Abstract
Seed rate and nitrogen fertilization are two main critical factors that affect wheat (Triticum aestivum L.) growth and yield. But a little knowledge on the interaction effects of these two factors in wheat cultivation under course, strong acidic nutrient deficit soil condition aimed us to conduct this research. We grew wheat at the field laboratory of the department of Agronomy and Haor Agriculture, Sylhet Agricultural University, Sylhet-3100, Bangladesh, during crop growing period (November-March) of wheat 2021-2022 with split plot design assigning seed rate (100, 120, 140 & 160 kg ha-1) in main plot and nitrogen fertilizer (0, 120, 140, 160 & 180 kg ha-1) in sub plot. The maximum grain yield (3.0 t ha-1) was obtained at 140 kg ha-1 and 160 kg ha-1 seeding rate and nitrogen fertilization respectively. Whereas, the minimum grain yield (1.5 t ha-1) was recorded in control treatment (100 kg ha-1 seed with zero nitrogen). The highest value of the entire yield contributing parameters i.e. effective tillers plant-1 (2.9), spike length (14.7 cm), spikelet spike-1 (17.0), florets spike-1 (52.3), grain spike-1 (51.0) and 1000 seed weight (42.6 g) were recorded at 140 kg ha-1 and 160 kg ha-1 seeding rate and nitrogen fertilization respectively and the values were increased with the increase of seeding rate and nitrogen fertilization rate upto 140 kg ha-1 and 160 kg ha-1 respectively then declined. The growth parameter i.e. plant height (114.1 cm) increased with the increase of seeding rate 160 kg ha-1 and nitrogen fertilization upto 160 kg ha-1 and the minimum value (54.1 cm) was recorded at control treatment.
