ASSESSMENT OF THE EFFECTS OF ZINC AND COPPER ON THE GROWTH AND YIELD OF TOMATO | Asian Journal ....

From October 2016 to March 2017, a pot experiment was conducted at the Soil Science Department of Sher-e-Bangla Agricultural University, Dhaka, to investigate the effects of Zn and Cu on tomato growth and yield. T0=Control, T1=Recommended dose of fertiliser (N160P50K100S20) kg/ha, T2=75 percent NPKS from inorganic fertiliser and 25% NPKS from cowdung, T3=Recommended dose of fertiliser with Zn and Cu (N160P50K100S20+Zn4+Cu4) kg/ha, T4=Recommended dose of fertiliser with Cu (N160P50K100S20 +Cu4) kg/ha, T With one factor and three replications, the experiment was set up in a Randomized Complete Block Design (RCBD). Data on growth, yield contributing characters, and yield were collected, and the results were statistically evaluated to determine the treatment impacts. The use of Zn and Cu with other chemical fertilisers had a considerable impact on all plant metrics. The suggested amount of Zn and Cu fertiliser (N160P50K100S20+Zn4+Cu4) kg/ha produced the tallest plant, the most leaves per plant, the most branches per plant, the most flower clusters per plant, and the most flowers per plant. T3 therapy resulted in an increased number of fruits per plant. The amount of zinc and copper in tomato plants has a substantial impact on the number of fruits produced per plant. The T3 treatment produced the highest production of fruits per plant (347.60 g), while the control treatment produced the lowest yield of fruits per plant (183.73 g).
