Efficient irrigation scheduling and appropriate varietal selection are essential for sustaining wheat productivity under limited water availability. A field experiment was conducted during the Rabi season of 2018–2019 at the Agronomy Research Farm, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya, Uttar Pradesh, to evaluate the influence of irrigation scheduling on the growth and yield of wheat varieties. The experiment comprised 12 treatment combinations involving three irrigation schedules (0.6, 0.9, and 1.2 IW/CPE ratios) and four wheat varieties (HD-2285, NW-1067, Kundan, and Unnat Halna), arranged in a split-plot design with three replications. An irrigation depth of 60 mm was applied at each irrigation. Growth and yield parameters were recorded and statistically analysed. Irrigation scheduling significantly affected wheat growth, yield attributes, and yield. Irrigation at 1.2 IW/CPE produced the highest plant height, dry-matter accumulation (992.60 g m⁻²), leaf area index, tiller density, spike density, spike length, grains per spike, straw yield, and grain yield (42.87 q ha⁻¹). However, its grain yield was statistically comparable with that obtained at 0.9 IW/CPE (41.91 q ha⁻¹), while 0.6 IW/CPE produced 34.73 q ha⁻¹. Among the varieties, HD-2285 recorded the highest grain yield (43.16 q ha⁻¹) and straw yield (58.95 q ha⁻¹), whereas Kundan recorded the lowest grain yield (36.92 q ha⁻¹). The findings indicate that HD-2285 performed best under the experimental conditions and that 0.9 IW/CPE achieved grain yield comparable with 1.2 IW/CPE.

White rust, caused by Albugo candida, is one of the most destructive diseases of Indian mustard, resulting in significant yield and economic losses. The present study was undertaken to evaluate the efficacy of different fungicides for the management of white rust under field conditions. Field experiments were conducted at the Rajasthan Agricultural Research Institute (RARI), Durgapura, Jaipur, during the rabi seasons of 2024–25 and 2025–26. Fungicidal sprays were applied at the onset of disease symptoms, and observations on disease intensity, seed yield, and economic returns were recorded. All fungicidal treatments significantly reduced disease intensity and increased seed yield compared with the untreated control. Among the treatments, Metalaxyl 8% + Mancozeb 64% WP applied at 0.20% proved to be the most effective, recording the lowest disease intensity (13.89% and 15.00% during 2024–25 and 2025–26, respectively), the highest pooled seed yield (14.01 q ha⁻¹), and the maximum incremental cost-benefit ratio (2.85). Kresoxim-methyl 44.3% SC and Kitazin 48% EC were the next most effective fungicides in reducing disease severity and improving seed yield. In contrast, Aureofungin 46.15% SP recorded the highest pooled disease intensity (37.21%) and the lowest disease reduction over the untreated control. The findings demonstrate that Metalaxyl 8% + Mancozeb 64% WP at 0.20% is an effective and economically viable fungicidal option for the management of white rust in Indian mustard under Rajasthan conditions.
