Abstract
Rice (Oryza sativa L.) is the most important staple food of the Indian population. The present study was conducted at Agronomy Research Farm, Acharya Narendra Deva University of Agriculture and Technology, Kumar Ganj, Ayodhya, Uttar Pradesh, on silty loam soil during 2023-24 and 2024-25 to study the productivity of rice. Two-year field experimentation was carried out under a split-plot design grown under Four planting geometries in main plots, viz. 20 cm à 10cm, 15 cm à 15 cm, 20 cm à 15 cm and 30 cm à 15 cm and four nutrient management treatment combinations using 100% RDF (150:60:60), 100% RDF (150:60:60) + micronutrients mixture@0.5% (foliar spray at 30 DAT and 60 DAT), 100% RDF (150:60:60) + Bluegreenalgae@10kg ha-1, and 100% RDF+Jeevamrut@10% (foliar spray at 30 DAT and 60 DAT) in subplots with three replications on crop growth and Quality parameters of rice. Careful observation from the growth indices confirmed that in the main plot, 20 cm à 10 cm, and in the sub-plot, 100% RDF + 0.5% foliar spray of micronutrients recorded significantly the highest in terms of plant height (cm), number of tillers, and Quality parameters of rice. Characters such as hulling %, protein content in grain and protein yield. Hulling % and protein yield (kg ha-1) was also confirmed to have been found highest, respectively.
