A field experiment was conducted during the
Kharif 2024 season at the Research Farm, Department of Agriculture, Suresh Gyan Vihar University, Jaipur (Rajasthan) on loamy sand soil to study the "Effect of tillage and nutrient management on groundnut (
Arachis hypogaea L.)". Among tillage practices, conventional tillage recorded the highest number of pods per plant (28.06), which was significantly superior to moderate tillage (23.96) and statistically at par with deep tillage (26.96). Conventional tillage also resulted in the highest pod yield, haulm yield, and biological yield, which were comparable to deep tillage and significantly higher than moderate tillage. The maximum net returns (Rs. 1,70,625 ha⁻¹) were obtained under conventional tillage, followed by deep tillage (Rs. 1,60,137 ha⁻¹), with the lowest returns under moderate tillage (Rs. 1,33,373 ha⁻¹).
Regarding nutrient management, the highest number of pods per plant and seed index were observed with the application of 75% RDF + 2.5 t/ha vermicompost (VC) + PSB, which was statistically at par with 50% RDF + 2.5 t/ha VC + PSB. However, the number of kernels per pod and test weight were not significantly influenced by different nutrient management treatments. The maximum pod yield, haulm yield, and biological yield were recorded under the treatment 75% RDF + 2.5 t/ha VC + PSB, which was statistically at par with 50% RDF + 2.5 t/ha VC + PSB. This treatment also led to significantly higher net returns compared to the other nutrient management practices, including control, 100% RDF, and 75% RDF + 2.5 t/ha VC alone.
