Abstract:
A field experiment was conducted at Agronomy Instructional Farm, Department of Agronomy, C. P. College of Agriculture, S. D. Agricultural University, Sardarkrushinagar to study the effect of organic manures, phosphorus and sulphur on growth, yield attributes and yield of summer groundnut in loamy sand during summer 2020 and 2021. There were eighteen treatment combinations comprising of three organic manures i.e., M₁: 5 t FYM/ha, M₂: 0.75 t castor cake/ha and M₃: 2.5 t vermicompost/ha as well as three levels of phosphorus i.e., P₁: 25 kg P₂O₅/ha, P₂: 50 kg P₂O₅/ha and P₃: 75 kg P₂O₅/ha and two levels of sulphur i.e., S₁: 20 kg S/ha and S₂: 40 kg S/ha were tested in a spilt-split plot design with four replications. The results revealed that an application of 2.5 t vermicompost/ha, 75 kg P₂O₅/ha and 40 kg S/ha either in combination or alone gave significantly higher growth, yield attributes and yield parameters viz., higher number of pods per plant, pods weight per plant, seed index, pod and haulm yield of summer groundnut.
