Effect of Irrigation and Nutrient Management Studieson Sesame (Sesamum indicum L.)

Abstract

Aim: To study the effect of Irrigation and nutrient management studieson Sesame (Sesamum indicum L.) in red and laterite soil of Odisha. Study Design: Treatments included three irrigation levels (I1: 2 irrigations at 21 and 63 days after sowing, I2: 2 irrigations at 21 and 42 days after sowing and I3: 3 irrigations at 21, 42 and 63 days after sowing ) are treated in main plot and four nutrient management (N1: 100% RDF, N2: 100% RDF + 2 t/ha FYM, N3: 100% RDF + 2 t/ha FYM + Jeevamrut @250 l/ha and N4: 75% RDF + 2 t/ha FYM + Jeevamrut @250 l/ha) are treated in sub plot were experimented in split plot design replicate thrice. Place and Duration of Study: A field experiment was conducted during Summer at khujimahal, Chandaka, Faculty of Agricultural Sciences, Siksha ‘O’ Anusandhan (Deemed to be University), Bhubaneswar Odisha. Results: The results showed that highest seed yield (643.49 kg ha-1), haulm yield (1820.13 kg ha-1) and harvest index (26.04%) was obtained in I3. N4 (75% RDF + 2 t/ha FYM + Jeevamrut @250 l/ha) showed second highest seed yield (652.21 kg ha-1), haulm yield (1882.07 kg ha-1) and harvest index (25.74%) which is at per with N3. Highest water use efficiency (2.72 kg ha-1 m-1) was calculated in I2N3. Conclusion: cultivation of sesame under75% RDF + 2 t/ha FYM + Jeevamrut @250 l/ha with 2 irrigations at 21 and 42 days after sowing proved better in terms of yield, economics and water use efficiency.
