PRODUCTIVITY AND PROFITABILITY OF TOMATO AS INFLUENCED BY MICRONUTRIENTS

Abstract

The experiment was conducted in the Horticultural Farm of Sher-e-Bangla Agricultural University, Dhaka during the period from October 2015 to March 2016 to find out the productivity and profitability of tomato as influenced by micronutrients. This is a single factor experiment and consisted of 11 treatments. The treatments are the combination of different doses of micronutrients according to North Caroline University law, USA. The treatments are T 0 : Zn 0 B 0 Cu 0 kg ha -1 , T 1 : Zn 0 B 4 Cu 2 kg ha -1 , T 2

kg ha -1 , T 3 : Zn 6 B 4 Cu 2 kg ha -1 , T 4 : Zn 8 B 4 Cu 2 kg ha -1 , T 5 : Zn 8 B 0 , T 6 : Zn 6 B 2 Cu 0 kg ha -1 , T 7 : Zn 6 B 6 Cu 2 kg ha -1 , T 8 : Zn 6 B 4 Cu 0 : Zn 4 Cu 2 kg ha

B 4 Cu 1 kg ha -1 and T 10 : Zn 6 B 4 Cu 3 kg ha -1 . Recommended doses of cowdung, Urea, TSP and MP were also used as basal dose. The experiment was laid out in Randomized Complete Block Design with 3 replications. Maximum number of clusters plant -1 (9.35), number of flowers cluster -1 (7.75), number of fruits cluster -1 (4.25), individual fruit weight (92.50 g), dry matter content of fruit (15.37 %), TSS (8.76 %), yield of fruit plant -1 (2.88 kg), and the maximum yield hectare -1 (96.00 t/ha), were recorded from the T 3 treatment while the minimum results were observed from the T 0 . From economic point of view, the treatment T 3 gave the highest economic return (Tk. 674944 ha ) with 2.37 BCR. So, economic analysis revealed that the treatment combination of T 3 appeared to be the best for achieving higher productivity and profitability of tomato.
