Abstract:
A field experiment was conducted at the Instructional Farm, Rajasthan College of Agriculture, MPUAT, Udaipur, during the Kharif season of 2024 to study the effect of vermicompost and ghanjeevamrit on maize (Zea mays L.) growth, yield attributes and productivity. The trial was designed in a factorial randomized block design, with sixteen treatments replicated three times. The treatments involved two factors that is vermicompost and ghanjeevamrit. The experimental soil was clay loam in texture, low in available nitrogen, medium in phosphorus, and high in potassium with adequate levels of DTPA-extractable micronutrients (Zn, Fe, Mn and Cu). The application of 75% RDN by vermicompost led to a significant enhancement in plant height at harvest at 60 DAS (111.57 cm) and at Harvest (218.02 cm), number of cobes plant-1 (1.82), number of grains row-1 at (39.48), number of row cob-1 (14.95), cob length (24.09), seed index (256.73 g), seed yield (3524 kg ha⁻¹) and biological yield (9720 kg ha⁻¹). These values significantly outperformed the absolute control treatment (V0). Similarly in ghanjeevamrit @750kg ha-1 significantly enhancement in plant height at 60 DAS (112.02 cm) and at Harvest (218.99 cm), number of cobes plant-1 (1.82), number of grains row-1 at (39.49), number of row cob-1 (15.39), cob length (24.41), seed index (256.79 g), seed yield (3454 kg ha⁻¹) and biological yield (9639 kg ha⁻¹). These values significantly outperformed the absolute control treatment (G0). The results emphasize the advantage of nutrient synergy in vermicompost and ghanjeevamrit systems, highlighting their potential to enhance crop productivity through sustainable and balanced nutrient inputs.
