RESUMEN
A study was conducted to investigate the “Performance of seed rate on wheat crop (Triticum aestivum L.) Under late Sown Condition.” This experiment was carried out during the Rabi seasons of 2018-2019 and 2019-2 020 at the Pili-Kothi Student Research Farm and in the Laboratory Department of Agronomy at T.D.P.G. College Jaunpur. Increasing seed rates demonstrated a significant influence on various growth parameters, including initial plant population, shoot numbers, plant height, and dry matter production, with the highest values consistently observed at 140 kg/ha. In terms of yield-contributing characteristics, the 140 kg/ha seed rate led to increased spike counts, longer spikes, more grains per spike, and heavier grains. Yield significantly favored the 140 kg/ha rate, averaging 4.25-4.21 Mg/ha, surpassing the 120 kg/ha rate (4.08-4.07 Mg/ha) and markedly exceeding the 100 kg/ha rate (3.85-3.84 Mg/ha). The straw and biological yields further echoed this trend, cementing the prominence of the 140 kg/ha seed rate in augmenting late-sown wheat productivity.
