Abstract

A field experiment was conducted at Punjab Agricultural University, Ludhiana (Punjab) during kharif 2015 to study the effect of five row spacings (45, 50, 60, 75 and 90 cm) on growth and yield of two pigeonpea genotypes viz., AL 15 (Determinate) and PAU 881 (Indeterminate). The objective of the study was to investigate the performance of pigeonpea (Cajanus cajan L.) under different row spacings and genotypes. The experiment was laid out in randomized complete block design (Factorial) with four replications. It was observed that performance of wider row spacing (60 cm) performed significantly better as compared to other row spacing treatments. Similarly, AL 15 (Determinate) also performed significantly better than PAU 881 (Indeterminate) in all the growth parameters and yield. The wider row spacing i. e. 60 cm (14.92 q/ha) and AL 15 (13.24 q/ha) had significantly higher seed yield than other treatments.
