Effect of Organic and Inorganic Fertilizers on Growth and Yield of “Tomaloo”

Abstract

An experiment was carried out at the Agricultural Research Field of IUBAT, Dhaka, Bangladesh from October 2022 to April 2023 to investigate the Effects of organic and inorganic fertilizers on the growth and yield of “Tomaloo” in continuation of previous research. “Tomaloo” is a wonder plant created by grafting between a potato and a tomato plant which bears tomato in the upper parts of the plant and the potato grows underground. The experiment was set following Randomized Complete Block Design consisting of four treatments and three replications. The treatments used in the study were F0- Without fertilizer, F1-Organic fertilizer, F2-Chemical fertilizer, and F3-Organic + Chemical fertilizer. The tomato variety BARI-20 (Cherry Tomato) and Potato variety Diamant were used in this experiment. From the study, significant differences were observed in terms of growth and yield components. Most of the studied parameters such as plant height, number of leaves, number of branches, number of flower clusters per plant, number of fruits per cluster, number of fruits per plant, fruit length, fruit diameter, single fruit weight, and total fruit yield per plant of Tomato and Potato showed significant difference by the different fertilizer treatments. The maximum “Tomaloo” plant growth was found in the F1 treatment and the minimum was recorded in the F0 treatment. The highest yield of Tomato (373.58 g) and Potato (204.90 g) per plant of “Tomaloo” was recorded in the F1 treatment and the lowest yield of Tomato (171.95 g) and Potato (117.37 g) per plant was recorded in the F0 treatment. It was revealed from the present findings that maximum growth and yield of tomato and potato were obtained from “Tomaloo” plant in response to F1 (Organic fertilizer) fertilizer treatments.
