| dc.description.abstract | China aster is one of the most popular winter season annuals. It ranks next to chrysanthemum and marigold. Five colour (pink,light pink,white, creamy white and viotet) are popular among growers. The objective of experiment entitled “Effect of nitrogen and phosphorus on growth, flower yield and vase life of china aster (callistephus chinensis L. Nees)” was to know the nutrient requirement of china aster for growth ,flower yield and vase life. Keeping this in view an experiment was conducted with 4 levels of each nitrogen (N0,N50,N100,N150) and phosphorus (p0,P25,P50,P75) with uniform dose of @ 50Kg-1. Application of 50 Kg N and 75Kg N p ha-1 recorded the maximum plant height of 24.99 and 26.66 cm respectively. 100 kg N and 50KgP2O5 resulted into the maximum plant spread (N-S) of 25.17 and 24.97cm,respectively .N 150 Kg and P 50Kg resulted maximum spread in(E-W) direction. Number of branches per Plant were maximum with N150 and P75 (26.17 and 24.47 respectively). Similarly number of leaves per plant were recorded maximum with application of N100 and P50 (35.40 and 33.92 respectively.) Lower and higher doses of nitrogen did not influence days to flower bud initiation. However, 100 Kg N/ha delayed it . Lower dose of Phosphorus resulted in earlier flower bud initiation. The earliest blooming and harvesting were recorded with lower level of nitrogen and higher level phosphorus. Maximum vase life 6.83 and 6.58 days were recorded with N50 and P25 respectively. Interaction of NxP was found to be non significant for all characters except the fresh weight of flowers .So far as the economics was concerned, the treatment combination N100P75 gave the maximum net profit (Rs 201194ha-1) followed by N150P75(Rs 192458ha-1. | |
