FFECTS OF PLANT VITALIZER (HB-101) ON GROWTH, YIELD AND NUTRIENT CONTENT OF TOMATO

Abstract

A field experiment was conducted during October 2019 to March 2020 in the farm of Sher-e-Bangla Agricultural University to study the effects of plant vitalizer (HB-101) on growth, yield and nutrient content of tomato. The experiment consisted of two factors: Factor A: two tomato varieties viz. V 1 : BARI tomato-2 and V : BARI tomato-15 and Factor B: 5 levels of HB-101 plant vitalizer viz. PV 0 2 : control (0 ml PV L : 1 ml PV L -1 , PV 2 : 2 ml PV L -1 , PV 3 : 3 ml PV L -1 and PV 4: 4 ml PV L -1 . The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. In case of different tomato varieties, the best performance for most of the parameters was obtained from V 2 (BARI tomato-15) and gave highest yield (59.47 t ha -1 -1 ), PV ) compared to V (BARI tomato-2) (57.87 t ha -1 ). In case of plant vitalizer, 3 ml PV L -1 (PV ) treatment showed best performance and gave highest yield (62.10 t ha -1 3 ) compared to other treatments. In case of combined treatments, V 2 PV 3 (BARI tomato-16 with plant vitalizer @ 3 ml L ) gave highest number of fruits plant -1 (28.80), single fruit weight (63.75 g), fruit weight plant -1 (1836.00 g) and yield (62.95 t ha -1 ) compared to other treatment combinations but in case of nutrients (N, P, K and S) content in tomato fruits V 2 PV showed nonsignificant

variation compared to other treatments. Above all considerations, treatment combination of V 2 PV 3 (BARI tomato-15 with plant vitalizer @ 3 ml L ) can be considered as the best then other treatments which

can be recommended for different tomato varieties to achieve higher yield and nutrient content.
