Modeling Growth of Cut-Flower Stock (Matthiola incana R. Br.) in Response to Differing in nutrient Level

The present research project was aimed to study the effect of foliar application of zinc and NPK on growth of Stock (Matthiola incana.L. The study was carried out at Floriculture Research Area, University of Agriculture, Faisalabad, during the year 2011-2012. The experiment was laid out in randomized complete block design (RCBD) with three replications. There were twelve treatment combinations comprising four levels of NPK (0, 0.5%, 1% and 1.5%) and three level of Zn (0%,0.5% and 1%,) which were applied on Stock (Matthiola incana.L). The results regarding growth of stock were found significant. The treatments comprising both zinc and NPK as T11 (1% Zn + 1.5% NPK) was ranked first in plant height (91.66 cm), number of leaves per plant (65.33 leaves/plant) and leaf chlorophyll contents (85.53 spade). T7 (0.5% Zn + 1% NPK) was ranked first in leaf area (36.10 cm 2 ) and minimum days to flowering were recorded in T11 (1% Zn + 1.5% NPK), 42.60 days. T11 (1% Zn + 1.5% NPK) got the first position in stalk length (87.63 cm) and floret diameter (4.93 mm). Foliar application of zinc and NPK increased nutrient accumulation in leaves of stock. The nitrogen contents (6.0 %) phosphorus contents (0.46 ppm) and potassium contents (38.10 ppm) increased in response to treatment comprising both zinc and NPK.
