Abstract

A pilot study in the field was conducted within the study station of the Field Crops Department / College of Agricultural Engineering Sciences / “University of Baghdad during winter season of 2022-2023” .In order to find out the role of chlorophyll nutrient spraying on some growth traits of two varieties of bread wheat. Using RCBD design. The results showed a significant superiority of the V1 variety in all studied traits such as (Plant height measured in centimeters, number of tillers per square meter, and dry weight flowering100%, “the growth rate of the crop is g.m2.d-1, the hay yield in “ton .ha-1 biological yield ton. ha-1”, flag leaf area (cm2), chlorophyll concentration (SPAD), dry weight flag leaf g. , flag leaf' specific gravity (g.), spike length (cm) which amounted to (100.04 cm, 281.34 g .m2.d-1, 242 .06 g.m2.d-1, 5.96 ton. ha, 11.79 ton .ha , 32.68 cm, 48.73 SPAD , 0.131 g. , 0.0039 g. and 12.13 cm). respectively . comparative V2 . chlorophyll nutrient concentrations showed that the level of Ch1 (1500) mg. L-1 represented a considerable improvement in most of which comprise the following attributes “plant height cm”, “number of tillers m2”, dry weight at flowering 100% g.m2, “crop growth rate g. m2.d-1, yield of straw ton. ha., The biological yield ton. ha., flag leaf area (cm), chlorophyll concentrations (SPAD) and spike length (cm) that reached (93.15 cm, 315.00 tillers m2, 257.08 g.m2, 1.904 g.m2, 5.96 ton. ha., 12.85 ton. ha. , 29.30 cm, and 12.07 cm) respectively, compared to the concentrations of Ch2 and Ch3.

根据 "扎多克 "进化标准喷洒叶绿素对两种面包小麦品种生长特性的影响

2022-2023 年冬季，在巴格达大学农业工程科学学院大田作物系研究站内进行了一项田间试验研究，目的是了解叶绿素营养喷洒对两个面包小麦品种某些生长特性的影响。采用 RCBD 设计。结果表明，V1 品种在所有研究性状上都有明显优势，如（株高以厘米为单位、每平方米分蘖数、开花干重 100%、作物生长速率 g.m2.d-1、干草产量吨.公顷-1、生物产量吨.公顷-1、旗叶面积（平方厘米）、叶绿素浓度（SPAD）、旗叶干重 g.m2.d-1、旗叶比重（g.m2.叶绿素营养浓度比较 V2 表明，Ch1（1500）mg.L-1）的水平显著提高了大部分指标，包括 "株高厘米"、"分蘖数平方米"、开花干重 100% g.m2、"作物生长速率 g.m2.d-1、秸秆产量吨/公顷"、生物产量吨/公顷、旗叶面积（厘米）、叶绿素浓度（SPAD）和穗长（厘米）分别达到 93.15 厘米、315.00 分蘖平方米、257.08 克平方米、1.904 克平方米、5.96 吨/公顷、12.85 吨/公顷、29.30 厘米和 12.85 厘米。与 Ch2 和 Ch3 的浓度相比，分别达到了 93.15 厘米、315.00 分蘖平方米、257.08 克平方米、1.904 克平方米、5.96 吨公顷、12.85 吨公顷和 29.30 厘米。
