Abstract

Rice is a staple cereal grain for millions of the world population. Inorganic, organic and biofertilizer play crucial role in gaining higher production of scented rice. Excessive use of conventional fertilizer lowers the soil heath. Therefore, there is a need for such a technology which will be able to achieve higher sustainable production. Nano urea is a nano technology which can provide a way to bring down the minus of conventional fertilizers. Keeping these in view, present investigation entitled the combined application of inorganic fertilizer and organic manure with Nano urea on growth and yield of scented rice was carried out at Instructional farm unit, Krishi Nagar, JNKVV, Jabalpur during the rainy season of 2022 and 2023. Ten treatments combination was laid out in randomized block design with four replications. The results of present study revealed that application of 75% N through urea + Azospirillum @ 5 kg ha-1 + FS with Nano urea @ 4 ml litre-1 at active tillering (AT) and panicle initiation (PI) stage registered maximum plant height (113.44 and 107.52 cm, respectively), no. of tillers hill-1 (21.88 and 19.49, respectively) during both the years of experimentation. As regard to yield and yield attributes significantly maximum total no. of grains panicle-1 (81 and 78, respectively), panicle length (28.23 and 27.19 cm, respectively), grain (4780 and 4418 kg ha-1, respectively) and straw yield (6652 and 6432 kg ha-1, respectively) was recorded with the application of 75% N through urea + Azospirillum @ 5 kg ha-1 + FS with Nano urea @ 4 ml litre-1 at AT and PI stage during both the years of experimentation. Thus, the study suggests that trimming down the conventional fertilizer by using Nano urea and Azospirillum could help in gaining optimum yield. Also, combination of Nano urea with vermicompost and Azospirillum play important role in improving soil quality alongwith crop health.
