ABSTRACT

A field experiment was carried out in the Experimental Farm at El-Khattara region, Facutly of Agricutlure, Zagazig University, Egypt during two successive seasons (2018/2019 and 2019/2020) to study the response of wheat (Triticum aestivum L. cv. Shandwel 1) to micronutrients foliar spraying (Zn+Mn+Fe) compared with spray of water under two compost rates (0 and 12 ton ha⁻¹) and three nitrogen (N) levels (0, 145 and 290 kg N ha⁻¹). Micronutrients foliar spraying significantly increased most yield attributes as well as N uptake. The incorporation of compost produced significant increase in yield attributes as well as N uptake except 1000-grain weight and harvest index. The grain, straw, and total yields ha⁻¹ responded to each N increment up to 290 kg N ha⁻¹, but, harvest index and nitrogen agronomic efficiency responded to only 145 kg N ha⁻¹.

摘要

连续两个季节（2018/2019 和 2019/2020）在埃及扎加齐格大学农业学院 El-Khattara 地区的实验农场进行了田间试验，以研究小麦（Triticum aestivum L. cv. Shandwel 1) 与在两种堆肥率（0 和 12 吨 ha ^-1）和三种氮 (N) 水平（0、145 和 290 kg N ha ^-1）下喷水相比，叶面喷洒微量营养素（Zn+Mn+Fe））。微量营养素叶面喷洒显着增加了大多数产量属性以及氮吸收。除了 1000 粒重和收获指数外，堆肥的掺入显着增加了产量属性和 N 吸收。粮食、秸秆和总产量 ha ⁻¹对高达 290 kg N ha ^{-1 的}每个 N 增量有反应，但是，收获指数和氮农艺效率仅对 145 kg N ha ^{-1 有反应}。
