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 yield, nutrient uptake and economics 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 yields (grain: 2792 kg ha-1 and straw: 7805 kg ha-1) and nutrient uptake of transplanted barnyard millet. This was followed by 20 × 20 cm which was on par with 20 × 10 cm. With regards to NPK levels, application of 150 % RDF (60:45:75 kg NPK ha-1) recorded higher yields (grain: 2830 kg ha-1 and straw: 7899 kg ha-1) and nutrient uptake of transplanted barnyard millet which is on par with 125% RDF (50:37.5:62.5 kg NPK ha-1). Among the treatment combinations, seedlings transplanted at 15 × 15 cm and fertilized with150% RDF (60:45:75 kg NPK ha-1) registered higher values for yields and nutrient uptake of transplanted barnyard millet which was on par with seedling planted at 15 x 15 cm and fertilized with 125 % RDF (50:37.5:62.5 kg NPK ha-1). In economic point of view, seedlings transplanted at 15 × 15 cm and fertilized with 125% RDF (50:37.5:62.5 kg NPK ha-1) recorded higher net return and return rupee-1 invested in transplanted barnyard millet. 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, uptake of nutrients and profitability of transplanted barnyard millet.
