Abstract

A field trial was conducted at Ornamental Horticulture nursery, Department of Horticulture, University of Agriculture, Peshawar in winter 2014 to determine the response of phosphorus levels on growth and yield components of Radish Cultivars,. Randomized Complete Block Design (RCBD) with split plot arrangement was used and there were three replication. Phosphorus levels were allotted to main plot, while cultivars (Nong woo bio, Long red radish, Mino early long white and Green neck) were assigned to sub plots. Results showed that all the growth parameters were statistically different among cultivars as well as phosphorus levels. Green neck cultivar showed maximum root diameter (3.27cm), root weight (232.03g), yield per plot (1.79 kg), and total yield (29.88 tons ha-1), while Long red radish cultivar showed minimum results in root diameter (1.54 cm), root weight (125.11g), yield per plot (0.69 kg) and total yield (21.30 tons ha-1). Regarding phosphorus levels, no of leaves (20.27), fresh leaf weight (116.38 g), root length (26.29 cm) maximum root weight (255.39g), root diameter (3.03cm), yield per plot (3.63 kg) and total yield (29.40 tons ha-1) were recorded at phosphorus level 60 kg ha-1 while minimum no of leaves (16.33), fresh leaf weight (98.13g), root length (20.77 cm) root weight (154.41g), root diameter (2.27cm), yield per plot (2.64 kg) and total yield (23.25 tons ha-1 ) were recorded in control treatment. Maximum Cultivar Green neck supplied with 60 kg ha-1 of P showed better results and hence recommended for radish growers in Peshawar Valley.
