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. |
