Description A field experiment was conducted during Kharif season 2009 at Main Agricultural
Research Station. University of Agricultural Sciences, Dharwad to study the response of
hybrid pigeonpea to planting geometry and fertility levels. The experiment was laid out in
factorial RBD design with three replications. The experiment consisted of nine treatment
combinations of hybrid pigeonpea ICPH- 2671 with two factors, three planting geometry S1-
60 cm x 30 cm, S2 90 cm x 30 cm, S3 90 cm x 45 cm, and three fertility levels F1 25: 50 N, P
Kg ha-1 F2 37.5: 75 N, P kg ha-1 F3 50: 100 N, P kg ha-1 respectively and pigeonpea variety
Maruti (ICP-8863) with recommended packages of practices in control plot. The results
revealed that the hybrid pigeonpea ICPH-2671 recorded significantly higher grain yield
(24.04 q ha-1) and the magnitude of yield increase was 41.7 percent higher as compared to
variety Maruti (16.79 q ha-1). The yield parameters like grain weight per plant, number of
pods per plant, grain yield q ha-1 and growth parameters like number of primary and
secondary branches per plant, leaf area index and dry matter accumulation were higher with
hybrid pigeonpea ICPH-2671 compared to variety Maruti significant difference among the
plant geometry and fertility levels treatment combinations with respect to growth and yield
parameters were observed. The treatment combination S3F3 (90 cm x 45 cm + 50:100 N, P kg
ha-1) recorded significantly higher grain yield (25.65 q ha-1) and it was 42.8 per cent higher
than the control (16.79 q ha-1). The growth and yield parameters were higher with S3F3
treatment combination compared to other treatment combinations. The study indicated that
hybrid pigeonpea ICPH-2671 has better response to wider geometry and higher dosage of
fertilizer help in getting better yields of pigeonpea.
