A field experiment was conducted at the AICRP on Management of Saline Water and Associated Salinization in Agriculture, RVSKVV, College of Agriculture, Indore, at Salinity Research Farm, Baphalgaon, Barwaha, District Khargone (M.P.), to evaluate the effects of gypsum and Gliricidia sepium green leaf biomass on the growth and yield of wheat under sodic Vertisols. The experiment was laid out in a split-plot design with three replications and comprised three levels of gypsum requirement (0, 50 and 75% GR) and three levels of Gliricidia biomass (0, 5 and 10 t ha-1). The results showed that increasing levels of gypsum and Gliricidia significantly improved plant population, plant height, number of tillers, dry matter accumulation, yield attributes, and wheat yield. The 75% GR treatment recorded the highest plant population (130.0 m-2), plant height at harvest (89.1 cm), tillers per plant (6.60), dry matter accumulation (22.73 g plant-1), grain spikes (19.8 plant-1), test weight (24.02 g), grain yield (3878.3 kg ha-1), straw yield (5150.0 kg ha-1), and biological yield (9028.3 kg ha-1). Similarly, the application of 10 t ha-1 Gliricidia produced superior growth and yield parameters. The combined use of gypsum and Gliricidia was effective in improving wheat productivity under sodic soil conditions. The study indicates that the integrated application of 75% gypsum requirement together with 10 t ha-1 Gliricidia biomass is a promising strategy for sustainable wheat production in sodic Vertisols of the Nimar Valley.

A field experiment was conducted during the Rabi season of 2025–26 at the AICRP on Dryland Agriculture Research Farm, College of Agriculture, Indore, Madhya Pradesh, India, to evaluate the influence of organic manures and inorganic Fertilizers on the physico-chemical properties of Vertisols under chickpea (Cicer arietinum L.) cultivation. The experiment comprised nine treatments involving different levels of inorganic Fertilizers, farmyard manure (FYM), crop residues and their combinations, arranged in a randomised complete block design (RCBD) with three replications. The integrated application of FYM (6 t ha⁻¹) with N₂₀P₁₃ (T₆) significantly improved soil quality compared with the sole inorganic Fertilizer treatments and the control. This treatment recorded the highest soil organic carbon (0.79%), available nitrogen (318 kg ha⁻¹), available phosphorus (16.2 kg ha⁻¹), available potassium (730 kg ha⁻¹) and available sulphur (19.3 mg kg⁻¹). Organic manure treatments also reduced soil bulk density and enhanced water-holding capacity while maintaining soil pH and electrical conductivity within acceptable limits. Furthermore, integrated nutrient management increased the availability of DTPA-extractable micronutrients (Fe, Zn, Cu and Mn) and improved chickpea growth and productivity. The results indicate that combining organic manures with inorganic Fertilizers improved soil physico-chemical properties, nutrient availability and soil fertility under the experimental conditions. Integrated nutrient management may therefore be an effective strategy for maintaining soil health and improving crop productivity in Vertisols.
