EFFECT OF MANURE AND POTASSIUM ON GROWTH AND YIELD OF TOMATO

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 effect of different manures and potassium on growth and yield of tomato. The experiment consisted of two factors: Factor A: Three levels of manures. The treatments are M ii

0 : 0 (control), M 1 : cowdung 15 t ha

and M 2 : vermicompost 3.75 t ha -1 . Factor B: Four levels of potassium. The treatments are K 0 : (control); K 1 : 200 kg MOP ha -1 ; K 2 : 220 kg MOP ha and K 3 : 240 kg MOP ha -1 . There were 12 treatment combinations. The experiment was laid out in Randomized Complete Block Design with three replications. Data on different growth and yield contributing characters and yield were recorded to find out the optimum level of manure and potassium on tomato. In case of manure, maximum yield hectare -1 (69.10 t/ha) were recorded from M treatment while the minimum result was from the control. For potassium, the maximum yield hectare -1 (69.43 t/ha) were recorded from the K treatment while the minimum from control. Due to interaction effect of manure and potassium application, the maximum yield hectare -1 (79.96 t/ha) was recorded from the M 2 K treatment combination and the minimum from control. So, it can be concluded that, the combination of 3.75 t/ha vermicompost with 220 kg MOP ha -1 2 is the appropriate practice for tomato production.
