The study was laid out in a split-split plot design with three replications. The trials comprised three factors: 1) three tomato varieties viz, BARI F1Tomato-5, BARI F1Tomato-6 and BARI F1Tomato-7;2) four levels of calcium (Ca) treatment (40 ppm, 60 ppm, 80 ppm, 120 ppm) and 3) mulching practices. Results of the experiment revealed that fresh yield of tomato was significantly increased by applying mulching practices due to conservation of soil moisture by mulches and therefore, reduced Ca-deficiency symptoms. The highest number of fruits per plant and fresh yield were obtained from the variety BARI F1Tomato-5. The same trend of yield and yield contributing parameters were likely to be better by using T3?treatment (80 ppm) than those of other treatments. In contrast, BARI F1Tomato-7 variety in control treatment without mulching practice gave poor quality and yield of tomato. Results suggested that BARI F1Tomato-5 variety receiving 80 ppm calcium treatment with mulching condition exposed better quality, yield and yield contributing characters of tomato. However, the T3?treatment (80 ppm) with mulching would be recommended as the best combination to grow BARI F1Tomato-5 for the farmers in Bangladesh.展开更多
