Field experiments were conducted to studies the interaction effect of sulphur, magnesium and acephate on growth parameters, yield components and yield of mustard during rabi season of 2022-23 and 2023-24 at students instructional farm, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur under Central Plain Zone of Uttar Pradesh. The experiment consist of 18 treatments combinations in factorial randomized block design with three replications consisted of three levels of sulphur (0, 20 and 40 kg ha-1), three magnesium levels (0, 10 and 20 kg ha-1) and two pesticide levels (with acephate and without acephate). The results demonstrated significant improvements in growth parameters with the combined treatments, notably increasing plant height to 183.25 cm at 60 days after sowing. While plant population remained constant at 13.44 plants per square meter, dry matter accumulation rose from 27.13 g to 28.22 g per plant, and branching increased from 12.59 to 13.14 branches per plant. The S and Mg treatments synergistically enhanced leaf development, with the highest leaf counts observed in the S x Mg treatment. Yield attributes, including the number of siliques per plant and seeds per silique, were significantly improved, particularly with the S x Mg and S x Mg x I interactions. Seed production and stover yield were also notably increased, emphasizing the importance of integrated nutrient and pest management for optimizing mustard production.

A field experiment was conducted at Crop Research Center, Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut, Uttar Pradesh, with compare the production potential under different crop establishment methods and nutrient management and also to find out the economic viability of this cultivar for soil quality. The treatments comprised of Main Plot Puddled Transplanted Rice (C1), Un-puddled Transplanted Rice (C2) and Raised-Bed Planting (C3) Sub Plot Control (N1), 100% NPK (150: 75:60) (N2), 50% RDN + FYM @15ton ha-1 (N3), 50% RDN + vermicompost @ 5ton ha-1 (N4), 50% RDN + FYM @15 ton ha-1 + Bio-stumulant G @ 20Kg ha-1 (N5) and 50% RDN + vermicompost @ 5 ton ha-1 + Bio-stumulant G @ 20Kg ha-1 (N6). revealed that crop establishment methods treatment C1 (Puddled Transplanted Rice) and Nutrient management N6 (50% RDN + vermicompost @ 5ton ha-1 + Bio-stumulant G @ 20Kg ha-1) exhibited significant influence on yield attributes and yields of rice as compared to the application of Un-Puddled Transplanted Rice and control treatment.

A field experiments was carried out during 2018-19 and 2019-20 at Agronomy Research Farm, CCS HAU, Hisar. To compute the temperature based agrometeorological indices for Indian mustard sown under different growing environments along with Split plot design. Two sowing environments imposed through different sowing dates (2nd week of November and 4th week of November) and two irrigation levels (One irrigation at flowering stage and No post-sown irrigation) in main plots and four fertilizer levels (87.5%, 100%, 112.5% and 125% RDF) in subplots and replicated thrice. Crop sown during 2nd week of November had significantly higher agrometeorological indices (GDD, HTU, Tphoto, Tnycto and TIDR) values over 4th week of November sowing. Among irrigation levels, one irrigation performed better with respect to agrometeorological indices. Among fertilizer levels, application of 125% RDF exhibited significantly higher agrometeorological indices followed by 112.5%, 100% and 87.5% RDF. The seed yield and biological yield were highly significantly co-related with the accumulated GDD (0.95** and 0.95**), HTU (**0.83 and 0.83**) Tphoto (**0.96 and 0.96**), Tnycto (**0.953 and 0.951**) and TIDR (0.970** and 0.970**) clearly suggesting thereby the significant effect of these indices on the mustard crop. These indices can therefore very well used as indicators of crop performance, once these relationships are quantified and tested.

The present investigation was undertaken to study of chemical properties of Daurala block Soil (district Meerut) under maize-potato sugarcane cropping system. The depth wise soils samples in maize-potato sugarcane cropping system at five different locations were analyzed for pH, EC, organic carbon, total nitrogen, macro and micronutrients. The surface and sub surface soil were in neutral to alkaline and none of the soil was found to be saline category. The organic matter content declined with soil depth, varied from 0.20 to 1.01 % at surface and sub surface soil. The available N, P and K 161 to 220, 8.1 to 42.9 and 144 to 379 kg ha at surface and sub surface soil and declined with increasing soil depth. Among the different micronutrients with exception of zinc and Fe, the availability of Cu and Mn micronutrients were in sufficient range. The availability of these micronutrients declined with increase in soil depth.
