Effect of varying sowing date and row spacings on yield attributes and yields of rabi grain amaranth (Amaranthus hypochondriacus L.) under South Gujarat conditions.

A field experiment was conducted during winter season of 2005–06 on grain Amaranth (Amaranthus hypochondriacus L.) var. GA-1 to study the response of varying sowing date and row spacings. Among four sowing dates, 1st November was found markedly superior than 15th November, 1st December and 15th December in respect to seed yield and yield attributes viz. Length of Spike, Length of Spikelets and 1,000 Seed Weight along with Benefit: Cost ratio. Whereas, 30 cm row spacing recorded significantly highest seed yield and Benefit: Cost ratio followed by 45 cm row spacing and lowest was associated with 60 cm row spacing, but reverse trend was observed regarding Length of Spike and Spikelets both.
