Effect of phosphate fertilization, phosphate-solubilizer and plant population on yield and quality of summer groundnut (Arachis hypogaea)

A field experiment was conducted during the summer season of 1994 and 1995 to study the effect of phosphate fertilization, P- solubilizer and plant po pulation on yield and quality of summer groundnut (Arachis hypogaea L.). Th e pod yield was significantly higher under 75 kg P2O5/ha application along with P-solubilizer and with a population density of 0.33 million plants/ha (30 cm x 10 cm). Similarly, higher protein percentage and oil content were also observed with 0.33 million/ha, P-solubilizer and 75 kg P2O5/ha.
