Postharvest and Agro-processing
The experiment was conducted at the experimental field of Olericulture Division of Horticulture Research Centre (HRC), BARI, Gazipur, Bangladesh during the winter season of the year 2015-16. The experiment filed was prevailed loamy soil having PH 6.5 with well drained location. 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-5 x 65 along with one local check (AVTO01139-advance processing tomato line) was included in this study. Seeds of tomato entries were sown on 10-10-2015 and thirty days old seedlings were transplanted in the main plot on 09-11-2015. The crop was fertilized with cow dung 10 ton, N-253 kg (urea- 550 kg), P- 90 kg (TSP-450 kg), K-125 (MoP-250 kg), S-21 kg (Gypsum-116 kg), Zn-4.9 kg (Zinc Sulphate-14 kg) and B-2 kg (12 kg) 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 60 cm x 40 cm. 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 50 cm 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).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).
