INFLUENCE OF GYPSUM FERTILIZER ON GROWTH AND YIELD OF KOHLRABI

This study was to estimate the influence of gypsum doses on growth and yield of Kohlrabi. The experiment was carried out in the Horticulture Farm, Sher-e-Bangla Agricultural University during January-March, 2021. The experiment was consisted of four treatments: Control (T₀); 100 kg/ha (T₁); 125 kg/ha (T₂); 150 kg/ha (T₃); and the study was following Randomized Complete Block Design (RCBD) with three replications. The vegetative growth and yield contributing parameters of Kohlrabi showed significant variation. The results illustrated that, the higher doses of gypsum fertilizer influenced vegetative growth and yield positively. The highest knob length (5.9 cm), knob diameter (82.3 mm), single knob weight (236.7 g) and yield/plot (11.3 kg) observed in T₃ treatment. Furthermore, application of different doses of gypsum fertilizer increased yield significantly and recorded (29.4%), (32.5%) and (46.5%) higher yield in T₁, T₂ and T₃ over control treatment. Therefore, application of gypsum fertilizer with the doses of 150 kg/ha could be the prominent fertilization along with the recommended doses fertilizer for Kohlrabi production.
