Abstract:
Experiments were conducted during kharif 2018 and 2019 at Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya Raipur (C.G.). The soil of experimental field was clayey (Vertisols) in texture, locally known as “Kanhar” which was low, medium and high in available N, P₂O₅ and K₂O, respectively. The experiment was laid out in randomized block design with three replications and eight treatments. The treatment consisted of maize crop T₁- Drip fertigation with 75% RDF, T₂- Drip fertigation with 100% RDF, T₃- Drip fertigation with 125% RDF, T₄- Drip fertigation with 150% RDF, T₅- Drip fertigation with 175% RDF, T₆- Soil application of 25% RDF and Drip fertigation with 75% RDF, T₇- Soil application with 100% RDF and Drip irrigation, and T₈- No fertilizer and surface irrigation. The total uptake of nitrogen (160.57 kg ha-¹), phosphorus (76.27 kg ha-¹) and potassium (146.41 kg ha-¹) were recorded highest with the treatment of drip fertigation with 175% RDF, Which was significantly superior to others, but it was statistically at par to the treatments of T₃:125% RDF T₄:150% RDF during both the years and on mean basis. However, drip fertigation with 175% RDF found higher protein content in grain, protein yield and production efficiency during both the years and on mean basis.
