GROWTH AND YIELD OF KOHLRABI AS INFLUENCED BY NITROGEN AND POTASSIUM

Abstract

The present study was undertaken with the aims to investigate the effect of nitrogen and potassium which influence the growth and yield of kohlrabi in the field condition. The experiment was conducted during the period from November 2017 to January 2018 at Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka. The experiment was performed with Randomized Complete Block Design which consists of two factors viz., four levels of nitrogen fertilizers; N : Control, N 1 :100Kg/ha, N 2 :120kg/ha, N :140kg/ha and three levels of potassium fertilizers viz., k 0 : Control, K 1 3 :100kg/ha, K :120kg/ha. The results indicate that the morphological parameters and the reproductive components, as well as yield were influenced significantly among the treatments. The highest plant height (35.75cm), number of leaves plant -1 2 (10.33), knob length (7.38 cm), knob diameter (5.00 cm), weight of knob (168.66 g), dry matter content of knob (7.16 %), yield per hectare (16.06 t/ha) were obtained from treatment combination N 3 K while the lowest was recorded from N 0 K 0 1 . Hence it can be concluded that 140 kg/ha nitrogen and 100 kg/ha potassium gave the better growth and yield performances of kohlrabi.
