Effect of different levels of NPK on growth and yield of China aster [Callistephus chinensis (L.) Nees] var. Poornima

摘要

An experiment was conducted at Met, Thane, Maharashtra to identify the effect of different levels of NPK on growth and yield of China aster var. Poornima. Nitrogen @ 200 kg/ha gave significantly maximum plant height (53.3 cm), number of branches/plant(28.8) and flower yield (115.02 q/ha). Phosphorus @ 100 kg/ha showed significantly maximum plant height (50.27 cm), number of branches/plant (26.66) and flower yield (93.90 q/ha). Similarly, application of potassium @ 25 kg/ha showed significantly maximum plant height (50 cm), number of branches/plant (26.84) but maximum flower yield (91.87 q/ha) was recorded with 50 kg/ha of potassium. Therefore, application of 200 kg N+100 kg P_2O_5+50 kg K_2O and FYM @ 5 t/ha as a basal dose was suggested for increasing the flower yield of China aster var. Poornima.
