Abstract/ Executive Summary:

The study was conducted at rooftop of the Mushroom laboratory, Horticulture Research Centre (HRC), Bangladesh Agricultural Research Institute (BARI), Gazipur from July 2016 to June 2017. Nine Treatments viz., T1= Plastic box 1, T2= Plastic box 2, T3= Plastic box 3, T4= Plastic box 4, T5= Plastic box 5, T6= Plastic box 6, T7= Plastic box 7, T8= Half drum, T9= Sac/ Multilayer box and three rooftop garden models viz., Model 1, Model 2, Model 3were included in the study. Each model consists of 22 types of vegetables. Considering the 3 models, there was a narrow difference in term of vegetable yield and prices. The main cause behind it was the number of vegetables was the same (22) in all models. Just rearrange the vegetables within the treatments and type of production system viz., single cropping, intercropping and relay cropping. So, on a roof garden from a 10 m² / 100 ft² area, anybody can follow any model preferably Model 1 and Model 2, in which vegetable price (2270 tk) and yield (73 kg) were higher, respectively. This study was just an I-year result, so after another year's trial, it may be concluded which model is best in terms of yield and price.

Objectives:

Objective

Development of a suitable model on the rooftop for vegetable production
To accommodate maximum vegetables in an unit area (10 m² / 100 ft²)
To get year- round nutrition supply

Methodology:

The experiment was conducted at rooftop of the Mushroom laboratory, Horticulture Research Centre (HRC), Bangladesh Agricultural Research Institute (BARI), Gazipur during July 2016 to June 2017. Three rooftop garden models were included in the study. Nine Treatments viz., T1= Plastic box 1, T2= Plastic box 2, T3= Plastic box 3, T4= Plastic box 4, T5= Plastic box 5, T6= Plastic box 6, T7= Plastic box 7, T8= Half drum, T9= Sac/ Multilayer box and three model viz., Model 1, Model 2, Model 3were included in the study. Each model consists of 22 types of vegetables. The seeds were sown or seedlings were transplanted on the plastic box, half drum, sac, multilayer box according to the season of concern vegetables. The planting methods were single cropping, intercropping, or relay cropping to accommodate maximum vegetables within a year. The unit plot size 10 m² / 100 ft²and 9 treatments were accommodated in a model. The soil was fertilized with cowdung, cocodust and vermicompost @ 60:50:5:2 in a weight basis, respectively. The intercultural operations (weeding, irrigation, etc.) were done as and when necessary. Data on yield (kg/treatment) was recorded from each model and calculated product value with the local retail price (Tk). The information on different quantitative characters was statistically analyzed.

Achievement/Findings:

Considering the 3 models, there was a narrow difference in terms of vegetable yield and prices. The main cause behind it was the number of vegetables was the same (22) in all models. Just rearrange the vegetables within the treatments and type of production system viz., single cropping, intercropping and relay cropping. So, anybody can follow any model preferably Model 2 and Model 1, in which vegetable price (2306 tk, 2278 tk, respectively) and yield (76kg, 68.5 kg, respectively) were higher. This study was just 1-year result, so after another year's trial, it may be concluded which model is best in terms of yield and price.
