Abstract

A pot experiment was carried out on the rooftop of a building at Charfasson town Bhola to evaluate the growth and yield performance of strawberry (Fragaria ananassa) as influenced by different doses of vermicompost and inorganic fertilizers in the winter season of 2020-2021. Each pot was filled with ten kg soil and arranged in a completely randomized design having seven treatments with three replications. Treatments were T1: Control (-VC), T2: 5 t VC/ha, T3: 10 t VC/ha, T4: 15 t VC/ha, T5: 20 t VC/ha, T6: 25 t VC/ha, and T7: 50% RDF NPK (40 - 15-25 kg/ha). Different agronomic parameters were measured at the intervals of 30, 60, 90, and 120 days after sowing of seeds. All the treatments of vermicompost showed better responses in agronomic parameters than the control treatment. Among them, T5 treatment tends to show significantly (p<0.05) higher plant height (18.5 cm), number of the leaf (54/plant), root length (15.50 cm), first flowering (at 61 days), fruit length (5.75 cm), fruit diameter (13.75 cm), number of fruits (15/plant), the average weight of fruit (14.50 g), the fresh yield of fruits (13.59 t/ha), fresh weight of root (10.41 g/plant), fresh weight of reproductive structure (3.12 g/plant), weight of the dry reproductive structure (3.12 g/plant) and benefit-cost ratio (9.37). T6 treatment showed significantly (p<0.05) higher leaf area (49.00 cm2), fresh weight of petiole (4,61 g/plant), the weight of dry root (2.20 g/plant), weight of dry leaf (5.87 g/plant), weight of dry petiole (1.42 g/plant) and weight of dry biomass (12.48 g/plant). T2, T3 and T4 treatments showed significantly (p<0.05) higher growth than T7 treatment. The overall findings revealed that the application of vermicompost (20 t/ha) in the strawberry plant might be a suitable method in rooftop gardening to achieve its better agronomic and yield parameters in the southern parts of Bangladesh.

孟加拉国南部Charfasson地区屋顶不同剂量蚯蚓堆肥和氮磷钾肥料对草莓生长和产量的影响

在Bhola Charfasson镇的一座建筑物屋顶进行盆栽试验，以评估2020-2021年冬季不同剂量蚯蚓堆肥和无机肥料对草莓(Fragaria ananassa)生长和产量的影响。每盆填入10公斤土壤，按完全随机设计，7个处理，3个重复。处理分别为T1:对照(-VC)， T2: 5 t VC/ha, T3: 10 t VC/ha, T4: 15 t VC/ha, T5: 20 t VC/ha, T6: 25 t VC/ha, T7: 50% RDF NPK (40 - 15-25 kg/ha)。播种后30、60、90、120 d分别测定不同农艺参数。蚯蚓堆肥各处理的农艺指标均优于对照处理。其中，T5处理的株高(18.5 cm)、叶数(54个/株)、根长(15.50 cm)、初花(61 d)、果长(5.75 cm)、果径(13.75 cm)、果数(15个/株)、果平均重(14.50 g)、果鲜产量(13.59 t/ha)、根鲜重(10.41 g/株)、生殖结构鲜重(3.12 g/株)、干生殖结构重量(3.12 g/株)和效益成本比(9.37)。T6处理显著(p<0.05)提高了叶片面积(49.00 cm2)、叶柄鲜重(4.61 g/株)、干根重(2.20 g/株)、干叶重(5.87 g/株)、干叶柄重(1.42 g/株)和干生物量重(12.48 g/株)。T2、T3和T4处理的生长均显著高于T7处理(p<0.05)。总体结果表明，在孟加拉国南部地区，施用蚯蚓堆肥(20 t/ha)可能是一种适合屋顶园艺的方法，可以获得更好的农艺和产量参数。达卡大学。科学通报，30(2):283- 292,2021 (7)
