Growth, Nutrients Uptake and Grain Yield of Some Wheat Cultivars as Affected by Zinc Application Under Sandy Soil Conditions

Abstract

Two field experiments were carried out at Ismailia Exp. Sta., Agric. Res. Center, Ismailia governorate, during 2007/2008 and 2008/2009 seasons to study the influence of zinc application on growth, yield and yield components of some wheat (Triticum aesitivum L.) cultivars (Sakha-93, Sakha-94, Giza-168, Gemmeiza-9 and Gemmeiza-10). Three levels of Zn were applied: 0.0 (control), 1.5 and 3.0 kg Zn per Fed. Results showed that positive significant effects on growth traits, grain yield and its attributes was achieved by fertilizing wheat cultivars with 3.0 kg Zn/fed. Also, application of 3.0 kg Zn/fed. showed the highest values of P, K, Zn and Fe of shoot content. The largest flag leaf area was that of Sakha-93 and Gemmeiza-9 while, Giza-168 had superior shoot dry weight. Sakha-94 cultivar significantly surpasses all cultivars in plant height, while Gemmeiza-10 gave the highest number of spikes/m 2 , while 1000-grain weight of Sakha-93 was the largest. The highest grain yield was achieved with Sakha-94 and Gemmeiza-9.

Improving Grain Micronutrient Content of Durum Wheat (Triticum turgidum var. durum) through Agronomic Biofortification to Alleviate the Hidden Hunger

“…Wheat varieties respond differently to the application of micronutrients during growing period probably due to their difference in micronutrient use efficiency. It has been shown that one of the effective routes to improve grain mineral composition is the application of zinc-containing fertilizer either to the soil or applying foliarly and combined use of soil and foliar application [11]. Foliar application was perceived to be more effective in increasing grain Zn and Fe concentrations in different edible crops.…”

Effect of Foliar Application of Zinc on Growth and Yield of Wheat (Triticum aestivum)

“…However, there are different outcomes for wheat when Zinc fertilizers were applied. Many studies have shown that one of the effective ways to improvement in cereal is application of Zinc fertilizer [16], amongst all, foliar Zinc fertilizer is effective to improve grain yield [19]. The foliar application of Zn had positive significant effect on wheat grain yield and its components as well as quality of grains [14,20].…”

Zinc accumulation in wheat, and how it's affected by genetics and sulphate of zinc.

“…66, No. SI: 13 (2023) genetic biofortification using plant breeding or genetic engineering [11]. Malnutrition can be decreased by choosing plants that contain a high concentration of micronutrients and growing them using traditional agronomic biofortification techniques [12].…”
