EFFECT OF BIOCHAR ON THE GROWTH AND YIELD OF WHEAT (Triticum aestivum L) UNDER REDUCED IRRIGATED CONDITION

Abstract

An experiment was conducted at the research field of Sher-e-Bangla Agricultural University, Dhaka-1207, to evaluate the effect of biochar on the growth and yield of wheat ii 1 = 0 t ha , B 3 = 4 t ha -1 , B 5 = 6 t ha -1 , B 6 = 8 t ha -1 -1 , B and three levels of water stress such as W = Regular irrigation, W 2 = Irrigation skipped at booting stage, W =Irrigation skipped at heading and flowering stage. There were 45-unit plots and the size of the plot was 2m × 1.5m i.e. 3m 2 3 . There were 15 treatments combination. Wheat seed of cv. BARI Gom-29 was sown as planting material. The tallest plant -1 2 = 2 t ha

Biochar application in soil can enrich soil organic matter as well as improve soil properties resulting improved aeration and better water holding capacity of soil.
