The study was carried out at the Vegetable Research Farm of the Horticulture Research Centre, BARI during the period from October 2006 to April 2007. The experimental area is characterited by relatively scanty rainfall, low humidity, low temperature, short day, and long clear sunshine period during October to April. The experimental plot belongs to Madhupur Tract (AEZ-28). The soil PH was 6.4. having 1.64% organic mater, 0.087% total N, 29 µg/ml available P, 0.11 meq/100g exchangeable K, 0.22 µg/g B, and 1.8 µg/g Zn. The study consisted of four levels of boron and zinc viz., B0Zn0, B1.5Zn2.0, B2.0Zn4.0, B2.5Zn6.0 kg/ha and four levels of cowdung viz., 0, 10, 15, and 20 t/ha. Thus there were 16 treatment combinations. In addition to the levels of boron, zinc, and cowdung under investigation, 253 Kg N, 90 Kg P, 125 Kg K, and 6.6 Kg S (550 kg urea, 450 Kg TSP, 250 Kg MoP, 120 Kg gypsum per hectare) were applied. The sources of boron and zinc were boric acid and zinc oxide, respectively. The experiment was laid out in a RCB design with three replications, the unit plot being 2.4 x 2.4 m. Half of the quantity of cowdung, the entire quantity of TSP, gypsum, and 1/3 MoP were applied during final land preparation. The remaining cowdung, entire boron, and zinc were applied during pit preparation. The entire urea and the rest of MoP were applied in three equal installments at 15, 30, and 50 days after transplanting. The test variety was BARI Tomato-9. Inter cultural operations were done as and when necessary. Data were collected on number of filled seeds per fruit, pulp weight, dry matter content, total soluble solid (TSS), acidity (Rangana,1994), ascorbic acid, lycopene content, chlorophyll- a and chlorophyllb according to Nagata et al.(1992), boron content (Hunter, 1980), zinc content (Rahayu et al., 2001), percent marketable fruit and shelf life (Mondal, 2000). From the middle rows of each plot middle six plants’ fruits were selected to record data. Data were analyzed statistically and means were compared by the Least Significant Difference (LSD) test.
