Abstract/ Executive Summary:

Staking and pruning could improve the yield of tomatoes. The present investigation was aimed to find out the staking and pruning effect on tomato production. The research was done on ''Roma VF'' tomato in the coastal region of Bangladesh to determine the effect of staking and pruning on the growth and yield of tomato plants. The experiment was laid out in Randomized Complete Block Design (RCBD) on a single variety tomato plant with three treatments (no staking and no pruning, only pruning, staking, and pruning) and three replications in the coastal region. The parameters of the study were plant height (cm), number of branches per plant, number of leaves per plant, number of flowers per plant, number of fruits per plant, fruit Brix (%). Among all treatments staking and pruning was responsible for maximum average height (46 cm), number of branches per plant (7.67), number of leaves per branch (21), number of flowers per plant (18), number of fruits per plant (8.33) and fruit Brix (11.3%). The statistical analysis of data showed the significant effect of treatments on tomato plants. Among all treatments staking and pruning is the best treatment, and it is suitable for farmers in tomato production.

End Date: 00-00-2018

Program Area: Crop-Soil-Water Management

Commodity: Tomato

Objectives:

To find out a suitable agronomic technique for maximum growth and yield of the ''Roma VF'' tomato variety.

Methodology:

The experiment was conducted during the period of November 2018 in the research field of the Agriculture Department, Noakhali Science and Technology University, Bangladesh. The climate of the experimental area was temperate in nature. The soil was sandy loam in texture to slightly saline which a pH was 7.5-8.3. This experiment used local variety ''Roma VF'' and the experiment was laid out in Randomized Complete Block Design (RCBD) with three treatments (no staking and no pruning, only pruning, staking, and pruning) and three replications. ''Roma VF'' is a determinate type of plant. Determinate type of plants is not heavily pruned. Pruning removes small shoots where each leaf joins the stem. Remove the shoot sucker when they are less than 4 inches long to avoid injuring the plant. Staking requires wooden or metal stakes 3 to 4 feet long for determinate varieties. When staking determinate varieties, prune only once to remove the first suckers. In this experiment three treatments were considered: T₁= No staking and no pruning on the tomato plant, T₂= Only pruning on the tomato plant, T₃= Staking and pruning on tomato plant and replications: 3. Tomato seedlings were raised in three seedbeds of 3.0 m × 1.0 m size. In each seedbed, seeds were sown on November 15, 2018. After sowing, seeds were covered with light soil. The emergence of the seedlings took place 6 to 7 days after sowing. 30 days old seedlings were transplanted to the experimental field. The plot size was 2.8 m × 2.0 m and spacing was 70 cm × 50 cm. Data on the following parameters were recorded from the experimental plot (no staking and no pruning on the tomato plant, only pruning on the tomato plant, staking and pruning on the tomato plant). The height of each plant was measured (cm) from the base of the plant to the apex with a tape measure. The height of the tomato plants was recorded at 30, 45, and 60 days after transplanting. The number of branches per plant was recorded at 30, 45, and 60 days after transplanting. Randomly selected branches of plants were used for the measurement of leaves per branch at 30, 45, and 60 days after transplanting. The number of flowers per plant was recorded at 45, 55, and 65 days after transplanting. The number of fruits per plant was recorded at 55, 70, and 85 days after transplanting. The individual fruit Brix (%) of each treatment plot was done 90 days after transplanting by refractometer. The Brix (%) was estimated by using a correction factor chart. All of the data were recorded by counting through eye estimation. Data were analyzed using SPSS statistical software and Microsoft Office Excel 2013 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 a 5% level of probability.

Achievement/Findings:

From the result, it was analyzed that staking and pruning had a significant effect on tomato plant growth and yield. Staking and pruning were responsive to maximum average height (46 cm), number of branches per plant (7.67), number of leaves per branch (21), number of flowers per plant (18), number of fruits per plant (8.33), and fruit Brix (11.3%). It was observed that staking and pruning on plants resulted in higher average growth and yield than only pruning as well as no staking and no pruning.
