GROWTH AND YIELD OF KOHLRABI AS INFLUENCED BY FERTILIZERS AND MULCHES

Abstract

The field experiment was conducted during the period of November 2016 to January 2017 at Horticulture farm of Sher-e-Bangla Agricultural University Dhaka-1207, Bangladesh. Four levels of organic and inorganic fertilizers viz., F 1 : Recommended doses of NPK (N=125kg/ha, P=60kg/ha, K=110kg/ha), F 3 Recommended dose of poultry manure (11 t/ha), F 4 : ½ recommended doses of NPK+ ½ recommended doses of poultry manure; and three levels of mulches i.e. M 1 : Control, M 2 : White polythene mulch, M 3 : Black polythene mulch were used in the experiment. Result indicated that the vegetative growth of kohlrabi i.e. plants height (cm), number of leaves plant -1 , knob diameter (cm), knob weight with leaves (g), knob weight without leaves (g), root length (cm), and yield plot -1 : Control, F 2 (kg) and yield ha (t ha -1 ) were highest in case of F 4 treatment and M 2 treatment. The combined effect of F 4

M 2 produced the superior result for all vegetative growth and yield of kohlrabi.
