Abstract
An experiment was conducted to study the ‘’Response of zinnia cultivars to boron levels’’ at ornamental Nursery, Department of Horticulture, The University of Agriculture, Peshawar during 2014. The experiment was Completely Randomized Design (CRD) having three replications. There were four boron levels (0 kg ha-1, 1 kg ha-1, 2 kg ha-1, 3 kg ha-1), and three zinnia cultivars (Coral dream, Yellow dream, Pink dream). The result showed that both boron and zinnia cultivars significantly effect in all parameters. Maximum number of flowers plant-1 (18.60), flower diameter (8.71cm), fresh flower weight (9.7g), plant height (40.04 cm), root length (16.3cm) and dry flower weight (1.90g) were observed in plots, supplied with boron at rate of 2kgha-1. Among cultivars Coral dream cultivar showed maximum plant height (35.7cm), flowers number plant-1 (15.04), fresh flower weight (8.5g), flower diameter (8.32cm), root length (13.28cm), and dry flower weight (1.60g). The interaction between boron levels and zinnia cultivars was significant for the observed parameters except plant height. Among different treatments zinnia cultivars, Coral dream and Yellow dream treated with boron 2kg ha-1 should be recommended for maximum growth and flowering attributes under the agro-climatic conditions of Peshawar.

Coral dream cultivar (Table 2) showed the highest plant height (42.00cm) followed with height of (41.2cm) in yellow dream cultivar, while the shortest plant (28.2cm) was noticed in pink dream cultivar, comparison of means show that the coral dream cultivar showed the highest plant height (41.03cm) in plots treated with boron 2 kg ha-1, followed by yellow dream cultivar which gained (40.7cm) plant height at boron 2kg per ha, The lowest plant height (28.2cm) was noted in control plots
During the research period, the response of zinnia cultivars to boron levels was studied
Summary
In the economy of Pakistan agriculture is a Pakistan Zinnia elegans is another glorious flower of dmestic products (GDP) and 45% of labor summer season.it is originated from force is it, while almost 67.5% of Mexico. For 2 kg ha-1, 2512.8 mg of boron have been followed by yellow dream cultivar that taken and dissolved in 1200ml of water and showed (13.83) and lowest number of 10 ml of water have been applied to flower is (13.1) in pink cultivar. Dream cultivar was noted in control plots These findings are in line with [7], who flowers, while the interaction was worked on the effect of boron and zinc on significant between B and Zinnia cultivars the growth and yield of gladiolus.
