Abstract

The fact that radish grows readily and is available for use three to six weeks after planting makes it a favorite crop for kitchen gardens. For encouraging crop development, Trichoderma harzianum is utilized as an active ingredient in a variety of commercially available biofertilizers and biopesticides. The experiment was performed in Horticulture Research Farm, The University of Agriculture Peshawar in the year, 2020. The arrangement of experiment was done in Randomized Complete Block Design (RCBD) with three replicates. Trichoderma harzianum was applied to the radish field before sowing of radish at the concentrations of T1 control (0 kg ha-1), T2 (2 kg ha-1), T3 (4 kg ha-1) and T4 (6 kg ha-1). The different parameters studied were plant height (cm), number of leaves plant-1, leaf length (cm), plant fresh weight (kg), root length (cm), root weight (kg), root diameter (mm), and yield ha-1 (tons). Radish growth and yield were significantly affected by different concentrations of Trichoderma harzianum.  The statistical analysis showed the best results were obtained when the Trichoderma harzianum was applied with the rate of T4 (6 kg ha-1) in all studied parameters. Maximum plant height (68.425 cm), number of leaves plant-1 (15.333), leaf length (40.033 cm), plant fresh weight (0.4283 kg), root length (35.052 cm), root weight (0.2782 kg), root diameter (49.694 mm), and yield tonnes ha-1 (22.803 tons) was recorded with T4 (6 kg ha-1). While minimum results were recorded in T1 (control) in all studied parameters. It is concluded that Trichoderma harzianum should be applied with the rate of 6 kg ha-1 for a satisfactory yield of radish.
