A field experiment was conducted at the Instructional Farm, Rajasthan College of Agriculture, MPUAT, Udaipur during two consecutive kharif seasons 2024, 2025 and then after the succeeding crop in rabi 2024-25 and 2025-26, to study the effect of nitrogen and organic nutrient management on growth dynamics of sorghum-chickpea cropping system. An experiment was laid out in split plot design, comprising four nitrogen management practices in main plot treatments (control, 100% recommended dose of nitrogen (RDN), 75% RDN + 25% N through FYM and 50% RDN + 50% N through FYM), five organic sources of nutrients in subplot treatments viz., control, seed treatment with beejamrit (200 ml kg-1 seeds), jeevamrit during each irrigation (500 litre ha-1), ghanjeevamrit as basal application (500 kg ha-1) and vermiwash foliar spray at 30 and 45 DAS (10%), replicated three times. The experimental results showed that application of 100% RDF recorded significantly higher values of growth parameters viz., plant height and dry matter accumulation in sorghum, which was statistically at par with 75% RDN + 25% N through FYM. Whereas, residual effect of 50% RDN + 50% N through FYM recorded significantly higher values of growth parameters, which was statistically comparable with 75% RDN + 25% N through FYM. Among subplot treatments, application of ghanjeevamrit and its residual effect was found to be superior over the rest of the treatments and comparable with application of jeevamrit @ 500 l ha-1 during each irrigation. The results showed that integrated nitrogen management through 50-75% RDN with addition of FYM along with ghanjeevamrit as basal application had positive effect on growth parameters of sorghum-chickpea cropping system.

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 %.

A field experiment entitled “To study the effect of different organic sources on yield attributes and yield of Green gram [Vigna radiata (L). Wilczek]” was conducted on clay-loam soil during Kharif 2025 at the Instructional Farm of Agronomy, Rajasthan College of Agriculture, Udaipur, Rajasthan. The experiment comprised of 10 treatments of different organic sources and seed treatment i.e. control (T1), FYM @ 6 tha-1 + Seed treatment with Beejamrit @ 20 mlkg-1 (T2), FYM @ 6 tha-1+Seed treatment with Rhizobium @ 5 mlkg-1 (T3), FYM @ 6 tha-1 + Seed treatment with NPK Consortium @ 5ml kg-1 (T4), Vermicompost @ 2t ha-1 + Seed treatment with Beejamrit @ 20ml kg-1 (T5), Vermicompost @ 2t ha-1 + Seed treatment with Rhizobium @ 5ml kg-1 (T6), Vermicompost @ 2t ha-1 + Seed treatment with NPK Consortium @5 ml kg-1 (T7), Jeevamrit 1500 L ha-1 at 20 and 45 DAS + Seed treatment with Beejamrit @ 20 ml kg-1 (T8), Jeevamrit 1500 L ha-1at 20 and 45 DAS + Seed treatment with Rhizobium @ 5 ml kg-1 (T9) and Jeevamrit 1500 L ha-1 at 20 and 45 DAS + Seed treatment with NPK Consortium @ 5ml kg-1 (T10), which were replicated three times in randomized block design. The soil at the experimental site was slightly alkali reaction, medium in available nitrogen and available phosphorus and high in potassium. In the experiment data clearly show that’s application of organic sources significantly affect yield attributes, seed and haulm yield. Application of treatment Vermicompost @ 2t ha-1+ Seed treatment with NPK Consortium @5 ml kg-1 (T7) recorded maximum number of pods plant-1 (32.0), number of seeds pod-1 (8.33), test weight (36.0 g), seed (993 kg ha-1), haulm (1583 kg ha-1) and biological yield (2576 kg ha-1).
