Protein Contents of Maize Varieties (QPM and Normal Maize) as Influenced by Nitrogen and Micronutrients

Abstract

ABSTRACT) and two rates of cocktail micronutrient mixtures. These were tested in a randomized complete block design with three replications and the treatments were factorially combined. The results from the study revealed that micronutrients application increased the lysine and tryptophan content of the QPM varieties since values were increased by it. The result showed that addition of nitrogen fertilizer and micronutrients increased the crude protein content of the maize varieties and so also with micronutrients addition the QPM varieties differed significantly from each other with respect to lysine and tryptophan contents (p< 0.05).It can be inferred from this that though normal maize and QPM varieties could be exposed to the same environmental conditions and take up same amounts of micronutrients, the QPM varieties have genetic capacity to synthesize high levels of amino acids and so would have nutritionally higher quality grains. Plant breeders therefore may found this attribute useful in genetic manipulation and cultivar development for enhance protein biochemical components.

Agro-biological Characteristics and Biochemical Parameters of Purple Waxy Corn [Zea mays (L.) var certaina] in Son La Province, Vietnam

“…SM8 recorded the highest protein content at 8.53% the second highest protein content is SM1 variety at 8.42% and the lowest protein content is SM5 variety with significant different at LSD (0.05). Similarly, Olowookere et al (2017) has given protein content of maize grain from 5.8-13.5% depends on cultivars and environment. Anthocyanins are important bioactive substances and good for human health, found in purple corns (Zea mays L.) Anthocyanins are natural pigments, have strong antioxidant potential and the ability to scavenge oxygen free radicals (Tian et al, 2018).…”
