EFFECT OF GRAFTING AND CUL TIV ARSON THE GROWTH AND YIELD OF TOMATO

Abstract

study was conducted al Bangladesh Agricultural Research Institute (BARJ), Joydebpur, Gazipur to study the effect of grafting among three tomato varieties for producing wilt free tomato. The treatments of the experiment consisted of three tomato varieties viz. BARI Tomato-3, BARI Tomato-4 and BARJ Tomato-6 and rootstock Solanum sisymbriifolium. Tomato varieties had significant influence on grafting success, days to 50% Dowering, plant height, days to harvest, fruit characters, bacterial wilt, virus, plant mortality and yield contributing characters. The result of the experiment further revealed that maximum grafting success ( 46.79%) number of fruit (26.06), yield per plant (1.73 kg) and yield per hectare (76.36 ton) was obtained from the variety BARI Tomato-6.Grafting had significant inlluencc on the above mentioned parameters including incidence of bacterial will. The highest harvesting duration (76 days), no wilt incidence and higher yield (64.32 ton/ha) were recorded when tomato plant was grafted. Grafted tomato plants had maximum harvest duration (76.22 days), no wilt incidence and produced higher yield. (64.32 ton I ha) When the combined effect of varieties and rootstock were taken into consideration, highest yield (79.74 ton/ha) was obtained from graft BARI Tomato-6. But BARI Tornato-J had also highest yield (78.21 ton/ha) and early harvest when it was grafted. Therefore, it may be recommended that tomato varieties may be grafted on resistant wild Solanutn rootstocks for controlling bacterial wilt and gelling higher yield
