Abstract
This paper presents the results of a study on the effects of red light treatment of sweet corn seeds on the quantity and quality of the subsequent yield (total and marketable), as well as the length of cobs and thousand kernel weight. The respective groups of kernels were exposed to light: 1—once (K1), 2—twice (K2), and 3—thrice (K3); the control seeds were untreated. The light treatment had a positive impact on the analyzed values. Relative to the control, we observed a yield increase of approx. 5% for the Basin cultivar and approx. 25% for the Shaker and Powerhouse cultivars under the K2 mode. We also recorded an increase in the percentage of marketable yield of approx. 20%, 45%, and 48%, respectively for the Shaker, Powerhouse, and Basin cultivars. Positive effects were also observed in terms of cob length and thousand kernel weight for all treatment modes and cultivars analyzed. The obtained results support the inclusion of this method in the scope of recommendable agrotechnical practices aimed at improving the quantity and quality of yields of various crops and vegetables.
Highlights
IntroductionIts kernels are rich in protein, saccharose, as well as various vitamins and minerals [1]
Corn is among the most widespread cereals cultivated worldwide
Literature reports seem to indicate that the corn yields obtained from seeds subjected to blue laser light treatment were better than those recorded after treatment with other laser light types
Summary
Its kernels are rich in protein, saccharose, as well as various vitamins and minerals [1]. It is widely used in human nutrition and provides a valuable source of good quality livestock fodder. The growth, quality, and quantity of yields are influenced by weather conditions, temperatures during the vegetation stage, as well as the applied agrotechnical treatment and fertilization. Suppression of corn growth is often due to excessive watering. Disproportionate availability of water results in kernels filling up and limits root growth [2,3]. Sweet corn, at the onset of vegetation, is ill-equipped to effectively compete with weeds, which can reduce yield by up to 85% and hamper overall quality of corn produce [2,4]
