EFFECT OF DRIP IRRIGATION OVER CONVENTIONAL METHOD ON THE GROWTH AND YIELD OF TOMATO

Abstract

The experiment was conducted from 27 October, 2016 to 27 February 2017 at Hajee Mohammad Danesh Science and Technology University (HSTU) farm, Dinajpur to determine the effect of drip irrigation over the other conventional methods on the growth and yield of tomato namely BARI tomato-7. There were four irrigation treatments viz. control (TO), furrow (T1), border (T2), and drip irrigation (T3) having three replication for each. The size of each plot was 1m × 1m. Four plants were transplanted in two rows in each plot. Irrigation water was applied at three growth stages viz. vegetative (0-30), flowering (35-60), and fruit development stages (65-100) based on field capacity. From the experiment it was observed that yield of tomato in drip irrigation 63.8 tha-1 and about 184 % water could be saved in drip irrigation compared to other conventional methods. The yield of tomato in drip irrigation was found to be 63.8 tha-1 and the water productivity under this irrigation was found to be 0.30tha-1 m -3 The water productivity under treatments T1 and T2 were 0.08, 0.09 tha-1 m -3 respectively.
