EFFECT OF BIOCHAR AND WATER STRESS ON THE GROWTH AND YIELD OF WHEAT

Abstract

The experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University, Dhaka during the period from December 2016 to April 2017 to observe the effect of biochar and water stress on the growth and yield of wheat. In this experiment, the treatment consisted of three doses of biochar viz. BC 1 = Control, BC 2 = 5 ton biochar ha ii -1 , BC 3 = 10 ton biochar ha and four different water stress viz. water stress, WS 1 = regular irrigation, WS = skipped irrigation at crown root initiation stage, WS = skipped irrigation at booting stage, WS 4 3 = skipped irrigation at heading and flowering stage. The experiment was laid out in two factors Randomized Complete Block Design -1 , leaf length, Number of effective tillers hill , ear length, number of spikelets per spike, number of grain per spike, grain yield was found from biochar 5 ton biochar ha -1 . The highest grain yield ha

-1 .The maximum plant height, Number of leaf plant -1 , leaf length, Number of effective tillers hill , ear length, number of spikelets per spike, number of grain per spike ,yield was attained from skipped irrigation at booting stage.The maximum yield

-1

-1 with skipped irrigation at booting stage. BARI Gom 27 coupled with 5 ton biochar ha and skipped irrigation at booting stage was found to be a promising practice for good yield.
