Abstract

The field experiment was conducted on loamy sand soil of medium nitrogen, medium phosphorus and high potassium content with pH 8.1 at Research Farm, ICAR-AICRP on Pearl Millet, Agricultural Research Station, Mandor, Agriculture University, Jodhpur during Kharif 2022 in randomized block design with four replications. The treatments comprised of 50% RDN in two split doses as urea top dressing at 25-30 and 35- 40 DAS (T1), 25% RDN as urea top dressing (25-30 DAS) + two foliar spray of nano urea (2 ml l-1 of water) at 35-40 and 45-50 DAS (T2), Two foliar spray of nano urea (2 ml l-1 of water) at 35-40 and 45-50 DAS (T3), 25% RDN as urea top dressing (25-30 DAS) + two foliar spray of water (600 litre ha-1) at 35-40 and 45-50 DAS (T4) and Two foliar spray of water (600 litre ha-1) at 35-40 and 45-50 DAS (T5). Results revealed that effective tillers plant-1 (1.7), grain yield (3793 kg ha-1), fodder yield (7578 kg ha-1), gross return (111868 Rs.ha-1), net return (80829 Rs ha-1) and BC ratio (5.3) were recorded higher under 50% RDN given as urea top dressing (T1) being at par with 25% RDN given as urea top dressing + two foliar spray of nano urea (2 ml l-1 of water) at 35-40 and 45-50 DAS (T2).
