Abstract

During the present study, the effects of different Ganga sludge based organic fertilizers were investigated on the growth and yield attributes of carrot (Daucus carota). Six fertilizers Jaivik Prom, Pori Potash, Dharti ka Chaukidar, Jaivik Poshak, Jaivik Khad prepared from treated Ganga sludge were analyzed during the present study using a randomized complete block design (RCBD). A total of six fertilizer treatments and one control in three replications were used to study the effects of fertilizer application on length, Shoot and root biomass, area & number of leaves and root biomass & root diameter. All organic fertilizers showed positive impacts on the growth and yield of carrot crop, the superior performance was observed in the combination of potassium fertilizer and Javik Khad (T6) in various growth parameters. Similarly, T5 (Jaivik Khad) performed well in improving leaf area, fruit weight and total yield per plot. In addition, other treatments also exhibited a notable effect on different plant parameters. These results justified the potential of organic fertilizers in improving the growth and yields of crops in a safer and environmentally friendly way. Moreover, the production of organic fertilizers not only provide safer and environmentally friendly way of Ganga sludge management but providing a best alternative to chemical fertilizers. More research should be carried out on sludge-based organic fertilizers like processing, production and field application at laboratory level and on multiple field crops

Conclusion

The superior performance of the combination of potassium fertilizer and Javik Khad (T6) in various growth parameters of carrot plants can be attributed to the synergistic effects of these two components. Potassium is known to play a crucial role in promoting overall plant growth, improving nutrient uptake, and enhancing stress tolerance. Javik Khad, being an organic NPK source, likely provides a well-balanced blend of essential nutrients, including nitrogen, phosphorus, and potassium, which are vital for plant development. The collaborative action of these nutrients in T6 appears to have positively influenced shoot and root biomass, shoot and root length, leaf area, and root diameter. Additionally, the organic nature of Javik Khad may contribute to improved soil structure and microbial activity, further supporting plant growth. Conversely, treatments with less comprehensive nutrient profiles or those lacking a balanced combination of essential elements may result in suboptimal outcomes for specific parameters. The effectiveness of T5 (Javik Khad with organic NPK) in root-related parameters underscores the importance of organic nutrient sources in promoting robust root development. In contrast, the mixed results observed in T3 (organic fertilizer with neem oil and neem cake) may be attributed to the variable impacts of neem components, with potentially positive effects on shoot biomass and root diameter but less consistent benefits across other parameters
