A field experiment was conducted during the rabi seasons of 2023-24 and 2024-25 to assess the mulching and agro-chemicals on plant population and growth of wheat at the Instructional Farm, Department of Agronomy, Rajasthan College of Agriculture, MPUAT, Udaipur. The experiment was laid out a split-plot design with four mulching levels in main plots (No mulch, 2 t mulch ha-1, 4 t mulch ha-1, 6 t mulch ha-1) and five agro-chemicals treatments in sub-plots (control, KCl 0.2%, CalCl2 , 0.1 %, Salicylic acid 100 ppm, Thiourea 100 ppm) replicated thrice. Results indicated that growth parameters were significantly influenced by mulching levels. 4 t mulch ha-1 recorded the highest plant population growth (15.65), plant height (45.62, 76.66 and 88.91cm) and dry matter accumulation (16.58, 35.41 and 46.36g plant-1). Among agro-chemicals treatment application of salicylic 100 ppm recorded the maximum growth parameters like as plant height (44.50, 70.57 and 82.60 cm) and dry matter accumulation (15.93, 30.97 and 42.81g plant-1) followed by KCl 0.2 % and CaCl2 0.1 %.

Genotype × environment interaction is an important consideration in groundnut improvement because yield and related traits are strongly influenced by environmental conditions. The present study evaluated the stability and adaptability of 74 groundnut genotypes, including four standard checks, across six environments during the Kharif seasons of 2023 and 2024. The environments represented three locations: CTAE Instructional Farm, Udaipur; KVK, Rajsamand; and KVK, Chittorgarh. The experiment was conducted in an augmented block design, and observations were recorded for days to 50 per cent flowering, number of branches per plant, dry pod yield per plant, kernel yield per plant, and 100-seed weight. Stability analysis was performed using the Eberhart and Russell model based on mean performance, regression coefficient, and deviation from regression. Pooled analysis of variance showed significant effects of genotype, environment, and genotype × environment interaction for all studied traits, indicating differential responses of genotypes across environments. Several genotypes showed desirable mean performance and adaptation for yield-related traits. Based on dry pod yield, kernel yield, and associated stability parameters, PI-614, PI-1362, PI-1660, PI-1989, PI-2124, PI-2311, PI-2452, PI-2506, PI-2571, PI-2749, PI-1473, PI-1530, PI-1918, PI-2344, PI-2544, and PI-3132 were identified as promising genotypes. These genotypes may be useful in breeding programmes aimed at improving yield performance and adaptability in groundnut, subject to further validation across additional environments.
