 ABSTRACT

The field experiment was conducted at College farm,Acharya N. G. Ranga Agricultural University (now Professor JayashankarTelangana State Agricultural University), Rajendranagar, Hyderabad during rabi2013-14. The experiment was laid out in split plot with combinations of three moisture regimes viz., 0.6, 0.8 and 1.0 IW/CPE ratios and five phosphogypsum fertilizer levels viz., Pg₁: Control (500 kg ha-1 gypsum at flower initiation), Pg₂: Phosphogypsum @ 250 kg ha-1 at flower initiation, Pg₃: Phosphogypsum @ 250 kg ha-1 (½ as basal and ½ at flower initiation), Pg₄: Phosphogypsum @ 500 kg ha-1 (½ as basal and ½ at flower initiation), Pg5: Phosphogypsum @ 500 kg ha-1 at flower initiation and was replicated thrice. Among moisture regimes highest yield attributes and yield were obtained with I3(1.0 IW/CPE) moisture regime but highest available nutrients in soil after harvest of groundnut were recorded with I1(0.6 IW/CPE) moisture regime. Among phosphogypsum levels highest yield attributes, yield and available nutrients in soil after harvest of groundnut were obtained with Pg5: Phosphogypsum @ 500 kg ha-1 at flower initiation.
