The Interaction Effect of Nitrogen Levels on Growth Characteristic of Wheat Crop (Triticum aestivum L.)

Abstract

The present research work was carried at the Agronomy Farm, Department of Agronomy, Narendra Deva University of Agriculture and Technology, Narendra Nagar (Kumarganj) Faizabad (U.P.), during Rabi season of 2014-2015. This farm is located at a distance of 42 Km. from Faizabad district headquarters at Faizabad – Raibareilly road. The ANOVA of the research trail used a design: randomized block design (factorial) to evaluate growth traits, comprising of initial plant population, plant height (cm), number of shoots (m-2). The data indeed suggested that initial plant population was not significantly influenced by either variety levels or nitrogen levels. Contrastingly, the data showed that variety levels and nitrogen levels significantly affected plant height at 30, 60, 90 days after sowing (DAS) and at harvest. The number of shoots at 30 DAS was not affected significantly by variety levels and nitrogen levels in the data. In addition, Variety levels showed a significant effect on the shoot number at 60 and 90 DAS and also at harvest stage, while nitrogen levels did not show significant effects in growth attributes of wheat under study.
