80 cm in T5 (75% RDN+Nano urea @ 4 ml/l) and the minimum was recorded as 156.67 cm in T1 (Absolute control) respectively. Whereas, maximum grain yield was recorded as 65.23 q/ha in T5 (75% RDN+Nano urea @ 4 ml/l) followed by 63.57q/ha in T4 (75% RDN+Nano urea @ 2 ml/l) and the minimum was obtained as 27.63 q/ha in T1 (Absolute control). This study concluded that the nano urea can be used as a sustainable Agri-input and increased yield.
