A field experiment was conducted at the farm of BTC College of agriculture and research station, Bilaspur, under Agronomy Department, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) in years 2019-20 and 2020-21with a view to study the “Effect of planting geometry and nutrient management on seed yield of kharif pigeonpea (Cajanus cajan L. Millsp.)”. The Pigeonpea variety Rajeevlochan used to grown and treatment was replicated three times in Split plot design. The soil of experimental field was vertisol belonging to textural class clay. In order to prevent the crop from seed and soil born pathogens, seeds were treated with bavistin @ 2.5 g kg-1 seed followed by inoculation with suitable Rhizobium culture @ 5.0 g kg-1 of seed. Then treated seeds were dried in shade for 3- 4 hours before sowing. As per the treatment NPK application were applied separated plot in Pigeonpea with nine treatments in main kharif crop. There were two factors taken in main crop i.e. Main plot: planting geometry (P) viz., P1: 60cm x15cm, P2: 90cm x15 cm, P3: 120cm x15cm and Sub-plot: nutrient management (N) viz., N1: 75% of RDF, N2: 100% of RDF (N:P2O5:K2O :: 20:50:20 kg/ha), N3: 125% of RDF. The yield attributes i.e., Seed yield were significantly superior in the planting geometry P1 (60 cm x15 cm) and nutrient management N3 (125% of RDF). On the basis of above findings, planting geometryP1 (60 cm x15 cm) and nutrient managementN3 (125% of RDF) stand could be better performance first in position and planting geometry P2 (90 cm x 15 cm) and nutrient management N2 (100% RDF) stand in second order of preference. Therefore, it may be concluded that planting geometry P1 (60 cm x15 cm) and nutrient management N3 (125% of RDF) may be prefer for higher yield in pigeonpea.
