Abstract
An investigation was carried out on “Standardization of fertigation schedule in
chrysanthemum (Dendranthema grandiflora Tzvelve) var. Marigold under polyhouse
condition” during 2017-18 at Department of Floriculture and Landscape Architecture,
Kittur Rani Channamma College of Horticulture, Arabhavi.
The experiment was laid out in a completely randomized design with nine
different levels of fertigation along with micronutrients with three replications. The
results were analyzed for morphological characters, quality, yield parameters and
economics of chrysanthemum var. Marigold. The results revealed that morphological
parameters like plant height, number of primary branches and plant spread were found
maximum in T7 (75:112.5:75 kg/ha fertigation along with foliar spray of micronutrients)
and significantly differed from other treatments. Whereas leaf area also shown
significant difference which was found highest in T8 (100:150:100 kg/ha fertigation
along with foliar spray of micronutrients).
Parameters which determines earliness in flowering like, days taken for 50
percent flowering, and days taken for first harvest, where found significant in treatment
T7 (75:112.5:75 kg/ha fertigation along with foliar spray of micronutrients). The flower
weight was found highest in treatment T8 (100:150:100 kg/ha fertigation along with
foliar spray of micronutrients).
The quality parameters like, vase life, shelf life, stalk length, flower diameter
were found highest in treatment T7 (75:112.5:75 kg/ha fertigation along with foliar
spray of micronutrients) and found significantly superior to rest of the treatments.
Further, the number of flowers per plant was found highest in T8(100:150:100
kg/ha fertigation along with foliar spray of micronutrients) and also it was found that,
treatment T7 (75:112.5:75 kg/ha fertigation along with foliar spray of micronutrients)
was able to produce maximum flower yield per plant and per hectare with highest
benefit cost ratio.
