Abstract

The studies on the long-term effect of the application of organic and chemical sources of nutrients in pearl millet were conducted at a research farm, Department of Soil Science and Agricultural Chemistry, College of Agriculture, Gwalior, (M.P.) during Kharif 2020 and 2021 with nine treatments replicated thrice in RBD. An essential component of crop production is the balanced use of fertilizers. Farmers are using straight chemical fertilizers in an imbalanced manner This imbalanced, excessive use of fertilizers, or the use of purely inorganic fertilizers, has resulted in a negative impact on soil health, fertility and productivity. In order to improve soil health and ecosystem services, the study was conducted to implement strategies that integrate the use of inorganic substances and organic manures, as well as a combination of both. The results indicated that integration of vermicompost @5t ha-1 + 50% RDF resulted in achieving significantly higher grain yield (2779 kg ha-1), straw yield (6921 kg ha-1), harvest index (28.7%) gross return (`92114 ha-1) and net return (`66929 ha-1) of pearl millet on the pooled mean basis in comparison to absolute FYM @20 t ha-1 or vermicompost @10 t ha-1 or 100% RDF alone or their graded combinations. The benefit: cost ratio of pearl millet was recorded at par with the integration of FYM @ 10t ha-1 with 50% RDF, FYM @ 5t ha-1 with 75% RDF, vermicompost @ 5t ha-1 with 50% RDF, vermicompost @ 2.5 t ha-1 with 75% RDF and absolute chemical but they were found significantly higher than the treatments with absolute FYM or Vermicompost or their integration with 25% RDF. This study contributed to the fact that the integration of sources of nutrients gives better results in terms of improving the soil health, soil fertility, biological ecosystem of the soil, which ultimately will increase the production and economics of the crop.

Conclusion

Field experiments were carried out from Kharif 2020 to Kharif 2021 to assess the effect of organic and chemical sources of nutrients and their combinations on the yield and economics of pearl millet in Inceptisols of the Gird region of Madhya Pradesh. The principal findings revealed that the integrated application of vermicompost (@5t/ha with 50% NPK gave significantly higher grain yield, straw yield and harvest index of pearl millet followed by FYM @10 t/ha with 50% NPK. Also, the integrated application of vermicompost (@5t/ha with 50% NPK gave a higher net return and B:C ratio of pearl millet followed by FYM @10 t/ha with 50 % NPK.
