Abstract

A field experiment was carried out at the farm of Horticulture section, College of Agriculture, Nagpur during the years 2016-17 and 2017-18 in Factorial randomized block design to find out the most suitable dose of nitrogen and phosphorus for increasing seed yield and obtaining better quality seed of China aster with nine treatment combinations and three replications. The treatments comprised of three levels of nitrogen viz., 150, 187.5 and 225 kg ha-1 and three levels of phosphorus viz., 50, 62.5 and 75 kg ha-1. The results revealed that, significantly maximum flowers plant-1, seeds flower-1, germination % of seed, seed yield plant-1 and ha-1 and test weight of seed were registered with the individual treatments of 225 kg nitrogen and 75 kg phosphorus ha-1. However, the treatment combination of 225 kg nitrogen + 62.5 kg phosphorus ha-1 was found to be the best treatment as compared to others for obtaining maximum seed yield and good quality seed in China aster.
