Impact of Drip Irrigation Regimes and Fertigation Levels on Yield and Economics of Summer Sesame (Sesamum indicum)

A field experiment was conducted at College farm, Water Technology Centre, Professor Jayashankar Telangana State Agriculture University (PJTSAU), Rajendranagar, Hyderabad during 2018 to 2019 study the effect of differential drip irrigation and fertigation schedules on yield economics summer sesame. The framed with ten treatments viz., two levels (0.8 1.0 Epan), (75% 100% recommended dose Nitrogen Potassium), (Equal differential) soil application RDF Drip (1.0 Epan) conventional furrow IW/CPE) were replicated thrice in Randomized Block Design. results revealed that, Potassium (RDNK) through @ 0.8 or Epan either dosages based crop growth stage equal splits recorded significantly superior yields (1011, 971, 977 990 kg/ ha, respectively) compared other treatments. These 13.5 26.7% higher yields, obtained from fertilizer (RDF) (882 kg/ha) a IW/CPE ratio (774 kg/ha). Further, highest water productivity 0.24 kg/m3 RDNK under regime Epan. This treatment also gross returns ( ₹ 96,489 /ha), net (₹ 53,604 /ha) B:C (2.95).
