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

Abstract

A study was conducted in field at the Agricultural Research Farm in Hajee Mohammad Danesh Science and Technology, Dinajpur, during November 2016 to April 2017 to determine the effect of drip irrigation over the other conventional methods on the growth and yield of chili CV, namely BARI Morich-1. There were four irrigation treatment viz. control (T0), furrow (T1), boarder (T2), and drip irrigations (T3). The area sizes of land were 17.5 m2 . Four plants of one verity were transplanted in two rows alternatively in each plot. Irrigation water was applied at three growth stages viz. vegetative (0-30 DAT), flowering (36-60 DAT), and fruit development stages (65-100 DAT) based on field capacity and soil moisture depletion .From the experiment it was observed that about 100 to 150 % water could be saved in drip irrigation treatment as compared to other conventional methods. The yield of chili in drip irrigation was found 8.7tha-1 . The water productivity under treatments T1, T2 for BARI Morich-1 were found 11Kgm-3 and 14 Kgm-3 respectively.
