Abstract/ Executive Summary:

An experiment was conducted at BINA pot yard, Mymensingh during the winter season of 2017-18 to assess the effect of different levels of debranching on reproductive efficiency and yield of tomato mutant TM-4. The debranching levels were: i) Control, ii) Main stem (MS) only, iii) MS with 1 branch, iv) MS with 2 branches, v) MS with 3 branches and vi) MS with 4 branches. Control plants had 5-6 branches/plant. Recommended fertilizers and cultural practices were followed. The treatments were imposed after branch initiation and maintained up to harvest. The highest number of effective flower clusters, flowers and fruits plant^-1 were recorded in Main stem with 4 branches followed by MS with 3 branches. The plants of MS produced larger fruits. Fruit size and reproductive efficiency decreased with increasing branch number. The highest fruit yield plant^-1 was recorded in MS with 4 branches due to increase number of fruits.

Objectives:

To assess the effect of different levels of debranching on reproductive efficiency and yield of tomato

Methodology:

An experiment was conducted with a tomato mutant TM-4 at BINA pot yard, Mymensingh during the winter season of 2017-18. The debranching levels were: i) Control, ii) Mainstem (MS) only, iii) MS with 1 branch, iv) MS with 2 branches, v) MS with 3 branches and vi) MS with 4 branches. Control plants had 5-6 branches/plant. Recommended fertilizers and cultural practices were followed. The experiment was laid out completely randomized design with three replications. The treatments were imposed after branch initiation and maintained up to harvest. Data on number of flowers, effective flower clusters, yield and yield attributes were recorded. The collected data were analyzed statistically.

Achievement/Findings:

The highest number of effective flower clusters, flowers and fruits plant^-1 of tomato mutant were recorded in Main stem MS) with 4 branches followed by MS with 3 branches. In contrast, the lowest number of effective flower clusters, flowers and fruits plant^-1 were recorded in the treatment of MS only. The plants of MS produced largest fruits. Fruit size and reproductive efficiency decreased with increasing branch number. The highest fruit yield plant^-1 was recorded in MS with 4 branches due to increase number of fruits.
