Abstract

Due to variations in the length of crop growth and the dynamics of soil nitrogen, the nitrogen (N) requirements of different wheat varieties may change. In this relation, during two successive wheat-growing seasons in 2018 and 2019, pot experiments were conducted to assess relationship among N fertilizer, yield and efficiency of N use in contemporary wheat varieties. Ten varieties of wheat viz. BARI Gom -24, BARI Gom -25, BARI Gom -26, BARI Gom -27, BARI Gom -28, BARI Gom -29, BARI Gom-30, BARI Gom-31, BARI Gom-32, and BARI Gom-33 and four N levels e.g. N 0, N 45 kg ha^-1, N 90 kg ha^-1 and N 135 kg ha^-1 were used in the study. Completely randomized design (CRD) was followed with three replications. Wheat yield and yield-contributing elements like spike length, 1000- grain weight, and grain yield enhanced at N levels up to N 90 kg ha^-1. The principal component analysis illustrated that the range BARI -32 had the most grain manufacturing and N use efficiency with N 90 kg ha^-1 application. Correlation depicted that there is a robust relation amongst N use, yield and N use efficiency. Dendrogram organized primarily based totally at the resemblance via way of means of Euclidean distance among wheat varieties and it was confirmed that varieties allocated in clusters II had been greater diverse. The end consequence found out big hereditary difference in wheat which could doubtlessly be used for the wide range cultivation and breeding plan.
