Abstract
A field experiment was carried out at the farmers field of Gazipur, Bangladesh to evaluate the effect of various level of phosphorous on the growth and yield of wheat (Shatabdi). The experiment consisted of four phosphorus levels, including a control: (i) T0 = 0 kg P ha-1 (Control), (ii) T1 = 25 kg P ha-1, (iii) T2 = 50 kg P ha-1, and (iv) T3 = 75 kg P ha-1. The experiment was conducted during from December 2021 to March 2022 in a randomized complete block design with three replications. Data on different growth and yield parameters like plant height, number of tillers per plant, days to flowering, days to maturity, spike length, grains per spike, grain yield, thousand grain weight, biological yield, and harvest index were collected according to plan. The different level of phosphorous showed significant effect on growth and yield of wheat. The T2 (50 kg P ha-1) treatment gave the tallest plant (85.25 cm), maximum number of tiller plant (8.05), spike length (18.20 cm), grains per spike (42.08), thousand grain weight (36.16), grain yield per plant (37.15 g), straw yield (07.46) and harvest index (50.72%). On the other hand, all the growth, yield and yield attributing characters were found lowest in control treatments. The result of the study indicated that the 50 Kg P/ha would be effective and economic for the cultivation of wheat variety cv Shatabdi.
