Abstract
The field experiment was carried out at the Research farm of Central Agricultural University, Imphal, Manipur, during the rabi seasons of 2016-17 and 2017-18, to study the interaction effect of Zinc and Boron on growth, yield, and yield attributes of tomato (Pusa Ruby). There were ten treatments viz., T1 (Zn0.0+B0.0), T2 (Zn2.5+B1.0), T3 (Zn2.5+B1.5), T4 (Zn2.5+B2.0), T5 (Zn5.0+B1.0), T6 (Zn5.0+B1.5), T7 (Zn5.0+B2.0), T8 (Zn10+B1.0), T9 (Zn10+B1.5) and T10 (Zn10+B2.0) with three replications were laid out by FRBD design. The combined effect of zinc and boron showed a significant effect on the number of fruits plant-1, fruit weight plant-1, and yield ha-1, whereas there was no significant effect on plant growth parameters (plant height). Among the treatments, the T10 (Zn10+B2.0) treatment exhibited a significantly increased in the number of fruits plant-1 (35.83 in the first year and 36.52 in the second year), fruit weight plant-1 (1.62 kg in the first year and 1.76 kg in the second year.), highest fruit yield (60.06 t ha-1 in the first year and in 65.1 t ha-1 in the second year) was produced from the treatment combination of 10 kg of Zn ha-1 and 2.0 kg B ha-1 in both years than the control treatment (Zn0.0+B0.0).
