The experiment was conducted at the experimental field of Olericulture Division of Horticulture Research Centre (HRC), Gazipur, and five RARSs of BARI during the winter season of the year 2017-18. There were four selected inbred tomato lines (selected from the AVRDC supplied eight inbred tomato lines) viz.: SL0033=CLN3670B; SL0036= CLN3552C; SL0037=CLN3552B; and SL0038= CLN3125L-5x65 along with one local check BARI Tomato-19 (Newly developed processing tomato variety) was included in this study. Seeds of tomato entries were sown on 3rd week of October, 2017 and thirty days old seedlings were transplanted in the main plot on 3rd week of November, 2017. The crop was fertilized with cow dung 10 ton, N-253kg (urea- 550kg), P- 90kg (TSP-450kg), K-125 (MoP-250kg), S-21kg (Gypsum-116kg), Zn-4.9kg (Zinc Sulphate-14kg) and B-2kg (12kg) per ha, respectively. Half of the quantity of cow dung, entire P and half of the K, entire zinc and boron were applied during land preparation. The remaining half of the cow dung was applied during pit preparation. The rest of K and entire N were applied at three equal installments at 15, 30 and 45 days after transplanting. For safer tomato production, crop management, plant protections, irrigation and other intercultural operations (weeding, pruning and staking etc.) were done as and when necessary following suggested cultural practices for tomato production as mentioned in the guide line of AVRDC. The experiment was laid out in the randomized complete block design (RCBD) with 3 replications. Five treatment combinations were randomly allotted in each block. The size of a unit plot was 4.8 × 1m, and the plant spacing was 60cmx40cm. Each unit plot contained 2 rows of plants (24 plants/ plot) and border rows were planted with same tomato entries in the four sides. The space in between plots was 50cm too. Data on yield and yield attributing parameters with qualitative traits were recorded from 20 inner plants of each plot escaping border plants following AVRDC guide line as follows: Tomato fruits were started harvesting at breaker stage from 20 inner plant of each treatment. In every harvest marketable (worth selling) and non- marketable ((with defects such as cracking, blossom end rot, gray wall, blotchy ripening, puffiness, sunscald, cat face, insect damaged fruits, etc.) were counted and weighed. Following same manner, there were four harvests done and data on days to 50% flowering, growth habit, Biotic stress ratting, length of fruit, fruit breadth, number of fruits per plant, yield of fruits per plant, average fruit weight, yield of fruits per plot, yield of fruits per hectare and qualitative traits (firmness, measurements of surface colour, ascorbic acid, PH , dry matter and viscosity-processing attributes analyzed in 2015 at headquarter).The recorded quantitative data were analyzed statistically and treatments means were compared by Least Significant Difference (LSD) test following R Software 3.1.2 (Anon., 2015).
