A field experiment was conducted during Kharif, 2025 at the Instructional Farm, College of Agriculture, Bhilwara, to study the effect of stress mitigating chemicals and sulphuron growth characters of black gram (Vigna mungo L.). The experiment was laid out in a factorial randomize block design with four stress mitigating chemicals levels viz., control, salicylic acid @ 75ppm (FI) + 7 DAFS, 2 % urea (FI) and thiourea @ 500 ppm (FI) and four sulphur levels viz., control, 10, 20 and 30 kg ha-1, replicated three times. The recommended dose of fertilizer was 20: 40 kg N: P2O5 ha-1 and half nitrogen with full and phosphorus were applied at sowing while the remaining nitrogen was top-dressed in splits.The experimental results showed that application of thiourea @ 500 ppm recorded significantly higher values of growth characters viz., plant height (51.49 cm) and dry matter accumulation (17.84 g plant-1) at harvest in black gram which was superior to lower stress mitigating chemicals levels and was at par with salicylic acid @ 75 ppm (FI) + 7 DAFS. Among the sulphur levels, application of sulphur 30 kg ha-1 recorded significantly higher values of plant height (48.67 cm) and dry matter accumulation (18.06 g plant-1) at harvest which was found superior over control and sulphur 10 kg ha-1 but statistically at par with sulphur 20 kg ha-1. The results indicated that application of thiourea @ 500 ppm in combination with sulphur 30 kg ha-1 had a positive effect on the growth and development of black gram.

The present study was conducted at the Instructional Farm of Rajasthan College of Agriculture, Udaipur, during the kharif seasons of 2024 and 2025 to evaluate the effects of phosphorus-solubilising microorganisms (PSMs) and inorganic phosphorus sources on plant dry matter and yield attributes of maize. The experiment was laid out in a randomised block design comprising 12 treatment combinations with three replications. The recorded attributes included plant dry matter, number of cobs per plant, number of grains per cob and seed index. The combined application of PSMs and inorganic phosphorus sources significantly increased plant dry matter, the number of grains per cob and the seed index compared with the control, whereas the number of cobs per plant was not significantly affected. Enhanced phosphorus availability through microbial inoculants, together with an adequate supply of inorganic phosphorus, promoted root development, nutrient uptake and photosynthetic activity, resulting in improved reproductive growth and grain formation. The highest values for plant dry matter and the significant yield attributes were recorded under the integrated application of PSMs with the recommended dose of phosphorus fertiliser. The findings indicate that integrating phosphorus-solubilising microorganisms with inorganic phosphorus sources can support maize productivity under the conditions of the study. This integrated approach may improve phosphorus availability and the efficiency of phosphorus nutrition while maintaining the measured yield attributes.

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 %.
