PRODUCTION OF TOMATO USING SOILLESS PLANTING MEDIA ON ROOFTOP

Abstract

The field experiment was conducted at the rooftop of Dr. M. A. Wazed Miah Research Centre at Sher-e-Bangla Agricultural University in Sher-e-Bangla Nagar, Dhaka1207, Bangladesh during mid-November, 2021 to mid-March, 2022 for production of

tomato

using soilless planting media on rooftop. BARI tomato-21 was used as planting material in this study. The experiment consisted of four treatments: T 1 = Soil (Control), T 2 = (Coconut coir chip 50%: Charcoal 50%), T 3 = Coconut coir chip 50%: Pumice bricks (from Brick shards) 50%, T 4 = Coconut coir chip 50%: Perlite 50%. The experiment was laid out in a Completely Randomized Design (CRD) with three (3) replications. Total 12 unit drums were made for the experiment for 4 treatments. Data on different growth and yield parameter of tomato were recorded and significant variation was recorded for different treatments. Different treatments used in rooftop significantly affected on all studied parameters. The highest plant height (46.51, 61.193 and 88.74 cm), number of leaves plant -1 (35.82, 40.39 and 66.38 cm) and number of branches plant -1 (6.27, 7.51 and 8.39) was found at 20, 40 and 60 DAT was found in T 2 . The number of fruit plant -1 and marketable fruitplant -1 of tomato (27.10 and 24.38) at 60 DAT was found in T 2 (Coconut coir chip 50%: Charcoal 50%). The highest fruit length and breadth (5.08 and 3.64 cm) at 60 DAT was found in T 2 . The highest individual fruit weight (60.55 g) at 60 DAT was found in T 2 . The highest fruit yield (1.68 kg plant -1 and10.11 kg drum -1 ) was found in T 2 followed by T 4 .
