abstract
Wheat stands as a primary grain crop globally, used for food in human and feed for animals. The aim of this research was to investigate the impact of split application of nitrogen at different growth stages of early sown wheat (Triticum aestivum L.). The study was conducted at the Agricultural Research Farm of Maharishi Markandeshwar (DU), located in Mullana, Ambala, throughout the Rabi season of 2022-23. A Randomized block design was implemented, featuring three replications and eight treatments with a nitrogen application of 150 kg ha^-1 at sowing time and also divided into two and three parts.A number of parameters, such as height of the plant (cm), tiller counts m^-2, accumulation of dry matter (g plant^-1), 1000 grains weight (g), length of spike (cm) and yield of grain (q ha^-1) were recorded. The results indicated that the maximum height of plant (100.33 cm), tiller counts m^-2 (383.67), dry matter accumulation (25.53 g plant^-1), 1000 grains weight (46.87 g), spike length (9.5 cm) and yield of grain (48.97 q/ha) were recorded with three split applications of N 50% at sowing time, 25% at CRI and 25% at late jointing stage (T₆). Further results indicated that split application of nitrogen both two and three splits demonstrated improvement when compared to the control plots that did not receive any fertilizerand also where 100% RDN was administered to the crops at the time of planting.
