The present investigation was conducted to evaluate the influence of organic sources of phosphorus and sulphur on the growth, yield and soil properties of taramira (
Eruca sativa) at Organic Research Farm, Department of Soil Science and Agricultural Chemistry, Institute of Agricultural Sciences, Bundelkhand University, Kargua ji, Jhansi (U.P.) during
Rabi season 2024-25. A field experiment comprising different organic treatment combinations was laid out and observations were recorded on agronomic and soil parameters. Taramira variety RTM-14 (Narendra Tara) was grown in randomized block design and replicated thrice.
Organic nutrient management exerted a significant positive effect on crop growth. Treatments receiving combined organic inputs, particularly T7, produced the tallest plants (119.0 cm), highest chlorophyll content (2.73 mg/m²) and maximum test weight (3.78 g), indicating enhanced vegetative growth and photosynthetic activity. Yield attributes improved considerably under organic management, with T7 recording the highest seed yield (1502.1 kg/ha), stover yield (4587.5 kg/ha) and biological yield (6089.66 kg/ha). Soil physico-chemical properties also improved, as organic amendments lowered soil pH from 8.49 to near-neutral values (6.21-7.04), enhanced organic carbon content (0.57 mg/L C) and improved bulk density and pore space, thereby fostering better soil structure. Nutrient availability was markedly higher under organic inputs, with T7 showing maximum values for available nitrogen (136.48 kg/ha), phosphorus (20.2 kg/ha) and potassium (220.69 kg/ha). Overall, the study concludes that integrated organic sources of phosphorus and sulphur are effective in improving crop productivity& soil sustainability and therefore represent a viable approach for eco-friendly oilseed cultivation.
