Performance of pigeonpea genotypes under transplanting technique

Abstract

A field experiment was conducted for the yield maximization in pigeonpea through transplanting technique underdryland conditions in medium black soils at Regional Agricultural Research Station, Vijayapura (Karnataka) during kharif2021-22. The experiment was laid out in split plot design with three replications. There were ten treatment combinations,consisting two varieties viz.,TS-3R and GRG-152 in main plots and five dates of transplanting viz., direct sowing, IIFortnight (FN) of June, I FN of July, II FN of July and I FN of August in sub plots. The results revealed that thevariety TS-3R transplanted during II FN of June recorded significantly higher total dry matter production (230.90 g plant-1), leaf area(82.88 dm2 plant-1),pods per plant (184.17), grain yield (1873 kg ha-1), stalk yield (5001 kg ha-1) and gross returns(`118004 ha-1) over other combinations. However, direct sown TS-3R recorded significantly higher net returns(`78231 ha-1) and B:C (3.38) as compared to other combinations. While, lower total dry matter production (121.72 g plant-1),leaf area per plant (38.22 dm2), lower number of pods per plant (92.25), grain yield (876 kg ha-1), stalk yield (2665 kg ha-1), netreturns(`9654 ha-1) and B:C ratio (1.21) were recorded in GRG-152 transplanted during I FN of August compared to otherinteractions. Pigeonpea variety TS-3R transplanted during II FN of June produced superior growth, yield parameters andseed yield. However, the yield improvement was not substantial to overcome the additional costs involved in nurseryraising and transplanting.
