EFFECT OF ZINC AND BORON ON THE GROWTH AND YIELD OF BARI TOMATO-15

Abstract

An experiment was carried out at the Soil Science research field, Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207 during the period from November 2020 to April 2021 to find out the effect of micronutrients (Zn and B) on the growth and yield of BARI Tomato-15. The experiment was laid out in a Randomized Completely Block Design (RCBD) having twelve (12) treatments with three replications. The unit plot size was 6 m ii 2 . There were 12 different combination of zinc and boron treatments (T 1 , T 2 , T 3 , T 4, T 5, T 6, T 7 , T 8 , T 9, T 10, T 11 and T 12 ) they were distributed randomly in individual plots. The total number of plots was 36. Different levels of zinc and boron as micronutrient had significantly varied the all yield and growth parameters. It was clearly found that, the maximum plant height (99.50 cm), number of branches plant -1 (11.73), number of leaves(160.67), number of cluster plant -1 (9.80), number of fruits cluster -1 (5.00), number of fruitsplant (42.45), diameter of a fruit (18.88 cm), single fruit weight plant -1 (79.63 g), weight of fruits plant -1 (3.47 kg) and yield (101.43 t ha -1 ) were observed from T 8 + Zn 50% )treatment. On the other hand, the minimum plant height (81.67 cm), number of branches plant -1 (9.07), number of leaves (146.40), number of cluster plant (8.07), number of fruits cluster -1 (4.20), number of fruitsplant (17.33 cm), single fruit weight plant -1 -1 -1 (B 150% -1 (30.21), diameter of a fruit (61.30 g), weight of fruits plant (1.85 kg) and yield (55.52 t ha -1 ) were observed from T 1 treatment that was control. The results of the present investigation revealed that tomato can be grown successfully at the use of 150% of boron and 50% of zinc, tomato gave more yield. The findings of the present investigation clearly indicated that the efficient use of boron and zinc doses and growing tomato is a viable option for increasing income of farmers.
