Response of wheat to foliar application of micronutrients in Northern Sudan [electronic resource].

Includes reference.

Foliar sprays are widely used to apply micronutrients for many crops. The advantage of the technique is the direct uptake of nutrients into the metabolism of the plant tissues which will in turn, asses the availability of nutrients to crops for obtaining higher yield. This experiment was conducted to study the response of wheat (Triticum aestivum L. var. Ammam) yield and yield components to foliar application of micronutrient mixture for two successive seasons (2006/07 and 2007/08) in the farm of the Faculty of Agriculture, Nile Valley University, Darmali, Northern Sudan. The experiment was arranged in a randomized complete block design with three replications. Treatments consisted of six rates (0, 4, 6, 8, 10 and 12 kg/ha) of a mixture of micronutrients (Mn 6%, eu 2.4%, Zn 3.0% and Fe 1.6%). Parameters recorded included: 2 spikes/m , spike length (em), 2 biological yield/m , grain weight/spike, harvest index, 1000kernel weight and seed yield per unit area. Significant increases in number 2 of spikes/m , biological yield, grain weight/spike, harvest index, 1000kernel weight and grain yield of wheat were obtained as a result of micronutrient foliar application. The results of this work revealed that high wheat yield and yield components could be obtained by the foliar application of micronutrient at the rate of 8-10 kg/ha at the research site and that the maximum biological yield, harvest index, 1000-kernel weight and grain yield were achieved by the same foliar application at the rate of 10 kg/ha.
