Evaluation of INM practices and nano urea on the performance of drum seeded rice

Abstract

A field experiment was conducted on “Evaluation of INM practices and nano urea on the performance of drum seeded rice” at Experiment Farm, Department of Agronomy, Faculty of Agriculture, Annamalai Nagar, Tamil Nadu, India during Late Navarai season (February-May, 2023) in randomized block design with four replications making six treatment combinations. Among different treatments experimented, the treatment T5 - 100% RDF + 25% RDN as goat manure + 0.2% Nano urea spray showed that the maximum highest plant height (98.40 cm), number of tillers m-2 (468.6), leaf area index (5.44), dry matter production (14,216 kg ha-1), grain yield (6,234 kg ha-1) and straw yield (9,261 kg ha-1). Hence, treatment, T5 - 100% RDF + 25% RDN as goat manure + 0.2% Nano urea spray remarkably enhanced the growth and yield of drum seeded rice.
