EFFECT OF NITROGEN (N) FERTILIZER TO YIELD AND YIELD CONTRIBUTING CHARACTERS OF BARI Gom30.

Abstract

to evaluate the effect of nitrogen (N) fertilizer on the yield and quality of wheat cv. BARI gom30. The experiment comprised four levels of Nitrogen (N) viz., 0, 50, 100, 150 kg/ha. The experiment was laid out in a randomized complete block design with three replications. The experimental result showed that there were significant differences in grain yield and straw yield due to the application of Nitrogen (N), although some of the yield attributes were not found significant. The highest plant height (96.23 cm), number of total tillers/plant (4.58), number of effective tillers/plant (4.00), spike length (10.16 cm), number of fertile spikelets/spike (48.92), number of grains/panicle (20.11), 1000-grain weight (49.78 g), grain yield (5.25 t/ha) and straw yield (6.30 t/ha) were obtained from 100 kg N/ha. The lowest plant height (84.00cm), number of effective tillers/plant (2.33), grain yield (4.25 t/ha) and straw yield (5.42 t/ha) were observed with the application of 0 kg N/ha. The highest number of sterile spikelets/spike (3.17) was found under control and highest harvest index (46.50%) was obtained from 150 kg N/ha. The overall results of the present study demonstrated that wheat may be grown successfully for obtaining maximum yield with the application of 100 kg N/ha.

Assessing the influence of integrated nutrient management on growth performance of aromatic fine rice

“…Moreover, increased in plant height in response to recommended dose of fertilizer might be primarily due to the improved vegetative growth and supplementary contribution of nitrogen (Awan et al, 2011). In contrast, it has been also reported that, application of higher amount of nitrogenous fertilizer increased plant height, tiller number, panicle length in wheat plant (Gismy et al, 2020). However, Mahmud et al (2016) reported that, combined use of vermicompost and NPKS fertilizer increased plant height, tiller number, flag leaf length and panicle length of rice plant.…”

Influence of Organic and Inorganic Nitrogen on the Growth and Yield of Wheat

“…The entire area planted with wheat was 332274 ha in 2019 and 3289224 ha in 2020 [4]. It comprises for 4% of the overall cropped land and 11% of the rabi crop area, which together produce 7% of all food cereal output [5]. As very large number of people are crossing the low income line day by day the increasing demand of food grains is rising in Bangladesh as well [1].…”

“…Numerous researchers found that N positively affects wheat yield and yield-contributing traits. If N is scarce, the plant may not respond as well to other nutrients, which could result in lower yield" [5]. Therefore, the most crucial component for successful wheat development and yield is N. It also shows an imperative part to increase photosynthetic processes, leaf area production, net assimilation rate, greater productivity results from the plant's capacity for tillering, food quality and as a result an adequate supply of nitrogen increases the protein content and nutritional value of grains as well as their backing characteristics [6][7][8].…”
