Abstract
Field experiment was conducted during October, 2020 – January, 2021 at a farmer’s field of Paranjervazhi village, Kangeyam Taluk, Tiruppur District, Tamilnadu, India to study the effect of planting geometry and NPK levels on growth and yield of transplanted barnyard millet. The experiment was laid out in randomized block design with factorial arrangements (FRBD) and replicated thrice. The treatment includes five planting geometry (25 × 10 cm (Recommended line sowing), 15 × 10 cm, 20 × 10 cm, 15 × 15 cm and 20 × 20 cm) and four NPK levels (75 % recommended dose of fertilizer (RDF) (30:22.5:37.5 kg NPK ha-1), 100 % RDF (40:30:50 kg NPK ha-1), 125 % RDF (50:37.5:62.5 kg NPK ha-1) and 150 % RDF (60:45:75 kg NPK ha-1)). Among the planting geometry, 15 × 15 cm recorded higher growth (plant height, number of tillers hill-1, leaf area index, dry matter production), yield attributes (number of earheads hill-1, length of earhead, number of grains per earhead, weight of earhead, test weight) and yields (grain: 2792 kg ha-1 and straw: 7805 kg ha-1) of transplanted barnyard millet. With regards to NPK levels, application of 150 % RDF (60:45:75 kg NPK ha-1) recorded higher growth (plant height, number of tillers hill-1, leaf area index, dry matter production), yield attributes (number of earheads hill-1, length of earhead, number of grains per earhead, weight of earhead, test weight) and yields (grain: 2830 kg ha-1 and straw: 7899 kg ha-1) of transplanted barnyard millet which was on par with 125 % RDF (50:37.5:62.5kg NPK ha-1). Among the treatment combinations, seedlings transplanted at 15 × 15 cm and fertilized with 150 % RDF (60:45:75 kg NPK ha-1) registered its superiority over others and recorded higher values for growth and yield of transplanted barnyard millet which was on par with seedling transplanted at 15 ×15 cm and fertilized with 125 % RDF (50:37.5:62.5 kg NPK ha-1). Therefore, it can be concluded that transplanting of seedlings at 15 × 15 cm and fertilized with 125 % RDF – 50:37.5:62.5 kg NPK ha-1 holds immense potentiality to uplift the productivity of transplanted barnyard millet.
