Abstract
Studies on the “Effect of nutrient management on cutting production, storage and
rooting of carnation (Dianthus caryophyllusL.)” were carried out at the experimental farm of
the Department of Floriculture and Landscaping, Dr.Yashwant Singh Parmar University of
Horticulture and Forestry, Nauni, Solan during 2010-12 on commercial carnation culitvars
viz.; ‘White Wedding’, ‘Farida’, ‘Niva’ and ‘Madras’. The studies included two experiments.
First experiment was conducted during 2010-11 on the effect of nutrient management on
cutting production of carnation. The second experiment was carried out during 2011-12 to see
the effect of storage on rooting of carnation cuttings using best nutrient management
treatment obtained from first experiment applied for cutting production. One week before
planting, full dose of phosphorous and potassium and half dose of nitrogen were incorporated
into the beds according to the treatment requirements and the remaining half dose of nitrogen
was applied at the time of planting. Besides the application of basal dose of N, P and K,
different doses of N and K were also applied through fertigation which was given twice a
week. Application of biofertilizers (VAM, Azospirillum and PSM) @ 3 g/plant and
vermicompost @ 1 kg/m

was done ten days after planting. Findings of the first experiment
revealed that fertilizer module FM

NPK as basal application
along with 200 ppm N + 280 ppm K as fertigation given twice a week resulted in the
production of cuttings with maximum diameter (0.75 cm), weight (5.22 g), number of
cuttings per plant per harvest (4.25), total numberof cuttings (16.98), yield of cuttings per
metre square (152.78) and cost benefit ratio (1:1.95). Results of the second experiment
revealed that cuttings stored for 7 days resulted in minimum percentage of weight loss (3.48
%) and maximum cost benefit ratio (1:3.55). Cuttings that were stored for 7 days (S
1
) and 14
days (S
2
) resulted in 100 per cent rooting. The studies also indicated that carnation cuttings
can be stored up to 35 days at 2°C without significant change in quality and quantity of
cuttings.
