Precision nitrogen management in wheat (Triticum aestivum L.) for enhanced growth and yield by green seeker tool

Abstract

A field experiment was conducted during Rabi season of 2023-24 at Agricultural Research Farm, Department of Agronomy, R.B.S. College, Bichpuri, Agra (U.P.) the investigation entitled ‘Precision Nitrogen Management in Wheat (Triticum aestivum L.) for enhanced Growth and Yield by Green Seeker Tool. The Variables involved in this study were nine different treatments of N doses viz. T1-Zero N, T2-150 N (50:50:50), T3-75-75 GS, T4-0-75 GS, T5-25-25 GS, T6-50-50 GS, T7-25-50 GS, T8-60-60 GS and T8-N rich (70:70:70). Thus, in all nine treatments were compared in a randomized block design (RBD) with three replications. Green Seeker-based nutrient management in wheat clearly indicates that precision nitrogen application significantly enhances crop productivity and resource use efficiency. Among the treatments, T2 (150 N-50-50-50) was the most effective, producing the highest biological yield (147.48 q ha⁻¹), grain yield (62.80 q ha⁻¹), and straw yield (84.68 q ha⁻¹) with a harvest index of 42.57%. This superior performance can be attributed to the balanced nitrogen supply across critical growth stages, ensuring optimal plant growth and yield.
