Abstract:
A field study on the "Interactive Effect of Nitrogen and Phosphorus in Wheat Varieties in Effecting Use Efficiency And Crop Productivity" was conducted during the rabi season (2022-23) at the research farm in Dehradun, Uttarakhand. The study looked at how nitrogen and phosphorus (N & P) treatments affected the height and dry matter weight of wheat plants. The tallest plants, reaching 90 cm, were found in HI 1544, while the smallest, measuring 73.50 cm, were found in HI 8663. The three locations with the tallest plants were GW 366 (86 cm), half dosage of P (91 cm), and HI 1544 (88.50 cm). Lok 1 (3.64 g) had the highest average dry matter weight per plant, followed by Narmada 14 (2.72 g), HI8713 (1.77 g), and NARMADA 14 (2.98 g). The highest dry matter weights were found in Lok1 (3.64 g/plant) and LOK1 (3.64 g/plant), while the lowest was found in HI8737 (1.06 g/plant). It was also important to consider how long it took a plant to mature; among the nutritional treatments, some kinds took between 100.5 (HI8663) and 135 days (Narmada 14) to do so, which is a considerable time. The rate of variation development was slowest in control plots, followed by treatments employing reduced nitrogen, reduced phosphatic, and normal NP doses. The two locations with the highest harvest indices were HI1563 (50.35%) and lok1 (37.78%). The control treatment (70.82%) and the lower phosphorus dose treatment (69.83%) had the highest nitrogen harvest indices, respectively. HI8663's NHI (70.40%) has the second-highest NHI (85.16%).
