Abstract

Afield experiment was conducted in rainy 2012 and 2013 season to study the effect of two planting dates (early - E, and late - E2), nine spacing combinations and two extra-early genotypes (determinate (DT) ICPL 20338 and non-determinate (NDT). ICPL 20326) on yield and yield contributing traits of pigeonpea. The E, produced higher seed yield in both the DT (892.3 kg/ha) and NDT (1406.2 kg/ha) pigeonpea line. Highest grain yield was recorded with spacing of 30 cm x 20 cm in both the E, (1298.7 kg/ha) and E2 (942.4 kg/ha) of DT line. While in NDT line, spacing of 45 cm x 30 cm in E, (1734.3 kg/ha) and 30 cm x 30 cm in E2 (1511.4 kg/ha) recorded highest grain yield. Planting time showed non-significant effect on flowering and days to maturity in both, DT and NDT lines due to photo-insensitive nature of the extra early lines. These extra-early lines reported to be less affected by varying photoperiods and acceptable yield can be produced throughout the year with modification in the planting geometry. The present study and earlier results of testing these lines at Almora, Uttarakhand and Ludhiana, Punjab provides scope for expanding pigeonpea cultivation and production in wider latitudes/higher altitudes and. into new niches especially in the rice-fallow cropping system.
