MORPHOLOGICAL STUDY AND ECONOMIC CONSIDERATION OF CAULIFLOWER CULTIVATION ON ROOFTOP GARDEN USING VARIOUS COMPOSTS

Abstract

The experiment was conducted at the sixth floor of housing no. 64, road no. 6/A, Dhanmondi 13 during the period from November 2019 to July 2020. The experiment was laid out in CRD having single factors with three replications. The treatments of this experiment were T = Control (recommended dose of chemical fertilizers), T 1 0 = Vermicompost (10 t ha -1 ) + recommended dose of chemical fertilizers, T 2 = Sawdust (15 t ha -1 ) + recommended dose of chemical fertilizers and T 3 = Cowdung (20 t ha -1 ) + recommended dose of chemical fertilizers. The seedlings of the vegetable (BARI Fulkopi-2) was collected from Bangladesh Agricultural Research Institute, Joydebpur, Gazipur. From the results the maximum pure curd weight per plant (551.60 g), yield per plot (3.95 kg) and yield per hectare (19.75 t) were observed from T (vermicompost @ 10 t ha -1 1 + recommended dose of chemical fertilizers) treatment. The benefit cost ratio (BCR) was found to be the highest (3.33) in the treatment of T

(vermicompost @ 10 t ha -1 + recommended dose of chemical fertilizers). Thus it was apparent that vermicompost treatment gave the highest yield per hectare (19.75 t) than the other treatments (sawdust and cowdung) and the highest gross return (Tk. 395000.00). The results clearly showed that rooftop is suitable for vegetables production and yield at the rooftop garden.
