Relationship of SPAD Values with Different Row Spacing of Pearl Millet Grown under Northern Dry Zone of Karnataka

摘要

The effects of row spacing on SPAD values in pearlmillet under dryland conditions were investigated at Northern dry zone (Zone-3) of Karnataka during kharif'of 2013. The experiments consisted of eight planting patterns replicated three times in a randomized block design. At 50% flowering the wider row spacing 120 cm x 5.0 cm gave significantly higher chlorophyll content (60.25) as compared to recommended spacing 60 cm x 10 cm (53.09) and at 20 day's after 50% flowering also the same treatment 120 cmx 5.0cm (50.99) recorded highest SPAD values as compared to recommended spacing 60 cm x 10 cm (42.33) which is at par with the treatments 135 cm x 10cm (49.55), 135 cm x 5.0 cm (49.51). The SPAD values are increased with increase in wider row spacing.
