APPLICATION OF BIOCHAR, RICE HUSK AND Trichoderma BIO-FERTILIZER FOR THE GROWTH, YIELD ATTRIBUTES AND YIELD OF WHEAT

Abstract

The experiment was conducted in Agronomy Research Field, Department of Agronomy, Hajee Mohammad Danesh Science and Technology University, Dinajpur-5200, Bangladesh from November 2022 to April 2023 to assess the effect of Biochar, Trichoderma and Rice husk on the growth, yield attributes and yield of wheat. The experiment consisted of two factors where one factor was varieties namely V1 (BWMRI Gom 2), V2 (BWMRI Gom 3) and V3 (BARI Gom 32) and another four treatments e.g., T1 (control), T2 (50% Chemical fertilizer + 2 t /ha biochar), T3 (50% Chemical fertilizer + 2 t /ha trichoderma) and T4 (50% Chemical fertilizer + 2 t /ha rice husk). The experiment was laid out in a Randomized Complete Block Design (RCBD) . Parameters like plant height, number of tillers plant-1, number of leaves plant-1, spike length, fresh weight plant-1, dry weight plant-1, 1000 seeds weight, grain yield, straw yield, biological yield and harvest index were influenced by biochar, trichoderma, rice husk and chemical fertilizers. The BWMRI Gom 3 was found to significantly superior than BWMRI Gom 2 and BARI Gom 32 in terms of 1000 seeds weight (35.06g), grain yield (4.11 t ha-1), biological yield (8.35 t ha-1) and harvest index (48.77 %). T3 (50% Chemical fertilizer + 2 t /ha trichoderma) showed best performance than the other treatment combinations in most of the parameters specially in 1000 seed weight (38.46g) and grain yield (5.53 t ha-1), biological yield (8.84 t ha-1), harvest index (53.70%). Interaction result showed that BWMRI Gom 3 along with T3 (50% Chemical fertilizer + 2 t /ha trichoderma) possed the highest grain yield 5.47 t ha-1. Therefore, it can be suggested that the combined use of chemical fertilizers with Trichoderma for the improving of growth, yield attributes and yield of wheat in Bangladesh.
