IMPACT OF FERTILIZER AND AZOTOPEX - AC ON LEAF BLIGHT DISEASE AND GROWTH ATTRIBUTES OF WHEAT

Abstract

BARI GOM-33 is a high-yielding variety of wheat that can respond to fertilizer combinations and biological approaches. The leaf blight of wheat caused by Bipolaris sorokiana is now a great threat for wheat cultivars in warm and humid regions of the world. Randomized complete block design (RCBD) with four replications is used in this experiment. Four treatments are, viz., T1 = 100% FRG recommended doses(control); T2 = FRG recommended dose (40% urea + 100% TSP + 100% MoP) + Azotopex-AC; T3 = FRG recommended dose (75% urea + 100% TSP + 100% MoP) + Azotopex-AC; T4=FRG recommended dose (60% urea + 100% TSP + 100% MoP) + Azotopex-AC; and T5 = farmer‘s practice (Urea-650g, TSP-550g, MoP-450g, Zipsum-300g, Magnesium and Boron-30g) were evaluated against Azotopex-AC was used in this experiment. Additionally, the lowest quantity of black-pointed seed was detected in T2. This study suggested that the combined application of fertilizers with Azotopex-AC shown good result against leaf blight of wheat. And growth attributes of wheat are also improved. T4 was observed to be the best in terms and yield attributing characters compared to other treatments.
