Effect of Different Levels of Phosphorus on Growth and Yield of Wheat cv. Shatabdi

Abstract

A field experiment was carried out in a farmer’s field of Gazipur, Bangladesh to evaluate the effect of various levels of phosphorous fertilizer on the growth and yield of wheat (cv. 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 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 plant-1, days to flowering, days to maturity, spike length, grains spike-1, grain yield, thousand grain weight, biological yield, and harvest index were recorded 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 tillers plant-1 (8.05), spike length (18.20 cm), grains spike-1 (42.08), thousand grain weight (36.16), grain yield plant-1 (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 treatment. The result of the study indicated that the 50 Kg P ha-1 would be effective and economic for the cultivation of wheat variety Shatabdi.
