Title : Field evaluation of nitrogen and growth regulator treatments on wheat productivity
Abstract:
To fulfil future food demands, it is imperative to increase the productivity of wheat (Triticum aestivum L.), a crucial cereal crop in India. The purpose of this study was to evaluate how wheat growth and yield were affected by varying nitrogen levels and foliar application of the plant growth regulator Lihocin. At the Crop Research Station in Masodha, Acharya Narendra Deva University of Agriculture and Technology, Ayodhya, Uttar Pradesh, India, a field experiment was carried out during the 2019–20 Rabi season. Ten treatments and three replications were used in the randomized block design experiment. The nitrogen levels ranged from 0% to 150% of the prescribed dose, and the first node and boot leaf phases were conducted with and without Lihocin spray. The treatment that produced the maximum plant height (69.8 cm), tiller number (340.6 m?²), dry matter accumulation (1435.0 g m?²), leaf area index (5.20), and grain yield (5.48 t ha?¹) was 150% nitrogen plus Lihocin spray, according to the results. This was followed by 125% nitrogen + Lihocin. These results show that applying Lihocin in conjunction with greater nitrogen dosages greatly enhances wheat production and growth. To maximize wheat yield under comparable agroclimatic circumstances, farmers are advised to apply 150% of the required nitrogen dose in addition to Lihocin spray during critical growth stages.
