RESPONSES OF BRINJAL TO DIFFERENT PLANT GROWING STRUCTURES AND COMPOSITION OF GROWING MEDIA IN THE ROOFTOP GARDEN

Abstract

This experiment was carried out at the rooftop garden of the Department of Agricultural Botany, Sher-e-Bangla Agricultural University, Dhaka-1207, Bangladesh from May 2018 to October 2018 to evaluate responses of brinjal to different plant growing structures and different growing media in the rooftop garden. The experiment consisted of two factors, factor A-plant growing structures, viz., S 1 = Plastic pot, S = Earthen pot and factor B-six different plant growing medium viz. M 0 2 =Soil 100%(w\w) with Recommended Dose of Inorganic Fertilizers (RDIF)/ (control), M 1 =Soil 80% (w\w) +20% Cow dung (w\w) along with RDIF, M =Soil 60% (w\w) + Cow dung 40% (w\w) along with RDIF, M =Soil 90% (w\w) +10% Vermicompost (w\w) along with RDIF, M 4 3 =Soil 80% (w\w) +20% Vermicompost (w\w) along with RDIF and M =Soil 70% (w\w) +20%Cowdung (w\w) +10% Vermicompost (w\w) along with RIDF. The factorial experiment was laid out in a Completely Randomized Design (CRD) with four replications. The experimental result such as morphological character and yield of brinjal significantly influenced by different plant growing structures and plant growing media and their combination. As for plant growing structures, the plastic pot (S ) gave the highest plant height, number of leaves per plant, branch per plant, flowers per cluster, flowers per plant, fruit length, fruit diameter, fruits per plant. The highest yield of fruits per plant (740.16 g) was obtained from plastic pot(S 1 ) and Soil 70%(w\w) +20% cow dung(w\w) +10% vermicompost(w\w) along with RDIF marked as S 1 M . The lowest yield of fruits per plant (144.72 g) was obtained from earthen pot and Soil 100% (w\w) along with RDIF marked as S 5 2 M . Considering the stated findings, it may be concluded that BARI Begun-8 planted in plastic pot and Soil 70% (w\w) +20% Cow dung (w\w) +10% Vermicompost (w\w) along with RDIF would be beneficial for increasing the yield of brinjal during kharif season in the rooftop garden under the climatic conditions of SAU. 0 2 5 2
