Abstract:
A field experiment was carried out at College Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand during the summer season 2021. The soil of the experimental unit was loamy sand in texture (locally called as “Goradu” soil) with low in available nitrogen (203 kg/ha), medium in available phosphorus (30.68 kg/ha) and high in available potash (274 kg/ha) with pH 8.05. The experiment was laid out in Randomized Block Design with four replications and ten treatments. The treatments which are T₁: RDF @ 25-50-00 NPK kg/ha (Control), T₂: Rhizobium @ 5.0 ml/kg seed treatment and 1.0 L/ha soil application at first and fourth irrigation, T₃:100% N through FYM, T₄:100% N through vermicompost, T₅:100% N through castor cake, T₆: 100% N through poultry manure, T₇: 50% N through FYM + Seed treatment of Rhizobium), T₈: 50% N through vermicompost + Seed treatment of Rhizobium, T₉: 50% N through castor cake + Seed treatment of Rhizobium and T₁₀: 50% N through poultry manure + Seed treatment of Rhizobium used. The results of the experiments revealed that different organic sources treatments failed to create a significant difference in plant population per meter row length at 15 DAS and at harvest as well as plant height at 30 and 60 DAS of groundnut. The results showed that application of 50% N through poultry manure + Seed treatment of Rhizobium was recorded significantly higher plant height (55.48 cm) at harvest, number of pods per plant (28.13), pod yield (2986 kg/ha) and haulm yield (4636 kg/ha) whereas higher dry weight of nodules (80.91 mg/plant) at 50 DAS was recorded with 50% N through vermicompost + Seed treatment of Rhizobium. Significantly higher protein content of kernel (24.33%) and nitrogen content in kernel (3.89%) and haulm (2.09%) observed under application of 50% N through castor cake + Seed treatment of Rhizobium. However, higher net realization (₹107918/ha) and benefit cost ratio (3.61) were obtained with application of 50% N through poultry manure + Seed treatment of Rhizobium (T₁₀) as compared to other treatments.
