Abstract
ABSTRACT
The present investigation entitled “Effect of NPK levels on growth and yield of China
aster (Callistephus chinensis L. Nees) cv. Kamini” was conducted at the research farm of the
Department of Soil Science and Water Management, Nauni, Solan during the year 2017 and
2018 with seven treatments comprising of T1 – without fertilizers application – (Control),
T2 – 25% recommended dose of NPK, T3 – 50% recommended dose of NPK, T4 – 75%
recommended dose of NPK, T5 – 100% recommended dose of NPK and T6 – 125%
recommended dose of NPK and T7 -150% recommended dose of NPK with four replications
in a randomized block design. The study was executed to investigate the effect of different N,
P and K levels on growth and yield of China aster. Conjoint use of different N, P and K levels
significantly increased the soil nutrient status, growth and yield attributes of China aster crop.
Treatment T7 recorded maximum soil available nitrogen, phosphorus and potassium content.
Fresh weight of individual flower (6.08 g), flower diameter (7.54 cm), number of flowers per
plant (36.51) and flower yield (15.96 t ha-1) was found maximum under treatment T7. Also,
treatment T7 recorded highest dry matter yield of plant parts, nutrient contents and uptake of
N (164.88 kg ha-1), P (24.56 kg ha-1) and K (75.74 kg ha-1, respectively). Whereas, the
minimum values for these parameters was found under treatment (T1) where no fertilizers
were applied.
