Abstract/ Executive Summary:

The investigation was conducted at the Horticulture Farm, Bangladesh Agricultural University (BAU), Mymensingh, Bangladesh during the period from 2015 to 2016 to determine the performance of stem pruning on the growth and yield of tomato variety, Ratan. The experiment consisted of three treatments- no pruning, two stem pruning, and three stem pruning laid out in a randomized complete block design with three replications. The shoots had significant effects on the plant height of two and three stem pruning over no pruning. The number of flowers, fruit length, fruit diameter were significantly higher in double stem pruning over triple stem pruning and no pruning. The number of fruits per cluster, the number of ripe fruits per plant, individual fruit weight, fruit weight per plant, and fruit yield per plot were higher in double stem pruning followed by triple stem pruning over no pruning. Moreover, double stem pruning had a higher yield (57.16 t/ha), afterward triple stem pruning (54.55 t/ha) over no pruning (49.77 t/ha).

Keywords: Tomato, Stem pruning, Growth, Yield

Location: Horticulture Farm, Bangladesh Agricultural University (BAU), Mymensingh, Bangladesh

Start Date: 00-00-2015

End Date: 00-00-2016

Program Area: Crop-Soil-Water Management

Commodity: Tomato

Objectives:

To find out a suitable pruning practice for maximum growth and yield of tomatoes.

Methodology:

This investigation was conducted at the Horticulture Farm, Bangladesh Agricultural University (BAU), Mymensingh, Bangladesh during the period from 2015 to 2016 to study the performance of stem pruning on the growth and yield of tomatoes. The texture of the soil was silty-loam with a pH of 6.6. The climate of the experimental area was subtropical in nature. The planting material was seeds of Ratan, a high-yielding indeterminate type tomato genotype collected from Horticulture farm, BAU. The seedlings were raised in five seedbeds of 3 x 1 m². 35 days old seedlings were transplanted to the experimental field following RCBD with 3 replications. The plot size was 2.8 x 2.0 m² and spacing was 70 x 50 cm². Standard management practices were done for tomatoes. Three pruning operations were practiced-P₁, P_2, and P₃ [No pruning (No stem pruning practices), Double stem Pruning (Pruning plants keeping double stem), and Triple stem Pruning(Pruning plants keeping triple stem)]. Pruning was started 35 days after transplanting and continued throughout the whole period of plant growth leaving the required number of stems as per treatments. Data were collected on the following parameters- plant height, days to first flowering, number of flower clusters per plant, flowers per cluster, flowers per plant, fruit cluster per plant, fruits per cluster, ripe fruits per plant, fruit length, fruit diameter, the weight of individual fruit, the weight of fruits per plant, the weight of fruits per plot and fruit yield per hectare. The data on different yield components and yields were statistically analyzed using SPSS software to find out the significance of the difference among the treatments. The analysis was performed by F- test and the significance of the difference between pairs of treatment means was evaluated by Least Significant Different (LSD) test at 5% and 1% level of probability.

Achievement/Findings:

From the above findings of this study, it could be concluded that two stem pruning showed a higher number of flowers per plant (180.31), longer fruit (4.90 cm), and greater fruit diameter (5.88 cm) over triple stem pruning and no pruning. A higher number of fruits per cluster, number of ripe fruits per plant, individual fruit weight, fruit weight per plant, and fruit yield were found followed by triple stem pruning over no pruning. Total yield per hectare was tremendously increased in double pruning (57.16 t) followed by triple stem pruning (54.55 t) over no pruning (49.77 t). In short, double-stem pruning increases tomato growth and yield over triple stem pruning and no pruning.
