Influence of Different Spacings under Varying Fertility Levels on Protein Content, Protein Yield and Available NPK in Soil of Summer Greengram (Vigna radiata L.)

The present study highlights the influence of different spacings under varying fertility levels on protein content, protein yield and available npk in soil of summer greengram (vigna radiata l.). Due to its importance in Indian agricultural and ability to provide vital amino acids and protein, food beans are a staple of the Indian diet. In the summer of 2020, a field experiment on loamy sand soil was conducted at the Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar. Twelve treatment combinations comprising of four spacings S1 (30 × 10 cm), S2 (30 × 20 cm), S3 (45 × 10 cm) and S4 (45 × 20 cm) and three fertility levels viz., F1 (75% RDF), F2 (100% RDF) and F3 (125% RDF) were evaluated in factorial randomized block design with three replications. The results revealed that significantly higher protein yield (256.10 kg/ha) under 30 × 10 cm spacing as compared to other treatments. Among the fertility levels significantly higher protein content (24.17%), protein yield (260.27 kg/ha) and Higher value of available N and P2O5 status in soil after harvest was observed in treatment (F3) 125% RDF of summer greengram. Thus, from the foregoing results of one year experiment, it can be concluded that for securing higher seed yield, stover yield, protein yield and higher available N, P2O5 in soil after harvest of summer greengram should be sown at 30 cm × 10 cm spacing and fertilized with 100% RDF (20-40-00 N-P2O5-K2O kg/ha) under loamy sand soil.
