Abstract
Three types of tomato seedlings viz., polybag raised seedlings (polybag seedling), seedbed raised seedlings (normal seedling) and grafted seedlings (tomato grafted on wild brinjal) of BARI hybrid tomato-4 were evaluated under with and without hormone application system during the summer season of 2014 at the experimental field of Sylhet Agricultural University with view to assessing the influence of grafting and hormone application on tomato yield during summer. Seedling types had significant influence on fruit yield and plant mortality. Only 3.5% plants were infected with bacterial wilt when grown from grafted seedling while it was 18% and 20% when the plants raised from normal and polybag grown seedling, respectively. Thus the higher survivability of plants in the grafted plot ensured much higher fruit yield acre-1 (18 ton) than those of normal seedling (13.15 ton) and polybag grown seedling (12.80 ton). Application of paracholorophenoxy acetic acid had significant influence on higher tomato production. The plants applied with hormone produced 979.50 g of fruits plant-1 while it was only 724.48 g in untreated plant. However, the highest fruit yield plant-1 was recorded from the grafted tomato plants (1.06 kg) and normal seedling grown plant (1.08 kg) when treated with hormone while it was the lowest for normal types of seedling at without hormone application (0.59 kg plant-1). Results revealed that the high scope of improving tomato yield during summer using grafted seedling along with hormone application in Sylhet region.
