Optimization of Sowing Dates for Grain Amaranth (Amaranthus hypochondriacus L. ) Genotypes in Eastern Dry Zone of Karnataka

摘要

A field experiment was conducted during kharif 2000 at Main Research Station, Univesity of Agricultural Sciences, Bangalore. The experiment consisted of ten treatment combinations involving two genotypes and five sowing dates (June second fortnight toAugust second fortnight) laid out in split plot design. The results revealed that seed yield, number of panicles per plant, 5 ml seed weight, days to 50 per cent flowering and days to physiological maturity were significantly higher at luly first fortnight sowing. However, maximum seed yield of 1301 6 kg /ha was obtained with the interaction effect of Suvarna and luly first fortnight sowing.
