Abstract

A field experiment was conducted at Agro Climate Research centre (ACRC), Agricultural Research Institute (ARI), Rajendranagar, Professor Jayashankar Telangana State Agricultural University (PJTSAU), Hyderabad to investigate the impact of different dates of sowing and varieties on the growth parameters of groundnut crop during the rabi season 2022-2023. The experiment was laid out in split plot design with main plots three sowing dates: D1 -22nd October, 2022, D2 - 7th November, 2022, and D3 - 22nd November, 2022 and five subplots with five varieties: V1– TMV-13, V2– VRI-10, V3– DH-256, V4– GJG-33, and V5– K-6 and replicated three times. The results revealed that the plant height at physiological maturity of groundnut was significantly higher in the crop sown on 22nd November, 2022 (44.7 cm) than that of crop sown on 22nd October, 2022 (39.7 cm) and 7th November, 2022 (41.3 cm). However, dates of sowing had no significant influence on leaf area of groundnut cropat physiological maturity. Drymatter production at physiological maturity was significantly higher in crop sown on22nd Oct, 2022 (6267 kg ha-1) than that of crop sown on7th Nov, 2022 (5800kg ha-1) and 22nd Nov, 2022 (5395kg ha-1). Among the varieties, plant height at physiological maturity significantly higher in variety K-6 than that of VRI-10, DH-256 and GJG-33 but on par with TMV-13. However, leaf area (cm2 plant-1) at harvest was significantly higher in theK-6 (1456.2 cm2 plant-1) than that of TMV -13 (1045.9 cm2 plant-1) and GJG-33(1203.4 cm2 plant-1) but on par with VRI-10 (1256.2 cm2 plant-1) and DH-256 (1230.4 cm2 plant-1) and for drymatter production (kg ha-1) at physiological maturity was significantly higher in variety DH-256 (6043 kg ha-1) than that of TMV-13 (5778 kg ha-1), VRI-10 (5606kg ha-1) and GJG-33 (5725 kg ha-1) but on par with K-6 variety (5952 kg ha-1).

Conclusion

Based on response of groundnut to different sowing dates and varieties in respect to growth parameter, The following conclusions can be drawn. Among the sowing dates the plant height at harvest of groundnut was significantly higher in the crop sown on 22nd November, 2022 (44.7 cm) than that of on 22nd October, 2022 (39.7 cm) and 7th November, 2022 (41.3 cm). However, dates of sowing had no significant influence on leaf area of groundnut cropat harvest and drymatter production at harvest was significantly higher on 22nd Oct, 2022 (8890 kg ha-1) than that of crop sown on 22nd Nov, 2022 (7044 kg ha-1) and 7th Nov, 2022 (8278 kg ha-1). Among the varieties, plant height at harvest was significantly higher in K-6 (46.4 cm) than that of VRI-10 (42.2 cm), GJG-33 (37.2 cm) and DH-256 (39.7 cm) which is on par with the TMV-13 (44.1cm). However, lowest plant height was recorded with variety GJG-33 (37.2 cm) but on par with the DH-256 (39.7 cm). However, leaf area (cm2 plant-1) at harvest was significantly higher in theK-6 (1456.2 cm2 plant-1) than that of TMV -13 (1045.9 cm2 plant-1) and GJG-33(1203.4 cm2 plant-1) but on par with VRI-10 (1256.2 cm2 plant-1) and DH-256 (1230.4 cm2 plant-1) and drymatter production (kg ha-1) at harvest were significantly higher in variety DH-256 (8639 kg ha-1) than that of TMV-13 (7581 kg ha-1) and GJG-33 (7522 kg ha-1) but on par with. VRI-10 (8210kg ha-1) and K-6 variety (8400 kg ha-1).
