ABSTRACT

A field experiment on the effect of planting dates and pinching on seed production in African marigold cv. Sirakole was carried out during November, 2007 to June, 2008 with four planting dates and three levels of pinching. November planting gave more number of seeds (191.89) and weight of seed per head (0.32g) ,seed yield per plot (272.24 g), 1000 seed weight (1.65g) as well as seed yield (1008.29 kg) per hectare. In addition to these quality traits like germination percentage of seed, root and shoot length of seedlings and vigour index also witnessed significant improvement under this date of planting. Shoot pinching at 30 days after planting was effective in bringing significant improvement in number (173.01) and weight (0.25g) of seeds per head as well as seed yield (309.77 kg) per hectare. Interaction effect of November planting and single pinching improved germination percentage (90.44) and seed vigour index (2098).
