Abstract
The field experiment was carried out at Agronomy farm, Acharya Narendra Dev University of Agriculture and technology Ayodhya during Rabi season 2023-24 and 2024-2025. The study aimed to evaluate the effect of seed rate with different nutrient management practices on uptake and yield of late sown wheat crop. The experiment followed a split plot design with four treatments in main plot and five treatments in sub plot. The purpose of the experiment was to examine the seed rate S1-100 kg ha-1, S2-125 kg ha-1, S3-150 kg ha-1 and S4-175 kg ha-1 with effects of five nutrient management practices N1-100% RDF, N2-FYM 10 t ha-1, N3-100% RDF + FYM 10 t ha-1, N4- 75% RDF + FYM (10 t ha-1) + Biofertilizer consortium 5 kg ha-1 and N5-50% RDF + FYM 10 t ha-1 + Biofertilizer consortium 5 kg ha-1 on uptake and yield of late sown wheat crop. Pooled data indicated application of nutrient management practices in which nutrient uptake S3 150 kg ha-1 indicated maximum uptake of available nutrient in grain and straw. Nitrogen (82.88 kg ha-1) and (34.92 kg ha-1), Phosphorus (17.18 kg ha-1) and (14.50 kg ha-1), Potassium(26.73 kg ha-1) and (78.68 kg ha-1), N475% RDF + FYM (10 t ha-1) + Biofertilizer consortium 5 kg ha-1 indicated highest uptake of available nutrient in grain and straw Nitrogen (92.08 kg ha-1) and (37.18 kg ha-1), Phosphorus (19.62 kg ha-1) and (17.59 kg ha-1) potassium (29.31 kg ha-1) and (83.22 kg ha-1). Under yield characters S3 150 kg ha-1 indicated highest grain yield (45.64 kg ha-1), straw yield (64.49 kg ha-1) and harvest index (41.36 kg ha-1). Although N4 75% RDF + FYM (10 t ha-1) + Biofertilizer consortium 5 kg ha-1indicated maximum grain yield (47.03 kg ha-1), straw yield (63.84 kg ha-1) and harvest index (42.35 kg ha-1) respectively.
