Abstract
A field experiment was conducted during the Rabi season of 2025–26 at the Agricultural Research Farm of Vivekananda Global University, Jaipur. The experiment consisted of nine treatments arranged in a Randomized Block Design (RBD) with three replications. The treatments included a control (P + K only) along with various combinations of 50% or 100% RDN integrated with single or double foliar sprays of nano-nitrogen at rates of 400 ml ha⁻¹ or 800 ml ha⁻¹ applied at CRI and/or tillering stages. The results indicated that nano-nitrogen application significantly improved growth and yield parameters of barley. Among the treatments, T8 (100% RDN + 800 ml NN ha⁻¹ at CRI + 800 ml NN ha⁻¹ at tillering) produced the highest tiller density (74.20 tillers m⁻¹), plant height (95.72 cm), and dry matter accumulation (131.18 g plant⁻¹). The superior growth performance under T8 translated into improved yield attributes and yield levels. This treatment recorded the highest grain yield (5,509 kg ha⁻¹), biological yield (13,139 kg ha⁻¹), straw yield (7,630 kg ha⁻¹), and harvest index (41.93%). Economic evaluation also demonstrated the advantage of this treatment, with the highest gross return (Rs. 149,056 ha⁻¹), net return (Rs. 97,400 ha⁻¹), and benefit–cost ratio (1.89), despite a slightly higher cost of cultivation. Based on the findings, it can be concluded that foliar application of nano-nitrogen at 800 ml ha⁻¹ at both CRI and tillering stages along with 100% RDN is the most effective approach for enhancing barley productivity and profitability under the semi-arid agro-climatic conditions of Jaipur.
